I just meant supply and fit of the supply and returns not the ufh loop. I didnt realise a plan or drawing was needed to route these 2 pipes thinking you'd just take them straight to where they need to go but sounds like @Mulberry View has to run through the floor?

What do you mean route the supply and returns? As in physically put them in? Is it the same person doing heat loss and ufh layout?

What kind of fee do these heat loss consultants charge? Do they also do the ufh layout?

He doesn't want flat ceilings!

I'd of loved to have met the man. What a great experience!

Would you not prefer a 4" floor drain? I used one once fits straight inside 4"pipe. But yeh wouldn't need a vent.

I dont think anyone looking at a house in future would be put off with a2a. So should suit op?

It must be volume production economics. I remember people saying how simple mvhr units are inside.

What did you pay for your bare units? What do they rrp for?

How much is a mvhr unit alone to service 150m2 vs a boiler to do the same? What would a boiler be 1000 or less?

It does sound like a bells and whistles job. I dare say the house is worth over a million quid though pretty high spec. Mine will deffo be diy, last one was. I won't be having the plaster in vents.

I also want dry autumn. I want to get a backhoe in to clear our site after a planning decision. Scheduled October atm

Crazy my place will be half the size i wasn't hoping to spend near 5k on mvhr. How are these things dearer than boilers

I don't think they are I've built without them in past. Once i got asked to put them in because of potential methane.

I'd take it with a grain of salt. By all means do what you need to get the site sorted before it gets too bad but don't panic.
