Re: Low voltage greenhouse heating

Thanks Steve and all

I will forward the options over and go from there. The electrician seems to
think his conductivity whilst sitting a glorified bath is pretty good ;-))

Thanks

Ian

> So, does anyone have any bright ideas for low voltage heaters

You'll struggle to find a low voltage greenhouse heater because they tend
to be rated at about 1.5 ->2 kw and need to be to keep the temperature
above 3-4 degrees on a cold winter night.  So to achieve that output at 12
or 24v means you will be pulling near on 100 Amps.

Best bet it always to fit a normal 240v heater and go via a RCD.  An
electric shock requires somewhere between 80mA and 250mA (depends on how
well you are earthed and how conductive your skin is) so a 30mA RCD should
provide more than sufficient protection.
