How long does your central heating take to heat the house?

UPDATE: Thanks for all the information. Last night, the temp outside was a reported 0 degrees but the temp inside only dropped to 16. I also reduced the flow temperature down to 75 degrees yesterday. The heating company left it at full 88 degrees saying that the stat will run it at the heat it needs.  Heating came on at 5:30 with thermostat set to 23 degrees and heated as below
05:30 16.0 degrees
06:30 19.0 degrees
07:00 19.5 degrees
07:45 20 degrees
08:10 20.5 degrees
08:50 21.0 degrees
Take on board what macman is saying. The stat was only set to 23 degrees as we are trying to see how quick it warms up and whether it can reach a higher temperature. We will not be running the heating at 21 degrees going forward; it's warm enough on 19 to 20. The system was only installed a couple of weeks ago and we are just trying to check it is all ok and heats up as it should. The reason for this is we have found that the radiators installed in the bathroom and downstairs toilet do not heat the rooms. If we leave the bathroom door open then it draws heat from the landing and the room heats up, hence why we started to think the radiator might be too small. We checked the radiator manufacturers website and their calculator suggests a much bigger radiator than that recommended and installed. It also states that a couple of the other radiators in the main living rooms are also slightly smaller than they recommend so we just wanted to be sure that it is working correctly. Also, when we turn the stat up, the temperature does not seem to rise beyond 22 (not that we would need this). Thanks again for all the useful information.

As mentioned in my 1920s, solid wall, 3 bed detached, I currently have the thermostat set with a minimum temp of 14C overnight, then 18C from 07:00 to 09:00, I manually keep it at 18C for the rest of the day now I'm at home, then 19C from 18:00 to 23:00. With that it's comfortable for me, I can't sleep if it's too warm hence the 14C minimum. Last night I think the outside temp supposedly dropped to around -4C around here and by the time it hit 9am the thermostat was still only reading 16.5C.

BTW, what are you using to log your temperature readings?

Maybe this has already been asked... Where is the thermostat?  Is it in the hallway or a room?

Are the radiators in the bathroom and downstairs toilet conventional radiators or heated towel rail style?  Towel rail style don't produce anything like the same heat output as a conventional radiator of the same size.
