Finding ASHP installer who understands fan coils

[flanagaj]

I have spoken to a few local ASHP installers in Hampshire and the moment I mention to them about using the ASHP in cooling mode and having a split system which enables the UFH to be run above dew point in the summer, but have the upstairs fan coils with condensate drains to run at a colder temperature, they just tell me "No, you cannot do that".  Now, I am sure I have read on here, that people are doing just that.

If anyone is doing that, do you have a diagram or even a contact in the Wiltshire/Hampshire/Berkshire/Surrey area of a heating engineer who know and can do what I am trying to do.

Here is a Haier scheme, you just setup as a 2 zone system. Each zone with a different flow temp fixed or WC. The image shows a buffer which is unlikely to be needed

@SBMS Is in the process of doing something similar so might have a suggestion.

 

Only some heatpump makers (like Panasonic) actively market this as an option so if your installer usually works with a brand that doesn't talk about cooling then it's not a shocker that they are uninformed. Though I tend to think if your business is selling/installing heatpumps then you are doing a bad job if you aren't on top of all the options in the space but this seems par for the course for much of UK installers.

Pump 1 to the fan coils and pump 2 to the UFH? Is it a given that you need pumps?
