DEVIcomfort Heating Mat - Installation

  • Installation is a relatively simple affair, first measure your floor in rectangles to see how many mats you’ll be needing.  If installing over concrete floors, it is advisable to lay insulation boards to minimise heat loss, ensuring quicker warm up times. Lay the first run of the mat, cut it at the end (leaving the cable intact), then turn the mat through 90 degrees or 180 degrees and continue laying. 
  • When done laying, attach the mat to the subfloor using the special tape provided. Install a Residual Current Device (RCD) fused spur to power the controller/ programmer and the mat system. Lay out the timer-thermostat onto the floor, with an equal distance between the two cable loops, then attach it to the floor surface. 
  • Now take the unheated power supply from the end of the mat system, which ought to be positioned near the thermostat. Once all connections have been sourced to the power supply, run the heater to ensure they are running properly (for no more than 10 minutes).
  • Lay a thin self-levelling screed over the mat, and then leave it to dry. After this, place the tiles or trowel flexible adhesive directly over the mat before laying the floor tiles over. Once you have completed the grouting, leave the tile adhesive to cool before turning the system on.

Typical areas for installation are Concrete floors, Indoor floor heating in domestic and public buildings, Very thin floors - perfect for renovating projects.

The Beginners' Guide To Heating Solutions

The method of heating your property is vital, whether that’s your home or commercial property. The best heating solutions will keep you warm, significantly reduce your electricity bills and lower your environmental footprint, so it’s important to choose wisely.There are dozens of types of heating solutions to choose from and sometimes it can be overwhelming. If you’re looking for a new heating system or are considering making a switch to a different system entirely, it’s always the best idea to evaluate the various options on the market.Gas heating systems are generally the most common heating method in England, Wales and Scotland. However, over four million homes across the UK are off the main gas grid. Blocks of flats and units make up a great deal of them, and they’re often looking for alternatives to gas central heating.Luckily, there are a variety of heating choices available that both commercial enterprises and residential properties can take advantage of, whether they’re on or off the gas grid. Below, we’ve outlined a beginner’s guide to the different heating solutions on the market.We’ve structured this guide as follows:Central Heating: An IntroductionWhat is Central Heating?Types of Central Heating SystemsGas Central HeatingElectric Central HeatingOil Central HeatingLPG Central Heating5 Main Types of Heating SolutionsElectric BoilersUnderfloor Heating SystemsCeiling HeatersWall HeatersStorage HeatersSo, what is the best heating solution for my property?Central Heating: An IntroductionBefore we get into the nitty-gritty and the different types of heating solutions, the first thing you should determine is whether you require a central heating system or something more localised. It is important to know the difference so that you can select a heating system most appropriate to your property.What is Central Heating?Central heating is a system designed to distribute warmth throughout a building. It typically does this by creating heat at a certain point in the property and spreading it throughout the rest of the building usually through water, steam or air. Many systems also distribute hot water across the property.This means that one central heater is installed at a certain part of the property, such as in a garage or a wardrobe. When it is switched on, it proceeds to distribute heat through ducts.You can usually mix central heating with different systems in order to manage the entire climate of the building. This is done through the operation of HVAC (Heating, Ventilation, and Air Conditioning) systems.Central heating is different from localised heating, which refers to only heating one particular spot in your property (such as a living room or one room in your office).Types of Central Heating SystemsBelow, we’ll outline the types of central heating systems you need to know about.Gas Central HeatingIf your property is connected to the natural gas grid, then a gas central heating system is likely going to be the most viable system to choose.Your central heating would normally be powered by gas ducted heaters or a gas-fired boiler, which provides heat for your entire home. You would have a boiler that would burn methane gas extracted from the gas mains.You will sometimes hear gas heat systems referred to as wet systems, which will typically heat up your water using radiators or underfloor heating.Pros of gas central heating – Gas is incredibly efficient, and you’ll often