Help on pipework from boiler to manifold.

[king of pipes]

This will give you a idea of how it should connected your primary flow and return pipework needs swapping over . Kop

Then yes the connections are wrong

2 hour job max

Thank you for your reply. It's in line with what the other plumber said to. I'm devastated as I paid over £1000 for the connection and correcting it is gonna cost me £900.

Those prices are shall we say ambitious to say the least!
As Shaun has said max 2hrs to sort out.
Unfortunately poorly installed underfloor systems seems to be a trend we are polypipe registered installers and I get 2 to 3 calls a week to sort out poor installations.

Can I ask does the UFH heating even heat the room? Looking at how it’s piped I imagine the valve is fully open to take hot boiler flow which is actually your UFH return. If this is true then the water in the UFH loops is just recirculating itself and the water from boiler is just flowing through the by pass?

It all works. We have warm floor. And thats is what I don't understand? We were told that the pipes should be swapped, as seen on attached picture. Is that right? Another question- if it works should I leave it as it is or the whole system is less efficient and I might pay more for energy, or the boiler/manifold/pump might have less life span?

Green is a bypass as you have pump overrun on the boiler

The red box with green arrow is the by pass. When the blending valve is almost throttled shut the by pass opens to create a circuit for flow. Without by passes in certain scenarios you would be pumping against a closed circuit (dead heading).
The pipes should be repositioned yes to ensure proper function.
You say the floor is warm but does the room actually reach target temperature at the thermostat?

Yes it does reach the target temperature on the thermostat.

We were told that it will be a whole day job. Because the plumber would have to run all new copper pipes from boiler to manifold. Could you explain what exactly would need to be done to not to incur in such big costs. Thank you.

It's not a big job couple of hours tops, drain down and swap the flow and return pipes over. Kop
