Condensing boilers in particular are designed to heat up your home and water as efficiently as possible. Not only is it now a requirement (as of 2005) for every newly fitted gas-fired boiler to be condensing, but it must also have an efficiency 'A' rating too. So, what is a condensing boiler and how does it compare to other options? This
