Underfloor/boiler set up.

[southcoastboile]

I've installed nuheat underfloor through my house. It doesn't seem great in that you can feel were the pipes are so you get hot and cold lines across the floor surface. That said I haven't had it on for more than about 8 hours but I would have thought this would be enough to warm the whole floor?

The other question is the boiler does a small circuit about 6 meters in total. This just does a loop and the underfloor manifold comes off of that loop.

I have set set the boiler stay at about 60 degrees. The design flow temp is 55 at the flow manifold.

i have got a Glowworm combo and wondering if it has as delay on it so it's not cutting in and out a lot on such a small circuit and if it has would it be worth setting up?

finally, when I replace the boiler does anyone know of a boiler that works well with underfloor or is it all the same? Just thinking some boilers might have an underfloor set up that means it modulates better on a small circuit or something?

Thanks !

Underfloor needs to be on 24 hrs a day. Should be used with a programmable stat to do night set back.

Can you describe exactly how you have installed it.

I disagree with that chalked, I've installed quite a lot of ufh in new builds houses, extensions and existing houses. I've found that room temps can lift within a few hours to a comfortable 21degrees.

Thanks for the replies. The flow is run up into the loft and back to the boiler as a loop.

Off this loop is a pump set up with a temperature reducing valve.

After the pump and temp red valve there is another flow and return which go down Directly below the boiler to feed an underfloor manifold which feeds the kitchen and lounge.
The flow and return after the pump also run across the loft for about 5 meters before dropping down to a second manifold that feeds the rest of the house.
It's hard to explain. I don't know if that makes sense?
I can put some pictures up of the design of not

what design have you installed the under floor in ? loop wise

Yes put a diagram up, your description in quite confusing
