I have a solid fuel rayburn unpressurized gravity system with immersion hea
ter back up for summer use when the rayburns not in use. When the rayburns
running the hot water can get very hot, enough to cause the immersion therm
ostat cut out button to operate, this is a real pain as I have to reset it
in order to use the immersion. Is it possible to still obtain thermostats w
ithout safety cut out buttons?
I doubt it very much - there was a case a few years ago where someone
managed to boil their cylinder. It overflowed into the loft tank, and
heated that until the plastic softened. Whereupon a ton of lethally hot
water went through the ceiling. I think it was a child it killed.
There has to be a better solution, so I've cross-posted this to
somewhere more lively.
