It is likely that replacement boilers will more often than not be sized incorrectly. Oversized boilers not only cost more to purchase but generally operate less efficiently. This results in higher running costs and increased carbon emissions to the atmosphere.

The 'whole house' procedure aims to provide a solution to this issue by providing you with a reasonably accurate method of boiler sizing which is both quick and easy to use.
