This post is intended as a general guide for property owners/managers who are trying to assess whether they require a new boiler, and, if so, what type of boiler would be best for their needs.
What is a combi-boiler?
A combi boiler combines what a less sophisticated boiler and separate water tank/s do in one compact unit, saving you space and improving reliability.
What is a condensing boiler?
20-30% of the energy a non-condensing boiler uses is lost as water vapour and carbon dioxide bi-products escape via the flue (the ‘pipe’ that transports exhaust gases outside). Condensing boilers recover some of this lost energy by way of a heat exchanger, improving their efficiency by around 20%. Government legislation means that all boilers fitted after the 1st of April 2007 must be of the condensing variety.
