17 MWh a year does not sound too bad. I use between 3.8 and 5 MWh a year depending on how cold the winter is. And there is only me, in a small house. So if there is 4 of you, and your house probably has 4 times the area, or more, than mine, and you have a pool, just pay the bill. 200 W of LED lighting seems excessive mind. My whole house only has 30 W.

Just a matter of basic data collection and statistical analysis. Bread and butter stuff.

It is always hard to compare, as you cannot easily build an identical house, subject it to the same weather regime and see what the difference is. But you can run the DHW on pure electrical power for a few days and then look at the household data and see if there is an overall difference i.e. does the space heating requirements go up. I can hear my water heating up at night, and that is the most basic of systems, just a 3 kW element in the bottom of the insulated cylinder.

Energy cannot be created, it can only change its form. So if you suck energy from one place, to keep things in equilibrium, it has to be replaced. So taking energy from the airing cupboard, just means that excess energy has to be put in there initially. So you need to know where this energy comes from, in what quantities and is there a real benefit.

My fridge is very quiet, and hardly comes on anyway. Worked it out that it has an average of 5W usage, considering that the motor runs at 120 W, that would only be 1 hour every day. Get a new fridge.

If the new ASHP, that is heating a fairly new built house is noisy: It is sized incorrectly Is an old design ASHP Is damaged/broken That would need a lot of unpicking when it comes to energy conservation. Though the noise may well be acceptable, that is easy to check with a meter.

One of the cheapest places in England, staff costs are the same, why we have minimum wage. Boris will fund it, he has already said so.

Do you mean the circulation pump for the UFH\radiators or the one that pumps fluid within the actual ASHP (depends on design). While not desirable to have the circulation pump on all the time, it does even out the room temperatures.

That is always the case. The RHI was really set up so people that were using oil or non-mains gas had a viable alternative. it was never meant for low energy new builds or renovations. The idea was that it should be cost neutral, not to make a 'profit', but in doing so it should reduces the overall CO2 emissions. That final point is often overlooked.

Did you call them felch by mistake.

On the admin side of the MCS. It is not cheap to be part of the scheme. It is a bit like having your new car serviced at the main dealer or Honest John under the arches.

It is supposedly the same down here. The answer is to get people that want to buy houses onto the local council and change the interpretation of the planning laws. They may build more houses then. As it is at the moment, a couple of towns have effectively stopped all development because they do not allow building of holiday homes.

Not many. But it is a good way to keep the public swimming pool clear of people.

The use of chlorine in food processing is common practice. The EUs 'problem' with American chlorinated chicken is to do with animal welfare standards, not the post production after slaughter.

I think you need to exclude results from Urban Dictionary

I was thinking of buildings. So about 1.6% (400k / 25,000k *100 = 1.6)

Hope not as you are in a different country.

I think the guy at this house must have been upset when an arrogant architect moved in next door and put the roof extension on. It is a 'look at me' house.

Just hope it works. Have you thought about adding some solar thermal for the pool? Quite simple to DIY it. Did it for my parents pool back in 1984. Worked well.

£2bn at 5k a house is 400,000. So just over 10% of the stock. And most of it will be substandard. If the use the existing MCS scheme to fit heat pumps, at best it will probably only cover half the cost. I personally think that just fitting PV to suitable houses would be the most cost effective method as it displaces fossil fuel use. But that is not what the scheme is set up to do, seems it is to reduce individuals energy bills. Realistically it is just the Green Deal repackaged.

12% smaller, so assuming that all things are equal (they are not as the centre of the fan will be a similar diameter), you have lost an 1/8th of the airflow, just when you need it most.

Smaller fan diameter will cause less airflow though the element. So more time for frosting up to happen. Have a look at where it starts to freeze up first. Probably where there is little airflow.

The way I understand it is that the oil part is comparable to the resistance heater in a regular ASHP. So if sized correctly, the ASHP does most of the work with the oil burner just being used for boosting DHW temperature and the occasional times that the ASHP is unable to deliver enough space heating. Seems a lot of hardware for little work. But I suspect the ASHP element is used to tick an 'environmental' box is too small for most houses.

With your new bridge supplying 5.1 to each room, all opperated from your phone. Did the speakers make a chuckling sound when the door unlocked. On a more serious note:
