Hello, at the moment I am heating my greenhouse by a 3 kw Electric heater. but
the electric bill is getting rather large!

I am thinking of switching to a Propane Gas heater of 2 - 3 kw, has anybody any
thoughts about this?

Thank you,

Tony.

what about Paraffin?

My Mum gets 4 gallons each autumn from what's left in the paraffin tank
in our stock room and that does her all winter.

Although her greenhouse is only a small one.

Why heat the whole greenhouse? I am currently bringing on approx 250
Busy Lizzies and 100 Geraniums in an electrically heated propagator
(within a greenhouse). This is a bed of sand with an insulated base and
an 80W soil warming cable. On top is a 4' x 2' cold frame insulated
with bubble plastic. In a worst case scenario with external temp below
zero, the air temp in the propagator is always above 8C. I have used
this system for 4 or 5 years and have had no problems.

Regarding Gas, this makes a great deal of moisture in the air, so will need
well ventilating, which rather negates the purpose.
As far as electric is concerned, assuming you are aware of the saftey needs,
3Kw sounds a bit OTT, I have used a 700w convector heater this year, on a
timer, 1 hour on 1 hour off, even with -5c havent lost any plants or
seedlings yet.

You don't. You put an extra bit of wood in, across the glass if required,
but firmly fixed to the firm structure, and fit the socket to that.

By the mode of question, I guess you are DIY. Are you aware of the safety
implications here? Electricity has no respect for human skin and life. You
are only dead once. Electrics and water do not mix ............. unless you
know how and when and the greenhouse is not one of them

Yeah know how electrics just never seen sockets in an all glass house,
seen them on a brick/glass ones. How do you stick wood to a couple of
cms of aluminum which is very soft stuff?

Gas and paraffin also add wter vapour and CO2, which may be good for plants.

Lost cheaper than lectrickery

And I beleive current regs/law, is that this should be installed by a
qualified electrician, or checked by one, and a safety cert. issued. I'm
told cost of check and cert is around £80! Take care my friend.

He could do the same as dozens of other people and run an extension lead
down there, it will only be for 3 or 4 weeks at the most, once May gets here
it will be redundant.

Try Maplin or any real electrical supplier, and explain the problem.
They'll have an in-line waterproof connection set which won't need to be
attached to anything, just hung out of the way. You should be fused down
for power coming from the house wiring, of course (as if I ever
bothered!).

You don't 'stick' it, you fix it using the fixings of the greenhouse. I have
battens and shelving fitted to an Ali greenhouse.

Soft? High powered fast ferries are made of Ali. Life Boats are made of Ali.
With the proper support and fixings, Ali is very light and strong. Soft in
certain comparisons, but tough.

To what temp are you heating - a few degrees makes a lot of difference.
Is the Gh insulated with Bubble wrap etc., are you heating the whole lot
or have you partitioned off a bit?
