Grant have released details of their r290 heatpumps

As before I think it's a rebranded unit from another manufacturer but I don't think itvs Chofu, who make the current r32 units. 

 

At first glance the performance seems to be about the same (unsurprisingly as r32 and r290 units have very similar performance characteristics)

 

The biggest difference apart from the units being black (yay!) seems to be the size. The r290 units are significantly wider. 

 

Still. Nice to see another entrant in to the fray.

They have taken their time! I saw the new R290 model on the Grant stand at the NEC in summer 2023, and was told like the R32 model it was made by Chofu and would be on the market winter 23/spring 24.

It might be a Chofu unit, but Chofu haven't got it on their website yet (which I would expect). 

 

It's interesting it seems to be bigger (power for power) than the chofu r32 units - which were nice and compact. 

 

They do seem significantly quieter though so maybe the extra size is sound insulation.

Notably both the Daikin R290 and the Samsung R290 units are larger and quieter than their predecessors.  I think its reasonable to conclude, as you suggest, that the extra volume is to accommodate sound insulation.

 

Unfortunately in the case of the Samsung unit for certain (not sure about the others) this pushes the volume over 0.6cu m which is the max allowed under permitted development.  Hopefully this figure may be raised soon, as suggested in the consultation carried out by DENZ earlier in the year (before the election).
