Dimplex slimline storage heaters - the XL and XLS ranges (discontinued, see the XLE range)

The Dimplex XL and XLS ranges of storage heaters is the UK’s slimmest and most popular storage heaters, offering performance, economy, ultra slim design and maintenance free reliability, having manual & automatic input controls.

Note: the XL and XLS ranges of storage heaters from Dimplex have now been discontinued; see the Dimplex XLE range here, which is available.

The XL and XLS series from Dimplex are suitable for a wide range of domestic and commercial applications.

The heating level of XL range is adjusted by means of a variable input control, which the occupant sets in line with the changing weather conditions.

The automatic XLS range offers improved comfort, economy and ease of use, with a sophisticated automatic charging system to ensure the level of charge is adjusted to compensate for changing weather conditions without the need for user intervention.

At the heart of this system is the patented Twin Sensor®, which meets the requirements of Building Regulations Part L1, which requires all electric storage heaters installed in new build to be fitted with automatic charge controls.
