> I have been accepted for a heating grant …. need to decide by lunch time tomorrow. Is this a scam? Seriously: have you been procrastinating for months about a genuine grant, or did you get a surprisingly-genrous offer out of the blue that has to be agreed to within 24 hours, i.e. before you...

The survey doesn’t say “urgent” or anything similar, and I think it would if it actually were urgent. Put it high on the list of things to do when you do eventually have some cash. Maybe get a quote, so you know what you’re facing?

I guess the YouTube algorithm has been showing her videos of how heat pumps kill kittens, or something.

Swap the pipes around near the boiler. Yes. If they ask why, show them the connection diagrams for the old and new boilers. If they say “but it doesn’t matter, the valves are bidirectional”, tell them the rads are connected TBOE. If they still don’t get it, say “look do you want this easy job...

Volkera - left two pipes are return and flow, respectively. Baxi: leftmost pipe is flow, rightmost pipe is return. WRONG.

If the TADO contacts are rated 6A and they fail so frequently, I’d use a 30A relay. You should also consider whether the pump is on its way out. Maybe this will save the TADO, but then the pump will fail completely in 6 months time, and the replacement pump will not need it.

You can install it anywhere convenient, where you can intercept the necessary wires. I.e. the wires to the TADO receiver and the wires to the pump (and a mains supply).

I would not recommend that.

Anywhere that is convenient, where it will physically fit, and where it is safe to do so. In particular the relay in their photo has exposed (live) screw terminals, so that needs to be in an enclosure of some sort. Have they advised on a specific relay? What is the rating of its contacts?

Anyway…. I’ve just looked at your first post again and I see that the previous boiler was a Vokera. I do have a recollection of a post here about a new Vokera model where someone commented that “finally Vokera have got flow and return the same way around as all the other manufacturers”. I’ll see...

“Just change all the radiators” about the same price as swapping the flow and return pipes at the boiler????? This is a DIY forum. My advice would be, keep your interaction with “professionals” to the legal minimum and do it yourself. Then you don’t have to deal with this sort of bullshit, you...

Well, whatever the history, it is certainly wrong. Fix it by adjusting the pipework wherever is most convenient, likely at or near the boiler. Edited to add: “consistently at the lockshield” isn’t the issue, but “consistently at the bottom of the radiator” is what matters. Just for clarity.

Feel the pipes at the radiator. The one that get warm first is the flow. Of course you shouldn’t need to do this, but…….

BTW: which thermal camera do you have?
