Don't you think that with all the innovations in boilers and the
considerable logic now possible at a relatively low cost, that they
do not build in sensors that do the topping up automatically. This
would also serve as a leak detector as if it needed topping up a lot
there has to be a problem.

If th epressure gets low then the boiler shuts down and shows a fault.
Surely better than it automatically topping up just under the treshold for
a warning..
