Thanks for video update and info, Adam, the effort is much appreciated. Some queries/thoughts/bollocks: (i) Boundary locating: (agree the 1m rule was stupid); yeah, hedges too 'transparent' visually, but also airflow and sound-wise. Fences, though, can be in many forms, and not necessarily airflow-solid - so the heat exchanger exhaust could still be directed across the boundary into the neighbouring property's airmass, possibly at some (energy) loss to them, especially if pointed at their house, car, ashp etc. (Similar if direction reversed, but less so.) Terrain/building topology can also be a determinant; e.g. cellar flats etc., where a 'cold pool' could form. (ii) 'Noise': Sorry, haven't read the detail of the regs and their impementation/measurement (but will soon), but assume the general SPL measurement standard is dB(a); a step-down to 37 DB(a) from 42 DB(a) is approaching 1/4 the 42 level, but is only perceived by our ear'oles as a much much smaller difference. Sound-baffling material (e.g. fencing) could remedy that 5dB(a) required performance 'increase' quite readily, given the distance separation aspect might be a limiting condition. While being a big 'green energy' supporter, wow, do i ever see some legal aggro (i.e.lawsuits) coming when some poor (?!?) Tesla driver goes out on a frosty morning to find his/her car unwilling to boot-up due to an ashp-assisted overnight freeze. In a similar way to condensing boiler flue directional regs, there may need to be more to the regs than present, especially in the relatively higher-density housing inhabited by most of the non-aristocracy. There is sooo much to this field... ATB and thanks again.
Thank you, I will reply to your points shortly. I agree could probably talk about each point for an hour or two but I don’t think anyone could handle my voice for that long 🤣 This subject probably does deserve a long form podcast.
The word on the street is ‘early next year’ this could mean anything though. Apparently MCS new standard is ready but the CPS schemes need to sign up to it too.
Do you know if the 2 ASHP for detached houses will mean you can have an air to water for heating and also an air to air for cooling? Or is it still only units for heating only...
@@RowlysrenewableroadshowOoh that's very good. I can't put an ASHP at my parent's house because they live in a terraced house. I could probably get an ASHP without planning permission curently, in my semi detached house but could still potentially be an issue. Either way, realistically they cah have an air to air heat pump because they can't exactly put a hot water tank anywhere But I could myself. It means that you can at least get your heating decarbonised even if your hot water is still fairly carbon based. But given that most of the carbon used is for heating, that's still a massive win.
Still remains at the moment, WG officials have promised change for a while. We drafted a letter to the First Minister (currently getting co-signatures from other organizations in housing/green space to add a joint weight) - DRW
I have an existing A2A heat pump and want to add a new A2W heat pump to replace my gas boiler. Can I now do this from early next year without requiring planning permission? Have you any idea of what specific date this rule change with be effective from. Can I press ahead now for an install in say March 2025 confident I will not be required to get planning permission. Thanks, I would appreciate your knowledgeable response to my questions.
Why in this country do we always have to have something outside the goverment to set rules. All these extra layers of rules just put the cost up to get things installed and in my experience especially with heat pumps does not guarantee a good job. I have seen many that I have been very poor, oversized heat pumps undersized pipe work even one where I had ti re pipe it as it was that bad they had even left 6 metres of 28mm pipe outside un insulated as the customer couldn't see it as the heat pump was on the garage roof. Not impressed with what I have seen dine by so called MCS approved installers. Does it stand for Makes Costs Skyrocket!
You’re preaching to the converted. I agree the layers of schemes add cost that is ultimately passed to the consumer. When I chat to German and French colleagues they can’t believe what we have to deal with.
@Rowlysrenewableroadshow best to just carry on regardless I fitted my own at a cost of about 6k for a 16kw Samsung. Hot water cylinder was OK so just had to up some radiators. Completely happy with it although a 12kw would have been big enough I think

Another good one Adam!
Cheers John 👍
good video - as changes are England only thing, wasn;t aware of the change is size and the relationship on noise. Excellent insight. DRW
Cheers, yes my wife said I should have made it clear it was England only.

@@Rowlysrenewableroadshow yes please 😵💫
It’s about time, just wonder what the welsh government gets up to.
We will have to see, hopefully they will follow suit….
When do you think these rule changes will come in?

Air to air was included under the heat pump umbrella for VAT relief purposes a while back so I would expect it to be included in this.
Hi, yes MCS did state a2a will be included.

Is the 3m boundary rule in wales going?

A friend has two neighbours who have installed heat source air pumps and the noise is causing her stress, particularly at night.
But they hardly make any noise
She's had them installed poorly then and should get a different (competent) installer back to rectify
That’s a shame, what make are the heat pumps?

Hi, no date as yet. But in theory yes you will be able to do that.
No promises on the date yet.

Oil tanks are not allowed near combustible boundary
Yes, you are right
my next-door has 2 tons under a large yew tree. (adjacent the boundary) - now THAT's 'combustible'!
