Gas Boilers: A Quick Guide | Ideal Boile

That means that less heat energy – and therefore less gas – is needed to heat the water up to its operating temperature. All new boilers are required by law to be condensing boilers, and this law came into effect for gas boilers in 2005 (or 2007 for oil boilers). So if your boiler is newer than that, it should already be a condensing boiler.

Condensing boiler - Wikiped

2019-10-2 · Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted. This condensed vapour leaves the system in liquid form, via a

Steam boilers must heat the water to a higher temperature, and therefore have lower efficiencies than hot water boilers. Natural-gas-fired boilers are more efficient than oil-fired boilers. Combination boilers combine water heating and heat generation in one unit and can save considerable money on heating and water heating costs.
