Electric boilers: what you need to know
Electric boilers are nearly 100% energy-efficient – compared to a like-for-like gas boiler, you need fewer units of energy (kWh) to produce the same amount of heat. Have fewer moving parts – reducing the likelihood of a fault. Quieter than gas boilers – mainly due to fewer moving parts.
