Greenhouse Heaters - Gas or Electric - Which is best?
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. |

I am thinking of switching to a Propane Gas heater of 2 - 3 kw, has anybody any thoughts about this? Thank you, Tony. 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. Malcolm |

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. regards Cineman "Redrose" wrote in message ...

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? |

I only wanted one for a heater but he said he knows me, I'll only want more for something - lights perhaps - in the future. Still haven't used the second. But I don't understand why water is any more of a problem in a greenhous than its anywhere else. Mary |

But I don't understand why water is any more of a problem in a greenhous than its anywhere else. It usually arrives when numpties install sockets at levels normally found in living rooms, IE about knee height, then forget, then during a dry spell go in there with a hosepipe, flash / bang /wallop, as they say. I have a double socket and a fluorescent light...I also have piped mains gas and have a small camp stove in there right now on the lowest setting with a steel shovel lying over the flame, which is around 3mm high, all of this is directly below a frame which is similar to Malcolm's mentioned above....the shovel gets hot but not so hot that it glows, I doubt if the gas used is as much as a pilot light on a boiler. |

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!). -- Mike. |

How do you stick wood to a couple of cms of aluminum which is very soft stuff? 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. |

writes Hello, at the moment I am heating my greenhouse how big? by a 3 kw Electric heater. but the electric bill is getting rather large! 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? -- Chris French |

If you use electric ensure its on an rcd, or for a permanent install, an rcbo for each circuit. Electrics in greenhouses are different to electrics in the house, and leakages due to water, damp, bugs and dirt are to be expected. Use toughened glass bulbs (eg PAR38), enclosed fittings, or preferably fl/cfl. GLS and halogen bulbs are liable to shatter. Bottled gas works well and is pretty safe. With 2 cylinders and a changeover valve you can ensure it doesnt freeze now and then and you dont waste gas. Paraffin is the cheapest, but isnt really safe. CO ouput is something they do unless you keep a proper eye on them at all times, a wick that isnt kept trimmed and shaped will produce CO. They can get knocked over. Nearly all are spill proof but if you screwed the cap on askew it wont be, and there are heaters that arent spill proof. Daytime ventilation before entering the greenhouse is good practice with paraffin. When these heaters were used in houses, deaths occurred. The 2 other options are solar thermal and insulation. A layer of polythene of bubble wrap will reduce heat loss day and night, and an external sheet of silvered mylar can reflect more heat and light in during the day. Raising daytime temp increases the night time minimum, more so if youve got insulation. Directing central heating boiler exhaust into the greenhouse is an effective option rarely used, and is as safe as portable gas heating. Might not be very effective if youve got a 95% efficient boiler though. Controlled house ventilation with the exhaust to the greenhouse is one last option. NT |
