Brilliant John, love that. It just shows how important these experiences are for people when young. Have you been back?

Thank you David, We have had our Kia EV2 for almost 2 years (end of August), I still absolutely love it. It is so much easier to drive than a conventional vehicle. With your charger can you get Octopus Intelligent, which gives you electricity at 7p instead of 28p. I would just check that the charger you are installing is one of the ones Octopus can help manage for you giving these very cheap rates. The Octopus web site lists the chargers that it can work with. Thank you for commenting, I really appreciate that. Did you see the first 6 weeks video? czcams.com/video/WlTpOacEodM/video.html

Wow ...... Thank you. I am really pleased you enjoyed me coming to grips with my first electric car. It is still going strong and I still love it. I plan to do a two year video of driving an electric car later this year.

I am not sure what you are referring to. Battle of Killiecrankie was 1689, Act of Union (of the Parliaments) creating the United Kingdom was in 1707.

@JamesRattray I apologise you were correct I was thinking of the 1715 uprising. My bad 🤭

Thank you - The deareator is located by the hot water tank and it is on the flow (incoming) pipe. It is located before the three way valve which diverts water to the tank or heating as required.

I filmed at the time so it was in the frame. I wasn't trying to trick you. It is at the bottom right at the start, look at the leaf and soil. I think part of the problem is the camera and probably our eyes focus on the vegetation, obviously the tiger very cleverly uses the vegetation as a screen to hide behind, We saw a leopard doing the same thing at another park, the leopard successfully killed a cheetal deer.

What I found absolutely staggering, is neither Kia UK HQ, nor Kia Wessex cared one iota. I don't want to post videos about abysmal customer care for a product I bought. I had hoped from some recognition (verbal or written, not monetary) that things had gone wrong. KIa HQ said its a franchise and we can't do anything. I don't believe that for one minute. Can you imagine McDonalds HQ the burger people, saying that about a franchisee. Also Kia Wessex never tried to contact me, discuss what went wrong. I gave them ample opportunity. I decided to publish it because I felt I had a wider duty of honesty to people buying Kia and in particular that Kia dealership in Newport. So sad. If they had dealt with the issues honestly I would have mentioned them briefly with the successful conclusion and not posted everything.

The heat pump is a Vaillant 7Kw which is capable of 9Kw output at -2C. The maximum pump pressure is 80KPa, the maximum flow rate is 1200ltrs/hr and the minimum flow rate is 650ltrs/hr. I managed to find a copy of the pump curves. What are the figures for your secondary pump? How have you measured SCOP? The data from my Vaillant heat pump overstates COP by quite a high margin so I use the data from the open energy monitor instead.

@@hughrattray9354 Thanks! Pump pressure is a little confusing. 80KPa is 0.8 bar but my primary pump has a max pressure rating of 10 bar which seems like way more than enough to feed the whole system while barely breaking sweat! I wonder if it's possible to calculate the theoretical pressure drop across a 16 rad/8mm microbore network?

@@lumbarsupport I did work out the pressure drop through my system using John Cantor’s tools for pressure drop (details are in the video notes). He has a very handy tool that allows you to vary flow rate and pipe diameter. The pressure drop across the radiators is very low (0.2kpa). I calculated the overall pressure drop across the system to be 20kpa. I have 22 rads and 10mm microbore.

Thank you for taking the time to let us know. Stuart put a lot of effort in to this using his many years of experience. I was the cameraman and editor, I too found it fascinating.

Thank you. Your comment is much appreciated.

Because the red coats soldiers were all Scots, except for one under prepared English Regiment, called Hastings, every other regiment fighting the Jacobite were Scottish red coats. You have to remember the Jacobite wars were Scotland's two societies, Lowland English speaking culture versus the Gaelic or Highland Culture. The Jacobites weren't just Scots, there were English, Welsh and Irish Jacobites a plenty. It was a civil war, supporters of one Monarch Catholic King James VII verses Protestant William of Orange who had been invited over by the Protestants.

My installer was Swift Renewables out of Clevedon, Somerset. I am happy with the work they did and have recommended them to others.

