Not the best day for this to happen.

Check the system pressure and top up if necessary - but after that the best advice is to get the people who fitted it for you to come out and sort it - These Worcester combis usually have a 5 year parts warranty and with a boiler that's just a few weeks old, you oughyt to be able to get the labour for nothing as well. It would be a shame to throw those benefits away by tinkering yourself.

    Note added much later for any subsequent readers:



    Since writing the first solution, I've had this problem myself and had a chance to experiment.



    These sympoms (sounds like the Tardis for a short while, then locks out with an EA code - on the coldest day of the year) is most likely to be the plastic pipe that carries condensate from the boiler into the waste water system having frozen up.



    This can be a problem in installations here the condensate drain has a long run on the outside of the building.



    The official solution is to thaw the pipe out with a hairdryer if you can reach it, and to wait for warmer weather to arrive if you can't.



    The unofficial solution (and in no way recommended) is to disconnect the waste pipe as close to the boiler as you can - and let the nice warm acid water run down the outside of the building for a day or two. If you do this, you need to make sure it isn't going to land on anybody and remember to reconnect when the weather turns.



    In the long term, it's worth improving the lagging round this pipe so you don't get the problem next winter.

New Vaillant 360 eco plus boiler, takes almost 3/4s an hour for rads to come up to a decent temp. Hot water is fine. Called out install Engineer who is an excellent tradesman but he says everything


We have just had our old system boiler replaced with a vaillant ecotec plus 837 and sounds like a similar working operation to ours. At first I was a little concerned,but I was told by our installer that he was told by vaillant that these very latest boilers size the system on start up for about 10 mins, then take temperature to target flow which you set boiler at. So even by setting target flow temperature very high you still get the initial sizing cycle, which ours was about 30-35c temp. These boilers seem to run biased for efficiency as after a while they modulate the boiler burner down and the radiators run more on the side of warm than really hot like the old type boilers. You also get better efficiency as at lower temperature the boiler condenses better. You will also find you get a more constant temperature in your home rather than over shoots. I was concerned at first, shame there was no info/explanation in user manual as people do need to know that this is normal operation. We are used to ours now, took a month and by the way these boilers can make a creaking noise but was told this normal expansion/ contraction but annoying when sited in bedroom cupboard. Best of luck!
