I visited Installer '22 at the NEC on Wednesday (told everyone who asked that I was a renewables retrofit specifier in the domestic sector, I'm not...)... My take-aways from the day:

1. Cool Energy had a demonstration trailer setup with their newer R32 based unit driving a very nicely made, Italian sourced, fan coil unit in cooling mode. They have a nice product and they're very technical and open. Units will ship with the newer Carel pGDX display in the future ( https://www.carel.com/pgdx ) and this is a nice display/interface. My visit and chat has cemented them as my chosen supplier for my domestic renovation project.

2. Unitherm heating (Exeter) had a good display of heat pumps from various suppliers on their booth, but nothing plugged in and working. They were one of the few companies there with LG units to see.

3. Grant, who supply Chofu units (Japanese origin) had a nice booth, but the real take-away from them was their nicely produced brochures and handover guide which do a good job of explaining to the homeowner how setback and weather compensation work. Nice to see them trying to educate the user in how to get the best from their system.

4. Midsummer wholesale have launched heatpunk (heatpunk.co.uk) a web based tool for graphical heat loss calcs. It's similar to the freedom toolkit except it is web based and runs in the browser. You draw your house, specify the building contruction and it does heat loss and rad sizing in a graphical manner. Free to use (for now). I asked about importing DXF plans and that's something they are considering.

5. Sunamp are listening and are working on a making their PCM43 more reliable in long cycles (that's why it isn't available yet), and are also thinking that PCM50 would be a good fit for heat pump applications.

6 (Leaving the best till last). Homely, by Evergreen energy - wow, this is a game changer. A modbus enabled, IoT based, smart thermostat and heat pump controller that takes control of a wide range of modbus controllable heat pumps and will optimise the flow temp and operating times depending on occupancy, weather, solar gain, predicted weather for the coming 24hrs, TOU tarrif data from the tarriff provider, storage battery %SOC, etc etc. It can automatically commision Midea and Samsung units over modbus and provides a full app for the end user to setup their schedules and temperatures. It has an indoor light/temp/humidity sensor that allows the unit to automatically setup the weather comp curves for a property, no installer callbacks, no fiddling by the user. I was very impressed with this and can see it being of real benefit to end users. They are going to enter a line of communication with Cool Energy to add support for their units.

All in all, very glad I visited. I'll go again next year for sure.

What about the other heat pump manufacturers that were there?

Everyone was there (except Freedom/Midea). Mitsubishi had their own booth, Unitherm had a multi-brand booth showing Samsung and LG units. Grant were there with a few units.

Stiebel Eltron had a booth, Bosch had a booth, Ariston were there with some weird looking monoblocs. Hitachi splits were on a few booths (I'm not interested in splits so glossed over those). Viessman had some monoblocs on their booth.

I could go on... You get the idea. It was heat pump city.

You didn't mention the two biggest stands with heat pumps - Vaillant and NIBE....

I went to talk installation specifics with Cool Energy (a brand I can afford), and to look at/prod as many controllers as possible to assess the HMI factor. I did have a look around the Vaillant booth now you mention it, they had an aerotherm plus with a perspex cover and all the copper work polished up. A nice touch and a good talking point for people who see these things as voodoo... I didn't stop by the Nibe booth.