I am Octopus Go, 9p currently will be changing to Intelligent when we move to our new house. I still love the Kia, if anything even more, as I get to EV thinking as opposed to diesel vehicles. Enjoy your purchase.

Very interesting, thank you for sharing this with us. We are always keen to hear heat pumps are evolving in other areas of the world.

Very happy to accept a different view. Batteries are continually evolving and I believe newer batteries will not be so harmful to the earth's resources. Keep enjoying your EV as I do too. Thank you for sharing your thoughts

My journey to the heat pump installation took place over several years and included additional loft insulation (minor improvement) and new windows (massive improvement). I observed the house heat loss using a borrowed infrared camera to check for hot, leaky spots (I still have an area I need to improve). I also assessed the heat loss using the "Heating Degree Day" methodology and in-room calculations based on the construction and window thermal conductivity values. Finally, the EPC assessment was done and this confirmed the house was well enough insulated to get the best out of a heat pump (it got a high B).

Thank you for highlighting this. According to the Government website, in order for your property to be eligible to apply for the BUS, you need an EPC with no recommendations for cavity wall insulation or loft insulation. This is a quote and link to the GOV website "Your property must have a valid Energy Performance Certificate (EPC) with no outstanding recommendations for loft or cavity wall insulation. with no outstanding recommendations for loft or cavity wall insulation." Apply for the Boiler Upgrade Scheme: Check if you're eligible - GOV.UK (www.gov.uk) When Ian was saying this, I did put a caption on saying check the Government web site out for info. But you are right, Ian's interpretation was not as above.

It’s now changed……. And it was never that it had to be a ‘C’……

@@deanchapple1 I had the C requirement in my head. In retrospect it may have been an installer who mentioned that they wouldn't install a heat pump in a house with anything less than a C.

I would agree with that. What period of grace do you get from end of charge to being charged. I would think 15 mins maximum, especially if you are going to prevent some one else accessing the charger.

That is interesting. From looking at one charge station only, I saw Tesla were charging 49p per kWh when the opposition were charging 79p. So I will definitely have to get Tesla charger App on my mobile for my next trip. Thank you for that.

There are two good examples of microbore systems working well on this channel. One with a buffer tank and the other without. The key issue is to make sure you have adequate flow rate. Both the systems here have 22mm backbones with 10mm radiators plumbed in parallel to each radiator.

@@hughrattray9354Not really the most important thing, 10mm has a limited Heat Carrying capacity, so it’ll limit the size of the emitters. Which for a Low Temperature system is not good. Also, regardless of fitting a buffer or not the F&R Delta T is very important & again with 10mm tube, it’s limited.

@@TheDickPuller I have an 11.2kW ASHP with 16 large radiators all using 8mm microbore and it works extremely well. It uses a small low loss header in 3 port config, with the microbore circuit supported by a secondary pump, the return bypassing the LLH and connecting directly to the primary return. Average flow temps rarely get above 40degC and COP average for Oct'23 to Mar'24 was 4.2, for heating and hot water.

@@lumbarsupport Has s your CH circulation pump running like a Steam Train too??!!! My guess is the circulation through these Microbore tubes are a huge velocity!.......These circulation pumps will not last very long. Plus, you must be telling Porkies, as your figures don’t compute. So don’t talk 💩, I’ve been in the CH game for 50 years & you beard stroking, tree huggers talk drivel! Just listen to the two old farts in the video, Sanatogen Sid & TCP Pete😂😂😂😂

Change always causes controversy.

@@JamesRattrayindeed, especially when it’s change for the worse

@@mikeolly67 When the railway reached Stirling in Scotland, church ministers ranted from the pulpits, there were riots in the street, famers believe their cattle would die from fright. Today's change is EVs. I have owned one for 18 months and would not go back to ICE vehicle. It's always good to have different views on a topic. Thanks for your comments.

90% of my charging is done at home. I only need external chargers if I do a round trip greater than 200 miles. So I would say comparing it to vehicles using petrol pumps, the EV chargers are used one tenth of the volume. Where EV vehicles need the chargers is at motorway Service Station car parks and places where we need a top up. Definitely slow chargers at Travel Lodge, hotel accommodation. Our self catering host in Devon let us charge overnight with our 3 pin connection charger. So easy to do. Thank you for your comments.

