Awards & Accreditations
Correct system design for installations
It is essential that the right boiler size is selected to meet the heating requirements of a property. Installing too small a boiler will cause numerous problems for both the householder and their heating system. Meanwhile, oversizing a system and installing too large a boiler is highly inefficient because the boiler’s output will be greater than what the property requires. This is why correct system design is so important and crucial for achieving maximum system efficiency throughout a home.
