Really hoping someone can help me out!
Live in a modern (5 yrs old) townhouse. (Lets call ground floor level 1).
Level 1 is freezing cold especially in winter. I foolishly tiled all throughout L1 on to conctrete without putting in underfloor heating but it's too late to do anything about that now. I have double sized patio doors & windows off the kitchen that I feel let a lot of heat escape due to their size. They are only covered (at night) by thin linen curtains. I have an integral garage though I have insulated and draught proofed the garage door.
Thermostat is on level 2. Levels 2-4 are absolutely fine temperature wise.
Every radiator has a TRV. Combi boiler on Level 3.
What is the problem?
Is it the thermostat on L2? If so is it a big job to relocate downstairs?
Is it just lack of covering on L1 windows? If so then I can sort that no probs obviously.
Will turning off the TRVs on Levels 2-4 and putting L1 on high work? Or will that eventually lead to the same problem just slower to heat the whole house?
A small point - L1 downstairs toilet is really toasty when heating is on as it's only a small enclosed area. This leads me to think it may be the back windows and doors (virtually a wall of glass).
Please help!!
Thanks, Dan.
