Frequently Asked Questions

What is an energy efficient boiler?

An energy efficient boiler is an appliance which operates as effectively as possible as a result of an innovative design and clever technologies which enable the appliance to achieve maximum output for the fuel used. A high efficiency oil boiler will work efficiently and effectively, using less fuel which in turn can reduce heating bills for the householder. Not only does the reduced fuel usage result in lower heating and hot water running costs, but it is also more sustainable. 

Grant Condensing oil boilers, for example, achieve excellent efficiencies of up to 94.5% so a homeowner who installs a Vortex or VortexBlue can benefit from lower fuel usage and reduced heating bills.
