Title: Best polytunnel heater
Post by: suziequeue on May 14, 2013, 09:18:05 am
I am SOOO determined that my cucmbers aren't going to succumb to the cold this year.

We normally have a late frost in May which killed all my tender little cukes last year and we've got snow forecast for this afternoon  :o :rant:

So - I am planning to invest in a polytunel heater.

Does anybody have any experience/recommendations?

Probably not much help, but we're going to put a couple of hens in ours (in a house) over winter. Apparently the body heat is enough to warm the tunnel.

Hens :roflanim:the little b...s would scratch up everything and eat what they hadn't killed. I spend a lot of time keeping my free range darlings out of both flower and veg beds. Odd bits of plastic and netting everywhere :chook: but they still seem to get in, no wonder they warm it up with all that activity. Hmm perhaps a big cage at one end, I still think they may do more harm than good.

Word of warning regarding housing chickens inside the polytunnel.

The first year I tried it the covering was heavily scratched and torn probably by a fox knowing the were something inside.  This year netted to waist height all round.

As for the heat issue I still found that the water was frozen on the odd occassion.  Oh make sure that any overwintering items are well secured!

As for the heater, I have a propane one but due to the large volume required  to heat it eats the propane even just on low.

Yes - it would be a bit impractical with all my tomatoes and other veg planted out. :roflanim: :D

Could you install a rocket stove mass heater? Not expensive to make and don't need to worry too much about carbon monoxide as it's not going to be inside a house
