The solaredge is integrated with the mind of the solar pv system we have, so any excess solar will automatically heat the hot water with no input from us. The question to ask, is that worth 7x the cost of this?…Im not so sure.

Thankyou, Yes you can switch it on or off

Unfortunately I no longer have this fitted as have a solar integrated system now. This did work very well for the time I had it and was a good option cheap option.

You absolutely could, however consideration would be needed for battery storage sizing to accommodate such an increase in daily usage.

Yes it does, each room in 30mins-3hr or boost all for 1hr

I doesn’t have a direct integration, but it doesn’t need to. You set the schedule on this which will negate the need for your boiler to heat the water.

@@DIYJourney1 Thank you so much. But how does nest know if the tank is cold or hot without a thermostat please?

My tank has a temperature sensor so cuts the boiler off when its at the selected water temp. I anticipate most water tanks and boilers have a water temp adjustment on them. Therefore if your water has been heated via electricity the boiler will not heat using gas

@@DIYJourney1 Thank you. I have solar panels which heats up the cylinder through an immersion heater, and cylinder can be heated through boiler too. But the problem is I don't know how hot the cylinder is, and heat the water unnecessarily using gas or electricity override. If there was a gadget to measure the temperature of the water inside the cylinder, I can avoid this situation.

This T Smart Immersion thermostat measures the temperature of the water and you can see that on the app. You immersion will cut off when at temperate though but it is key to turn it off, not to waste power as you say.
