PIV or Ebac DHR

[B-Portwood]

Hi everyone!
We get a lot of condensation so had a PIV fitted in the loft a couple of years back. It has improved condensation on the windows a bit but does make the upstairs absolutely freezing (particularly over the past week). Thus, I'm no longer convinced that flooding the house with freezing air is the way forward. Retrofitting in an MVHR system would be far too costly in a 1970s house. Thus, I'm now looking at a compromise solution and stumbled across the EBAC DHR with heat recovery: https://ebac.com/dhr
Before I make another costly mistake and install something that doesn't help, I wondered if anyone had installed one of these and how they'd got on. It looks fairly straightforward on paper and promises much better results than a PIV. But does it work!?
Thanks in advance!

Do you have mechanical ventilation in both kitchen and bathroom and use them?. Do you dry washing in the home.

How isn't this unit just "MVHR but stick it all in the loft"?

Part of MVHR's advantage is they do extract/supply from separate locations, if you bin that a load of efficiency and advantages just go away?

Thanks for getting back on this. Yeah, we do have high speed kitchen and bathroom extractor fans that we use whenever kitchen/bathroom are used. Washing is done mainly outside unless it's freezing when we dry either tumble dryer or rack with dehumidifer downstairs

You might be right on this, hence why I was wondering how anyone had got on with one of these. It looks like an MVHR but only serving upstairs rooms, which makes it easier to fit with the ducting etc, but of course does it lose all the benefits? I'm not sure on this. Would be interested to know how others have got on with one.
