Heat pumps and noise

[diy_fun_uk]

I live in a bungalow with (mostly) bungalows around me. The properties are all detached but relatively close to each other. My bedroom is at the rear of the property. When I'm in bed at night it's totally silent. Bliss.

I sometimes wonder if this nighttime silence would be maintained if any of my neighbours opted to get a heat pump. The logical place for them to be installed would be at the rear of the properties i.e. where most of the bedrooms are and back gardens all back on to each other. I've read good and bad about noise generated from the external unit, especially if these aren't properly maintained. Even when they are, some still say there can be annoying hums emanating from them.

Does anyone on here have a heat pump or a neighbour in close proximity who has? And if yes what is the noise like at night? Some of the comments below this article make for interesting reading, with many citing noise as an issue.

I have this picture in my head of streets that are quiet at night, gradually becoming 'hum zones' if more and more get heat pumps installed as part of the green initiative drive.

More homes to get £7,500 heat pump grants from Government £325m top-up

The Government is putting more money into the Boiler Upgrade scheme which gives grants for heat pumps - as well as scrapping red tape around the green devices.

Like EVs, if heat pumps were any good or really for our benefit, governments wouldn't need to force us to have them.

However, if polar bears have to be saved sacrifices need to be made.

These are the best. Soft, comfortable and block more noise than most.

We had a similar situation in Australia, quite a few houses had aircon in the bedrooms and the outdoor units used to start up at bedtime, got used to it after a while

Yes my thoughts exactly - those things have a massive fan in them. But that's why in-order to get your £7500 grant you will have to have it controlled externally - smart style and they can just turn them off remotely - say at midnight.

Also the 1m regs are being thrown out for them so people will be installing the as far from their own house and right up next to next door instead.

Why would anyone want to spend £12k (5k with the grant ) to save £100 per year

Exactly - also if man is causing the world to "boil " as we are told then world governments would supply its citizens with EVs and heat pumps and solar at no cost. But instead its - we need to save the world and all we need to do it is your credit card number - its a scam.

Very simply.

Where would the world governments get this money to supply things at no cost ?

they would obviously need to pay for factories installers ECT but for that they just create the money with a button -world wide governments all doing the same.

As said it's an out and out scam. Same as the covid scam and the EV scam. The people need to put a stop to these things but we will blindly bumble on following a bunch of clowns that know nothing. I live in a bungalow with a gas boiler (Worcester Bosch standard boiler). My central heating is 8mm microbore. My floor is concrete so the pipes for the rads all come down the walls from the loft as do the hot and cold water pipes. It would cost way way more than £7500 or whatever it is to change me to a heat pump. Then you have the noise and they are very noisy because the government (LOL "government" bunch of f*****g idiots more like) are in the process of, or have already done it, increasing the upper noise level limit because of the noise these things, that do not work anyway, make. You really couldn't make this ****e up. Thankfully I'm old so I don't have long to go but I wont be fitting heat pumps any time soon.

Yes, whenever the government mentions net zero targets or some similar bs, you know they're going to use it as an excuse to pick our pockets or curtail freedoms. Often both. But the turkeys who follow all this to the letter won't even hear that they're being taken for mugs.

Government is completely schizo on all this. One minute it's sell more ssh!te, buy more ssh!te - we need you to consume more ssh!te to keep the economy going. Next it's panic because everyone is using and consuming too much ssh!te and they're saying it's bad for the environment. They need to make their minds up, do they want a red in tooth and claw US type economy or not.

Same with population. Government are always banging on about using less electricity, gas, coal, plastic, whatever. So what do they do. Deliberately import millions from the third world to swell our population so that all these incommers can enjoy a decadent western lifestyle - using more electricity, gas, coal, plastic, etc, etc. So why should we worry about using less resources when the government are intent on the country using more as a whole by adding millions of consumers to UK population. But still the sheeple follow every word and diktat of useless, corrupt and trecherous politicians. It's like they can never see what's going on. Or don't want to.

A solution that doesn't work for a problem that doesn't exist.

Over 30 years ago I visited my aunt in South Africa. While we were there we went to Kruger Park. The accommodation was in small, individual, very basic rondavels (small circular buildings with rendered stone wall and pointed thatched roof consisting of a bedroom, bathroom and kitchenette). At night it was still quite hot so I put the ancient wall mounted ac unit on. Lying awake in the dark with this thing clanking away, it was impossible to get to sleep. After an hour or so I turned it off. But then the temp rapidly rose so now I couldn't sleep because of the heat. Went on all night like this trying to get it cool or quiet enough to sleep. Since then I never travel without ear plugs.

The interesting aspect is this
Most heat pumps are designed to heat water (to run your central heating system) to 45-50°C and domestic hot water is used at 38-42°C.

Radiator systems have been designed to run at 80C but some may have been done for 60C. The lower the temperature the larger the radiator area needs to be. Water flow rates figure as well.

The pumps
Air source heat pumps are highly efficient heating systems, capable of producing more energy than they consume. The efficiency of an ASHP can be measured by its Coefficient of Performance (COP), which is the ratio of heat output to electrical input. A higher COP indicates a more efficient system.
Depending on conditions, ASHPs can achieve COPs of 2 to 4, meaning they produce 2 to 4 units of heat for every unit of electricity consumed. This high efficiency is due to the fact that the majority of the heat generated comes from the ambient air, a free and renewable energy source.

So if a uninsulated house is ok with 30kw output gas boiler would it be ok with a 15kw heat pump? I don't know but wonder. A house shown on the TV that had been converted appeared to have a hell of a lot new piping installed.

Ok. I'm off out to get the tinfoil
