Further from our post about free domestic hot water..... No it really was not a joke!!!! This is how we realistically and affordably accomplish this free and or heavily reduced hot water gas bill
Conventional solar thermal systems work with a traditional boiler to maintain a stored supply of hot water. Regardless of demand, the boiler fires-up to replenish the stored water as soon as its volume or temperature deteriorates.
With SolarSmart, the stored volume of hot water is heated only by the collected solar energy, so no gas is used in maintaining the cylinder temperature.
Should the solar heated water be exhausted, however, the combination boiler fires-up long enough to help satisfy any immediate demand for hot water.
The boiler
Intec gs
A high efficiency combi boiler with a built in gas saver!
Positioned neatly above the boiler, this compact unit extracts heat from waste gases that are normally expelled into the atmosphere through the boiler flue. This is then used to preheat cold mains water before entering the boiler.
As the boiler is heating warmed water rather than cold, an average 35% less gas is used to produce hot water, reducing your energy bills and saving up to half a ton of carbon per year.
