They spend a lot less on land, the professional fees are spread over many houses, completely different purchasing and supply chain systems, equipment utilisation is much better, design is standardised to reduce waste and time. If a small developer makes any money, it is because they take so long to build that house prices have risen. They would have been better off just buying land and getting planning on it. There isn't really brass in muck.

One problem with putting in a header tank in a living or sleeping area is that they can be noisy.

You should be able to isolate it all very easily. It is part of the design criteria.

Get a washing line, costs 2 quid (with pegs from Poundland) and uses 0 kWh.year-1. If you are doing the roof with Dormers in it, will these cause any shading issues?

You could try totally isolating it for a few hours. So isolate invert, isolate the modules and flick the MCB at the consumer unit. The in the morning turn it all back on (in the correct order). Be thankful it is winter when it is not generating much.

Not to me it does not. You need to work out how long the heat source will run for. Water takes 0.0116 kWh.kg-1.K-1 So 10 lt will take 0.116 kWh.K-1 So it also depends on the hysteresis you are working to. 5 K would be fine, 2 K would not.

Do you know what flow rate you have coming into the property?

By working out the power needed and runtimes. Then compare it to what the heat pump manufacturers recommend. Or put in 100 lt if you must work with a gut feeling. Oversize is better.

What does it say here about shower flow rates? https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/504207/BR_PDF_AD_G_2015_with_2016_amendments.pdf

You gone Bodmin.

Have you given MacSalvors a call?

Meet you all at the Swordfish Inn. Only place to party.

We get boat loads of better stuff coming into Newlyn every night.

Cannabis Farm?

@Dave Jones "knows for a fact" that heat pumps can't work. We had a system that was successfully doing that and the government pulled the plug on it. I do often wonder where parliament gets its information from, and how they can so consistently get the wrong end of the stick.

You can read all about it here. https://www.bp.com/en/global/corporate/energy-economics/statistical-review-of-world-energy.html Seem to remember the UK has had 3 years worth of gas left, for the last 15 years.

BoE raised interest rates today. 0.25%

Worth remembering that epsilongreedy is highly qualified in economics, thermodynamics, the social sciences and property development. And probably in import and export paperwork.

Several people on here have used an architectural technician. They seem to be the people that understand all the rules and regs. At least they are not irritating little farts.

I think you have to notify the DNO about the location of the isolators as well.

Right. Just as a general note: Always switch the AC side off first to isolate the load from the modules, then the DC side.

As you have a 5.1 kW system, why did you go for a 6 kW inverter? Or is that the very maximum it can take, rather than the nominal value?
