No, it's a no brainer particularly if you get an FETF grant for it.

Primary coil will be a sealed system -no scale .
Water softenor for water supply to heater ? How do cope with scaled elements now?

Mines been in 4-5 years now and don't seem to have a problem. Our water is ridiculously hard and sludges up the main tank even with a softener. However I think because the heat recovery tank only gets to 50 the scale drop out is far less.

Only use electric heaters where coil doesnt touch water.No water softner see scale in kettle was wondering if coil in heat recovery scale over time

Water softener is not cost effective, look for Siliphos or Combiphos, keeps our heat exchangers clear, only needs a 6 monthly cheap top up.

We use a few Nordic Tec plate heat exchangers for hot water https://nordictec-store.com/gb/59-phe-plate-heat-exchangers and find that without Siliphos they are blocked in a few months, otherwise do an excellent job.

Don't know, bad lime here so fitted £500 water softener (works on salt tabs).

The heat recovery was at 60 yesterday.
