Conservatory heater:
I was thinking along the lines of a gas wall heater such as a
Drugasar (only name I know for these heaters).

I've no experience of them. Would they go on a wall that is 600mm
high?


I suspect depends upon location and intended use. I have a south facing
aspect on a 25yo brick built house where I'm thinking of a 4x5m dwarf brick
wall and uPVC D/G. I could extend and drill through my gas heated CH at the
time of construction ( the boiler has the capacity) and I shall be putting
in a power supply for standard lighting/ TV/ light power use. At present I
am favouring not extending the CH and just relying upon an electric fan
heater for when we will occupy the space.

For that, when it's very cold, you may need two fan heaters of 2kW each
or at a pinch a 3kW may be enough.

I would do the heat loss calculations for it, but it will be in this
sort of range based on scaling from what I did.

If use will be occasional, then fan heaters are a reasonable solution.
Obviously it will get expensive for long periods of use, plus there is
the noise issue.
