HOT WATER NEWS
WHAT’S HOT IN HOT WATER
PLUMBING CONNECTION TAKES A LOOK AT WHAT IS CURRENTLY MAKING NEWS IN THE EVER CHANGING HOT
WATER SECTOR.
SAVE ENERGY, WATER AND
MONEY
With the continuing emphasis
on environmental performance,
the search for more efficient
and effective water heating
is becoming increasingly
important to commercial and
domestic consumers.
Stiebel Eltron has been at the
forefront in the development
of renewable energy products
− such as heat pumps − for
more than 40 years, and in July
2016, the company released an
all-new range of models to the
Australian market: the WWK 222
(H) and WWK 302 (H).
“It is an exciting time at Stiebel Eltron Australia as
we celebrate the company’s 40th year of developing
renewable energy products in Europe,” Glenn Day, Sales
Director Stiebel Eltron Australia said.
“We have been selling the heat pumps developed
from this research for nearly 10 years in Australia.”
The latest range of innovative units from Stiebel
Eltron will set a new benchmark for domestic hot water
heat pumps in Australia. These air source hot water
heat pump systems harvest natural energy to reduce
electricity consumption, lower hot water energy bills
and reduce environmental impact.
“All aspects of the design have been carefully
considered from the perspective of the homeowner
through to the installer,” Day said.
“Like all excellent things in life, it has taken time to
develop, but the wait has been worth it!”
Compared to conventional electric hot water
systems, energy consumption for heating water can
be reduced by more than 70 per cent by using a WWK
222 (H) or WWK 302 (H). The units are therefore eligible
for government rebates and help to achieve Australia’s
Renewable Energy Target by 2020. The sophisticated
design of the Stiebel heat pumps has been engineered
to work efficiently even at minus temperatures, and
a current impressed anode ensures a long life cycle
regardless the water quality.
REAL TIME WATER HEATER STATUS
Rheem Australia’s Heavy Duty Gas BMS (Building
Management System) interface module is designed to
facilitate the interface between individual gas water
heaters and building management systems, which
remotely provides facility managers with real time
water heater status.
The module uses the water heater’s own power
supply and is suitable for indoor or outdoor installation.
It mounts to the outside of the Rheem gas water
heater and can be used for both new installations and
for retrofitting to existing water heaters. It is also
provided with common, N/O and N/C contacts for field
connection by on-site trades.
Identifying any issues is also simple, with the module
providing a run/fail signal via voltage-free contacts
(common, N/O, N/C). It also features an on board LED
status.
Operation modes include:
∫ RUN (N/O): Water heater is heating water or is at
temperature (green LED)
∫ FAIL (N/C): Gas valve lockout or over-temperature
cut-out trip, or loss of power supply (red LED or no
indication)
The Rheem Heavy
Duty Gas BMS interface
module suits Rheem
models 621265, 621275,
631265 and 631275. Its
dimensions are 231mm (h)
x 112mm (w) x 78mm (d).
