Top Tip
When measuring up for original pine doors always measure the door frame rather than the existing door. Take two measurements for the width and two for the height as a most door frames on period houses are a little wibbly wobbly. Use the largest measurement for the door size required.

Measuring Your Chimney Breast For A Fireplace Or Stove

Calculating Btu's To Heat A Room With Cast-Iron Radiators

Measuring Your Fireplace Breast

fireplace_measurements_diagram It is always helpful to know various measurements when selecting a new fireplace. This helps us to give the best advice to assist you in selecting the right size fireplace for your home. The line drawing to the left has been marked a to k, if you can make as many of these measurements before you visit the shop or call, it would be most helpful.
You can always print this page and fill in the spaces with your measurements if you find it useful.

A = Width of space on side of opening (take a measurement for both sides)

B = Depth of chimney breast

C = Height of chimney breast

D = Total width of chimney breast

E = Height of hearth

F = Depth of hearth

G = Total Width of Hearth (or old tiles / concrete that needs to be covered by the new hearth)

H = Opening Height of chamber

I = Opening Width of chamber

J & K = Distance from a structure like a light switch or window to the chimney breast

Working Out The BTU's Required To Heat A Room

You will be surprised by the heat efficiency of traditional cast-iron radiators; they are roughly 4 times as efficient as a single skin and twice as efficient as a double skin pressed steel radiator. This allows you to free up a fair amount of wall space when deciding where to position them.
Btu's are a measure of the heat output required to heat a room. This is useful to know when we are calculating the size of radiator required to fulfil your individual room heating requirements. There is a formula for calculating this and if my father was alive today he would work it out for me. However he is not and this link will do it for you.


Once you have calculated the requirements for each room it is worth thinking about where in the room you would like the radiator to be placed. Other points to consider are;
  • Are there any Height restrictions, e.g. is the radiator to be positioned under a bay window? What's the height from the floor to the bottom of the frame?
  • What is the width of the space available..
  • This helps us to determine what style of radiator would be best to fulfill your heat requirements
  • It's not too difficult, I promise.
  • If you need any help, please get in contact and we will talk you through it.
