I went ahead and did it. Started today. All roof off. New battens and membrane and nearly tiled all in one day Used copper nails for the slates and gold screws for the battens Actually a lot quicker than I thought. Still extremely expensive for one guy and a labourer. He will finish tomorrow...

What sort of cost would a 8 square metre roof cost to do ? Access is fine and no scaffolding needed - So I guess it would be a few days max for a roofer and a labourer Wont be suprised for people to ask for a good few K just labour to do that work but i d love to know what the approx price...

Some of the tiles are cracked and some of them are powdery - So I just was not sure that a repair is the way to go Why do you believe there is plenty of life left in the roof? Here is a close up showing the stse of the tiles - Yes I can replace the few that are near the top and seem the worst...

The repair will be to put lead underneath the last course of tiles to help the water run off into the gutter and avoid entering the ceiling and causing the plaster to crack

Hello I want to check with forum members if this roof is perfectely ok or needs replacing? And whether this is welsh slate or spanish slate if I want to replace it? A lot of our neigbours have had their roofs replaced and I do have a leak which has been difficult to repair and still lets in...

Thanks - I think some rads are on one pipe and others are not - Is it simple to tell? One thing I do know is the flow and return do get hot quickly so its not the case that the return delta is massively low The low loss header wont seperate the potential dirty water in the radiators from the...

I had a valiant master tech boiler installer come to me today - It was a funny experience - To keep it short his advice was: Install a sealed system on the one pipe Move the cylinder to the garden adjacent to the boiler When I asked about the pressure and leaks he said "If it leaks its a...

Thanks - I also heard valiant will clog up very easily because of sludge even if if cleaned so I was pointed to Intergas as the best for dirtish water - My pipework is steel so there wil be corrosion even if inhibitor added. I Was aware of the differential between flow and return but advised...

I did not mean to cause offence - I had three gas engineers and the advice ranged from use a combi, rip out and start again and the final engineer was 5K for a valiant ecotec 438 keeping it open vent So I turned to this forum to get the real inside information - I realise that a site visit...

Thank you so much ! I keep getting told especially from this forum that an Intergas boiler HRE OV is the only suitable boiler to choose given I havea one pipe system and big bore pipework - I think I ll take the 30KW choice - I have a gas enginner who replaces combis all the time - He has asked...

Wow - Thank you - This is the level of scientific knowledge that this forum beats hands down to installers who just guess - Really grateful indeed! If I went for a 30KW or 24KW Intregas HRE OV as this forum seems to suggest for simplicitly and one pipe systems do I still need a 8M pump?! And I...

Hi i have solid walls no insulation at all In the loft I have 100mm loft insulation - Thats all

Very good points and am grateful - I have not checked flow and retun temps. I guess you need a thermometer for that yes? I have an ideal mexico 2 BED 125 which warms the house nicely - Was actually unsure whether to get a 24Kw or 30Kw. The installer wanted to fit a 438 valiant which I think...

Thanks that is really helpful - I think the installer like many others are confused and think one pipe system means a PITA - The potters buy guy said that just earlier The pipework I have is wide bore so 3 inch pipework so I thought thats why the pump was specced to be so powerful When I ask...

Thanks so as an engineer - Whats the correct way to size up a circulating pump? Is it volume of water when you drain down the heating sytem? Height of FandE tank or some other way?

Thanks - Yes I have a one pipe system - Does that improve the amount of "head loss" I need? System worked fine with a DAB VA pump so do I go for the UPS2 or UPS3?

Thank you - I dont quite understand the head loss - Its in a two storey house with a loft so the house is about 6M high - I do have three inch steel barrell pipework rather then copper pipes. I have 17 radiators which are cast iron I want to replace odeally with an intergas ov hre boiler and...

I have a DAB VA 65/130 pump at the moment - Grundfos website states a UPS3 pump is a replacement - Should I really go for that or for the more expensive UPS2? Somewhere I was reading a UPS2 has a bigger impeller and therefore better for older systems which might have sludge or dirt
