What are the variables when using your Heat Output Calculator?
The BTU requirements of a room are determined by a number of variables. These include:
- The number of external walls that the room has
- The type of floor
- The size of the windows
- What is above and below the room
- Whether windows are double glazed
- Ceiling height
- Size of the room
- Type of wall insulation if any
When using a BTU or Heat Output calculator, simply enter the answers to the questions into the boxes provided to determine the BTUs of the radiator you need for each of your rooms. This will vary from room type to room type.
For example a small room with one external wall, i.e. a cloakroom, will have much lower BTU requirements than a lounge on the end of the house with two external walls and three windows.
Some other factors that can improve heat efficiency are:
- Insulation under flooring will help the room to retain heat
- Using blinds as well as curtains for large windows will prevent heat loss
- Cellars are cheap rooms to heat as underground rooms help maintain a constant temperature
- In period houses where wood windows are in tact but are not double glazed, draft excluder tape is a cheap and easy way to help prevent heat loss.
Our Radiator Chooser goes a step further than a simple BTU or Heat Output calculator. As well as giving you the results of your BTU calculation, it will also list the styles of radiators from our selection, including our Victorian cast iron radiators and simple column style, that are suitable for your particular use. Most of the styles can be made to a wide variety of BTU requirements but any especially high requirements are best met with a radiator with an increased number of columns (so the depth will be greater) so that the width of the radiator isn’t too ungainly.
