The Benefits of a Solar iBoost

About Marlec

As a long established renewable energy company Marlec saw the requirement for a simple and reliable product to enable households to self consume more of their own power generation, we launched the renowned Solar iBoost in 2013 which became one of the best selling PV accessories in the UK market.

Solar iBoost diverts excess energy generated by a grid connected PV system to the immersion heater to provide free hot water and off-set the cost of heating the water by gas or electricity. Solar iBoost is extremely popular with installers and the public alike, who can maximise the benefit of their PV investment.
