The new standards apply only if you decide to change your existing hot-water central-heating boiler or if you decide to change to one of these boilers from another form of heating system.

Climate change has been caused by increasing amounts of carbon dioxide being released into the atmosphere. Around 16 per cent of the carbon dioxide that the UK produces comes from the gas and oil boilers that we use to heat our homes.

Many would argue that this is an over simplification, and of course there are many derivatives of each. Both hot water systems have different characteristics and some of the key issues for consideration include:
