Case study 3 - Home Close Edge 68% Reduction in bills

In this example innovative combinations of technology were used to maximise the decarbonisation of a property that relied on an older oil power boiler. Solar panels, combined with a Solar Iboost assisted a Ideal logic pre plumbed dual coil cylinder allowing excess Solar energy to minimise water heating costs. While the primary heat demand itself is met by a Ideal Logic Air 5kw Air source heat pump.  A great example of how Retrofit can deliver life changing financial savings,.
