How low can we hang a ceiling pendant before it becomes effectively useless?
Today, we wondered: how powerful a heater would we need to make this office a little bit warmer? The answer turned out to be simpler than we thought, and then it got more complicated (see a picture presentation of our affordable heating solutions for the office).
More Square Footage = More Wattage
Although your new heating system has thermostatic controls, that doesn't mean it will have sufficient power to heat the room to that temperature.Larger spaces need more heating power (and vice versa). for non-industrial purposes, it's best to think of it in terms of wattage per square foot.
Here's a quick and rough guide to the power needs of different-sized rooms (based on generally accepted stats and technical specs for Convector Heaters).
| Area of Room (square feet) | Recommended Heater Wattage |
| 50ft² | 350W |
| 100ft² | 900W |
| 150ft² | 1350W (1.35kW) |
| 200ft² | 1800W (1.8kW) |
| 300ft² | 2700W (2.7kW) |
| 400ft² | 3600W (3.6kW) |
| 500ft² | 4500W (4.5kW) |
| 800ft² | 7200W (7.2kW) |
| 1000ft² | 9000W (9kW) |

Some Relatively Uncommon Heating Applications
Over-door heaters such as the Dimplex AC3N, or "air curtains," are often used in commercial and retail spaces to combat cold draughts from open doors - and to keep out insects and other pests!Similarly, a floor heater such as the FFIH recessed floor heater can help keep out draughts that infiltrate a room from underneath the door.
This particular fitting doesn't even require an under-floor air supply; there are inlets and outlets on the grille face itself.
However, if it will face a lot of foot traffic, make sure it won't crack or break. Looking to more domestic applications, the plants in a greenhouse will often succumb to freezing temperatures in the winter, but these spaces do not require the same level of heating as, say, a similarly-sized bathroom.
In these cases, a thermostatic "frost protection" heater will heat the space to a relatively low temperature to keep those plants healthy.
These are just a few examples, of course, and everyone reading this will have different requirements that can't be summed up in a blog post.