My heat pump is completely silent inside the house and very quiet outside by the heat pump. Because the flow temperatures don’t change a lot I don’t even get the ticking noise due to thermal expansion. I think there must have been something wrong with the installation you visited. I suggest you search “visit a heat pump”, a lot of us have offered to show people our installations so you should find some close to you that you could visit.

The DNO now restrict how much you can export and this must be implemented by a G100 compliant limiter but they are also now restricting your total inverter capacity. They will count the inverters for your solar system and also the inverters in any AC batteries you own. I am not sure why they are restricting total inverter capacity. You can implement as many DC batteries as you like.

Most of the old radiators were either Type 11 or 21. To achieve the power output they all became Type 22 (apart from the towel rads in the bathroom) and we used taller rads (in every room we had space for this). Aside from some tidying up of the pipework around the radiators they all fitted into the same width. The maximum output from any rad is 855W.

I wonder why heat pumps modulation range is not greater - do you know? The Vaillant can run at a minimum of 25% of output. Why can't it run at 10%?

For those who did not do such an install he showed a middle finger

90% of EV charging is done at home. It's the long journeys I look for a charger. I don't understand why the pricing and display structure is different to fossil fuel pumps.

@@JamesRattray I agree. There is no reason they couldn't have some electronic display like a petrol station does.

@@christophercharles3169 I would have thought there was some legislation that says Petrol and Diesel prices have to be prominently displayed, as they are constantly across the country;. If there is legislation, why doesn't this transfer to EV charge stations and why aren't weights and measures or some king of public body who protects the public getting involved.

​@JamesRattray Rubbish ! If you want to 'sell' something cheaper than your competitors up the road , you display your prices . If you're an EV driver with range anxiety because your aircon's on and the 50 miles you've got left to go will use 65 off your already low battery , you'll cough up out of desperation. They KNOW this ! 5 minutes to 'fill up' 30 to an hour to charge up (plus the calories) while you WAIT , 9 x 10 in the rain , without cover ! 😴😴😑🤔🤔

@@johnnydoe1984 When ever there is change, when ever there is something new, all be it when steam trains first arrived, the motor car, planes, the internet, social media or EVs there are always those who don't embrace it and tells everyone else why it wont work. I take it you don't have an EV. I do and I love it, it is so much easier to drive, no oily engine that needs looking after with annual services, no gear boxes and all those gear changes. So easy to refuel, as electricity is everywhere, I use a 3 pin plug when staying with friends and family and holiday cottage that don't have chargers. I have had my EV a Kia Nero EV2 for 18months, I would not go back to an internal combustion engine. Thanks for sharing your thoughts.

Thanks for the comments. When I started the HP project a EPC of C or above (+some other specifics) was required. Since then the rules have been changed/relaxed. You're of course right, weather comp doesn't use the internal T. The 10mm drops vary in length, but I'd say the longest is probably around 5m. None of the radiators are over 1000W. The biggest is 855W.

@@895522 thanks for replying 👍

Love you know your reasons why not? I have had my EV 18months, I drive up to Scotland two or three times a year with no issues. 10 days ago I drove 350 miles with one charge. A full charge when I started and a partial charge, just enought to get me home. Charging at my home is 9p per kWh as opposed to 80p per kWh at the Service Station.

Yes, I know. I got my EV because my brother has a Tesla, which broke down the barriers oif the unknown. They way Tesla has its charge pints built into its sat nav, is way ahead of my Kia EV. I am just jealous.

If you can afford a Tesla

@@stephenfell9817 I think the pric3es are falling. Give Tesla credit, they have forced the car manufacturers to go EV and Tesla has taken loads of market share, they have been a game changer for the auto industry. I have had a Kia EV2 for 18 months and love.

@@stephenfell9817 no different to saying’ if you can afford a BMW / Audi / Merc’ New cars are not cheap. Can’t hold that against EVs

I am not sure if EVs are any good for towing. I haven't noticed one towing anything. But you make a good point about how they are charged compared to a fossil fuel pump where you drive through. What I like about EV charging, is ther is no special trip to the pumps, as you just charge the EV while it is parked and you are getting your coffee. No canopy - well I just plug it in and walk away, I don't have to stand there holding the fuel pipe as with a fossil fuel pump. But, I fully accept EVs aren't for everyone.