get a good return on the money you put in of ever energy unit you use. Storage costs are minimal, when compared to LPG and oil (outlined below).Cons of gas central heating – Many properties are not on the grid, meaning gas is often not often a choice. While you can get a good return on your investment, it is still expensive given the UK have a limited amount to go around. It is also a fossil fuel and contributes harmful carbon to the environment.Electric Central HeatingIf you’re not on the gas grid (like a huge number of properties in the UK), you could consider a number of electric heating solutions. Nearly every home has access to an electricity grid, so this is one of the more popular alternatives to gas central heating.There are many different types of electric heaters available on the market, but one of our favourites is storage heaters – this is one of the most cost-effective heating solutions which you can use to distribute warmth at night.While they are a little expensive, they can help you reduce your energy bill, especially during winter. Think of having a boiler that is a kettle, except it heats much more than just a cup of tea.Pros of electric central heating – Electric heating systems are much easier (and, therefore cheaper) to install than regular gas heat systems. It also requires less maintenance, doesn’t need an annual service and is widely available across the UK.Cons of electric central heating – Unfortunately, electricity is about 3 to 4 times more expensive than gas. Electricity is generated in gas-powered stations. Gas prices are going up – which means so is electricity.Oil Central HeatingOil central heating also relies on boiler systems, which is an excellent solution if you are not connected to the main gas grid. Boiler systems you can purchase today are highly efficient devices, but you should know that there are different types of oil you can purchase.Oil type C2 is probably the most affordable kind of oil on the market because it just uses kerosene.Kerosene is the most common kind of fuel used across UK properties. It also doesn’t ‘gel’ as much as other types of oil (in other words, crystals are less likely to form to prevent the oil from flowing – which can happen in the colder months)Oil type D is a more expensive oil, and is more commonly seen in commercial premises or large properties.Pros of oil central heating – oil is incredibly efficient, and a great alternative to both gas and electric heating systems if you don’t have access to those grids. Heating oil will also burn faster and doesn’t generate as much carbon as your traditional gas system.Cons of oil central heating – it’s more expensive than natural gas. There’s also no central infrastructure in place to facilitate an oil system, so you’ll need your own independent storage tank. Oil boilers may also be slower at creating warmth than a gas boiler.LPG Central HeatingLiquid petroleum gas (LPG) works similarly to gas heating but is highly effective if you can’t get a gas heat system. A big difference, however, is that LPG is delivered straight to your door (rather than brought in from pipes under the water).Liquid petroleum gas (LPG) heating is produced by a propane or butane boiler. These boilers will heat your water and spread warmth throughout your property through underfloor heating and radiators.Pros of LPG central heating – it’s highly efficient, and also you’ll get a great return on each unit of energy that your heating system uses.Cons of LPG central heating – LPG is costly, and that cost has escalated recently. Because LPG is delivered to you, the usual risk of something going wrong in transit exists – bad weather, traffic delays and theft. 5 Main Types of Heating SolutionsWhether you have a central heating system or a more localised heater, there is no singular way to have a heating system installed throughout your home.There are different ways to set one up. Below, we’ll outline the 5 heating solutions that we think are some of the most effective.Electric BoilersElectric boilers work with running water being heated by electricity. Once the water is heated, it passes through the remainder of your property’s heating system and can warm your home, office or industrial complex with the temperature you choose.Overall, these boilers are excellent for both central heating and localised heating solutions.Types of electric boilersThere are different types of electric boilers that you’ll come across on the market, such as:Combi boilers – combi (short for ‘combination’) boilers are arguably the most popular boiler in the whole of the UK. This is probably because they are extremely economical, and only heat the water that you actually use (and not just all of your water generally).Regular boilers – also known as a ‘heat-only’ or conventional boiler, the regular boiler will send hot water to your radiators and your hot water cylinder (even if you don’t actually end up using that water).System boilers – these boilers are similar to conventional boilers, but they take up less space.Which one you pick depends on your property, your budget and your heating goals, but no doubt the potential for an excellent electric heating solution lies with one of these boilers.Underfloor Heating SystemsUnderfloor heating systems are (obviously) designed to heat your property from underneath the floors. As hot air rises, warmth is then spread throughout the property evenly.This type of heating system is especially effective in places like:bathrooms;rooms with a lot of foot traffic;rooms with cold floors; androoms with high ceilings.Underfloor heaters can be easily installed underneath most materials, especially laminate, concrete and wooden floors. They can also either come as self-adhesive mesh, heating mats or heating cables.Buy Underfloor Heating Mats at SparksTypes of Underfloor HeatersThere are two types of underfloor heating systems you should know about, before making your decision to purchase one.Electric is the most common, and involves heating your floors with a mat, mesh or electric cable.Hydronic involves installing heating pipes in your home and heating the floors with hot water. These tend to be much more expensive than electric underfloor heating systems.What floor coverings are suitable for underfloor heating?Below, we’ll outline the different underfloor heating systems for different floor materials.TimberWooden floors are certainly suitable for a heating system to distribute warmth. However, it’s vital (before you install any wooden underfloor heating system) that the humidity of your timber does not drop to the point where the floor begins to shrink or wrap. You’ll generally want to make sure the temperature does not go any higher than 27°C (unless another temperature is specified by your manufacturer).ConcreteConcrete has a high level of thermal mass (i.e. the ability to store heat). Therefore, a concrete underfloor heating solution is highly effective because the floor itself will capture and retain the heat. This will make sure your flooring and your property stay warm for a long time after your heating is turned off.LaminateLaminate is made up of multiple layers of wood that run in opposite directions. Unlike traditional hardwood timber, it is more stable. This means it can tolerate the various changes in your heating system. However, it is generally recommended not to turn up any laminate heating to over 27°C (unless the manufacturer has stated otherwise).Ceiling HeatersCeiling heaters are, as the name suggests, heaters installed in the ceiling of your property. They are ideal to install in retail outlets, shops, offices, conference rooms and other areas or places where multiple people get together on a regular basis.Unlike underfloor heating, the main benefit of a ceiling heater is that it can distribute warmth without any obstacles in the way. It won’t be blocked by furniture or thick carpets.If your ceiling is between 2.5 and 3.5 metres – you can use low-temperature ceiling heating, generally anywhere between 26°C and 38°C.If your ceiling is higher than 3.5 metres – then you’ll need a higher flow of temperature. We’d recommend both wall heating (discussed below) and ceiling heating.Buy Ceiling Heaters at SparksWall HeatersWall heaters are the ideal solution if you’re looking for a more localised (as opposed to central) heating solution – in other words, they’ll heat up a concentrated area rather than the entire property. The heaters can heat up fairly quickly, providing the immediately desired heat.Wall heaters are quick and simple to install. All you’ll need to do is plug them into a powerpoint, angle it correctly and away you go. There’s generally no need for any expert consultation, although a professional can help you find the best spot to ensure the unit operates at its optimum capacity.Wall heaters have much cheaper costs upfront, as opposed to an underflooring system.At Sparks Direct, we have an impressive range of wall heaters and patio heaters, if you’re looking to heat up an outdoor seating area.Storage HeatersStorage heaters are designed to store heat during the day so that they can warm your property during the night. The main benefit is that it can reduce your electricity costs significantly, especially in winter.They are a little more expensive compared to other hearing solutions, but they’re a great investment if you need to use electricity in off-peak times.Buy Storage Heaters at SparksSo, what is the best heating solution for my property?At the end of the day, this is the question you’re looking to answer.Ideally, you’re going to want the most energy-efficient system for your property, helping you reduce your energy bills as much as you can while also keeping you and any occupants of your property warm and cosy.If you need any advice on what heating solutions are best for your property, please don’t hesitate to give the experts at Sparks Direct a call.

