Hydroponics - yup

So its not to grow anything illegal but one of my elderly customers want to put some plug in devices in his green house so as and when the temperature drops, the heaters come on - any suggestions for something suitable for a hot / cold / damp / dry environment?

This "device" needs to sit between the sockets and a fused spur

Thanks

you want the old suntube heaters - not seen one for ages!  Low wattage, just enough to take the chill off the greenhouse.

My late farther in law wanted heating in his greenhouse for his tomato seedlings. So I built a hot bed for him. The first electricity bill arrived and it doubled that quarters consumption.

FWIW he's bought some "tube" type low wattage heaters ........... and wants to control the temperature they kick in at...

 

[binky]

so fit a thermostat.

Or a frost stat!

Surely the traditional "greenhouse" tube heater with a built-in thermostat should do the job?  Just google greenhouse tube heaters..

Tubular heaters are useless in a greenhouse, all the heat is lost. Later I used Reychem heat tape in the “hot bed”, I wouldn’t say it was great success but it worked in a sort of fashion.

Frank (FiL) also grew chrysanthemum flowers to show at competitions, that’s another story.

heating a greenhouse certainly wont do much for global warming... :lol:

He isn’t using a gas heater it’d burn the plants, think we are looking at electric!! 

No greenhouse gases here.

I use a fan heater with inbuilt thermostat carefully set to about 2 or three degrees. It doesn’t seem to have a drastic effect on our bills, but we are in a fairly mild  climate area.
