Much of it depends on how 'pretty' you want it to look. You could go for a simple roof like @joe90 suggests, though I would use GRP, and then fit PV bolted to rails. You could use a roof intergrated system, saving on roofing materials. Or even solar slates, so that it looks like a normal roof.Only a case of costing the up really.

Isn't that latent heat?

Purely as a second thought, I always leave a reasonable gap between the bed and the wall, it stops 'rattling'.

Thank you. It will be a very useful resource.

Can you set up a screen video capture, maybe with audio, then we can all see how to do it.

Or with an angle grinder and sanding disk. I bought a cheap multitool from Lidl. Works alright, but always pick up the grinder first.

Don't most designers have tie ups with manufactures/suppliers and other related industries. May be worth you looking into that income stream.

Would it not be better to shave part of the bed leg down.

Won't the boiler size be a bit marginal, works out at 16 kW/shower, so about 15 litres/minute. Actually that is not a bad flow rate if it is actually achieved, mine is 11 litre/minutes and quite nice.

Yes, I think it is the lack of skills in the plumbing industry. CO2 heat pumps have been around decades now.

Still has a GWP of 675. CO2 is 1 I really wish the industry would hurry up and move over to CO2 pumps.

Limescale.

Your house is a similar size to @joe90s, he fitted his own I think. And yes to UFH if you have a decent amount of insulation under it.

Did you pay by credit card?

I laid my own, was not that slow, or hard to do. An angle grinder with a sanding disk is your friend.

Not got zoom, but I know it goes on mute quite often. I shared a flat with a Kiwi Sax player. I had to move out. Though he did do a good version of Bowie/Mercury Under Pressure.

My house used about 85% on the cheap rate. The price difference is 12p/kWh. So in my usual usage of about 11 kWh/day, upping that by 13% would save me a whopping 13p/day. If all my power came in free, then I would save £1.3/day, £465/year. Sometimes it pays to use more.

All comes down to the nature of heating and cooling. With a cooling curve.

The main one is power, it is no good having a really good CoP but only delivering 500W. One of the problems with heat pumps is that people forget what they do, and how they do it. Then get bogged down in details like thermal stores, flow rates different temperatures for different jobs. Main thing to remember is that space heating and DHW are done at different temperatures, different times and different flow rates. The 3Ds.

Well you have a lot more than 1kg of air to get rid of, but that also means it does not get so hot. But if you do fit a very large fan, and grow mullets, you can make so old school video. The only people that say they don't understand today's music, are the ones that don't get it. I don't get it.

Yes, they were only a little disaster. My house has 200mm of mineral wool insulation and good airtightness. It was a pre-production model constructed for testing. The plastering is crap though.

It is all to do with the low specific heat capacity of air. Air is around 1 kJ/kg.K. In more understandable units, that is 0.00027777777777778 kWh/kg.°C So if you have a system that is drawing 500W (a small fan heater) and it runs for 1 hour, that is 0.5 kWh or 1800 kJ. Now a kg of air has a volume of around 0.83 m3. So to keep the air at the same temperature (assuming no other losses), you have to shift that air away at a rate of 1500 m3/hour. It is more usual to use the litre/second as a unit, so that is 417 litres/second. Quite a lot.

It is all to do with the condensation risk. The risks are different for different climate regimes. I think this caused a few problems when the UK built TF in the 1980s. Since then a lot has been learnt (my place is a late 80's TF and not a problem here as far as I know).

This is really a failure of the auctioning system we currently use, with better management, it should become a thing of the past.

Can you put all the electronic stuff in a ventilated area, then pump the excess heat out. Or go capella. Being someone that 'speaks' BSL, hours of fun can be had singing in a public library.