How DEVImat Electrical Underfloor Heating Warms up Homes and Shops (showcases)

The pioneering DEVI has an illustrious history in electric underfloor heating - being the first company of its kind - established in Copenhagen, Denmark in 1942. They became the leading electrical heating manufacturer in the market, and are now considered the best within the industry. Accordingly, they have a loyal customer base that is always growing - perhaps finding the 20-year full warranty (on certain purchases such as the DEVImat) with the 'DEVIwarranty' to be the icing on the cake. So this winter,  there's only one company to turn to when the question of underfloor heating arises. DEVI can provide you with an outstanding range of DEVImats of all sizes for your convenience, plus DEVIreg thermostats that offer hassle-free heating control. The combination of these two DEVI products is a match made in heaven, as outlined in this article here. If you need more convincing, we will dazzle you with select showcases of some of DEVI's most distinguished success stories - from apartments in the UK to Middle Eastern cold stores.Case Study 1: Cambridge Marque Residential buildings When first introduced in 2015, Cambridge's Marque residential buildings were touted as representing an 'iconic addition to an old city'. At 2697 square feet, it is easily the tallest residential building in the eminent city and boasts a luxurious layout. There are plenty of life-enhancing facilities on offer, such as secure underground parking, residents-only gym, a private garden plus a 24 hour concierge service. Naturally, the next deluxe addition for the project was some wonderful underfloor bathroom heating for the Marque's residents: and DEVI were first on the list for the job. The products were all quickly installed with minimal issues and complications by the DEVI UK team.  The Marque's Head of Electric Center said of the job DEVI had implemented: DEVI managed to get a large quantity of mats on the site at short notice... DEVI has been extremely helpful and thorough in assisting me throughout the project. Our contractor... has been very pleased with the quality and ease of installing the DEVIcomfort and Thermostat. Buy Devireg Thermostats and Underfloor HeatingCase Study 2: The Energy Plus House in Denmark Solar panels powering and heating a house during the freezing cold winter months in Scandinavia, where the sun never shines? Sounds a tricky proposition. Well, the Energy+ House in Norway has gone some distance to achieving this goal, even managing to produce more heat than it receives. It does this with the help of - you guessed it - DEVImat electric underfloor heating and a ventilation system with heat recovery. The combined heating and ventilation system are controlled via a single panel and is able to run maintenance free. What's more is that the Energy+ house requires no special structures and is apparently replicable in all types of buildings. The Energy+ House massively benefits from the DEVILink system, a two way communication system that can all be easily controlled from an optimally placed colour touch screen. The system provides complete floor heat control combined with room sensors to afford occupants with the highest levels of comfort. This results in substantial energy savings due to the individually adjusted periods of temperature lowering - a key factor for achieving a healthy and comfortable climate in modern homes. Case study 3: DEVImat Underfloor Heating in a Panda Store in Jeddah, Saudi Arabia One of the Middle East's largest cold stores, a 'Panda' store in Jeddah, Saudi Arabia, has been outfitted with DEVI complete protection system. This was quite an undertaking, as temperatures can drop to -30 degrees Celsius across this vast expanse of retail area, and inadequate heating could lead to the loss of huge amounts of frost-exposed produce. The total size of the project is 8,000 m2 and the total installed power consumption is approximately 160kW. It was completed without a hitch and a representative of Danfoss Dubai stated, regarding the unqualified success of the undertaking, that: We are glad that DEVI was chosen as the reliable partner for the construction of the biggest Middle Eastern cold store... we strongly believe that DEVI meets all expectations and demands required by such large construction projects Buy Devimat Underfloor Heating MatsSo is DEVImat definitely the antidote for freezing floors this crispy Christmas season? The three case studies given in this article were a few among many. DEVI has consistently proven itself to be a reliable and the most sought-after electrical heating specialist on the globe. But are they are good fit for your home? The answer is quite simply, yes. We here at Sparks can offer DEVImats, DEVIcomforts and DEVIregs at extremely affordable prices, with easy installation (as demonstrated in this article here), and excellent communication between DEVI products across any type of building. A short video guide for DEVI underfloor installation:  DEVI aim their products at members of the general public above anyone else, even with the grand-scale projects exampled in this article, and should be your first port of call for underfloor heating this Christmas!

