There is hydrogen embrittlement as well. Anything iron based has to be changed. On a more general note, and I keep hearing this 'ASHPs only work in a well insulated, airtight house'. This is nonsense, fit the wrong size heating system to an house and it will not be optimal. The cash cost may be an issue, but that is mainly because we are not paying the existential costs combustion technology.

Mine didn't, the sound card kept failing, Sony never got it sorted.

That is a bit pricy. Worth more than the house.

Coleman make a fridge that runs on gas or 12V. Worth having a look.

I took a punt on them, but the serial numbers checked out ok. I am not a good a good enough programmer to write a python scripts that can automatically insert the serial number into the scripts, so do it manually anyway.

Rules of Curling Teams of four take it in turns to curl two rocks towards the target area with the scores being counted after all 16 rocks have been sent down the ice. International matches have a time limit of 73 minutes per side with two timeouts lasting a minute each. 10 minutes and one timeout are permitted per extra end in the event of a tie. The stone must be released its front edge crosses a line called the hog. Foul throws are removed from the ice before they have come to rest or in contact with other rocks. Sweeping may be done by two members of the team up to the tee line, whilst after that point only one player can brush. After the tee one player from the opposing side may also sweep A stone touched or moved when in play by a player or their broom will either be replaced or removed depending on the situation. The team to go first is decided by coin toss, “draw-to-the-button” contest or, in Olympic competition using win-loss records. Subsequently the team that failed to score in the previous end has the advantage of going last, called the hammer throw. A team may concede if they feel they cannot win, although depending on the event and stage of event they may have to wait until a certain number of ends have been completed. Fair play is of huge importance so there is a culture of self-refereeing with regards fouls and this is a big part of curling.

Electricians on an hourly rate.

Not Desperate Dan.

Or a proper one in Cornwall, Ontario, Canada.

Have you done some room by room heat loss calculations? Takes a lot of the guess work out of it, and not as messy as plumbing.

A town in Uruguay.

That is why we now have safe zones.

The electrician that wired my house, put the light switches a few metres from the external door that is used the most. Makes me wonder what goes on in peoples heads.

When you look at some thing that were done 'in the olden days', it makes me wonder what they were thinking. Socket and light switches are one of them. Why would anyone put sockets so low to the ground. An extra couple of feet of cable has never been that expensive.

You don't need my help. Gaudi had a cool house that was all wonky. Just remember how he met his end.

Going to try and get this thread locked for 24 hours, and then never unlocked. I have found out how to make my tool 12 inches long. Fold it in half.

Helps if you have some flooding as well. London seems to get more of it than Cornwall.

You are using the wrong tool to check it.

Narrow boats have very small galley kitchens. Most people, in my opinion, go overboard with their kitchens in their homes (no idea what your house kitchen is like). Si my question is, assuming you did not eat 'boy scout' tinned beans and sausages, did the boat food taste worse than the home food?

UFH runs at a higher temperature than ambient, and you can treat the ground as an infinite heat sink, with a mean heating season temperature of about 8°C. You also have a lot of floor area. Remember that U-Value is W/m2K, so a lot of area at a higher temperature means greater power going though it. So imagine a wall of 10 m2 and an inside air temperature of 20°C and an outside air temperature of 2°C, if the U-Value is 0.15 W/m2K, the losses will be 27W. Now imagine a 10m2 bit of floor, that is at 30°C and the ground is at 8°, with the same U-Value, the losses will be 33W.

There is no real advantage site an ASHP in sunlight, they are not solar panels. They use the air, which does not change much in temperature, especially when it is drawn in by the fan.

As long as it is not totally overgrown, and you have a metre and half diameter circle around it, it should not be a problem. Any air that is cooled is soon dispersed, and it only comes out a little bit lower than ambient. I would be more concerned about losses though the pipe runs, as well as electrical losses depending on cable sizing and length. A cubic metre of air has a mass of about 1.25 kg, and a specific heat capacity of around 1 kJ/kg.K, which is 0.0002778 kWh. So if that cubic metre of air is cooled by 5K (or °C), you get 0.00173625 kWh of energy. To get a kWh out of that air, you need to shift 575.95 kg of air, or about 720 cubic metres. Sounds a lot, but is not in reality. About a third of what my car sucks in though the air intake in my car when I am doing 70 MPH.

It is usual to have flexible pipes from the monobloc, the manufacturer specifies the length of them. This is to stop vibration from travelling along solid pipework. So it is usual to fit them in a service channel/duct. Yes.

Can you double that thickness?

Good suppliers/installers yes. I would expect them to spend several hours on doing a detailed heat loss analysis, which would include daily weather data from your nearest Met Office station. You can do a lot of the calculations yourself, they are dull and boring to do, but not actually that difficult. The MCS site used to have the methodology, that every installer was meant to apply, on it. It is pretty good. Regarding your UFH, how much insulation, and what type, are you fitting under it?
