Heating a summerhouse..

ChilliBob

Yeah, I did look at wood flooring, thinking engineered rather than laminate, which looked more like £40 a sqm before underlay, but I didn't give ig too much look. I just hate to take the hit on the tiles! 

Basically on one hand:
Write off £900
Have 34 tiles I realistically won't sell or do anything with, cost £700 to sit there and do nothing!

On the other hand:
* Buy more tiles, circa 700 quids worth
* Price to fit, with materials, is circa 3,000-3200 or so.

Heating wise, I'm not too fussed about the colder floor thinking how we would use it, but yeah, if I didn't have these tiles would I go for 20mm outdoor porcelain? Probably not! At £60sqm, erm no, very much doubt it!

36 square metres is going to take some heating, especially if it's low on insulation.  Add as much insulation as you possibly can to it.  

I would say use infrared heating because it heats the person, rather than the air, so you'll feel some benefit quicker.  I've had these recommended to me by someone else with a garden room - you'll have to do some kind of heat loss calculator for the wattage you'll need.

Underfloor heating would be a total nonsense. No insulation in the floor, very little elsewhere - you'd lose the heat before it had a chance to build.  

I'd also maybe reconsider using ceramic tiles in a space that isn't well heated, if you're sitting in there it will feel like it's sapping the heat from you because they're so cold to the touch.  Infrared heating may help with that, but heaters using convection will see your tiles being the very last thing to warm up - they'll act like an anti-radiator, almost! 

Agree 100% on infrared heaters ,went to a funeral recently, the weather was freezing cold but inside the church they had wall mounted infrared heaters ,was like being back on holiday in  Greece .