Debunking the most Common 6 Myths on Electrical Floor Heating Installation

Floor heating has been known and loved by many for a very long time now. Even ancient Romans liked this simple comfort and used circulating warm water under their marble floors in order to have warm floors. Nowadays the electrical floor heating solutions provided by DEVI are not only comfortable but also energy-efficient with a huge focus on environmental friendliness. However, we often hear a lot of myths about floor heating, and many of them concern installation. Let’s dispel the most common six myths about electrical heating installation. Myth 1: Electrical floor heating is complicated to install. Not true. Heating mats are a solution that can easily be mounted whether it is on new or old sub-floors. The installation time will be the same, regardless of the type of flooring under which the system is installed. Also, the heating cables offered by DEVI are easy to install especially when the newly designed DEVI Turntable is used. Installers proved that using the DEVI Turntable makes the installation of the DEVIflex or DEVIsafe cables much faster and easier. Myth 2: Floor heating can only be used in bathrooms Wrong! Electric floor heating can be used in all types of rooms such as bedrooms, kitchens, and hallways. Nowadays, thanks to modern thermostats (such as the DEVIreg Touch), floor heating is often used as a reliable and energy-efficient solution of choice for all types of buildings (including low-energy houses). You can easily install electrical floor heating in newly built houses as well as existing ones during renovation. The DEVI floor heating is often preferred and installed in residential, apartment blocks, renovated buildings, and public buildings. Myth 3: Electric floor heating can only be installed under terracotta Wrong again. Floor heating can be installed under lots of different types of flooring. DEVI electrical heating solutions do not take up any space, which allows designing a space in each room as you please. You can install the DEVImats under any wooden floors, concrete floors, or even laminate floors.Buy Underfloor Heating Mats Myth 4: A fault means that you have to rip up the whole floor Not quite. The DEVI heating cables have a very long lifetime; they come with a 20-year warranty. But in case of any misfortune, there is no need to rip up the whole floor. The problem can be pinpointed to a few centimeters of accuracy so that only one or two tiles (for example) have to be removed to make a repair possible. Nevertheless, if this needs to be done, in the case of a rare fault, the DEVI warranty of 20 years covers full floor repair. Myth 5: Using electrical heating is the most environmentally unfriendly way of heating Not true. An electrically heated house with electric floor heating and solar cells fulfills the requirements of the EU Building Performance Directive. The electrical house is cost-competitive since it needs no other energy sources apart from electricity and fresh water. This is why nowadays electric heating is the solution of choice for low-energy houses. Regarding the fact that the EU expects that 65% of electricity production will come from solar cells, wind, and nuclear energy in 2020, electrical heating is clearly the preferable choice. Improving the energy performance of buildings is a particularly critical step in reducing the EU’s carbon footprint. Myth 6: Using electrical heating for outdoor heating is a high-cost solution Not really. For example, the DEVI outdoor heating systems are equipped with energy-efficient and cost-reducing, advanced intelligent thermostats that automatically regulate the system based on the actual temperature and humidity conditions. In cold but dry weather, the system remains inactive, saving energy and costs. When the weather is cold and wet, the system is automatically activated, quickly melting snow and preventing the build-up of ice. Nevertheless, you always have the option to manually control the system via the thermostat. An outdoor heating system from DEVI is quick to install, easy to control and inexpensive to operate. The desired snow and ice prevention effect can be fully achieved by installing cables only in those areas that are most susceptible to major build-ups of snow and ice, for example where buildings meet each other, around exposed downpipes or at points where the most melt water is channeled. You can purchase DEVI underfloor heating from Sparks Electrical Wholesalers either via our showroom in North London or online at the Underfloor Heating Systems section.Underfloor Heating Mats at Sparks
