I seem to be constantly buying and wiring up greenhouse heaters, came

they do

Anyone found an electric greenhouse heater that I can wire into a
separate
thermostat that lasts more that a couple of winters? Preferably not
one that
costs a fortune as some I've seen.



I use a domestic fan heater with a built in thermostat. It is set to
about 10 degrees C. Before the greenhouse it was running in my fish
house fro about 20 years so a relatively dry greenhouse is no problem.

My problem is I also grow a few orchids so the humidity is highish which
tends to rot stuff. I would have thought that heaters advertised as
Greenhouse Heaters would be made to cope with greenhouse conditions but
it appears not so.

I used to be into tropical fish too, had 5 largish tanks at one time and
bred a few species just for the fun of it.

Have you thought of Gas from cylinders (Large red ones)?
These heaters have a thermostat built in and are good, I use several in
conjunction with electric heaters
