From the Installation and Maintenance Instructions, 1-C2 enables you at least to see the current pump output as a percentage of the the rated output. This is a bit ambiguous - I assumed it can be changed from 100% otherwise why is it there?

Having been running the boiler for a bit, I now have an analogue thermometer thermally attached to the return pipe. It seems (in these cold days where the boiler is working hard) that the return temperature is always about 20C below the flow temp. As this isn't being done by the pump varying...

They are more expensive than dumb pumps, difficult to fit post-installation, will violate any warranty, and make maintenance difficult. IMHO a variable speed pump controlled to match eg max(flow temp-20, 45) or with some profile designed according to the boiler and installation characteristics...

Yeah - It was Soonack cancelling the top end of HS2 I'm afraid so we can all look stupid. So like everything else, news is late arriving in the north now. Actually I've just subscribed and I've seen thermal paste suggested on comments for thermometers and thermistors etc before that had...

We've just had a new combi installed - a budget version Worcester Bosch Greenstar 1000 30kW. This replaced an old Baxi 105E 31kW that was falling apart. The WB unit is a nice boiler overall - the DHW arrives almost instantly - but I am disappointed to find it doesn't report the return...

Try some heat sink thermal paste and scrub the pipe and thermometer, as used in computers. Only a few quid online.
