how much heat will a paraffin heater give off?

I've got a 3 tear mini greenhouse and thought about a paraffin heater but didn't know how my chillies will grow if its about 5c outside. I heard it will add another 5c inside the greenhouse.

Do you mean one of the little plastic blowaways? Like this? 2ft3 x 1ft5 3 Tier Mini Greenhouse £13.95

Yup that's the one

In that case, I wouldn't advise using a paraffin heater.

Firstly, not enough room for one
Secondly, if you do manage to squeeze one in it will probably melt the cover

ventilation or lack of it is also an issue with those small blowaways.

I had one for a couple or three years and whilst I agree with the comments above I used the small Parasene anti frost heater with success. They are only about £15 and when turned down use very little in the way of parrafin.

Useless in a normal GH unless its sectioned off as they are only made for small spaces. Would not use a regular sized heater though.
