Daikin Altherma 3 RF Heat Pump - we fit one for the first time 

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

This has to be the finest Heat Pump installation yet i have watched on youtube and as a prospective customer in Ireland this has demystified the installation set-up for my partner and also my colleagues & neighbours who are also considering a heat pump purchase

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.

Really enjoying these videos!

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

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.

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 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 think Ryan is your equivalent of Jeremy Clarksons Kaleb😁

Nice work👍Very professional. Are these more effecient than having a heated water unit and pressurised cylinder, rather than having a gas refrigerant to the unit?

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

My gas boiler needs replacing so I thought why not have a heatpump for the hot water and underfloor heating. Goodness me it looks so complicated especially with all the detailed servicing in another of the videos. I think I'll stick to the gas boiler.

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,

Nice first video 👍

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

In my country Daikin instillers telling me that they don’t put buffers any where that they instal pump? How is in Poland and your experience? Isn’t that bad for short cycle for compressor? Thx

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

Give him a Daikin t-shirt.

Nice video 👍 do you need any inserts when pressing onto the soft copper? And where did you get the internal former for hand bending the pipework from? Cheers

I though you couldn’t install these under a window, it has to have 4 ft clearance because of ozone from the gas

why not soldering ?? why making flares and press fittings? the best way is soldering

Will it not void warranty using nylock instead of fridge oil on the flares?
