To my mind, reducing parasitic loads is vital for reducing energy usage. Why I worked so hard on doing it.

May have a trip down to the ASHP training centre and see what they know about it. Certainly makes choosing a manufacturer a bit easier, strike Mitsubishi off the list.

Seems other have noticed it as well https://www.greenbuildingadvisor.com/question/mitsubishi-mini-split-phantom-draw https://www.hearth.com/talk/threads/heat-pump-idling-while-your-wood-stove-is-running.184381/

Only exactly because it is a leap year. I heard it from a fitter about 15 years ago. Not sure which day though.

Is there blood and guts, and exploding cars in it. Or so dark and depressing that you wish bed time was your last.

That is dreadful, and probably not taken into account with the CoP figures. I would strike Mitsubishi off the list of ASHPs if the whole range does this.

Had to look that up.

Luckily I am away. Shall get the maid to change the linen before I return.

I think yu are right. Sensible to do it with compressions anyway when DIYing.

To quote you back, easy to say, where is the proof.

You planted your beans yet. If not let us know when and I shall do the same. Then a race is on.

You got scaffolding? My scaffold tower is currently in Bucks for the foreseeable. Pretty close to yours.

You could fit and wire the modules on all your roof. Then connect up what you are allowed to. Try calling your DNO and explain, some people are helpful. The PV team at WP down here are very good. No nonsense engineers.

That is the starting point. Once liquid, it can seep to many places, even travel uphill a bit.

Not sure what you mean by a gantry, but you need planning permission if the modules are over 9m2 and not on a building.

Only 3 old lightbulbs, or 2 if you are blind. Open the case and see if you can touch the compressor when it has not been running. Could be a fault if it is warm (stuck relay, broken thermostat). If you cannot get your hand in safely, point an IR thermometer at it.

Band heater on the compressor maybe?

Why not use the latent heat of fusion in the refrigerant gas in a heat pump as a better option. They come in a box, all ready to go, and integrate well with standard domestic plumbing. The trouble with using paraffin wax is not the ~150 kJ/kg of storage between 48 and 68°C, it is stopping and starting the process in a controllable way. Liquid water on the other had, may only have 4.18 kJ/kg, but is very controllable between 0 and 100°C, well actually a little higher and lower to be useful. It is very cheap as well, so cheap that in the most expensive region to buy it in the UK, you can get 1 tonne of it for £8.

Be interesting to see if the local authorities, who currently charge for household waste disposal, allow asbestos to be got rid of free of charge. Cornwall Council, through their operators would like to charge everyone that gets to within 200 metres of a dump I think. And they wonder why fly tipping happens. Still, at least it eventually gets disposed of correctly that way.

Does seem high. Can you find any parts of it that are constantly warm. Or noisy. Just to put that 200W into perspective, about what I used, on average, yesterday, for everything.

PV/T=C. Trouble is when looking at this, phase changes happen: sometimes simultaneously. This means that V and C is also changing. So. 𝛿P/𝛿T X 𝛿V/𝛿T = 𝛿C/𝛿T Or in English, as the pressure changes due to the temperature change, and the volume changes due to the temperature change, their product is equal to the change in the constant at those temperatures. This can be simplified to. (𝛿P 𝛿V)/𝛿T = C, where C is a variable for any given value of T. We can thank Leibniz for the above. Differential Calculous is the underpinnings of nature. Or just use cement based concrete, at least you will know that bit will set hard.

Yes, washing line. Costs a quid, saves 50p each load. washing machines use about 1.5 kWh (kWh is the energy, kW is the power). So using the washing machine when the sun it high is useful, though the PV will not supply all the power. Water heating is a good use of PV, though may mean you need a new/different cylinder. You may find that it is worth changing to E7/10 but the saving are marginal now over a standard tariff and does take getting used to.

Welcome. Down here we had loads of timber chalet style houses. Most have been demolished and replaces with quite naff block and render places. So good on you for renovating. I assume you are basically going to have to strip it out to a shell, repair/replace timbers and then start to put it good. The wiring will need redoing, as will the plumbing. So that means temporary accommodation. So a caravan/mobile home on the site. They can be modified and improved to make 'winter ready'. That will give you time to decide how you are going to improve the old place. Thermal improvements are going to be the hard part as done wrong, they can rot a place faster. Post up pictures.

Have you seen the older parts of Toronto? They had no planning control until the late 1970s.

Run the risk of resonance being set up.
