That is a good thing, it reduces the spinning and hot spinning fossil fuel reserves. It is better to close down a few wind farms that let a large gas plant be shut down. The restart costs are to high both financially and environmentally. Luckily we don't have much biomass and OCGT units running now.

How old were your modules. If a few years, for a lot less than the original kWp price you, you may have been able to upgrade to more efficient ones. Does depend on what they buyer of your house thinks about them. I would think at the moment, and till about May, PV could be charged out at a premium. Come June, we will have all forgotten about today's increases in electricity prices.

Anyone hear the R4 interview with the woman about her energy prices. Hardly a typical person.

I have been saying this for a while now. The difference in day and night prices has been eroded over the years. For most people the price difference between a fixed tariff and a flexible one has been similar, as long as they use 70% at the cheaper rate. Even at my 80%, my unit price has been about 16p/kWh. Not so different from what a lot if people were paying anyway.

Time will tell.

Going to be fun this is. 60p/hour to run a fan heater.

Assuming it is grid connected, and you have the appropriate inverter and safety isolators, what does your local DNO say about an increase in capacity?

Pumps and valves may be indoors. They make a noise. You get clicking, popping and gurgling from most CH systems in my experience. None are silent. I can hear my immersion heater when it is on.

They do a similar thing with E7. The day rate is higher than the capped rate. But overall the price is still cheaper for me.

Some buyer will pay to have them taken away. The big cost in decommissioning a system will be scaffold hire.

What about non DD customers? After a quick scan I cannot see it.

I am so looking forward to seeing what happens. Can we have a Sweep Stake.

Whoops, missed a 1 at the beginning out. I hate typing on my phone.

Do you know your airtightness numbers?

Or 600 quid if on gas. They are letting us know tomorrow morning what the new rates are, and how they are going to subsidise the increases.

SCoP may be higher than 3, does depend on your climate and how hot you have the house.

That would be if you were heating purely with resistance heating. Divide by the sCop to get the electric cost.

Better to oversize. Do you have a SAP that shows the heat load, or run it through Jeremy Harris's spreadsheet.

That is the thermal energy needed to keep your house warm, it is irrespective of the technology.

That is to cover the 99th percentile. Almost any heating system will be designed to supply enough power, 99% of the time. That 1% us for extreme weather events i.e. -18⁰C or something. Most of the time a 6 kW unit would do your heatload quite happily. There is a bit added, 2 kW, for heating the hot water. So seems to be about the right size.

Roughly 100 kWh/m².year. Or assuming 5 months heating, 25W.m² power needed. Do you have any other heat loss calculations?

Sounds like something derogatory from Geordieland.

Me too, why I am in St.Ives.

If you had read some ASHP topics in here, you will have read about buffers, and the most economical way to run systems. But you haven't.

La Nina years can be more unpredictable, but there are climate models that show that an increase in overall temperatures will push extreme weather events further north and south. It is really a matter of where the air cools as to where the strong winds are centred from.
