Air source heat pumps in the news again

[Jones82]

I'm getting so sick of the media and tories plugging ashp's like they are the solution to all our heating needs.

Latest news today, £5k grant towards the cost of replacing a gas boiler with an ashp. What a joke.

Every ashp system I've worked on and installed runs the heating at 40 degrees, great for a new build with fantastic insulation and underfloor heating but just simply wouldn't work in most of the houses in England.

Why is this never mentioned in the media?

Air source should be the last thing we do not the first, the first should be insulation and upsizing pipework.

Just think of all them new builds, built in the last 30 years with microbore pipework, some barely run on gas boilers nevermind air source.

It makes me wonder what other things the tories pretend to know what they are talking about

I think one of Boris' mates manufactures ashp's....

Yep, throw a dog a bone and they don't care who or why it's been thrown.

I was wondering about hydrogen compatible boilers in the mix for zero carbon, doesn't seem much point as the carbon reduction is fairly negligible and producing hydrogen is still mightily expensive atm. Are they really going to manage to ween folks off gas use and hope the market will take up the slack?

 

[Jim09876]

From what I understand the £5000 is not means tested, so we’re subsidising the wealthy too. What happened to Hydrogen through the gas network? This seemed much more practical from my limited understanding.

 

[Jones82]

I've also heard that the gas network will be converted to hyrdogen then gas valves changed in boilers.

I must admit, I'd assumed hydrogen burns with 0 emissions, perhaps this isn't the case.

I think the real answer lies with insulating our homes but perhaps this just isnt feasable in our old english housing stock.

The fact is most of our homes and heating systems are designed around high heat loss and high flow temperatures to compensate.

I wouldn't reccomend an ashp to someone unless it was a new build and by new build I mean brand spanking new

 

[gmartine]

Yep remember those hydrogen powered cars, the only emission is water.

Trouble is hydrogen is currently very expensive to make and I remember reading they cannot piggy back and use the existing high pressure gas pipe network because hydrogen affects the pipework adversly. In other words a new hydrogen pipe network would need to be built.

IME, they're also damn noisy. This is not a problem for commercial premises but in high-density housing it's going to drive people mad. If heat pumps are the solution then I think that ground-source units are a better bet but even these have their issues.

and when every one uses leccy the price goes up because your are stuck with it, you will need a tank fitted for your hot water, and best of all thers a power cut
no heating or cooking , we are allways on the edge in winter with supply, O and of course THE CAR,!!!!!!!
WE ARE DOOOOOOOOOMED

It’s true the gas man is doomed, we must die for humanity to live.

Over reaction Jim.

The Gas Man will take a hiatus from gas boiler installs for a period of time.

ASHP's will be installed on thousands of homes, by companies that have secluded Government Contracts to install these systems.
All tax payers will be contributing to these systems being installed.

When, in 2, 3 or 4 years, these systems become too much of an issue for the homeowner or the Goverment Funded company that installed them, the company will close or go bankrupt, leaving the home owner to contact their local Gas Man to re-install a gas boiler ( at the home owners own expense )

We had some installed in our properties, with some ugly looking, massive in some rooms radiators/covers, the after about 6 months of being in, they ripped it out and fired up the main boiler house again money well spent

Totally agree kin waste of time never gonna work in older and small bore properties

Council fitted a load up the dale, ripped them all out 18 months later as the tenants couldn't afford to run them and couldn't keep the houses warm.
Poor design, poor install and old houses, recipe for disaster.

And will the uk really save the whole world by the steps being put in place?

but the gov. knows it will work,they told use, ROFLMHO

To be honest, if it weren't so abysmally complicated, Italy's approach would be better. Here you can (theoretically) connect to biomass district heating and get 110% of the cost back (in practice you sell the stake to a bank which takes 10% so you just get a free install) or you can externally insulate/upgrade a boiler etc and get the same deal.

The problem is Italy is notorious for making the procedure so complex that you risk not meeting the criteria on a technicality, or the government pulling the subsidy when you've already spent the money. So the only people ordering such work are large firms that manage blocks of flats or whatever (effectively finance firms) that have the technical and legal knowledge to get it right, and a finger in the pie. Meanwhile the price of this kind of work has gone through the roof and the government pays... with my money.

As for the UK, Greta hit the nail on the head with her 'net zero bla bla bla'. Very easy to try the technofixes, but what might actually be more effective is if we stopped living in houses that have more than 500sq ft floor area per occupant. Of course, the problem with us having this level of discussion is that we'll never truly understand the 95% of people who aren't technical at all and rely on receiving disinterested and impartial information from product suppliers - and that, or course, applies equally to our politicians. The problem is that what we desperately need is systemic behavioural change - no more holidays abroad, massively reduced transport (actually travel less, live closer to work etc), make our 'stuff' last, and a reduction in consumerism, reduced consumption of meat (especially beef) and meat products. I do wonder if even a majority of Fridays for Future really understand that the reason 'They' are cutting down the rainforest and extracting fossil fuels is that We provide a market for it. Only then can we start lecturing other countries, but that is, of course, also essential (even if a lot of China's emissions is a result of 'stuff' we buy from them). Unfortunately, politicians of nearly all colours refuse to accept we might have to make do with less if we want to survive as a species and while the Green Party may get it, it then starts discussing things like homeopathy and possibly loses a lot of votes in the process.

Having said all that, what I've seen of humanity over the Covid period is making me feel I hope we go extinct as a species as quickly as possible and without taking too many other species with us. We're nothing special. [EDIT - bit harsh?]

The happiest and least destructive people are those with a “little life”, the old boys who live/work/play within a few square miles.

The youth laugh at them and think “they’re sad” , however their make do and mend attitude and simple domestic pleasures serve our planet well. Some have only ventured as far as the nearest big town (and they didn’t much care for that) and certainly have never been abroad on holiday.
