a 50°C rise. The HD50i has a 125mm concentric flue which can be
extended up to 15m, less 1m per 45° bend.
Compact and reliable, the HD50i operates between 1-10 bar
pressure, which is suitable for mains and systems with boost pumps.
Incoming water temperatures in excess of 60°C are accepted,
making the HD50i suitable for secondary return systems. Water can
be delivered at high volume with minimum gas consumption. All
models have full electronic ignition with no pilot light and operate
on demand only, consuming no gas when not in use.
All Rinnai internal HDC condensing continuous flow water heaters,
are room-sealed, power flue appliances while the external
weatherproof models have forced exhaust which enables them to
be compact, saving both floor and wall space.

Rinnai’s unique condensing technology incorporates two heat
exchangers to achieve optimum water heating generated from every
cubic metre of Natural Gas or LPG. The condensing process delivers
up to 95% thermal efficiency, which translates to significant energy
savings when compared to standard on-demand water heaters or
conventional stored systems.
For applications where the use of stored hot water cannot be
avoided, i.e. in refurbishments where there may be a constraint
on the amount of gas available, usually through the gas main size,
Rinnai’s ‘pack’ system covers this shortfall by fitting a small amount
of storage capacity.
Rinnai Gas Hot Water Storage Pack represents the best value-for-
money solution on the market today with everything delivered
direct to site in one complete package
The pack consists of up to five heavy duty water heaters with an
equal number of flue kits (for internal heaters) or an equal number
of pipe cover boxes (for external models) and sufficient valve packs.
Also included is one hot water storage vessel (stainless steel 300L,
500L or 800L glass lined steel) along with necessary valves and
one primary pump with valves and one unvented kit. Add to this
an expansion vessel of either 50L or 80L capacity, and all relevant
valves. Common header flue systems are also available to further
stream line the installation.
Typical applications for the commercial ranges include cafés,
nurseries, factories and offices, laundries, hotels and restaurants,
sports clubs, shower blocks in caravan parks – and many more.
Rinnai has also embraced renewables in the form of the Rinnai
Booster, which, it claims, is the most energy efficient boosting
solution on the market today. The water heater maximises solar
gain, as it only functions and consumes energy when more hot
water is needed to boost the solar gain, meaning that the true
impact of solar is being achieved. The rest of the time the unit is
inactive.
