Thanks for the reply,

I did think about the gas pressure it's LPG and the tank is only 25%
full, I've been waiting 2 weeks for calor to fill it up. I'll wait to
see if filling the tanks helps before trying anything else.

This seems pretty unlikely, because there is a regulator between the
tank and boiler to set the gas pressure to the required level.


We are in a very hard water area, we were thinking of getting a water
softener, would this be OK with a combi boiler or would it reduce the
pressure to much?

It won't reduce the static pressure at all.

It may have an impact on the flow, which may make the working pressure
that you feel a bit less. However you can get water softeners that
have high flow rates.

If your heat exchanger is scaled up as has been suggested, then it
would be prudent to get that resolved first.

A water softener will certainly prevent scaling and will save you
money on detergents and shampoos - will cover the cost of salt.

A less expensive alternative is to use a phosphate dosing unit like a
Combimate. This will prevent the scaling but not help with
detergent use.
