Hi, I have recently purchased a ladder radiator for my downstairs shower room. It came with an electric element (already fitted and sealed) and a thermostat I fitted separately.
Based on the measurements of the room and the passage way outside it (separated by a door), degree of insulation, outside walls, etc. I used two different BTU calculators. Result 1 gave a required BTU of 2,020 to 2,475 and Result 2 gave a required BTU of 2,155 BTU.
To be on the safe side, I chose a radiator that produced an output of 2,883 BTU see link: http://www.lunaspas.co.uk/acatalog/White_flat_electric_ladder_rail_1200.html
However, now I have fitted it, the heat output is useless! The radiator has to be on for say 6 hours before it is hand hot. The radiator barely takes the chill off the shower room (with the door shut).
I cannot see how I could go wrong wiring the thermostat and fixing the thermostat to the radiator is simply by tightening a plastic nut.
Have I misunderstood the BTU requirement?
Do the facts suggest that the radiator element could be faulty?
Your opinions would be appreciated before I contact the company.
Cheers.
