have you bled the radiators? might be something as simple as that.

Do you mean water rather than weather for the lukewarm.. Have you checked your pressure you might need to turn the taps on at the bottom of the boiler to fill it up... as the pressure might be low..

Obviously the water coming into your boiler in this weather is a lot colder. Sometimes if you have a fairly high level of pressure from your mains, certain combi's cannot heat it up quick enough. This is why you will find it cooler than it is in the summer. Instead of opening your tap full bore, try opening it just enough to make your boiler kick in. Then see if the water is hotter.

Bet it is, bet ya, bet ya

If not there is a water temp dial on your boiler, crank it up a bit

opps, yes meant cold water not weather - brain going faster than my fingers - will try bleeding but thought thats only for when the pressure is too high

the water temp dial is on highest

Happened last year too but definately getting colder

Not bad huh? See us brain surgeons can turn our hands to other things as well

try what i said then with the tap. I take it you are referring to water temp and not central heating temp?

The water pressure shown on the boiler us for the radiator circuit and should be set at a working pressure of about 1 1/2 bar this does not affect your domestic hot water . As a combo is a heat on demand boiler it heats the water as it passes through the heat exchanger but in this cold weather the water entering the boiler is far colder so the boiler is working harder so just as Ryan says dint turn the taps in fully thus keeps the water in the boiler longer

allowing It to heat it up to the required temperature

That would be my guess. You can tell if you look at the gauge at it's reading less than one bar.

Apart from the obvious, ie turning up the water temp dial on the boiler and as has been suggested, throttling the tap back to achieve a reduced flow during times when the incoming water supply is extremely cold, you could have a faulty heat exchanger or diverter valve in the boiler itself. The pressure gauge only relates to the pressure of central heating system and has no bearing on the domestic hot water temperature. Another cause of the problem can be crossflow of water, ie the internal leakage of cold water within the internal structure of a mixer tap or mixer shower, causing the resultant temperature of the water 'out the spout' being less than it should be
