Not they way I can route them. Been pondering it for years and think I have found s relatively simple way to hide all the gubbins. Just need to fid a decent route for the power cable.

Yes it would be, but not worth the expense and hassle on a low value house. Being such a low user of power <4MWh last year, none of the options really stack up. But I would get a more controllable and comfortable house, which would be a selling point, though I am considering renting the place out as I am spending more time 'up country' helping to look after my Mother. What I have spend in filling the car over the last 4 months would have bought the ASHP.

Yes, and I hate it. No point replacing something you dislike with something similar, and disliking that as well.

I still have. I like the reliability of them. This is my dilemma. Buying a small ASHP is not that expensive. Fitting it is as it will require major work around the house. I don't like to see exposed pipework and hate radiators. So comes down to a combination of skirting board emitters and plinth heaters I think. Then working out how to do the DHW.

Clever bloke he was. https://www.engineeringtoolbox.com/euler-column-formula-d_1813.html One day I shall get to fully understand 'moments of inertia'.

That is interesting. I studied this, in part, at university. For my area (Cornwall) I found wind speed and direction a good predictor of both temperature and irradiance. Never looked at other locations though.

Seem to remember learning about that. Cathetderal builders put heavy statues on the wall tops to help stabilizer the structure. Suppose it works the same a pre stressed concrete. Does it increase the risk of buckling if the mass is too great.

You want pink wee? My knee can arrange that for you.

That idea I like very much. Also helps stop the sound of bird's claws. The mobile homes that are in exposed areas down here have cables attached. Then spikes in the ground. They survive 100 MPH winds and 120 MPH gusts ok.

where will they create least noise when on boost?

Closer to me than home. When I lived in Watford, my g/f bought a 4 quid item from Newcastle. Drive there and back on s Sunday to pick it up. The tosser that we got it from did not even offer us a cup of tea. Still, got to see the Angle of the North.

Coast to about the furthest inland. I come from near Penzance.

Yes. I am not that far from Bicester ATM. Shame I cannot read them when I am driving home. Could get the whole set done during the 12 hours I am wasting every weekend.

If I get around to it I will reread the regs.

You may be right, I can't remember. Says here 1.1 https://www.burtonroofing.co.uk/blog/u-values-and-building-regulations-for-insulating-your-home/ If I was not on the phone I would download the regs and check.

I could not turn most of the cookies off, so they can f off.

If you are having UFH in the slab you really want to improve on that. Top of my head I think roofs have to be a better U-Value.

Do you refer to the built-in Mixergy coil? I would imagine any night time tariff, and daytime solar PV discharge would nicely play together with it. It seems that other pumps do that too (perhaps not 65C, but 60C?) I considered that, and whilst it (apparently) boosts your SAP a lot, I am yet to establish if I will ever see a return on the £500 to £700 unit (multiplied by two out of three bathrooms). Yes, this is what's rather logical and "free". But will I in effect overheat during the day? Or would I hope that MVHR would, somewhat, redistribute the mass of air across the rest of the rooms? Not using a consultant, hence me trying to understand Hebrew by myself. Also, specifiers / suppliers like BPC , Nu-Heat and so on will specify whatever they want to sell, as long as their choices fall within the bands of criteria. So not unbiased... Above all, whilst I am trying to find a holy grail, I want to make sure that I am not overpaying for solutions that will never see me any return. I am not a purist, and not a tree hugger, either. But if I could make a wise choice, and not kill the planet, then surely I would feel better too. Also, it is likely it will not be a forever home. If it lasts us 10 years, then I think we have done alright. Chances are, we will build another one in 5 years time. There is so much there that it cannot be easily answered. What size house, number of occupants, embedded renewables, U-Values, and in and on. Is the place still at the design stage, or has construction started?

It is a starts. Rather mixed units.

Did you tell them that you want a large electrical shower i.e. > 15 kW

Sorry, I don't think I understood you. I am just quoting "the brochures". Your house will have a heat load, basically the power the heating system needs to supply at different outside temperatures to keep the inside at the temperature you want. Often expressed as kW/⁰C. This is what you need to know when choosing any heat source. It is more important with an ASHP as the performance varies with outside air temperature and humidity. ASHP and gas/oil boilers are calculated differently, even though they are doing the same job usually.

You will need a very large electrical cable. You may be better off with a well insulated cylinder and a shower pump. This does not need to be in the caravan.

What are your calculated heat loads at those temperatures?

11 panels per string ( 22 in total ). So around 500V then.
