Choosing a replacement boiler

When selecting a new boiler you’ll need to consider:

For smaller houses with just one toilet or less extensive hot water needs, a combi-boiler might be a better alternative. The combi-boiler heats water on-demand and doesn’t get a hot water tank so that it may squeeze into smaller areas.

2) Which fuel to work with – this will probably be established by where you reside and which fuel you currently heat with. Gasoline is easily the most famous heating fuel within the UK; employed by 69% of houses, says the Department of Energy and Climate-change. In accordance with Which? gas is also the cheapest heat source. Electrical boilers and oil are somewhat more costly all around, but are great alternatives should you stay off the gas mains.

3) Which make of boiler you select – there are numerous well-known boiler manufacturers to select from such Ecogen as Vaillant, Baxi, Intergas etc. Look around to get the boiler for the property.
