The Controlling interface console is a joke. Does anyone has successfully integrate this in to the home Assistant ?

Finally! It’s amazing to see such an experienced engineer with a wealth of experience providing content. Clear and informative and your free music doesn’t want me to gouge my ears out. Subscribed and engaged. Thank you sir

Nice video. Thanks!

Greetings from Buenos Aires, Argentina...great job you did with the Altherma...beautiful machine, that machine has not arrived here yet, from Daikin...greetings friend, good luck

When we buy the dam thing should have a course on how to service ourselves. Not worth the cost

why would you set a weather dependant curve for underfloor heating and another for radiators when you fit a low loss header?as your thermostats can be calling for both underfloor and radiators together and all water is mixed in the low loss header anyway, but in general a nice job,

Just wondering if the indoor units require an isolation switch also as well as the outdoor units? I'm hearing conflicting information

Hi , how has this held up? Have you returned for servicing? any issues from the last year?

Excellent video, good job

Hi! Just discovered your channel. Are you satisfied with the Arostor? I also want to purchase one. Thanks!

This is only for hot water, and not for heating yes ? Could such a system be used for home heating too ?

I would also use a rubber gasketed flare cap with a small hole drilled into the cap to test the Schraeder valve tightness after the system has refrigerant pressure. I would not introduce leak soap into the Schraeder valve cavity. Then I would replace with the factory caps.

I would also place the micron gauge as far away from the vacuum pump as possible. This means on the liquid line valve in this case. You may have 63 microns at the pump location but a higher reading on the liquid line valve. Granted, you have short lines and a deep vacuum here but as a rule of thumb I would want the micron gauge as far away from the vacuum pump as possible.

I would also exercise the valves on the core removal tool to allow any air to be released from the valve. I would do this before starting the vacuum pump each time.

great job and use of the latest tools Bravo!! I would add a nitrogen sweep initially however before the first vacuum. Why not take advantage of the dry nitrogen pressure to push the oxygen and any water vapor out before starting the vacuum.

nice video but I would never put a set of gauges on an Inverter Heat Pump. You loose refrigerant and because it is critically charged it affects the system greatly. Access sensors from Fieldpiece or Yellow Jacket are available that will hook up Bluetooth to your phone and if needed you can hook up a short 3-foot hose to them if you need to adjust charge. Also, the indoor units need to be properly power washed and then rinsed properly including the drain pan. The blower wheel needs to be removed and cleaned as well. There are kits to do this work to protect the walls and floors. I know these units are only 18 months old but when they get 2 or 3 years old, they will need a more in-depth cleaning as I have described.

isn’t the electric connections too close the r290 I thought it had to be at least 2 ft away in case of spark as part of U.K. code requirements

Really enjoying these videos!

Which no loss valves have you got?

Just wondering if there was any news on the Daikin. Multi-split hot water solution available in the uk yet? I’ve got a granny annexe that I’m putting air2air in but still need a small hot water solution for a bathroom and kitchenette

nice work :) how much high pressure should be in heating side bar? and how much low pressure should be in evaporator bar? thanks in advance

I think Ryan is your equivalent of Jeremy Clarksons Kaleb😁

i would have thought mixing with cold water just means less water needs to be heated so it's a zero-sum game. surely the inefficiency comes from losing heat while it sits in the tank but i think i heard him say that's minimal nowadays.

Our Gov wants everyone on HeatPumps, but flats are a difficult area to convert. A to A would be an ideal solution.

No update? I suspect if the claims made about heat pumps were true there would have been an update crowing about it.

What kind of wet vaccum cleaner do you use?

Give him a Daikin t-shirt.

Would good to see more content from your channel.

Fascinating stuff and further convinces me to go air to air. My mini split system has a SCOP of 4.1 and it produces a much more pleasant heat, albeit it was bought for its cooling capability. So in theory with my respective cost/kw for gas and electricity it should be approximately 20% cheaper to run than gas. Unfortunately I do not have a COP value so perhaps my figures are slewed but unlike gas heating the wait time is pretty much instant and I actually achieve setpoint which is something the gas system struggles to do.

Very tidy work, I liked the care and attention with the pipe flares and use of grips which don't mark the brass nuts.

Why do people who install heat pumps always seem to have a huge water cylinder? Unless someone has a bath every day no one needs much hot water - showers are about the only thing and a simple 10.5 kw electric shower does the job. Big waste of space and so much pipework for no reason.

Personally if I was keeping tools in the garage (as this client was) I would have had piped both the inlet and exhaust to outside. I think you overlooked the impact on the dew point in the garage.

Any updates on this system?

The dinosaur was funny!

Where id you get those red parallel jaw pliers from? Never seen them before! Great video guys.

That wall hung unit looks out of level

Would the Daikin split system with DHW option recover heat when the indoor units are in cooling mode? I've seen some desuperheater products in the US that use air cons to heat up their swimming pools. Probably won't be a VRV type heat recovery system as those are quite expensive.

What do you use to heat domestic hot water... And the towel rail in bathroom

The outdoor unit is wired in SY cable, bad practice as it is neither waterproof or UV resistant

Daiken now do an air to air heating + hot water

I'm looking to get air to air in my house. Who can I contact?

Great video... I'd love to see more videos from you as you're a great communicator. 👍

Interesting stuff, thanks! Didn’t seem like a stocking filler.

With a bit of a search, I have yet to find any cases of legionella in single family domestic houses in the UK. I have found some in multi occupancy buildings like flats but not houses. Can anybody demonstrate otherwise? I'd be interested to know.

I nearly fell of my chair when they said the cost per day. I want to know how much a heat pump radiator heating would cost per day?

Fair play brilliant set up. Looks like a great company you've set up there too

Have you made an update video?

4:00 …Yes you are right it is cringe.

I had no idea the installation was so ugly, I though all the big connections would be in the wall cavity.

Don’t follow this chap’s analogy, heating water to cool it down is energy wasted? No it’s not wasted because if one has lower temperature water then one needs to draw more of it from the tank, that means the same energy used. If one has a larger storage of hotter water it goes a lot further and the only difference is the energy losses through the wall of the tank.. in our case it’s not that much but more to the point it’s in a cupboard that is used to air our clothes, that small heat loss is also inside our house.
