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.

What is taking that much? How old are these free batteries, or in other words, why are they free? Some SunnyBoys had a settable relay in them that could be used to divert load. Could you charge them with 4 or 8 half decent car battery chargers? (I don't know enough about the chemistry of lead acid batteries to really comment). Can you run some of a dedicated load of a cheap inverter, or even DC (with appropriate switching)?

What is the difference between Light and Hard? You can sleep with a light on.

I know quite a fee, and the last 2 years has been very quiet for them. Write up a blog on here about it. I had noisy neighbours, but after threatening the absentee landlord about it, they seem to have got better tenants. Trouble is the last bad tenant in that house only moved a door away. And now has a small, noisy car, as do his friends.

Why, can't she cook. There is a reason that modern commercial kitchens mostly use induction hobs now.

Only if it is sized I correctly. Put a gas boiler in that is too small and you would have the same problems. It really is time we stopped thinking that say an 8 kW HP is a direct replacement for a 24 kW gas boiler. Are you having PV fitted. That would change the economics of running a heat pump.

And copper oxide, hydride, nitrate and sulphate are just pretty colours in a crystal garden. Good job they still use lead piping to get to the property.

Actually, that is more clever than I initially thought. Turn the pump on and you can store more (OK, you loose a little more though parasitic losses). May be useful if you have extra guests staying.

Hotter water just needs to be mixed with extra colder water. Really makes no difference at all. No. My system is as simple as it gets. A cylinder with an immersion heater at bottom, cold water from a tank in loft, and s pipe out the top to the taps. Works well. Cylinder lasted for about 31 years.
