Heat output

[CharlieCat]

Please can someone help me work something out?

At the moment I have an open fire and I want to try and work out roughly the kw output from this fire. I know it won't be exact because no doubt it will depend on many things but if someone can just give me some idea.

I made a fire last night and within an hour the temperature in the room had increased by 6 degrees C. There was no other heat source. The size of the room is 16'x17'x9'.

Thanks very much.

It might be easier to tell us what end result your are trying to achieve.

What kind of gas meter do you have ? is it one with a dial or does it have numbers ?

 

[kevplumb]

methinks solid fuel picasso

size of fire and fuel mught help

If its solid then the only way to estimate the heta output is to have it off and run a 2 kW electric fire and record the temperature increase after about an hour.

Then use this figure to extrapolate to obtain the heat output from the solid fuel fire.

Sorry I didn't make myself clear.

I have a 16 inch open fire with a back boiler on which I burn Blue Flame smokeless fuel. I don't have central heating only this fire, 2 x 2kw oil filled radiators - one upstairs, one downstairs (I live in a one up, one down).

The suggestion has been made that I have a multi-fuel stove which would heat the water and run a radiator in the bedroom and a small one in the bathroom. After researching into this, the output to room with this type of central heating stove seems so low, I'm not convinced that I will be warm enough with just this stove downstairs.

I've been told that an average heat output for a 16inch open fire is 2.5kw but I think mine is warmer (which is why I asked the question).

 

[kevplumb]

its more dependant on the output of the back boiler

they usually have a flue at the rear

No, its not - what about the space heating? And the boiler is rated as amax. figure, and output depends on volume ang type of fuel

The back boiler in the open fire is approx 10,000btu.

The multi fuel stove I've been asked to consider is 8kw but the majority of that power is used to heat the water and radiators. The nominal output to room when burning solid fuel is 1.7kw with a max of 2.5kw. Although my house is only very small, the room with the fire/stove has 4 external walls and 2 3'x4' single glazed draughty windows and my concern is that I will be making the wrong decision in having my open fire removed.
