I have hardwood window frames previously stained with sikkens, but the last owner put an even darker stain outside which now looks awful. We want to brighten it up with a lighter colour like off white or cream, so need an opaque product. Local decorator shop tells me "JOTUN DEMIDEKK ULTIMATE"...

2nd question first. Yes, I wired the the pump directly to boiler and wired the zone valve dry contacts to the so called room stat terminals 3/4 removing the link. I carried out a heat loss calc prior to purchase/specifying boiler size. I'm happy with that aspect. I did not purchase a vr65...

Does a flashing radiator symbol flash on the display after the pump goes off? Yes it does, and I cant find out the signifcance of the flashing symbol, can you enlighten me

Thanks for input, clearly the ABV is faulty. Your second point confirms is is normal for the pump to operate against closed valves, as the ABV will ensure minimum flow is maintained. My last unresolved query is why does the the pump shutdown following the 5min pump overun timer period when...

"Firstly, good luck with a 400 series". don't understand, perhaps you could expand on this statement. your comment on abv, as I said valve passed 2 litres /min pouring water directly into it. = Zero diff pressure should equal no flow. My question was is the bypass line being always hot, and...

Would much appreciate some answers to observations I have made regarding my recently installed new boiler. I have an open vented system for heating and a non vented mains pressurised hot water system. The system is wired in traditional S plan mode, using the supplied boiler contacts 3/4 to...

Yeh mine came with a thin rubber sheath to cover the bolts. I purchased it from World of Baths and have asked them to supply me with the manufacturers instructions, no reply to date. As an aside I would recommend never to purchase anything from these people, they only want your money and no...

Just fitted my first frame to support a wall hung WC. The frame was supplied with two 3/8" lengths of threaded stud to support the WC. The WC has two approx 3/4" inch holes in the ceramic casting for fixing. No manufactuers details supplied on how they recommend the WC to be supported. Just...

Ok thanks very much for help, much appreciated.

Thanks for info guys understand the message now. Unfortunately i'm a pipe short as currenly the vent is teed off the HW return at the cylinder up in the airing cupboard. (gravity system)The feed is in 22mm which runs to the boiler pump for CH so I could use that for the new vent, but would be...

[Fitting the pump on the flow, after the open vent, then the cold fill (that order is important, creates a positive pressure system.] Thanks for that good point, what do you mean by after the open vent then the cold fill? Normally this is just a single pipe with the fill or vent teed off...

About to upgrade to to unvented HW System, but keeping vented boiler system. Previously my pump was fitted to the return line upstairs near cylinder (boiler installed on ground floor) The logic in fitting to return line was the temperature was lower, thus allegedly pump duty/life longer, seems...

The pipes you have in the floor could prove to be a problem, but usually this would occur through the flushing and cleansing process rather than just the slight increase in pressure. If you live in a house, then the pipes downstairs will be at about 3/4 Bar pressure anyway. A sealed system...

Having decided that I like the look of the Valiant system boiler, and the Heatrae solar unvented megatank cylinder to replace my existing equipment. I had a quote from a medium size plumbing company who suggested the Ariston boiler and cylinder saying there cheaper just as good and unlike...

What planet do these people think they are on. I've just had a quote to line my chimney with 6" ss flue liner at over £1500. When I asked for a breakdown I was told materials and labour was about 50%0/50%. The labour being charged at £55 per hour. x 2 men. I could hire a chartered engineer...

Thanks for confirmation, it is what I expected but I wanted to make sure Cheers PS: any thoughts on this ACV "tank in Tank" system, (which seem to be prominent on this site) versus Standard Tank with heat exchange coils. --------------

Thanks for information, very useful, will go with option one.

Having previously been in the electrical industry for more years than I care to remember, I now find that since 2005, I am no longer considered competent by this government (yes the same government that has competently managed the UK Banking system) to carry out simple improvements to my home...

i'm planning on installing a twin coil hot water cylinder, the second coil for a future solar installation. Should the boiler go the bottom coil and solar panel to the top or vice versa. Views and reasons why please. Also what about an option to put both coils in series
