Well, the orange should go live when valve opens as here http://wiki.diyfaq.org.uk/index.php?title=Image:2PortMoMoValve.gif Sounds like a really daft way of overcomplicating things.

Sounds like it's a mo-mo valve - so it needs power to open, then also power on another terminal to close. No spring loading?? So the cylinder stat needs 2 wires to the valve, from terminals 1 and 2. If you've got a mo-mo valve, timer sends power to top stat - C. If stat needs heat, it sends...

As above, I wouldn't buy a kitchen without physically seeing at least one carcass. You can get much better deals elsewhere tbh - Crown Imperial are good. That's who we're going to use, having looked at everyone from Vance's Kitchens from Hell all the way up to Siematic. Ignore 50% off sales...

Phone insurance co and ask? Seriously though, when the velux was fitted, ideally the rafters (either side of the ones chopped out to make a velux-sized hole) should have been doubled up or braced. If they haven't, they're holding up double the amount of tiles they were deisgned to support...

Oh, and does the ufh have it's own wiring centre ie signal out to pump/boiler? Each roomstat should go back to the wiring centre, then a relay drops to turn the pump on and draw from the store. The boiler should be completely separate, controlled by the cylinder stat(s). All assuming it is a TS :D

Are you sure the two stats are one each for htg and hot water? Does sound like you have a thermal store - we've got one, which I wired myself with twin stats to make the boiler work harder and less often. S'pose it could have a lower stat for htg/boiler, then the higher stat for hot water maybe...

No idea if that meets regs or not, but sound like a very good idea. Pottering on with our extension, and it will have a screeded floor, with pipes feeding a wc/sink/shower. Are there any downsides to plastic pipe sleeved in more plastic pipe? Other than the whole 'plastic pipe and fittings are...

If you want the water to drain away from the house, and still have 150mm between blocks and dpc, you'll either have to raise the house or lower the pavement. Neither is practical. Correct way would be to install drain channels within the paving, possibly around the perimeter of the house, tied...

I wouldn't just leave it - chopping over a third out of the joists because it's the easiest way to run the waste is dangerous - are you having a bath in your bathroom, filled with water? I did the wastes in our bathroom, and following the regs on notching meant using about 10 metres of 40mm...

I 'think' the fixing is like a plasterboard rawlplug thing - you get the threaded bars screwed onto the steel frame, set the black plastic bits to roughly the right 'depth' from the tile backing board. Push wc pan onto wall, hear a click from both black bits as they grip the pan... ..then...

Ebay - any Warmfront/council/keep-the-poor-warm-scheme fitter will have loads in his garage.

Been doing exactly this today. Fix the frame and cistern etc etc, board over and cut hole with 5mm clearance so the concertine bit protrudes through the board, allowing 10-15mm for tiles, tile, and once all that's done, if you've set everything right the concertina bit should line up with the...

Ah, the Megalow moosoon. :taps side of nose knowingly: Perfect for bungalows due to it's reduced height, but an absolute cow to fit.

That, right there, is the future. Complete overkill for a 3 bed semi, but it'd save a fortune in a big house. Being able to weather-comp or control hot water and 2 different circuits independently, even one with weather comp and the other purely by roomstat is perfect for space heating both...

If the shower is as flat as a fart the dynamic pressure is dropping either because your shower is just too high-flow and german for a UK-spec 3 bar megaflo with a prv on it, or because something somewhere is faulty/blocked - your stoptap is wide open isn't it? Gauges as recommended above will...

That looks seriously tidy! I have a store/buffer, mainly because eventually we'll have solar, wood and gas, and I have gradually collected bits from ebay to add weather compensation to my rad circuit - a kanmor up36 controller and a honeywell 3 port rotary valve as in the pic. I've got lucky...

There you go - someone experienced with the right knowledge of oil boilers. Just proves my point - without the right plumber, it's an uphill struggle.

I think (as a non-plumber) you and John are right – the boiler can’t transfer the heat well enough via an indirect coil so its cycling on and off as the return is too hot – direct connection would be best – flow into the top of the tank, return from the bottom, mixed to suit the boiler. The...

Labour screwups? Off the top of my head.. Deregulating the banks so that building societies can go gamble with the big boys. Selling gold cheap, and flat out lying stating the Bank of England supported the sale. They didn't, they opposed it. Brown lied. Allowing europe to govern us - 72% of...

If the polls are to be believed, either Labour or Conservatives will win. Third option is a hung parliament - which will mean nothing gets done except arguing. People really need to get a grip and vote based on policy not cheesy smiles or what dresses the politicians wife wears. Have a read of...
