List of ASHPs with cooling capability

[Stu789]

Are there any other reversible monobloc ASHPs in the 4-5kW max output range...

Daikin EBLA04 (R32 based)

Vaillant aroTHERM Plus v2 3.5kW

Samsung 5kW Gen 7 R290 

Grant Aerona 290 4kW HPR2904

 

TIA

Haier R290 4kW, comes out the box setup for heating and cooling, wouldn't bother with R32 as R290 in the real world performs better as they are generally the next generation design.

Midea M Thermal. Pretty trivial to switch between heat/cool/both using the built in controller

Of the modern r290 ones are there any that don't support cooling?

Octopus, Ebac, a lot of Mitsubishi and Daikin ones, don't support cooling at all and others. Valiant needs a widget to make it work, Grant only enables cooling if you do not select radiators within your heating system.

 

Not sure about Viessmann.

 

Panasonic does support cooling also out the box.

Wow, ok. That's a lot more than I thought.

FWIW one of Valliant guys on their stand at the NEC a couple of weeks told me they included the resistor for cooling with the plus model.

Well I raised potential cooling with the service engineer who came today. Mines a Vaillant and whilst it apparently can do it he didn't recommend it as the "underfloor pipes can contract and crack the concrete". I wasn't going for the sub-zero approach, merely say 16 degrees.......

That will be right - not 

[kandgmitchell]

Quite!

We have a 6kW R290 Maxa.  Slightly higher power than you ask for but seems to be ok.  Comes in a pleasant colour too (for it’s position in our garden).

 

Is there any difference in sound level in general between R32 and R290?

Comparing our Maxa R32 (now heating our hot tub) and Haier R290, the R290 makes slightly less noise, but both are not noisy. The R290 has a bigger fan that runs slower and a bigger evaporator, so air flow rate is lower circa given load.
