I saw this article that mentions that Daikin recommend delta T =10 for radiator circuits. Does anyone know which of Daikin's ASHPs this applies to? (I asked Daikin, but they said to ask an installer, which didn't help much...)

That's hysterical that a manufacturer would defer a question like to this to an installer.

@grahamh do you have any words of knowledge here?

@editor Well, it is not the Altherma range, they are definitely Delta T = 5. Toodles.

That was Daikins answer to every single question I asked them during my discovery phase.  

...Which is one of the reasons I discarded them from consideration.


4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.
