Hi All,
I currently have a 3 year old gas combi boiler which provides hot water and central heating for our apartment. However Im looking to add a 100l AC electric hot water boiler into the hot water circuit in order to better use more of my solar generation and reduce my gas dependency. Central heating would still be performed by the gas boiler (for now), and the gas combi would still remain connected to the hot water circuit, but I would turn the water temp on the boiler to 0C so that doesnt heat.
This could be done in one of two ways, either pre or post the gas combi, I cant really see much difference in the two however but is that really the case? Its seems straightforward to plumb the electric tank into the hot water circuit with a three way valve, which would isolate the electric tank if necessary. Is there something important I'm missing here though?
I can easily do all the work myself, Im reasonably experienced with plumbing (including installing hot water tanks).
This is far as I can see is very rarely done, at least here in Europe, which considering its an excellent method for storing energy from my solar panels I was surprised about. It will save me at least 300 euros a year, plus less GHG emissions.
