Use excess solar to generate hot water
To take advantage of a Hot Water Optimiser, the customer needs to have a hot water tank. This can be an old-style unit, typically found in the airing cupboard, or a modern hot water cylinder.
A hot water optimiser diverts electricity generated by your solar panels to heat water in a hot water tank via the immersion heater. It can be programmed to utilise excess generated electricity after a home-storage battery is fully charged, or prioritised, depending on your needs / preferences.
We will always consider recommending a hot-water optimiser, where applicable. If your tank is also heated using gas, be prepared for a big saving on your gas bill.
There are a number of products on the market, which we keep abreast of and recommend as needed. Two strong contenders are iBoost from Marlec and Eddi from MyEnergi, both UK Manufacturers
Essentially, a hot water optimiser can provide your household with free hot water for most of the year. This is a quick and economical way to make significantly higher savings on your energy bills. It ties in with the concept of using as much generated electricity as possible to maximise savings and minimise use of the supply network.
Hot water optimisation should pay for itself within 1-3 years, making substantial savings thereafter.
