floor standing (in the garage). It heats water, or runs the heating too. Not sure what that type is called, have a hot water tank/airing cupboard.
What should I changed to? Don’t want to change radiators, have 8, various sizes.
Not sure how old my boiler is. Want smaller but economical one. Maybe wall hanging type. Any advise please, including cost of supply and fit? Thank you.
A condensing boiler is one that recondenses the water vapur in the flue gasses to extract the latent heat of vaporisation which would otherwise be wasted to atmosphere. They are also known as High Efficiency boilers. A combi boiler is a boiler that does away with the need for a hot water cylinder or storage tank in the loft by heating water instantaneously within it as it flows through from the mains. A non combi boiler is one that is just a heat source used to heat external cylinder and radiators. Both combis and non combis can be made in high efficiency condensing versions, and indeed by law with very few exceptions you will need to fit the high efficiency version.
Cost depends on a lot of factors but you will need your rads and pipe-work cleaned prior to fitting of new boiler as the high efficiency heat exchangers are badly effected by scale and sludge.
