[QUOTE="johnb2713, post: 532856, member: 35153"] I'm not convinced about the logic, why would I only want a tank a quarter full of hot water? If I'm using solarPV and/or off peak, fill it up completely. The heatpump ready bullet point is really a nonstarter, heatpumps use the indirect coil just like the gas boiler. Their 20% saving is only valid with a gas boiler thats cycling on and off and its an 'up to' 20%. I suspect the tank would be very expensive too, for something that offers no advantage in my eyes, I dont care about being able to heat the water up from my phone, all I want is when I turn on the shower, hot water is there. I had a new standard insulated tank installed when I needed to fit an immersion heater ready for the solar (the old tank the immersion was u/s but seized in). Looking at the EDDI data my tank appears to lose less than 15w when the water is at 85 deg C. I run it at high temperature and have a blending valve on the exit to drop the temperature to 50 degC. I may install and extra tank after I've run with my second battery for a while, hot water cylinder does work very well as an energy store. [/QUOTE]
