Regular visual inspection and servicing, every three years, by a qualified technician are sufficient for the efficient maintenance of your solar water heater and for your system to work properly.
A heating audit is a test carried out as part of the regulations on the energy performance of buildings (EPB). This audit is mandatory for central heating boilers over 15 years old and has to be carried out by an approved specialist.
Yes and no. The answer to this question depends on how the electricity is generated.
A central heating stove combines the best of both worlds: the cosiness and heat of a stove or hearth and the hot water production of a central heating boiler. In some cases, the central heating stove can replace your regular boiler.
