I might be moving & will need UFH in an extension. My sister has an electric system in her kitchen that costs the earth so as I’m a miser id rather go with a wet system. I’m going to research it but any views or advice please?
Cheers all

Depending on the area, the UFH in an extension is best treated as another CH Zone, from both a mechanical & controls point of view.
The floor construction has a big bearing on the system you select to install, but most floor constructions are suitable. However, a concrete floor is the best option, with the thicker the concrete(thermal mass) the more heat is retained & a lower running temperature is possible.
As for the installation, a piece of piss really.

Cheers. Any makes that are good?
I just saw in screwfix that JG do a system.
Thx

There's never been a big demand in Wigan for UFH because of the cost of installation, We're tighter than bull fighters britches when it come to spending big sums on something that can't be seen, We like to see something big and shiney for our money,  |

They supply all the gear & a drawing detailing the pipe layout etc. Here’s one, but shop around; www.ufhtradedirect.co.uk/It’s generally more expensive doing it through a Pkumbers’ Metchant. |

That’s a lot cheaper than screwfix. Thx for that. The next question the. Is about zoning. So if I have hot water & ch then no problems with an s plan & controls. But if I then want to put the UFH on a different zone how does that work? Do I have a separate timer? Or are there timers that can deal with this? I’m thinking of a new heating system with an unvented & UFH in an extension that I want to control separately to the other heating. Cheers |

The UFH has its own 2 port valve, this would be controlled by the control unit for the UFH or a simple programmable room thermostat.
It depends on the size of your UFH system, you may want to control individual rooms in the extension for example, so in that case you sub-divide the controls to bring On/Off individual loops at the manifold.

Ok that’s what was confusing me. So the ch/hw stay on their own programmer & the ufh has its own programmer. It’s all clear Cheers |

Have done a lot of ufh in my time and I’ll offer one massive piece of advice. Choose a manufacturer and get them to spec the plans and area. It’s all on them then. I used to use wavin....they were really good. They also allocate the cheapest supplier to you.
very easy to control dicky is bang on. Separate stat and control for the ufh on an s plan plus.

So unless I've not understood something does that mean the customer has to control his ufh seperately to the rest of house? So if for example he puts it in a new 1st floor extension and adds ufh to there only, then to change the heating for the whole house he has to go to two controllers?
Starting not to sound like central heating anymore ?
Couldn't one programmer control all three zones? (i.e. MVs on hot water, original CH and new UFH ). Or have I got it all wrong?

Not much call for UFH up here but I have seen this used for a four zone install and it worked well and it's still central. www.heatmisershop.co.uk/heatmiser-tm4-ts-230v-4-channel-timeclock/?gclid=EAIaIQobChMI1uil3Mjk4QIV6rDtCh3Jeg3WEAQYCiABEgIl1PD_BwE |

The UFH is controlled separately time & temperature. Simple On/Off controls are most common, so the UFH has a ‘Set Back’ temperature, just to keep it ticking over or during the night for example. |

UF heating is the way forward! It gives off such a nice warm heat! It's lush!  |

UF heating is the way forward! It gives off such a nice warm heat! It's lush! It’s amazing mate, mainly Radiant Heat & 19degreeC feels like 21/22. I did my first system in 88, baby steps. The Architect, Home Owner etc were amazed by it. Did loads over the years in rural areas of Scotland back then. Now it’s used everywhere. |

Good price too. I’d prefer one programmer but I’ll have separate if needed. |
