That could be because you live in a do dungeon. Your losses are probably greater than most.

That is pretty good. Does it still condense efficiently at that low rate?

Not sure what you mean with that statement. You will have to expand on your definition of 'current situation'.

How low can the 24, 28 and 32 kW models modulate down to? Don't think that running UFH is the same as radiators. The ability to modulate down to a few kW, and still be in condensing mode, is better than switching off and on again.

@epsilonGreedy You need to research 'contract for difference', 'strike price', 'triad payments' and long term supply contracts. It is better than speculating. It is much more than a simple supply and demand market. General note. I wonder what is happening in France with there very large proportion of power coming from nuclear, and being part of the EU grid.

Don't say a lot for the member on here.

3 of us at work tonight, I am with EDF, one of the others is with Avro, and the other, Green. Told them to take pictures of their meters in the morning so there is less argument about refunds. I owe EDF money, why I have stuck to the variable with quarterly billing. I get a lot more payment flexibility.

ICF is really a concrete house, so more time if the walls start burning to get out. SIPs uses well understood OSB, and often fire resistant PUs, but I do have reservations on SIPs for other reasons (shrinkage). Do these polystyrene houses have some certification in the UK?

Two things spring to mind. Fire Safety. Could you get a mortgage on it.

In contract law (which I doubt this is), silence is not acceptance. Always worth remembering that when your builder suggests something, then just does it without your approval.

Get a cheap worktop, cut a hole in it, then fit a normal sink. (I still remember the backache I got after staying in a hostel that had a Belfast sink, they are just too low)

It is to do with energy transfer at the cell level. Normal biological mechanisms are very low energy and can only break down a limited amount of the cellular carbon. Combustion on the other hand is a high energy process and quickly breaks the carbon carbon bonds and allows oxygen to react easily. This is why gardeners compost. There is also the issue with quickly putting in a large amount of CO2 into the atmosphere in a short time (which is what we have currently been doing for 250 years). The associated temperature rise does not fall back to the previous level in the same amount of time (to do with energy levels of electrons and the associated photon release). This is why we have a legacy problem with atmosphere CO2. We need to store, for a long time, CO2 or sequestered CO2, not just assume that we can take out this years emissions, next year. A quick reality check is to count the rings in the log you are about to burn, each ring is a years growth. Then time how long that log takes to burn. If the years it takes to burn matches the number of rings, then you are part way to becomes carbon neutral. I would like to see that log.

No. This is a myth. Most will become carbon in the soil.

It may be low carbon in your mind, but the CO2 emissions are worse than a gas boiler and now grid electricity. And that is before starting on all the other risks of timber combustion.

Not a new idea, there must be a reason why it has not caught on. Maybe frosting of modules, snow staying put, harder to install, expensive. I suspect it is easier to just fit separate PV and an ASHP.

Can you show me a gas or coal power plant that has 100% capacity factor over a year. Those are mean figures, find out the variability between different sites and different turbine types. And, it is measuring different things. The MW / MWH, against a 100% capacity factor. I wonder when this will be available and how much it will cost, and more importantly how reliable it will be I love the idea of having this, but looking at their site it doesn't look like it is going to be any time soon. There is a reason that the 3 blade wind turbine dominates.

Should not be, your imports and exports are treated differently, separate accounts with whoever you want.

Shall translate that drekly.

Should be ok. Oh hang on, aren't they in hock to the French Government for over £20bn. I am with EDF, always found their prices reasonable.

It better be with a large company that can easily raise billions on the stock market.

Old work mate of mine had an Austrian Mother. They ran a taxi company. One day she asked "vot is a vanka?

Does that make you a shining wit?

You can by adjusting the air mass flow rate. Either manually or automatically.

Yes, I forgot the 25 years ran for a couple of years. I wonder how much some companies are willing to pay for homegrown power at the moment.

RHI is 7 years, original FiT was 20 years, payments index linked and free from taxation.
