Thanks, great video, it fills me with confidence knowing that there are people like you trying to build things up when the mainstream media are trying hard to tear things down, keep it up.
Great video, and some interesting insights, especially the things about MCS, and how to handle things in future. My only (minor) gripe is the comparison at around 21:20. Where because leccy is 3.5x gas, a heat pump needs to achieve a SCOP of 3.5. It works in simple terms, but for most in the UK, gas boilers are likely (according to OVO) running at about 84% efficiency. So to break even with gas, a heat pump would only need a SCOP of 3. Obviously, every system is different, and I haven't seen anyone doing a proper test in actual gas efficiency in the same way openenergymonitor has been used for heat pumps.
@@BenIsInSweden absolutely and if I did a deep dive into that subject at 21.20 I could probably bore everyone for another hour 🤣 but yes I agree gas boilers are iro 85% efficient at best so yes your comparison is probably more accurate. Thanks for the positivity 🙂👍
I think the real issue facing most people is the cost, even with the £7.5K government subsidy. I've paid for a full MCS survey, heat loss equating to need a small 5KW unit, no radiator upgrades required and yet still £4,200 to pay. I want to switch to a heat pump but the installation costs need to come down.
Just watched your video with interest, had a verbal estimate for heat pump to replace a ageing combi. £15500 for a heat pump £2000 for a replacement combi, is someone having a laugh😂
One verbal estimate...? I had 2 estimates... 1 at 18000 and one at 11000, both with heat pump grant off and both for an entire wet system as no rads installed. Get another quote.
Compared to air-to-air heat pump systems, air-to-water heat pump installations appear to be so much more complicated, bulky and possibly more expensive to fit. Most owners of smaller houses, after 20+ years of using combination boilers, will really not want to see the return of a hot water tank. "Needs must" and all that, but really not wanted.
excellent commentary with a lot of spot-on observations - really glad i listened through - thank you for posting and best wishes for the business. Appreciate if this seems a bit cheeky (have i just caught this vlog but missed a whole string of them?) but you could do the industry a big service here - and perhaps achieve more than our governments have over the last 15 years - by, maybe, making some follow-ups on such things as, e.g. the difficulties presented with most uk (especially post-80's) housing stock where space and/or structural capacity for a water-tank/thermal store has not been allowed. Also, maybe how 'smart' (electrical) power supplies an/or solar pv and/or domestic batteries and/or v2g/h/l ca all influence running costs and will do so increasingly in the next few years. Maybe also a 'this is our experience...' of measured noise levels at actual installs, where surrounding materials (and obvs the heat pump itself) give a real-world measurement (If smart electricity is the way we are going, then having neighbours griping about 'some whirring noise at 3 a.m. from your bl***y heat pump...' is something the installation industry doesn't need - but the energy supply industry does (!))

Really appreciate your positivity, in answer to your question I have been talking about heat pumps face to face or as a public speaker for years now.

Why aren’t ATA systems available from the government grant scheme? I would like to get rid of my gas boiler but looking of what’s available the ATA heat pump would suit my needs better.
@@KavanOBrien a2a are a great option and work well. The reason why the government don’t support them is a2a can cool, bringing a cooling option into a British home is a luxury and in most cases increase a house electrical consumption and therefore c02 emissions.
@@Rowlysrenewableroadshow Really wow that seems bizarre , why can’t the ATA system have the cooling option disconnected as an example or have ones that can only heat and not cool , if the main concept is to have the gas boiler replaced then I think the government are limiting themselves, many people I talk with would get rid of the gas boiler if ATA was an option not ATW , ok then unfortunately looks like I have to get a new gas boiler then , didn’t want to do that but ATW is far too expensive to run , lots of people who got ATW wished they hadn’t after finding out when they got the bills from the electricity companies.
@@KavanOBrien that’s a question for government I guess, potentially you could disable the cooling function. As far as run costs and a2w are concerned a well designed system will be cheaper to run than gas. And yes for some and it sounds like you a new gas boiler makes fiscal sense as it stands, however be sure your gas fitter designs any replacement rads to low temp as that is how you get maximum efficiency from any heating system including a gas boiler, then down the line a heat pump could easily be retrofitted on your system.
@@KavanOBrien For A2A, removing cooling means you're removing over half of the functionality (cooling and dehumidifying), and likely if something was done it would be something that could be "modded" back in, as A2A units need to be able to operate in "cool" mode for defrosting, so there's no hardware limitation. A2W on the other hand, cooling whilst possible, is far more complex - needing fan coils/ufh or an air handler instead of radiators. A2A you're provided with everything you need for cooling. IMO I would definitely forego the grant over having cooling disabled. I don't see it happening, but if consumption and CO2 emissions are the primary factors, then having solar (and enough capacity) should negate those for any sort of grant, as the net effect essentially becomes zero (i.e. the heat the solar panels have absorbed counters the additional heat output from the external unit). It being a luxury I can sort of get behind, but how many people have been hospitalised/died in the UK when there's been heatwaves?

It was built in 1912, three bed semi with loft extension. I filled in a rudimentary questionnaire, received a phone call with that £15500 price.
