Rate of increase of room temperature

[Yikes]

What is a typical figure for the rate of increase in room temperature when a heating system starts up?

A friend of mine said it should be 4degC per hour but mine only manages about 1degC per hour between 6am and 9am.

Think that's an imponderable, eg type of heating, insulation, boiler temp, rad size, type, size of room, property type and so on.

Sure, but I wondered what other people are seeing?

I think there are far too many variables to make sweeping generalisations

today my living room 4 hours 18 minutes to go up 1c from 18.7 to 19.7 with an average flow temp of 28.6c using about 1.283kWh of gas with about 3.5 hours of burn time

Not seeing anything. I put more clothes on and seek out all air leaks and seal them. So far, no need for central heating. Major air leaks were in the exterior doors.

Thinking aloud, I would expect it to be exponential rather than linear.

That's around 367 watts per hour, you either have a TPI roomstat that's causing the boiler to cycle constantly or a problem with the boiler causing the recycling or WC if installed has set the target temp far too low which will also cause the boiler to cycle.
Yesterday morning , ambient of 1.0C, it took about 45 minutes to raise the temp from 18.1C to the digital stat setpoint of 19.0C thereafter it takes around 10 minutes to raise temp from its cut in at 18.85C to cut out at 19C and overshoot to 19.1C, oil firedboiler target temp 70C.

This must be a man without a wife

Tbh i still have not turned on my CH.
A jumper and a blanket does the job.

Even though you are not feeling cold, you still should put your CH once a week it helps your house.

That's 1.238kW per hour as I said it was 3.5 hours of burner on time

Well, I have a number now. 0.5C increase in 45 minutes from body heat and a computer running at 30w with monitor running at max 90w. Doors are closed. The kitchen is approx 4.5mx4.5m. After sealing air leak, it gained +2C from 16C to 18C from passive heating. The fridge probably adds a tiny amount of heat.
