Any reasons not to go with a Nibe ASHP?

[Great_scot_selfbuild]

The ASHP market is a bit of a minefield, and I recognise that many will have their own preferences. I’ve done a lot of searching/research and have a quote that I have all-but committed to. The company does also supply and install other makes (Vaillant, Daikin to name just a couple), but they have started to install more and more Nibe.

 

I’ve had Nibe recommended to me personally, and have heard positive reports about their user interface in particular. 
 

So, whilst I am still keeping an open mind and will take on board recommendations about other brands, the main reason for this post was as a final check for any reasons why I shouldn’t get a Nibe (installed by an approved installer with a 7year warranty).

Nibe are excellent, but expensive and they control their installers very well. 

 

I have an F2040 and it's never missed a beat in 9 years.

No reason as far as I'm aware. I'm fully Nibe trained for both ASHP and GSHP and will soon have completed the NIBE Pro accreditation, so I could be considered slightly biased.

I say look at modulation - can it run all day long at most weathers?

 

As in not cycle?

Yes, thanks to this group, this is almost my first question to the supplier. If I’d became clear they didn’t understand modulation (some didn’t), then they ruled themselves out. 
 

The Nibe I’m considering does have good low level modulation.

Nibe (and others) use an energy integral, so if they are cycling they use a fancy time, to degrees of heat delivered calculation, so they can provide a higher than target temperature, to get a decent run cycle and time off, while still managing the energy delivery to house. Basically ensure short cycling is never an issue and energy delivery is on target.

My two cents worth:

I've been comparing ASHP specifications for far too long in the process of making a choice for my build. One of my criteria is the quality of the manuals and NIBE are good in this area. 

As mentioned, a lot of manufacturers don't give much info about the minimum outputs, but this data is in the NIBE installation manual (at least for the F2050 that I was looking at).

My concern about the NIBE was that it doesn't seem very DIY-friendly. It can obviously do everything (smart grid, inverter integration, machine learning, integration with MVHR) but only if you have a compatible inverter, MVHR and a bunch of NIBE smart controls. I prefer systems that support a more open approach e.g. modbus or volt-free contacts to control these functions, but that may not be relevant for everyone.

You only get the 7 year warranty with an approved install via an Approved Installer. Nibe are not catering for the DIY market

Nibe has a modbus module that you can add-on. My Loxone communicates with SMO40 controlled via it.
