turn down boiler in summer when I only need hot water?
I have a burnhan set at 160 deg / 180 deg and its too hot for DHW. I just bought a Watts mixer to set the max temp at 120deg.. But can I turn down the system in the summer to reduce cycle time? What if I have separate gas DHW heater, or go on vacation for a week.. can I shut the boiler off completely?
