What is the formula for working out kilowatts required for each room for a central heating system?

Get the volume of the room in sq ft. Multiply that by 4.5 for room with 1 external wall, by 5 for rooms with two external walls. this will give you required btu per room.

Its not the kilowatts that determine the heat in a room.
What you need to calculate is the BTU's required.
This is done by calculating the cubic area and matching against the Btu output of a particular radiator.
One can also split the Btu's required into different radiators with a smaller output.
e.g. Btu's required 46, radiator 1, has an out put of 23 and radiator 2, has an output of 23 =46 Btu's.
This gives you an opportunity to place radiators where they will be most effective,(under windows to reduce chill) or most aesthetic.
Most good radiator companies provide a Btu calculator on their websites.

First you have to find the heat loss for each room. This takes a professional to do what is called a load calculation. After that is done, you match the load for that room to a radiator or combination of radiators for that room. For more info check out the load calculation page at my source.

Radiators are ultimate placed at present below residing house windows to steer away from a foul black mark coming up above them on the wall. an determination is to mount a small shelf above it. Radiators are sized via their output in BTU's. you like the mandatory BTU's to warmth the room based on the mandatory temperature boost, the size of the room and the losses. To get the mandatory BTU's you want a definite floor area of radiator. Doubles cut back the size. to in good shape the gap, you oftentimes have a sort of sizes that have a similar output. i.e. greater width, much less height or greater height and much less width.

Search central heating calculators on the web, when you get past the sales pitches there will be a table calculator on several sites.

you need to measure the cubic volume of each room ..that is the width by the lengh.by the height .. go to your plumbers merchants and they have a calcs charts for different size rooms

Unsure but in my house each window has a raditor underneath it the same lenght. Probably a shite answer but my house is always warm!!
