Highly Efficient Boiler Installation

Oil and gas boilers have evolved a lot even in the last 10 years, the modern boilers on the market today are condensing boilers. If your boiler is more than 10 years old then you could be wasting up to 30% of the gas and oil fuel that the boiler burns. If you look at this in numbers, if you pay for £100 of gas or oil you could really only be getting £70 worth. Heating our homes accounts for 55% of energy bills per year, thus this upgrade could have a big effect.

High efficiency boilers are more friendly to our environment also, the new modern boilers have a reduced pollution level compared to previous models we used to install in our homes.

Your homes heating system when upgraded to a new boiler will also be compatible with modern day technology allowing you to control the hours your boiler operates at which will also contribute to the life span of your new boiler. Speak to the team today to discuss your options of smart heating controls.
