I don't want to cause you grief but I had done staple up on a bedroom and an ensuite bathroom over a garage. The garage was heated but only to about 10 Deg C. It was a 1/2 poly-b tube on a 6" centre to centre with R28 fibreglass insulation beneath. The house is extremely well insulated.
The room was uncomfortably cold here in our Canadian climate. The water circulated was 80 Deg. C. and offered up no appreciatable heat.
The rooms have been changed to above subfloor Uponor system.
The balance of the system is in slab and now with 40 Deg C. (Geo and solar heated) water which is absolute nirvana.
Just a word of caution. Again I don't wish any ill will.
If your going forward and the work is complete I pray to the in-floor heating gods your result will be markedly better!!
