Like I said before, it's entirely possible that we won't be able to get an ASHP since where we want to put the external unit might not be feasible . If that turns out to be the case we'll have to stick with a gas boiler for our heating. If that is the case then we may be able to afford PVs, which we could use to augment the heating system and/or heat our DHW, which would save cash and carbon. If that is the case, how would that be integrated into the heating system, since boiler-based heating loops don't have a tank that you can put an element in?
