Repeatedly topping up a heating system
causes damage and the need to do so
may indicate the presence of a leak.
The accessories and materials supplied
together with the accumulator must be
installed and operated according to the
manufacturer’s instructions by a suitably
qualified professional fitter, allowing for
statutory regulations and precautions.
The supplier must be notified
immediately of any problems arising from
these accessories.
