So I guess I am left with Vaillant unless 21degrees will come back with their updated quote.

Is that because the only people who will quote for 45C also quoted for Vaillant?  

Might be worth doing a stare and compare (between the quotes) on the rads and house loss estimates.  In the end the operating FT will depend on the rads fitted, not on the heat pump.  So if, for example, the guys offering Samsung are actually fitting the same or bigger rads as the guys offering Vaillant, the FT will end up the same (and almost certainly different to either 'design' temperature!)

Unless of course you have already decided to go for one or the other anyway.

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.

@jamespa I will wait for smart heating to come back with a newer quote (45C) and ask Sustain to provide their 45C quote based on a Vaillant pump.

Very sensible.  Get the 'second round' quotes in, hopefully puts you in a position to make a decision.
