Should I install a softener?


Your choice is:

1. Ion-exchange softener, which will have additional benefits, such as
preventing horrible stains on the sink/bath/toilet, feeling nicer on the
skin and using much less detergent. They cost a lot.

2. Phosphate dosing capsule, which will reduce scaling on heating
appliances, but have few additional benefits. They have moderate cost.

3. Electronic/magnetic conditioner, which help boost the bank accounts of
the charlatans that sell them.


Strange that the many major cylinder and boiler manufacturers recommend
them. I think W-B recommend them too. Gledhill, a quality company, do.

Is it a good idea to set the maximum temperature to 45C? (Presumably
this is the DHW temperature?) Would this result in any loss of
efficiency?


It would increase both safety and efficiency, as it help reduce the boiler
return water temperature. It would help a shower mixer remain at a stable
temperature and flow. The main disadvantage is that it isn't so good for
washing dishes.


If you have a dish washer that is really not an issue.
