Not if they heat their house to 25°C

Was thinking more about DIY installation of the finished product i.e no F-Gas certificate or G3 for a cylinder. Not saying my 93 year old mum should fit one, but a good DIYer should be able to.

I think so as well. As well as do-able, DIY-able would be useful. Take a lot of the mystic our of them and they are just another energy source.

Move to Cornwall. One of the most polluted roads in the country is here.

Fridges and freezers, which are basically the same, cost very little. Ok, an ASHP has a couple of heat exchangers and fans, pumps and valves in them, but basically basic engineering stuff. One of the problems with the UK markets is that we are a high mark up country. Retailers don't like adding a small percentage, they like to add lots of £, regardless of the base price.

Kind off. Imagine a wall facing the wind on a rainy day. The rain is the particles you wish to remove. Wind and rain hit the wall, rain sticks and drops down in, the air, finds a path out the top and sides.

Yes. We all want highly modulating heat pumps, with cooling, and zero parasitic losses. CoP Greater than 4, at an operating output temperature of 75⁰C and no frosting up. And silent. For less that £500.

Good saying. The British have a similar saying. "We are and Island Race".

Usually round. Not sure of the formula used, I was the production engineer, the 'lads in the design office' used Q, A, PL a lot. Think it was basic aerodynamics. All I remember is they used to use my company car to get to Silverstone where the Dyno was, and use all my fuel. And break my favourite tapes.

And wood burners. There was a comedian on a radio show. She pointed out the many British (white English I assume) want to get off grid. Her family came from an off grid society in the Punjab. House swap is the answer.

Was that in little bits, or contiguous. Don't know about your bit of the country, but down here it was clear skies all day.

Not on the Budget Airlines this week.

You missed something. Basically there are rods that deflect and accelerates the air, but the particles, which have more momentum, keep on going straight and hit the rods and become stationary, then gravity pulls them downwards into an entrapment area (a bucket). As the rods can move slightly, there is a shaking effect that can enhance the removal of particles. The ,number, diameter and density of the rods is what governs the size of the particles removed for any given airflow. Been 25 years since I worked in the air filtration business, but apart from cyclone filters, which we did not make, the principles are the same, Actually cyclone filters are the same principle. You either make a hole so small that particles cannot physically get through, or you use the different densities, acceleration and gravity (remember the true definition of acceleration, and change in speed AND/OR a change in direction, why the moon is accelerating around the Earth, and the Earth-Moon system around the Sun). There are oil bath/other solvent filters that, once the particles are in the working fluid, can then be filtered out traditionally. And electro-static filters that, depending on the surface charge of the particles, can be quite good, but not as good as some manufactures claim as they can repel some undesirable particles and increase the overall level of that particle in a room. All filtration system need regular maintenance i.e. cleaning.

Never been there, but I should go, one half of my family are from there. Called Türkiye now. My last 3 trips to different West Indian islands has been interesting as I never turn the A/C on at night, just open windows. Just allow the sea breeze to do its job.

Welcome Sounds like you are involved in an interesting engineering project. The first things that springs to mind about the British lifestyle when it comes to heating, is that it either on, or off, and usually off at night.

Is that for the whole site (0.6 Ha), or 'per some land area i.e. m2

Horseshit.

It would be a guide for people that bother to read it, on here. We cannot educate the world. Thinking a bit more about it, really need an ex copper to ask questions, they know how to go about it. I think we have an ex copper on here. The basic questioning technique when you first meet someone new is always useful. Who, What, Where, When, Why + How

Really a matter of asking the right questions before employing them. Maybe we need @ToughButterCup to make up one if his many, many, lists. A set of 'conversational questions that drill down through the skill sets to find out if someone is SB or BS.

Not going to mention it either. Will say that the standard of driving has plummeted this week. But on the bright side, did manage to get in a free parking space in town.

Thy should accept some charge at below the phase change temperature, but the heat capacity will be lower.

@Onoff will be along soon. You possible know a couple of people I know. I turned down a free trip to CAT, my day trip, back in the 90s put me off. From what I heard it is a bit more down to earth now.

Personally I think that is a failure of the engineering design. Do a search and see if you can find the manufacturer and ask their opinion. They almost certainly want their product to be fitted correctly.

Like children, that cost nothing to make, you will soon find out, they are not 'free'.

The badgers around these rural parts get drunk on people's eco friendly slug traps. I see them sleeping the nights excesses off on the side of the roads. Newspapers are not the only think that are black and white, and red all over.
