    No, I contact the manufacturer and they emailed me a diagram

    Radiator union change from 3/4 to 1/2 puzzle

    Oh, I've also created a radiator size calculator if you know how many watts you need, you can change the flow temps etc and it sizes the rads. Will post on a different thread some day!

    Radiator union change from 3/4 to 1/2 puzzle

    Interesting that a thread on valves stimulates as much convo on running boilers cooler - I like it. I've done a comprehensive heat loss calc for every room, then come up with a realistic plan for insulation and re ran the calls. I've just finished insulating under my living room floor with wood...

    Repair gap between wood paneling

    There's only a couple of bits that need attention really, most of it can remain higgldy piggldy. I did buy the correct profile round over bit for my router, so could recreate the magic with MDF. But I'll be staying in this house for a couple of decades and will be pleased with my restoration...

    Thanks, I've bought some tails on eBay, hoping I'll have a bit luck...

    Repair gap between wood paneling

    Thanks all! I certainly won't be burning them. I've already stripped them to bare wood before priming; the quality of wood used 140 years ago is quite something. I'll have a shot with the caulk which was my preferred option because of the flex, I imagine despite the tight grain that the wood...

    Radiator union change from 3/4 to 1/2 puzzle

    Thanks! I've had the tails out and they are indeed 3/4 inch - rare, but true. I'm swapping older panel radiators with type 22s sized to allow me to run the boiler at 50 degrees, will help fight the cost of living crisis! I'll have a look for 1/2 union tails, but fear they still wouldn't mate...

    Repair gap between wood paneling

    Hi team, I've unearthed some original tongue and groove wood paneling in my bathroom. After stripping old tile adhesive, sanding and priming, I'm now needing to repair them before more priming and a top coat. I'd like some advice on how you think I should repair gaps between the boards. I was...

    Radiator union change from 3/4 to 1/2 puzzle

    Well... I have some 'traditional' style trv valves on my rads which I fitted last year. The rads had a 3/4 inch inlet, and it took me a long time to find valves that had a 3/4 inch fitting (there are 3 linked rads on a bay window, hence why they were 3/4). It's a union joint between the rad tail...

    Vaillant ecotec hw circulation pump

    You assumed correct, the Wilo pump has a check valve built in - nifty bit of kit (if not a bit expensive!).

    Should i replace old copper pipes?

    The 35mm is actually inch and a quarter and is already there, so it's more a question if it's worth replacing. More volume would suit a heat pump down the road, and running at 50 degrees, you need bigger pipes than running at 70. So I'll need 28mm based on calcs. The actual boiler is 46kw which...

    Should i replace old copper pipes?

    It's a 46kw vaillant - certainly oversized. The house is 300sqm Victorian. I'm going room by room, insulating as I go. Once I'm done I'll need 18kw of heating, assuming I can insulate as much as I hope. I've also calculated correct size rad for each room based on heat requirements, and then what...

    To see what others think?

    Should i replace old copper pipes?

    Yip, pretty much! Needs 25kw of heat, so 3 times the norm!
