Radiator BTU Calculator

Although possibly seen as a daunting task, calculating your BTU requirements per room can be done by the Paladin Team and a full specification sheet provided with measurements for installation purposes once your radiator style has been chosen.

BTU is British Thermal Unit abbreviated and is the measurement of heat requirement to amply heat your room spaces.

All Paladin radiators have been British Standard tested for
quality and BTU efficiency.

In order for the Paladin Team to calculate your radiator BTU requirements we need the following information per room:

Room sizes, width, height and length
The number of outside walls each room has
The type of room it is ie kitchen, bedroom etc
The floor the room is situated on ie ground floor, second floor etc.
Double glazed or single glazed windows
Wall insulation or if not insulated we require the thickness of the walls.

Telephone or email the Paladin Team with this information per room and we can advise you on the size of radiator required. Each radiator is custom built for you and pressure tested ready for installation.

BTU is an abbreviation for British Thermal Units and most heat loss calculations are presented as BTU requirements or wattage requirements.

When calculating BTU requirements it is important to realise that a BTU calculation is important to get right and the best person to advise anyone is a plumbing or heating engineer on site or the Paladin Sales Team as each home is different with many variables that can affect the BTU calculation. A wrong BTU calculation for any room can leave you without sufficient heat during a cold snap or caused you to have wasted money on a radiator that is far too powerful for your room space.
If your radiators are chosen too large for each room space they will be less economical to run and indeed some installers will get around the complex issue of heat loss calculations by offering radiators that are too big and suggest thermostatic valves so you can turn the temperature down, this is not ideal.

The size of radiator required for a room space is dependent upon 2 factors, firstly the temperature that you want your radiators to be able to maintain which is a relatively straight forward task and secondly the heat loss from your room space. Heat loss calculations are not so straight forward and are quite complex as you need to consider many factors per room.

So which temperature do you want your individual room spaces to have? The recommended heat requirement for a lounge area is different to a bedroom area and most self calculate BTU calculators will work on 21 degrees centigrade for the living areas and 16 degrees centigrade for the sleeping room space.

Heat loss calculations are dependent upon several variables unique to your home, the wall insulation, number of windows and if they are double glazed or not, north or south facing position, the number of outside walls per room, and indeed the floor that the room is on as an upper floor will have less heat loss as hot air rises and it will benefit from the lower floor heated space. Not all self calculate BTU calculators available on various web sites will take into account all these factors. At Paladin we look at all the variables possible for each of your room spaces and advise you accordingly before choosing the size of radiator required for each room space.
