You can use an IR thermometer if your aim is good.

My house is a similar size to the OPs flat (48m2). I do my laundry at night, and I sleep though it. How much do you think you use during the day? I work evenings, only use a couple of kWh during the day, and often less. 80% of my energy is at the night rate.

Almost there then. https://www.engineeringtoolbox.com/heat-recovery-efficiency-d_201.html

Yes it will. The majority will be generated via renewables and some new nuclear. This should not come as a shock to anyone, it has been discussed, like Climate Change, for years. The people that need to do the work, not small builders and householder, but the infrastructure providers, know what to do, how to do it, and when it has to be done. None of this is an idea that popped into Boris Johnson's head last night. I also heard them talking about fuel poverty on the radio earlier. This really does need a proper definition. Many people still work on 10% of a household's wage. This is a nonsense number and was plucked from thin air I suspect. I am going to claim that most households are in 'vacation poverty', 'transport poverty' and 'gambling, fags and booze poverty'. I base that on nothing that prejudice and ignorance. But as a nation we are certainly suffering from 'educational poverty'.

Are they talking about doing proper heat load calculations? And why the (expletive deleted) are you listening to Radio 2. That is for people that are stuck in the past.

It is about time we got @DamonHD to have a word with his father. He used to combine entertainment and fact quite well.

Be wary of IR heating. If it was so brilliant, we would not have panel and fan heater. Have you considered storage heaters, they have moved on since the 1980s. Maybe discus with landlords again tell them there is free money to be had.

Or a terminology one, they should be called convectors, not radiators. I do hope that science lessons in schools start teaching this stuff, it is all very simple, little mathematics needed and could make a huge difference.

Been discussed, quite badly, on R4 all morning. Left a program about COP in Glasgow as it was not saying anything new. Regarding MCS taking the £5k as a 'bonus', it may spur others on to do a 5k system. It puts a price on things. You can now get PV installed for a quarter of the price than 15 years ago, not all of that is down do lower module price.

No. But I know my energy load could be very small at night, sub 1 kWh/night. If you are going off grid, demand reduction is the key.

Check it, and maybe get extra cover. Don't mention when your neighbour came around.

Are you/your builder insured?

Think it is better to start a new thread about this. This is about people venting off their frustration about government policy.

Don't it work because it takes time to charge up the capacitor, this is what shifts the phase. I take it that the capacitor/s are after the transformer/s. Can you work out the RMS voltage?

So glad I did not rush out and buy a telly then.

It is based on the reheat time. Any heating system will take a while to start producing thermal energy at the desired temperature. Once at that temperature, and assuming the set up is correct, maximum CoP will be delivered for the conditions. So basically it is ((stored energy + added energy) - consumed energy) / time. So you need to work out those to get s volume. No need to go to 3 decimal places, nearest kWh will do.

Built some professionally. Not as simple as they seem. Copy a Proven WT6000 Or just buy one for a quid a watt. https://www.hitwind.com/product/proven-wt6000-6kw-used-wind-turbine-for-sale/ If you have the room, why not PV and some storage. Simpler and easily scalable. Not sure if you need MCS to get payments now. Think you can deal directly with the energy companies.

I would still fit one. You are assuming that there will always be enough water volume, at the right delta T, to make the ASHP function as intended. Higher than needed return temperature, or too low a flow rate can also throw an error that stops the pump.

If you park up in The Swan Theatre short stay carpark in High Wycombe, they have a similar finish on the stair well wall. Has an interesting odour, piss and detol. At least down hear they only smell if pasty and fish.

Now the stairs are in, how are you going to render the walls?

It is to do with the reheating time versus the heat loss time. If the time difference is too short i.e. you are only heating one small loop in the system, say it is spring and the kitchen door is open because you are gardening. Then the losses will be relatively high, but the input from the ASHP will be much higher. This will cause the ASHP to switch on and off quite quickly. That is not good for the CoP and not good mechanically for all the components that have to switch on and off.

What is the smallest volume of water that the ASPH can deal with? Then make it larger.

Think we need a bit more information. Got a link to a report or product?

Just lift s few tiles and poke them in. Climbed a slab near St. Just. About 50 m high. Top 2/3rd had nowhere to put in protection. Pretty scary that was. Did see a sunfish from the top, so worth it.

@joe90 This is all we use, can usually find somewhere to wedge one in.
