Condensing boiler – Wikipedia
- Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency 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 drain. In many countries, the use of condensing boilers is compulsory or encouraged with financial incentives.
Combustion Efficiency and Excess Air

Boiler – Wikipedia
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation.
Are electric boilers better than gas boilers? – VHL
Electric boilers work under the same principle as traditional gas boilers, other than the fact that they use electricity to heat the water rather than gas. This makes them an ideal option for properties which have no access to mains gas supply or which have gas boiler restrictions, such as listed buildings or bed-sits, giving the benefits of wet central heating without the need for a gas supply.There are several electric boiler manufacturers in the …See more on villageheating.co.uk
