Why is it better to have the whole system running open without zoning? Why would it be better to heat parts of the house that aren't being used? Or to heat the whole house to the same temp?
Its possible there is a blockage but I don't think so as the flow and return temps seem fine.
When the system gets serviced I'll ask if they can flush it.
Well this could be part of the problem. There is definitely air in the flow meter of the new loop. Engineers have been out to bleed the system and got lots of air out. Maybe there is still air in the new loop. The UFH is booked for a service and full system flush in a couple of weeks, so I hope...
In The rest of the house there is either a single or double loop per room, each with its own thermostat and controller (heatmiser). There's a manifold on the ground and first floor. Both fed from the same buffer tank, heated by the ASHP.
Now I think about it, the ground floor rooms do have snail...
The shower room is in an extension.
I think you're right, the problem is likely to be because there isn't enough insulation below the screed, and also I think the screed is too thick or rather the pipes are too far away from the tiles.
So now it's a case of ripping it all out again or living...
According to www.speedtest.net our 4G connection has an idle latency of 20 -50, but the download latency and upload latency is much higher (>200). It looks pretty similar with starlink.
I did some research before ordering the kit. The 30 day trial is also part of that research. Posting on here to see what others' experiences of using starlink is also part of that research.
This is the spec from the starlink website but it is general, not specific to sites.
A couple of people...
@Wizzkidy @LostCorpse , i probably should have said this is for our home internet connection rather than for a connection when out-and-about.
I wasn't really expecting anything, i knew the download would be much faster than our 4G connection but i hoped the upload would also be faster. I wanted...
flow and return temps feel the same as other loops, and also hard to say whether there is difference on the flow and return. I'm planning on getting a laser temp sensor or thermal camera to take some surface measurements.
I've set up the starlink and run some tests.
Download speed is great 80 - 200
Upload speed is not great 8 - 20

With our 4G setup we usually get

We've used the same loop pattern in the rest of the house and it works fine. For such a short run of pipe i wouldn't have thought the loop pattern would make much difference, the flow and return temp doesn't feel all that different. The pipes are sitting in 70-80 mm of screed, so there is lots...
We've tried that. The thermostat head has been off all day today and still the tiles are still only just getting warm in the areas marked in red on the above photo.
Manifold - the new loop is the first one on the left. The one with the nice clean flow setter!
Short pipe run from manifold through first door, then to next doorway of the bathroom.

Dropped a tin of paint onto a tiled floor which is not grouted yet. The tin popped open and spilled white paint everywhere, especially into the gaps between the tiles. Doh!
