Anything with a Peugeot XUD engine would still be going. Landrovers should be classed as EVs, the body panels and the rivets make a mice battery.

You could try a wallpaper steamer.

Not sure what you mean, PV?

Only mechanically. I like the look of them, though they are cramped inside, but then so was the Discovery. A farming mate of mine had one, I was always having to go around to fix it, then he got a Disco, that was just as bad. He ended up with a couple of Troopers, had little trouble from them.

Good stuff.

No idea what your weather is like at the moment, but here (West Cornwall) it is is 9°C and 99% humidity. Good test for MVHR (wish I had it, got window open as I am cooking).

Welcome. First things first, a rough drawing, with dimensions of your house would be useful. If it is similar to my old Victorian terrace, the thermal loses where dreadful. Knowing what I now know, I could have put it right when I gutted the place, hard to do after the event. Really comes down to how much you want to spend, and how much work you do yourself.

Won't the MVHR keep the condensation risk very low?

It will be a combination of the power that the ASHP puts out, the CoP it is trying to run at (if this is a settable parameter), the power the radiators can deliver at and the temperature differences between the indoor air temperature and the radiators, and the overall heat losses of the building. It may also be a mismatch between the ASHP, buffer and radiators. And that is before variable weather is taken into account, this can affect the CoP and the building losses. A cold but sunny, still day will be very different from a blustery, rainy day. Usually combustion boilers have a greater power output as a ratio of mean power needed, this can mean they may heat up a building faster, but they do it at the cost of efficiency.

Do it properly with GRP. Then forget about it for 40 years.

Anyone want to buy a time-share apartment, off plans, in Spain. This sort of thing is not new.

Airtightness and insulation, then you can probably swap the GSHP to a much cheaper ASHP. And look at your DHW usage, water does not need to be stored above 60°C all the the time and a shower does not need to use 150 litres of water

Hard to tell, but usually it is a filled polyester resin used to cast these. So a polyester car body filler would work fine. Then CT1 @pocster's favourite, o the fittings.

GRP it.

There is down here, hospitality workers (12% of the area's economy) and non essential shops (about 35% of the area's economy). Even agriculture has had to lay people off because of the reduced demand for some crops (generally the posh things that restaurants buy). Fishing is hard hit as well. Then there are the unknown people that have had reduced hours because they support the other industries. Last year, 39% of the workforce was on genuine furlough in Newquay and St Awfull, and the county as a whole is at 33%. The Cornish would rather be poor than have anyone tell them what to do, but like the EU (we are still getting some) and Central Government handouts. I would happily be on furlough till I retire, then I would get a pay rise. I think it is money that helps, certainly more than low paid jobs in unsecure employment, which is what we normally have here. People seem pretty happy.

Can you put a pipe in and then pump out. A pipe can be cast in concrete.

As other have mentioned, if it is draughty, then that is a problem.

How much, 50mm, 200mm? Basic 'Celotex' type insulation has a thermal conductivity of 0.03W/mK So 50mm will give you a U-Value of 0.6 W/m2.K, 200mm 0.15W/m2.K Oak (as an example) has a thermal conductivity of 0.17 W/mK, so a U-Value of ~11W/m2.K

I wish I had a well in the house, I pay £8 a tonne to get water in and out of the place. It costs me more to get the water than heat it. Use this valuable resource.

@pocster Offer and Acceptance. At long last.

Welcome Without more details, it is hard to tell when is happening. Is the floor you refer to as joisted, got an air void under it, it is it full of insulation? What sort of floor covering do you have in the area that works? What are the general heat losses like for the two different areas?

About what I am using at the moment. 1, 3W light bulb and my my laptop (mean usage 8W when in use). Don't get me wrong, I like the idea, but I think just going to low carbon generation is the real answer. Look at this and weep. Nearly 4 times worse. But none of us would have deliver a decade ago that even 100g/kWh would have been possible in 2021. But what we going to do with the dirty Welch.

@joe90 You fitting a bilge pump?

Need a router permanently running though. So 5W or so. My router is my phone hot spot, fine for people that live alone like me.

That is all to do with the designed output, why they are rated in kW A kW is 1000 joules per second. A joule is a unit of energy. Specific Heat Capacity also uses joules, kJ/kg.K This is why, knowing the energy needed to raise the temperature, and knowing the power you can supply, you get the time needed. J/kg.K / J/s
