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.

Thanks for the comment. I agree with both aspects. I anticipate only
occasional use in evenings in early Spring / late Autumn and possibly during
mid day in winter to read the newspaper at weekends! Extending the CH under
the floor in essentially an "outbuilding" could be asking for fun when
trying to track a problem wih the CH at a later date is my current thought!
