I agree that it has to be a done deal before, just confused by the language and examples used. I have a composite plastics systems that has overcome a longevity problem. Nothing special in itself, and it is up for sale. If I ever manage to sell it, then the new owner can do what they like with it, even give it away for free to the whole world. I am not putting an NFT on it, though maybe I should. That is odd, or the way you have said it is. When I did my first two degrees, the university technically owned the copyright. This narked me as I was paying and did all the work. Except I didn't. I only paid for part of the course and it was graded by university employees, and, I assume, is still being stored in the library. When I started lecturing, part of my job was to create 'module boxes'. Basically lesson plans and schemes of work. It was fair that the university owned these, they paid me to produce them. They I don't think they noticed that I had copyrighted them. If someone comes along and changes them, that is nothing to do with me, the university bought them, I don't feel that my reputation is at risk. There is a large, ongoing debate how patents and copyright are stifling innovation. I tend to think that it is. I also know how difficult and expensive it is to enforce ones IP, generally greater than any financial advantage.

@CharlieKLP, @Roger440, @the_r_sole Just to make it clear, as I am struggling to understand what things you are protecting by not sending CAD files, which are just drawings really. So what are you protecting? What are the legal complications? What is wrong with people working to your files, rather than part of your files?

Ask @Gus Potter

That tells us nothing. What is the expected heat load for the house. This is often expressed as kW per ⁰C temperature differences, or as a maximum heat load i.e 4 kW. Without looking up the details if your heat pump, do you know the maximum thermal output? Sounds like he disabled the resistance heater that is used for the legionella cycle, which would not have been needed as your DHW is taken care of by the Sunamp.

At that price, a diesel generator is viable. And you can get some thermal energy off it. I think that basic unit prices will drop in the next 18 months. Future prices are currently 2/3rd of the November peak price. http://www.livecharts.co.uk/daily_charts/daily_charts.php

I put up a hanging pole, even made sure that coat hangers fitted properly, it is still too close to the wall. Put a Swiss Cheese Plant there, should grow well.

Does depend if it is a warm or cold roof surely.

Sounds to me like you are charging for 1000 bricks, but only delivering 750, claiming that the other 250 is for complicated legal reasons.

Without knowing the heat loss of the house, and the DHW needs, and the size of the heat pump, it is just speculation.

Usually on joist I think. Everything built in the UK gets wet, most houses stay up.

I think you mean kW, the power the ASHP is drawing, not kWh, which is the energy it has used. If you are getting frosting at 6°C, some sound wrong especially if you are not getting enough time to heat the slab up a bit.

People may want to pay for a design, then get others to do the work. This may mean that things get changed. Claiming it is a 'legal thing' is a pretty poor reason to not give a customer what they are paying for, not as if a house is a service (to crib a software term).

It is how TVR did their development.

What do you consider a smaller house? We have an architect on here who showed off his 'small house' conversion. The place was nearly 3 times the size of my house. Same architect used to teach, as part of his course, he got his students to read the dictionary and find odd words to use to describe their creations.

Not sure if anyone has mentioned it, but there is the IP side of things. Some people get a bit narked when they ask an architect to design a house, then all they get is a small PDF, with no dimensions. If people pay you to design them a house, they want full drawings/access to CAD files without any restrictions. That is what they are paying for. My very first post, over at the 'other place', was about open source house design. In a former life, I worked as an automotive engineer, house design is a piece of piss engineering wise. Not as if a house has to corner at 150 MPH, have 2 tonnes smack into the side at 30 MPH, have the safety feature do nothing for nearly all the time, but must work once when needed. My old banger of a car has electric windows that work faultlessly, doors that open with a remote control and disables the alarm/immobiliser, and on a good run, can do 70 MPG. Houses are not much better than caves when it comes to design.

Did the windows turn up on time and fit. Personally, I would keep quiet about that as most of the projects are disasters. And avoid the words eco and sustainable.

No, shed light.

Can you set your ASHP up to do the DHW between 11AM and 2 PM? (or whenever your PV is most likely to generate the most, on average). And have a diverter to directly resistance heat the DHW in the summer. Only if the diversity allows it.

Get a half decent battery powered one.

That is about 2/3rd of my total lighting load.

Plus yourself that may be adding 100W.

It is even worse in one man bands.

They need to get there act together then. https://supplychaindigital.com/sustainability/analysis-how-buoyant-tesla-defying-global-chip-shortage

Boat ones tend to be low power devices (200 to 600 W), put them on land and they will produce even less. Power generation is proportional to the cube of the windspeed.

That is why there are incentives to install them. It is an immature market in the UK at the moment, but that will change. I remember the same argument used during the PV bubble, now you can pick up kit cheaper than windows.
