Ok bit of background I have solar at home and have built a power wall . Still have excess 9 months of the year so want to heat some water for free, only snag have a combi boiler
Discovered mine will accept main water temp upto 60 Deg so thinking add a hot water tank before the boiler use less gas.
Only problem I want to ensure that the temp in the tank reaches 60 Deg at least 30 mins each day to limit bacteria
My solar system has mqtt do turning the heater on and off shouldn't be to hard.
Any recommendations for measuring the water temp ?
thanks all the design has changed I plan to heat some medium and have the water pass though a head exchanger what way standing water will never be consumed later
there is a commercial product called sunamp which is designed for this purpose
