The response you received is almost identical to the one I got a few days ago. I'd be interested to know which route you took and how it went. I'm probably not going to export, but it might be helpful for future dealings with them (from my own perspective) if you took the G98 with the aim of them reinforcing the network (and they did). Did you make a decision yet? Also, and I know this is a very noob kinda question...on the G100 form, power station capacity is just the max that I can supply to the network, correct? so a 6kw inveter tied to a 10kwh battery with max output of 5kw), power station capacity would still only be 6kw? I only ask because the SPEN guy seems to be changing his mind and leading me on a merry dance.

Only 2 of the rooms are going to need heating over the winter and the requirement (can't find it at the time of writing) is so small that even a 4kw ASHP would be overkill. My thought was to use an aircon system instead then it can also be used for cooling in the summer. I realise this might seem counter-intuitive to save 1500 on a boiler, to then spend it on aircon, but it would definitely make the space more adaptable year round. I do plan on looping in the UFH as a "just in case" option for future, but the a/c puts out about 1200 BTU's, which should be more than enough to make each space comfortable even in the middle of winter.

Recently I was given a 14kw heat pump and associated cylinder. Now, we're putting up an outbuilding, it's 100sqm with walls at 0.1 and ceilings at 0.11 (sips build with superfoil). Obviously, the heat pump is going to be massive overkill to provide heating and DHW. However, I was wondering if anyone has just used the CYLINDER from a heat pump as an immersion heater for the DHW without connecting up the heat pump? It'd save me buying a new immersion heater at £1500, and I like the idea of using something I already have if at all possible. Any thoughts on whether this is possible? The heat pump is the puhz-hw140vha2 and the cylinder is ehpt25x-ukhcw. Any thoughts or ideas would be hugely welcome

Hi all, new to all this, including putting up buildings, but just about to throw up our first outbuilding (trying to figure out how to heat it), and then moving onto the main house with Enerphit in mind. Please help!
