What is the heat output ?
Maximum heat output from screeded floors is approximately 100 W/m2, the maximum heat output from timber suspended floor and floating floor is 70 W/m2. With there being higher standards of insulation in new buildings, average heat requirements for many buildings are now below 60 W/m2. For small bathrooms it is standard practice to also install warm water towel rails to give extra heat output as these areas are usually not very large.
