Improve payback and returns significantly by making use of your free Solar PV power at home rather than exporting it to the grid.
Now there are units on the market which can deliver your excess PV electricity straight to your immersion heater, thus providing free hot water. In most cases this will be enough to heat an entire cylinder daily throughout the spring, summer and early autumn months, and even in winter it can still contribute to heating your cylinder and reducing the energy input required by your boiler.
These control units can be installed at the same time as a PV installation or retro-fitted at a later date. Monitoring home electricity consumption and Solar PV production at the same time and whenever there is surplus power recorded, that surplus is fed directly to the existing immersion heater rather than exporting it to the grid.
Please ask our team for more information on the best unit to suit your immersion electrical configuration.
