Underfloor heating

The flow of water is managed and controlled by manifolds. A control pack is used consisting of a pump, a thermostatic valve, a zone valve and an isolating valve. This ensures an even lower temperature.
A condensing boiler would be far more efficient. However a conventional boiler may be used.

Please don't shout at me I wanted to have a go. And I only did because its you dev

 

much like God almichty, thermo valves work in mysterious ways.

 

The water tempy will vary between say 35 oC and 60oC depending on the hoosie.
With thermy valves use 43oC for screeded floors and 55oC for timber suspended and floating floors.
But this still does not answer the question does it
I have to go to the dentist now but I will try again later

 

Oh yes, tis a mixing valve
There is an "S" plan for instance where two port valves are installed to give each manifold circuit independence.

 

A wet ufh system uses the boilers return flow (water returning to the boiler after going round the system). A sensor on the manifold detects the temperature drop and automatically adds water from the boiler flow (water that has just been heated). This ensures the correct temperature I think.

 

I don't know dev I think I might have bitten off more than I can chew

 

UFH is more efficent up to 25% & around 25% cheaper to run than radiators, & start using a heat pump you nearly double the running cost savings to about 45%.
Heat pumps up to around 400% efficiency,water is at 45oC sometimes lower & far superior to a combi boiler.
Sadly,we do not not take advantage of the heat pump technology or,uhf, it's is something that should be used more in this country

Using a pumped screed give the best heat transfer,as it fills every void, something you can rarely achieve with a traditional sand/cement sceed.Also it helps to have good insulation under the screed, concrete.

Therefore a pumped screed becomes a better thermal heat store, (like a giant storage heater)
With radiators you need to have the water at a higher temperature to compensate for heat loss in the pipework,etc, something that isn't a issue for uhf.

 

I had a good go though dev not bad for a girly

I'm sure kiab will be along soon to give the correct answer peeps

 

As if by magic that's uncanny

 

ufh blending valve or mixing valve.

I am a great supporter of uhf & heat pumps-( air & ground versions) they are so under use here, but don't forget the Romans invented underfloor heating system ,over 2000 years ago with their hypocaustum,or hypocaust, but when the Roman civilisation died out in Britain, so did ufh

 

Aye, they were very clever people them romans! They knew a thing or two.
But I feel it only fair we point out to peeps the few downfalls kiab.
Leaks ooooh nightmare if you get one
At the risk of repeating oneself my ex was a plumber
There were many late nights due to leaks or maybe he lied

 

Leaks shouldn't happen with uhf,IF installed correctly, pressurised the system,& if the gauge drops, then there a leak.
I've seen idiots snick a uhf pipe with a trowel when laiding a sand/cement screed more than once over the years, that's the great advantage with a pumped screed you eliminate that problem.

 

Exactly corr my ex could tell you a tale or two!!!
This pumped screed sounds marvelous though
No flowers today then strictly business I see

 

Just for you.

 

Haha! Thank you you spoil me!
