I have a 1.5 yr old Ariston combination boiler, for about a month now
I have had to keep filling the system from the filling loop every day
or two before the bolier will dispense hot water. This is annoying
when you set it to come on in the morning and it doesn't because the
pressure is too low.

Why am I getting this frequent pressure loss? what can I do to stop
it?

any tips on this greatly appriciated

Check for:

1. Leaks around the system.
2. The blow off valve is not passing. Drips will come the blow off pipe
that runs to outside.
3. The pressure vessel may be the cause of this and is blown.

Ariston combi's, well the Microgenus, have a two year guarantee. Check for
Nos. 1 & 2 above. If all fine then call them in under the guarantee.
