That is the limiting factor. But if you could get a half decent HP for a few hundred quid, as opposed to 3k, then the sums change. It also depends on what you are being charged for a kWh of power, and what your income is. Corby Leisure Centre had a project that did this. It extracted waste heat and dumped it in a lake. Then, when heating was needed, extracted, via HPs, and pumped it back into the building. Was a disaster, and to the best of my knowledge, never tried again. The Jubilee Pool in PZ tried to heat the Art Deco pool with geothermal energy, then a GSHP as they hit problems. Again, a disaster, especially considering the Atlantic Ocean was less than 10 metres away and they already pumped in seawater. I did suggest that they fit WSHPs, but was told, in no uncertain terms, that the technology was ground breaking and someone had to be first to do it. Pointed out that they were not first and could I look at the heat loss calculations please. Think I pissed them off then. Knobs.

Yes but they do it, well mine does . I don’t get what you mean? You could have 3 individual machines, better tuned to the temperature ranges. That would up the efficiency. One of the reasons that an A2AHP can give a CoP of 4 to 5 is because it it not heating water to 50⁰.

You need to start a topic on this. I think a few of us would like to give it a go. I would. 2.4 kW is plenty for me.

Yes. You are asking one machine to work over a relatively wide range of temperatures. i.e. DWH OAT 0°C WT 50°C, Heating OAT 5°C WT 35°C, Cooling OAT 26°C WT 12°C. Engineering can overcome much of it, but it has no control over the weather, or the power demands of some users.

No one within the M25 is in any sort of poverty. And everyone in Cornwall is. End of.

Isn't that what an EAHP does, but then just gets ducted in differently. I like the LINUX approach to heating. Do one job, but do it very well. Heating, cooling and DHW are 3 different things, try and mix them into a single unit and you have to compromise. As any married person will testify to, compromise just results in 2 miserable people.

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.
