    Worcester Bosch or Vaillant?

    Hi sooey, You are entitled to your opinion but it would have been more appropriate to specify which of my comments is incorrect. I am, with difficulty, refraining from descending to your level of slobbery.

    Worcester Bosch or Vaillant?

    Worcester Bosch are the market leaders if you want maximum domestic hot water. Their main weakness, in common with virtually all other makes - including Ideal and Vaillant) is the use of aluminium as a primary heat exchanger which gets exceedingly hot. Worcester are dearer but not by much...

    underfloor heating problems

    Hi Flowboy Thank you kind sir. I've made a note on my CV should come in useful some time (I've just had my 78th birthday!!) A couple of points. I covered the way to remove the flowmeter glasses but just screw down each meter using a spanner carefully on the nut and then unscrew the...

    Hi, Although there is no mention of a check valve in the Worcester manuals, I have just confirmed with Worcester Technical Dept. that there IS a check valve incorporated in the right hand side of the Integral Charging Link. The technical guy did not know this offhand and had to get a...

    underfloor heating problems

    No return valve on combi

    Hi, Sounds like it, but why they call it "Integral" when it is not supplied with the boiler, beats me. Look at where you insert the key to top up and it is probably an isolation valve at the end of a flexible pipe. That valve may contain the non return element; if so it will be much longer...

    underfloor heating problems

    Hi Looking at your manifold photo again there appears to be something missing.The end of each manifold chamber should be connected to something, either the flow or return pipe from the heating source via isolation valves or an automatic air bleed valve - or were there no isolation valves and...

    underfloor heating problems

    Hi, I forgot to say that the flow meter adjusting nuts are set a fully open but I notice that the flushing pipes are still attached. I assume that you have reset them by now.

    underfloor heating problems

    Hi, Excellent photos! One picture saves a thousand words! They are standard flow gauges. To remove the glasses, grip them tightly by hand - possibly using a rough cloth to increase grip - and unscrew them in the normal anti clockwise direction. The system looks normal (apart from the...
