“Founded in 1978 and based in Gillingham, Dorset, Dextra Lighting has grown to become a company of more than 500 employees receiving numerous awards including “Company of the year, Dorset”.

Industrial Heaters has been providing installation work and maintenance to Dextra Lighting since 2006 with quick response to any breakdowns reported.

During a recent visit it was found that a main component of the gas fired heater had failed leaving the unit beyond economical repair.


Using the heat loss software, we carried out a site survey and specified a suitable replacement. A Winterwarm HR condensing gas fired suspended heater was specified and installed. 

The existing vertical terminal which always have the potential for leaks in the future was capped and a new horizontal coaxial flue system installed. Control was provided by a Winterwarm Multitherm keypad operated timeclock and temperature controller.


The condensing Winterwarm HR high efficiency heaters are some of the most efficient available and are on the Governments list of energy efficient appliances. Therefore, they qualify for the enhanced capital allowance scheme, which is a Government initiative to encourage purchases of high efficiency equipment. This enables upfront tax relief so businesses can claim 100% of the cost in the first-year against their taxable profits. The Multitherm controller provides optimised start, frost protection and a pin facility to stop unauthorised use and energy wastage.
