Hello. I am converting a former garage into an office. It's around 23 square metres. Ideally I would like to install underfloor heating on the wooden subfloor. Is this adequate for a primary heat source? I like the carbon mats but I'm not sure if they are powerful enough (160 Watts/sq m). I'd rather not have to use screed if possible, and I do not want to install any plumbing - electric only. What is the best way of doing it, and should I look at storage or solid fuel heaters instead?
Cheers.
Cheers.
