My Daikin Altherma 3 system, installed in July this year by Octopus, isn't anywhere near as efficient as he says it should be (ie, COP of 5 at 35C flow temp). Mine was achieving a COP of around 3.8 at outside temps of around 14C - with water flow temp of around 25C and a COP of about 3.2 for flow temps of 28C at 8C outside. I feel this is quite poor!
Morning guys I wondered if anyone can help our heat pump is oversized, what can we do to improve its efficiency?Its my fault really as at the time Daikin only offered a minimum of 9kw with the black grill which we liked the look of compared to Daikin other units. Our heat load is about 5kw at -2, i was thinking maybe a buffer could help but after reading these posts I'm totally confused. We have a 25litre buffer which I believe was installed for hydraulic separation and nothing else 25litre volume. The heat pump will modulate down to 30% according to the manufacturer but won't be enough on the milder days of spring/Auturm when we should be saving. Any help be much appreciated as electric has just doubled for us.
@@rosiertje We don’t have underfloor heating currently but will be looking to retrofit to the kitchen dinner in the future. We have a 200L hot water tank
Did you need to mention that Mateo works for Octopus energy selling Daikin heat systems .
What is the max distance from the heat pump to inside of the house. To connect with the boiler?
What is the minimum modulation of these series ?
When is this going to be available in the U.K. in any significant numbers? Not seeing this in stock anywhere…
Is there a link to a commissioning procedures video by any chance?

Do you have underfloor heating? Otherwise get that. And get langer buffer. And / or get a domestic water tank

Are people missing the obvious. Who wants a giant ugly box bolted to the side of there house ?
yeah, let's all just FCUK up the planet, instead.
People that want nice warm house and a pretty power bill rather than an ugly one
