Renovating a Kitchen and considering Single Room Heat Recovery

[Jeremy]

Hi all, as per a previous post, I'm renovating a drafty old house (yes, draughtproofing, interior wall insulation, new windows, etc.) and installing an ASHP to run radiators. I'm now looking towards the kitchen more specifically. I'm aware of the need to have good ventilation and air exchange in the kitchen, but am reluctant to lose all that heat out an air vent. Wondering what experiences folks have had with single room heat recovery devices (like here: https://www.kair.co.uk/product/kair-heat-recovery-room-ventilator/).

Has anyone installed one of these? Found them to make a reasonable difference?

Three years ago, I put one of these in to cover a large open-plan conversion: https://www.vent-axia.com/range/hr200wk

Works well, and reasonably quiet on low speed. Wire in a boost switch to make it spin up to max.

We have a couple of single-room MHRVs, which are probably going to enable us to keep the heating off over the next few cold days!

 

In the kitchen we have a (pull-to-boost) Tempra and are happy with it:

Thanks @DamonHDand @richi - glad to know the stuff works! Now I guess I just need to sort out whether to have timer, cord, humidistat, etc controlling it. I have a bunch of zigbee smart home gear to be installed so might see if I can run a DIY humidistat...
