One last question, for now anyhow. Would it be OK to run the flow/return to the UFH in 15mm. The pack is for coverage of 24m2 and the distance to the boiler will be a run of approx 8m.

Thanks spudkey. I've been stood in my extension and old kitchen wondering how I would be able to get new pipework and cable back to the boiler and then it all became obvious. I can run the pipework along the edge of the wall just below the ceiling and then box it in. This will also give me the...

Thanks for all the replies. It gets more complicated the more I read. I thought these single zone kits for extensions and conservortories were meant to make things simple. Can someone clarify a few things for me: I currently have a vaillant ecotec combi with rads. To install UFH in a new...

Hi, I want to install a single zone underfloor heating pack similar to this http://www.screwfix.com/prods/48974/Plumbing/Water-Underfloor-Heating/JG-Speedfit-Underfloor-Heating-Pack-of-30m I currently have a vaillant 360RF wireless programmable room thermostat to control my rads on the...

Looks like I will have to contact Vaillant technical department. They do a control box that is used to connect to a 2 port valve arrangement. http://www.vaillant.co.uk/installers/controls_-and-_diagnostics/Controls/produkt_vaillant/vrt-65.html This may be the way forward.

bengasman, do you have any experience of Vaillant boilers. One of the other reasons that I don't want a connection back to the boiler other than having to try and get a cable back their is that the boiler is currently operated from a Vaillant RF360 programmable room thermostat and I am unsure if...

Would something like this be suitable http://www.johnguest.com/part_spec.asp?s=UFHROOMPACK_S1 From what I understand you conect your flow/return to the manifold and this is then pumped around the UFH pipework. There is an external thermostat that controls the pump. It states that if the pump for...

After a bit more research it looks like you can just lay some plastic pipe in your screed and then connect it to your existing heating system with a product like this http://www.uk-plumbing.com/danfoss-randall-fhvr-return-temperature-controller-p-1105.html Unfortunatley for me its only for...

Yes, I understand that yoiu need an extra pump, manifold and thermostat. I was just hoping I could tap into the 22mm pipework to feed to the manifold. I only require a single zone so was hoping the pump would be controlled by some form of thermostat but the boiler would be controlled by my...

Hi, Does anyone know of a suitable product that can be used for wet underfloor heating for an extension with a floor area apporx 24m2. Ideally I would like it to act as an add on radiator on my existing system. I have access to 22mm pipework under my bathroom floor that can be used for...

Reading up on it it does look like its a matter of stapling the pipework to the insulation. I have a bit more of a technical question now: I have a Vaillant Ecotec plus 837 boiler. At present it is controlled with a Vaillant VRT360f wireless room stat. Reading the installation instructions...

Hi, Thanks for the reply. I'm not too worried about the heat output that much as there are also going to be normal radiators in the room. My main aim is to give some warmth to the tiles underfoot. I did consider electric underfloor heating but the installation cost is similar yet much more...

Is it a particulary difficult job then to lay the pipework?

Hi, Due to a change last minute change of flooring from wood to tiles we would like to install wet underfloor heating in a new extension. I have seen a kit that cover 24m2 which would seems ideal...

Hi, I am considering tiling my new extension along with the existing hallway, kitchen and dining room. The total area will be approx 56m2. The flooring in the new extension is block and beam but has 100mm insulation so I'm hoping will be fairly warm. The rest of the house is also block and...

Hi, Are there any issues I should be aware of when fitting the top of a UPVC window frame to a catnic lintel. The lintel is in a single storey extension so there is no brickwork above the lintel it is boxed in with soffit and facia. I am going to screw the frame on the sides with frame...

Would the benefit of that be to simply protect the pipe from any potential damage.

Hi, Is it OK to run 15mm pipe behind dot and dab plasterboard. I am having new radiators fitted in an extension and the easiest and neatest way to route the pipe is down the wall and then dot and dab with plasterboad. It will be a straight drop to the radiator so should be easily identifiable...

Hi, If a crimp connection is used on 1mm lighting cable must the crimp be inside some form of protective plastic box. Thanks

Thanks for the reply, I take it just normal expandable foam would be OK with frame fixings used on the other three sides ?
