Anyone thinking of installing heat exchange pump for central heating...think again

There's drawbacks/issues to come from all this sealing up and air tightness it just hasn't been around long enough yet.

My house is 16year old and has damp corners because it's too sealed

My coldstore is airtight, when it's full of potatoes I'd say that if you were locked into it, there wouldn't be enough oxygen to do you till the morning

I wouldn't want a fully sealed up house. I don't live in Finland or Canada and I don't like living in a house that is perpetually hot. We lived for 13 months in a brand new rental property and it was a living hell in the summer because even with every window open the house retained heat like you wouldn't believe. The guy near opposite us worked from home and driving by the other day I see has had an air conditioning unit fitted to the wall- what he has gained from modern insulation has cost him now to cool that one room he sits in all day. Ironic really.

You are so right Ollie even in the winter living in a very well insulated house I keep the bedroom window open. Without it I am very soon coughing. It is ludicrous and was the number one health control measure the Victorians brought in.

You know people could also wear some winter clothes and wear more than a buckin’ TShirt and slacks whilst complaining it’s cauld

The grid does not run at full capacity all-day every-day.

Overnight there is about 20 GW of generating capacity that gets stood down. It will be this capacity that gets used to charge folk's cars, it won't be during the day.

Even at 20 pence a unit, electric cars cost virtually fudge all compared to fossil fuels. 20 pence a unit is £200 per GWh and believe me you could build a dozen Hinkley C's for that kind of money.

Did you get a government vaccine supplied by idiot BORIS, years ago i has my electric meter changed to dual rate as it was cheaper as you state at night but guess what my energy supplier moved the goal post's so to get a cheaper night rate i had to use more during the day, then they wanted to install a smart meter all because some crank of an MP had worked out how many tonnes of carbon we could save their ar-- must be sore because that is where i told them to shove it, also as some else stated wait till everyone is charging batteries then find out what will happen, our government is led and staffed by people who years ago would be in a lunatic asylum.

The guy who installed our solar thermal panels(which are brilliant for heating hot water) , nearly went bust removing useless air source heat pump installations fitted by him!

Anyone put any prices on the cost of heating a modern well insulated house with a heat pump?

Electric cars will work. One of our near neighbours has a tesla model 3. Gets him the 30 miles to work and back, changes via lead under the garage door. It's no big deal. Won't work for all but the average annual UK mileage is ridiculously low. For tractors, plant and 4x4s you can just use HVO as a drop in and then methyl esters once true synthetic fuels are online.

The bulk of this forum could buy HVO and run their diesel engines on it right now with no significant changes to their operations.

Ditto heating oil- a renewable version of this exists or could be formulated. Household kerosene is a lot convoluted a product compared to road fuels.

If you have a fatty-acid, then HVO is a much better solution than esterification. Its unlikely that we'll ever see e-MeOH to OME, as it's not a great diesel alternative and there are much higher value uses for the methanol. The first synthetic FT plants will be online in a couple of years, they'll be worth watching.

The most useful near-term solutions are all based on co-processing, using waste streams to create a feedstock for a conventional refinery. Then the slate of products (the balance of gasoline, kero, jet or diesel) is primarily dependent on demand/margin.

The only thing we can be sure of is that there's not a cheap solution.

Take away the cost to put our systems in which will be paid for by the RHI & the cost heat our house is 0 over a year with the electric we export it makes money not much but it cost nothing how long it will all last is a ?

A friend has just taken out his ground heat source and put in an oil boiler for less than a repair bill which was needed and his electricity bill has dropped drastically

My dads house was built in the late 70’s despite being cavity block built my own 150 year old house is definitely warmer, probably due to being dry lined and insulated in the late ‘80s.

It’s surprising that some homes could be under 20 years old and still quite poorly built.

Building regs are a minimum standard most house builders aren't gonna spend money they don't have to.

Regs should be better then? Once was a time it was 4 inch cavity, now near everything is 6.

….and even self builders are on a tight budget usually!! Not to mention not knowing any better at the time. They pay for it later in fuel though…..fuel is many times the price is would have been back then.

I have a 3300 sq two story house build 14 years ago , I have underfloor and a ground source heat pump, I insulated the house completely to a very high spec , the house is zoned so we can increase or decrease temp in any room separately . My wife and kids love heat so the stats are set at 20 degrees all the time , the house is always lovely and warm , it’s costing €3 a day during the winter to heat.

Take tonight for instance all the wind turbines are in shut down as the wind is too strong it's freezing in most places and there is an almighty windchill. What would the green future be tonight without gas and coal powerstaions and oil or gas fired central heating?

Shocking! He probably didn't anticipate the rise in his oil bill though! yes, changing from electric heat to oil will lower your electric bill.

Heat recovery ventilators have been around a few decades by now, the argument for a drafty house has been lost. You're still allowed to open a window too, the difference is you open a window when you feel like it, and close it when you feel like it, instead of having the whole house leak year round, whether it's blowing and cold, or hot and muggy, or just cool and damp.

Barely all the turbines we are currently generating 27% of our power using wind tonight

It is clear that HVO is only a solution provided you have a green feedstock. After that, you're back to making fuel from scratch using carbon from the air and hydrogen from some kind of serious process heat.

What % of turbines are working?
