Closed-outlet installation (MDH and MDX)
The mini instantaneous
water heaters MDH and
MDX are approved for
unvented (closed outlet)
installation.
The connection set supplied
with the unit (T-piece and
flexible hose) simplifies
retrofitting to existing
closed-outlet taps.
Open-outlet installation (MH)
Mini instant water heaters with open
outlet design can be mounted very
quickly and easily in an open outlet
installation.
They are designed to supply a single
tap outlet. To prevent pressurisation
of the unit, a special open-outlet tap
must be used.
