    Vaillant VRC 470F how difficult to install?

    I talked with the engineer again and he says that what needs to be wire is not the weather compensator but the eBus to HW. I have a quite old vented system and boiler is replaced by a system boiler + unvented. Any thoughts?

    Vaillant VRC 470F how difficult to install?

    I am replacing my boiler and I want also to update the controller to the VRC 470F. Would this require more work for the engenier than installing any other controller? The engineer is telling me they need to run some wires but what I understand from the manual is that is quite straight forward...

    System or heat only boiler

    I think these questions also aply for Intergas. Anyway as said I think a bit pointless to try to save a few pounds on the boiler when that is not the biguest costs. I will go with Valliant or Worcester. On heat only boilers which one would you recommend.

    System or heat only boiler

    The price is the boiler is less than a third of the quote so saving a bit on the boiler won't make a huge difference. To be fair I prefer a longer warranty.

    What's your view about Valliant? I wante to fit a weather compensator and I am not very keen on Worcester one.

    System or heat only boiler

    Yes currently the system is open vented. No expansion vessel. The idea is to have it unvented. Underfloor heating is about 10/15 years old so I do not know if this can be considered really old. I read cement can corrode the pipes but I have checked now and all pipes enter in the floor...

    System or heat only boiler

    Many thanks! What they say is that with the heat only pressure can be 0.5 bar but with the system it will be 1.5 and if it drops below 1 it switches off.

    System or heat only boiler

    I have a quite old (about 20 years) boiler that needs replacement. I had a few quotes with similar specs and prices. All of them were with a system boiler and a megaflo. My house is about 30 years old with good build quality. 15 years ago a big conservatory was build with underfloor heating...

    Solid construction wall over chipboard

    Thanks again, the only reason I can think about is that this is a partition wall without a wall beneath, on the ground floor. This wall extends to one bedroom wall that has a wall below. Maybe this provides the stability to this section on the wall. I will lift the chipboards during the...

    Solid construction wall over chipboard

    Hi pinenot, thanks for your reply. I know I was not very detailed but actually the wall sits literally on top of the chipboard. I do not have a photo of the joint between the wall and the floorboard but in the video below you can see what I saw when i lifted a damaged piece of chipboard...

    Solid construction wall over chipboard

    Hi there, I bought a 30 years old house a few months ago. The landing upstairs was very creaky and about 2 months ago I had someone to nail the chipboards. This improved for a while but we went on holidays for 3 weeks leaving the heating low and I think this caused that they are creaky...

    Curved doors

    yes the back room is a bathroom and has a window but obviously I do not know how well it was ventilated. Furthermore the issue happen in other doors like bedrooms where this should be a less issue. Regarding the second picture, it is true but I think that is mainly because it is curved...
