Agile :With hindsight of using forum, I think you have summed it up quite well. The situation is probably more complex than I had naively hoped; I have asked for the installer to review the installation and am awaiting their response. The combined answers on the forum have been useful in my...

Simond - Sorry to annoy you. As the main problem occurs when outside temperature is very cold (eg 2c or less), I thought raising boiler temperature would best be done when cold returns to prove point. Thanks again you for initial response. Gasman77 - I accept that must be a possibility...

Gasman77 - The radiators get hot to touch quite quickly. Simon - I guess you might be right though odd that plumbers (we've had 3) don't seem to think that's the issue. Quite mild here at mo but will give it a go on next cold spell if nothing else materialises. Thanks for all the...

It's not a combi. There is no outside temperature sensor fitted. Yes it is 100-w. Do you think the max 68c necessarily indicates a problem?

Sorry the Honeywell are the radiator controls. The controlling Thermostat ia Sunvic (I had assumed it was a Honeywell until I looked for a model no). It is this Sunvic thermostat I adjust to temporarily knock off the boiler by reducing thermostat setting. Note however high I set the thermostat...

For D.Hailsham There is a Honeywell programmer/thermostat for the CH in the hallway. The radiators also have temperature controls. They appear to work correctly as you can manipulate the boiler by adjusting the thermostat. The Hot Water cylinder has it's own thermostat.

Thanks for those replies. Can I assume from those that you think the reason the rooms can't reach temperature is that 68c is not high enough (for whatever the reason).

This is driving me up the wall so I hope someone here can help. Had a new boiler, Veismann 100, put in during summer but it has underperformed since the central heating went on. It seems to take ages (eg 12 hrs) to reach required temp (21c) on mild winter days (8 or 9c outside) and gets...
