I have a Megaflo sealed hot water system, coupled to a standard oil fired
boiler. The system works fine, but occasionally switches off because the tank
thermostat has reached its operating temp. The stat is marked 10 - 70 degrees,
at what temp should I set it for the DHW?
Thanks in advance
Somewhere in the 55-60 region is considered normal - to be hot enough to be
useful without too much risk of scalding. I prefer 60 myself. Tank stats are
not always accurate. Having set mine, I usually measure the temperature of
the water coming out of the hot tap, using a mercury in glass thermometer -
and tweek the stat if necessary.
