[QUOTE="johnb2713, post: 545824, member: 35153"] The above are a bit of a dilemma. Solar can be good in the decent weather but in winter time about as much use as a chocolate teapot. With Octopus off peak at 7.5p, Solar-PV would have a very long break even point. If I were in your position, I would be looking at more battery storage and possibly bigger inverter, this would then allow you to run on 7.5p kWh throughout the day, recharging every night. Definitely add the Heatpump, 11kw of heat for 2.5 kW of electrical energy has got to be a winner and it would be easy to plumb in to the hot tub pipework, the circulating pump just needs to pass the water through the heatpump unit.
