How did you close or cover the cavity in the end? How deep is it?

Ha ha, good idea. But why would tape cause a problem? Not sure if I mentioned this, plywood is a prolific material in construction: over the rafters, under the rafters, dormer cheeks and fronts, membrane above and below joists, partition walls, tiled over vertically or horizontally, it is used...

Sorry I meant 50mm overall diameter instead of 100mm. I am not sure what capacity I need, I do not think there is a minimum mentioned anywhere? So if there was a partial blockage in the hose you'd not know it for ever. Was my thinking. I did consider vertically up, and down, may still do that...

Hi, I have a cloak room and an ensuite next to each other, in the middle of the house, with no possibility of venting. There is a small crawl space above the ensuite ceiling to house one or two inline extractor fans and ducting hoses. I want to merge the two hoses and route them through the...

No heating in the house yet. Weather was 20C-22C/day and 12C-13C/night in first week, rising to 19C-25C/day and 11C-16C/night the following week. However, 4th week in, dropped to 11C/day and 2C/night. But I think the cracks had already been. Ceilings are meshed with steel beams, largest joist...

Exactly that. Oh the irony. I have been given 100% chance those ceilings will crack but they have not yet. I think now, on the ceilings with a million cracks, the plaster is spread too thin, since I can see the outlines of every single board. Being it too thin it then cracked. Other ceilings...

Yes that is what I meant, a human regulates the intensity of the gas hob ring by turning a button, does the boiler also regulate its burner's intensity ? The answer seems to be yes. I will consider this if I decide to install a boiler rather than a heat pump.

Excuse my ignorance, is it not a major hassle and spills everywhere with very dirty and staining water when you try to remove a radiator?

In a very modern boiler, If the return to the boiler is above the required thermostat setting (HW or CH), would it make sense for the boiler to dial down its gas flames?

You're right I meant radiators.

The heat is given out to air around the radiators that ARE heating up? ( guessing ). You can actually use a thermocouple or IR thermometer to measure the temp on the IN and OUT of the heated rads. I do not think there is too much hydrogen production going on inside your rusting pipes :)

OK, I have done some reading, it seems for the length of 33m MDPE 32mm I can accommodate about 40kW. This is OK for a 30kW gas boiler which was my intention. If I wanted more appliances, would I be able to ask for the gas meter to provide two separate outputs each with its own 21mbar pressure?

So very near the boiler, and while still underground, we connect a copper pipe to the MDPE, so that the copper pipe emerges from the ground, and all is good?

33 meters of 32mm MDPE pipe. No boiler installed yet.

1 and 2 : So all I have to do is connect a copper pipe to my underground yellow gas pipe and all is good? 3: Are you saying that regardless of the mains gas pressure, once it goes past the meter it drops to 21 mbar?

Due to costs I may be forced to install a heat pump instead of a gas boiler. As I am learning about heat pumps, could anyone please tell me, do they make one that can switch the gas flow and cool the radiators instead of heating, if you want it? I have this system installed on another house but...

A few years ago I relocated the gas meter away from the house. I then dug a trench and buried a yellow gas pipe MDPE 32mm, that would run from the gas meter to the house. The heating engineer who visited to connect the services took a look at the emerging pipe and said it is not right and I...

I have thought about this for a while, why did cracks appear only on those two freshly skimmed ceilings, there are many more ceilings in the house with no cracks. What is the difference between those two ceilings and the rest of the house? Factors which are the same: 1) ceiling joists - all...

Neither :-) The joists have first been covered with ply. Then we placed the ceiling boards. About 30 screws per ceiling board and 30 screws per ply board. All ceilings in the house, in all rooms but 2, have been done in this way. The kitchen and living are the only two rooms with cracks and...

Same ceilings freshly plastered a month or so ago
