    Dear John (right or wrong?)

    I did write-up that msg but I agree with chuck What I actually sent was "Sorry but I'm unable to help with this" & when he chased me I replied again with: "I am familiar with the system. I believe I quoted to replace it in 2021. Unfortunately I'm unable to help any further." (He's a landlord and...

    viessmann 050-w and viessmann generally

    Over-hyped! Manufacturers have been hyping online control and WiFi with little emphasis on weather comp. The only 'hype' I see is from old guys like me and other experienced engineers. Domestic market is probably 30 years behind commercial with regards to weather comp - its hardly a new fad! I...

    Dear John (right or wrong?)

    I had a customer a couple of years ago that had a quote for a whole new system. He was upfront about maybe not doing it for a while but after 2 years of preferential treatment (Out of hours calls, and a spot of leniency on some bills). He decided to get someone else in because I was on holiday...

    Rad heating up while off

    I did some plumbing for an old lady who's children were trying to force her to get central heating fitted. She refused as she was happy with her open fire and bed warmer. I bet she saved a fortune too!

    Dear John (right or wrong?)

    "Hi Mr *****, thankyou for your enquiry but unfortunately I am not able to help any further. I believe you've found my last five quotes unacceptable and as I quoted to replace the item that is currently faulty in 2021, I can only assume that it will still need replacing. Quotes are...

    viessmann 050-w and viessmann generally

    I would like to think that vaillant controls would be more effective and I'm a big fan of matching boiler and controller (except baxi) If 'main' is running with opentherm then there probably won't be much difference and if in a cupboard then looks don't matter. The smart choice would probably be...

    viessmann 050-w and viessmann generally

    Sorry I didn't see this yesterday. Either would be fine. The most important thing is that your happy and confident with the installer. For me the decision would depend on the control options. The vaillant is more capable but only makes sense if those capabilities are being implemented with the...

    venting question - using old empty outdoor SVP as air vent

    I can't see why it would be a problem, it's a bit unusual to say the least. Durgo wouldn't need to go as high as the loft, it just needs to be a set height above highest overflow level?

    Bi Flow dual taps query

    Just have whatever you want... Strictly speaking a mono-flow tap should be fitted with non return valves tho I believe. Are there any regs on this?

    Mixer shower recommendations (mid range)?

    I struggle now that the retailers 'brand' the brass wear. It used to mean something now its just a ploy to make them fit in with the proper brands so uninformed consumers cant tell. If they have a company website on page 1, glossy looking brochures/pdf's with schematics then they're proper -...

    Replacing Thermostatic cartridge -temp control housing stuck

    Thanks & Well done persisting. I know the feeling when your pulling on something and wondering if there's a grub screw or something you've missed. The main body actually looks OK.

    Outside sensor slope vs room temperature setpoint

    You need an R8810 bridge. Don't forget opentherm was developed by Honeywell.

    Outside sensor slope vs room temperature setpoint

    This isn't very clear and it could work in various ways. Worcester has weather comp and 'room influence' which boosts flow temps when re-heating. I would expect opentherm controls to work similarly but opentherm is just a protocol and manufacturers don't seem to advertise the specifics of how...

    New central heating - what should I be asking for?

    Also for arguments sake- Just a straight swap for a regular condensing boiler would prob give you 90% of what you want and leave you plenty of time and money to invest in a whole new renewable system when the time comes. Renewable installers have the niche things down and your little regular...
