Water softener whole house system and reverse osmosis droning water filters advise please.

Mr.Plinky

Hi really need some help and advice please. 
House is being fully refurbed. 
Plumber has set up 3 inlet pipes on our main water supplies as hard water area Poole, Dorset area with the following intended setups:
Pipe 1 straight feed to garden tap
Pipe 2 whole house kitchen, bathrooms x2 heating system want to put on water softener for Limescal reduction/removal
Pipe 3 drinking water to kitchen using a reverse osmosis system

The kitchen will have a 3 way yep 1 for drinking from the reverse. Osmosis filter and 2 for hot cold system feed from the softener. 

Both filter units will be housed under the stairs.

So in researching the two we originally considering were salt based however as we have a mix of the original copper pipes the salt system concerns us.

So what are the best alternatives without salt to consider. I have seen the following but not sure if those is suitable for whole house or how it works.

 I did find a little reference regarding it below which made me wonder if this could be an alternative.

We are really seeking any advise and help.

What is your perceived issue with old copper pipework and ion-exchange water softeners that use salt?

I'd avoid the 'snake oil' water conditioner devices, myself.  I'd also avoid any electronic control softener.  Ones that use a mechanical meter to regenerate would be my choice.

AIUI though some central heating systems installation manuals may deprecate the use of softened water in the sealed circulating water system. So that may be a slight issue?  (Although any decent softener install will have a bypass tap to supply mains water so could be used to fill the CH system.  A little soft to rarely top up will likely be harmless.)  e.g. https://www.worcester-bosch.co.uk/professional/support/troubleshooting/faqs/all-faqs/can-i-use-artificially-softened-water-in-the-heating-circuit-with-my-boiler
My Grant Kereone boiler has no such warnings in the manual.

We had your system, water softener + RO filter for years. We’ve now moved to just having a water softener and we drink softened water. This has now been deemed safe. Saves the hassle of getting the RO filters changed every 6 months and less things to go wrong.

I am about to renovate my flat and would like to install the same, could you share some recommendations for the softener and the RO system?
Thank you.

I went to the ideal home exhibition one year and talked to a company that had a stall there. They assessed what we needed and arranged it all for me. I’ve had good service from them ever since, so happy to recommend. I’ve no other connection with them. friendlywater.co.uk (I live nowhere near them, they seem to cover a wide area).
