Hints & Tips

By turning down your room thermostat by 1deg from 21deg to 20deg could see savings of up to 10% off your energy bill.

If your radiators are cold at the top there is probably air in them. By bleeding the radiator you could see it working more efficiently.

Lime scale is a major problem when heating hot water. 1mm of scale can see efficiency reduced by 8%, by fitting a scale reducer or water softener you heating appliances can work more effectively for longer.

I was very impressed with the engineer from JC Heating in both his professionalism and interesting ideas such as solar heating and outside temperature sensors to make my heating more efficient. Other companies had only suggested a standard bish, bash, bosh job, and then they didn't even return a quote. I would trust anyone at JC Heating to offer and deliver the best solution for the job
