Mine did. We had some big SW storms a few years back. Noticed a damp patch in the bedroom ceiling. Seems the wind had got under the loft insulation, then, when it had flopped down, had moved forward a little, just enough to allow it to wick up water. Easy fix, just pull in back 2 inches. Neighbour has the same problem, told him how to sort it, 4 years on and he is still complaining about the 'leaky roof', (expletive deleted)ing nob. I have tried, on two PCs to print your PDF off. Can't print it.

Your slug. Reminds me of the quip about 50% of the population having legs.

I googled it, this came up.

Is this for real. Can't see anything on Companies House about them. There is a David Lindsay Electrical Service, same name as the MD.

My view this morning. Bit too much bunting for my liking.

So less that half a gram per m² every year. I don't know how deadly these nitrates and phosphates are, but at a mean delivery of 1.3 mg a day, I would like to see some peer reviewed evidence that it is a real problem.

Nicer falling onto a carpet than a road. Should have asked him to deliver it for free. Would have kept him busy, and 2 paces Infront of you all day.

Not had a chance to read it yet, maybe after I have slept off the car journey and an early lunch.

The UK has not been very good at managing small scale, district heating schemes. I think the cost of enforcing non payers is too high. Developers probably don't want to pay too much for a network upgrade. They are not very creative when it comes to buildings. They would struggle to find space for a 200 or 300lt cylinder. Anyway, customers would complain because they would not be getting all their power for nothing, all the time. So developers probably buy an existing solar or wind farm and offset credits.

Worth knowing, reasonably well, about insulation and ventilation.

Shall print it out when I get up country and have a good look though.

Brilliant

That is the limiting factor. But if you could get a half decent HP for a few hundred quid, as opposed to 3k, then the sums change. It also depends on what you are being charged for a kWh of power, and what your income is. Corby Leisure Centre had a project that did this. It extracted waste heat and dumped it in a lake. Then, when heating was needed, extracted, via HPs, and pumped it back into the building. Was a disaster, and to the best of my knowledge, never tried again. The Jubilee Pool in PZ tried to heat the Art Deco pool with geothermal energy, then a GSHP as they hit problems. Again, a disaster, especially considering the Atlantic Ocean was less than 10 metres away and they already pumped in seawater. I did suggest that they fit WSHPs, but was told, in no uncertain terms, that the technology was ground breaking and someone had to be first to do it. Pointed out that they were not first and could I look at the heat loss calculations please. Think I pissed them off then. Knobs.

Yes but they do it, well mine does . I don’t get what you mean? You could have 3 individual machines, better tuned to the temperature ranges. That would up the efficiency. One of the reasons that an A2AHP can give a CoP of 4 to 5 is because it it not heating water to 50⁰.

You need to start a topic on this. I think a few of us would like to give it a go. I would. 2.4 kW is plenty for me.

Yes. You are asking one machine to work over a relatively wide range of temperatures. i.e. DWH OAT 0°C WT 50°C, Heating OAT 5°C WT 35°C, Cooling OAT 26°C WT 12°C. Engineering can overcome much of it, but it has no control over the weather, or the power demands of some users.

No one within the M25 is in any sort of poverty. And everyone in Cornwall is. End of.

Isn't that what an EAHP does, but then just gets ducted in differently. I like the LINUX approach to heating. Do one job, but do it very well. Heating, cooling and DHW are 3 different things, try and mix them into a single unit and you have to compromise. As any married person will testify to, compromise just results in 2 miserable people.

Not if they heat their house to 25°C

Was thinking more about DIY installation of the finished product i.e no F-Gas certificate or G3 for a cylinder. Not saying my 93 year old mum should fit one, but a good DIYer should be able to.

I think so as well. As well as do-able, DIY-able would be useful. Take a lot of the mystic our of them and they are just another energy source.

Move to Cornwall. One of the most polluted roads in the country is here.

Fridges and freezers, which are basically the same, cost very little. Ok, an ASHP has a couple of heat exchangers and fans, pumps and valves in them, but basically basic engineering stuff. One of the problems with the UK markets is that we are a high mark up country. Retailers don't like adding a small percentage, they like to add lots of £, regardless of the base price.

Kind off. Imagine a wall facing the wind on a rainy day. The rain is the particles you wish to remove. Wind and rain hit the wall, rain sticks and drops down in, the air, finds a path out the top and sides.
