The Essential Guide to Electric Boiler Installation

Electric boiler running costs. When comparing electric boilers with units that run on gas and oil, the efficiency can cause some confusion. This is because electric boilers have an efficiency rating of 99- yet only have an ErP rating of C/D. Meanwhile, gas and oil boilers with efficiencies of 88-93% are awarded ErP A-ratings.
