I am currently having problems with a conservatory company regarding the size of the electric under floor heating system they have installed. The Edwardian style conservatory has a floor area of just under 20 sq/m & the size of the heater mat they installed is 2.5Kw. Knowing a little about heat loss calculations for conventional household central heating systems, I queried if this was sufficient to provide the primary heat source & both they & the manufacturer stated it was.
With an outside air temperature of 10 degrees & without the influence heat migrating from the house or the sun, the temperature struggles up to around 18 degrees; if the outside temperature drops to 0 it will only hover around 14 degrees & sometimes drops even lower.
A representative of the heater manufacturer has checked the system & reported no faults but would not get drawn on the question of insufficient capacity. I have since been told by another supplier that he usually allows 0.2Kw per sq/m, which obviously makes the size of my heater look seriously deficient. I have a meeting with the installer & am not sure what stance they are going to take. I would appreciate any information regarding the calculation of electric under floor heating requirements as a primary heat source in conservatories?
