Chris asked [quote]I have a log cabin 5m x 2.5m, what size heater would you recommend[/quote]
You don’t say whether you have any other form of heating in the cabin. Assuming not, when considering which RugBuddy Under Rug Heater for Log Cabin, the short answer is: fit the largest that you can on your available floor space.
RugBuddy is designed as form of secondary heating but if your cabin is well insulated you may get away with relying purely on RugBuddy if you can cover most of the floor area. Its output is 125 Watts/ m2 which compares with underfloor heating systems for laminate and wood floors rated at 110 W/m2
It’s OK to place tables or chairs on the rug, with the RugBuddy under it, but you don’t want anything on it that smothers it, e.g. a bean bag or mattress.
So if the size you describe is totally available, with just tables and chairs to position on top, I would go for 3 of the 1.5 x 2.3m size and lay them side by side. They’re each rated at 450 watts so shouldn’t overload your electrics, but you may want to check this first.
If not all the floor is availiable, or you have a primary source of heating, just choose a RugBuddy that will fit under a rug wher you spend most of your time – typically in front of your chair/ sofa.
Hope this helps!