@@JamesRattray But you'll still get wet plugging the car in, if it's raining. I would say the majority of times that people fuel their cars, they don't need a coffee because they're not stopping With EV's you don't have the option. EV owners do have to make special trips to charge their cars, especially if they don't have home chargers but also because EV's generally have half the range of ICE. When you're filling up your car with fuel you're holding the fuel nozzle for maybe 2 minutes, max. That's it. Probably less time than it takes to walk for your coffee. But I fully accept that ICE isn't for everyone.

@@alunjones2550 Speaking as a relatively new (18months) EV owner. I don't see the need for a canopy, it literally takes a few seconds, may be a minute to 1. Put charger in to the vehicle's charge port. 2. Swipe my credit card at the chargers credit card reader and walk away. Job done. Regarding your comment that most cars don't need coffee breaks. How long do you drive without a break? For me I like a break after 2 to 3 hours of driving, for a pee, a cup of coffee, may be a bite to eat and a stretch. Driving to and from Scotland from South Wales which I do two or three times a year, I leave the house with a full charge, giving me a range of just over 200miles, roughly 3 hours driving. I pull in to a motorway services and park the car as everyone else does, whether EV or not. The difference is I park it in front of a charger, plug it in and set off to use the facilities. The rapid chargers means the car is charged in about 40minutes or so. We often find ourselves scrambling as the car is charged, to get out of the charger bay to set off for the next leg. For instance, two weeks ago we drove 350 miles with one stop from Scotland. The ICE range versus EV is only critical if you drive longer than 3 hours or you drive where your stop over has no charging facilities. I would question the value of having an EV if I didn't have home charge facilities. With Intelligent Octopus it cost 7p per kWh of charge. Most domestic customers pay around 30p per kWh. EV's get this rate as they charge overnight when the National Grid has low demand. Most cars spend more time parked up than on the road. When staying with family and friend who don't have chargers, I use the 3 pin plug from their house. I put a meter on so they can see I am not draining the house of all its electricity. Electricity is everyhwere unlike fossil fuels. My brother, (which you can see in a separate video) said he anticipates the cost for running his EV (doing about 10,000 miles), his home lighting cooking and heating his house (just installed a heat pump) will cost him £300 a year. He has 18 solar panels and house battery. I believe this coming autumn, after he has run his heat pump for 12 months, he will do another video showing it has actually costs him nothing. There is a revolution going on that most people seem to be unaware of. I have driven ICE vehicles for over 50 years. I would not go back to one, driving an EV is just another level of ease, so simple. Thank you for this discussion and you raise some excellent points.

​@@JamesRattray For 95% of people, 95% of the time, they're not doing 2-3 hour journeys on a regular basis which is why you do not need a coffee break when charging or fuelling up your car. EV's are without doubt, the future but I am a chartered engineer and would not dream of buying one any time soon as the battery technology is woefully short of where it needs to be, the EV charging infrastructure is very poorly designed, unreliable, too expensive and too disparate in its charging structure. Finally. The "revolution" that most people seem to be unaware of is not a true revolution. It is an enforced revolution due to government mandated legislation change and nice cushy tax breaks for company car users. There is still grave reservations by many people "who by the way, are aware of the revolution", that EV's are not as good as they're alleged to be. This is why the demand for EV's has softened and the resale value of EV's has plummeted. It's the people buying 10, 15, 20 year-old EV's who will be the true arbiter of whether these cars are any good and I personally have very little faith in that being the case, but thanks for the discussion.

@@JamesRattray Very few people I know make special journeys to fuel their ICE. I do exactly the same as I would with an EV. On my journey if I need to fill up I just pull in to a petrol station fill up but unlike an EV I’m on my way in 5 minutes. I don’t ever feel the need to drink coffee on my journeys

It is an interesting point you make. There is such a difference in price 49p Tesla and 79p Grid Serve. If the prices were displayed prominently as they are with fossil fuel Petrol and diesel, I am sure more people would choose Tesla. Also does everyone know Tesla have some chargers open to all?
