Lol! It was so interesting it too 5 years for someone to reply "That’s very interesting."

 

Easily done though.  

 

On topic our quote from HSL was £6k for a 170m2 single storey, supply and commission (self-install).   I am sure we could have done it cheaper but I am very happy with their design, which I feel is high-spec, with a Zehnder Q350 at its heart.

I have the same, but we decided to retrofit electric heaters in our bathrooms a few years after we moved in. It wasn't like they were freezing, but stepping out of the shower onto unheated tiles wasn't very pleasant in the depths of winter. I also found that a bit more heat reduced the amount of condensation we were getting when it was cold.

 

If I were doing it again I'd absolutely have gone for some form of UFH in the bathrooms. Some have used electric mats under tiling to good effect.

 

The rest of the upstairs is fine unheated.

I was interested to understand how things turned out after 5 years.  You have answered my question and I will consider just installing UFH in the bathrooms upstairs.  I assume that without MVHR the temperature gradient between the lower and upper floors would probably be greater?

Never assume anything. MVHR is ventilation there is very little heat movement going on. The flow rates at about 0.5 air changes per hour so not a lot air movement going on either.

 

The ground floor heat is carried via convection current upstairs. It will occur with or without any ventilation present. Warm air is less dense than cool air, so goes upwards like it not.

 

I would have your UFH in the bathrooms AND an electric or dual fuel (water and electric) towel rad.
