A leading builders merchant in Blackburn was looking for heating for its trade counter and showroom to replace the existing heating that had become largely ineffective.
This consisted of eight 3kW 15 year old overhead convector heaters that had largely become ineffective, unsightly and inefficient. As such they were seeking a cost effective long term solution that was aesthetically pleasing and showed a relatively quick return on investment. There were also four 2kW plug in portable heaters placed under desks and a 5kW overhead Halogen heater behind the counter during the colder periods.
These heaters were uncontrolled, with no thermostats, and on constantly from 7-30am until 5 pm (9.5 hrs).

Improved efficiency with a reduction in total energy consumed. Lower running time of Herschel heaters, a result of using thermostats to control the heating to the desired temperatures, as well as the benefit from the building retaining heat within the thermal mass and radiating back the warmth.
“We decided to switch to Herschel Infrared heating for our trade counter and showroom as our previous overhead heaters had become ineffective and were failing to keep our staff and customers warm. Different heater types were installed to suit each area and the installation was incredibly quick. Feedback from both staff and customers is that they are noticeably warmer when it’s cold so we are more than satisfied with the switch to Herschel Far Infrared heaters”.
