What KW oil radiator do I need?

**Beezerk** · 31-10-17, 10:01 PM

I'm slowly gathering stuff for my loft grow and my next step is getting some sort of heater in there. Room (within a room for better control) will be 1.6M x 1.6M x 1.5/1.8 high, temps should be ok with the light on but I'm concerned when they are off as it is getting rather cold up in the loft.
I have a small blower heater thing I was thinking of using but I've read oil filled radiators are much better.
Does anyone have experience with these ie what size radiator should I get?

Cheers.

500w oil rad shud see you well mate. Have it plugged in to timer for lights off on low setting

I use i leccy fan heater wired in to ecotechnics fan controller crackin peice kit. Set the lowest temps you wana let it go to on lights off an once it hits it say 17 degree it will kick in fan heater till hits your next desired max temp

But i did use a oil rad till i bought that. My flower tent 1.2 x.12

Nice one, thanks mate. May try my fan heater first, wired through a separate thermostat to see how I get on.

A 500w oil filled prob will not be enough in a loft. You might be better off getting more kw so you can adjust to suit the outdoor temps that will be dropping. In My shed i struggled to keep temps up and down i would imagine a loft to be the same if not well insulated.

i use a convection heater now ,did try a oil one but it failed to adjust the overall temperature quickly enough specially when it needed to also combat very low temp "air-in" during proper winter.
ive used a fan type as well at one point but in the end it was costing a fortune in leccy n i got pissed off with the whirring noise lol.
