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.
BRAZED PLATE HEAT EXCHANGERS
When it comes to co-generation and tri-generation
plants, Rheem’s new Brazed Plate Heat Exchangers
(BPHX) have been designed to be used wherever waste
heat from water sourced processes can be recovered
and used to heat potable hot water.
Rheem’s BPHXs have already been used in a range of
projects including:
∫ East Village, Victoria Park NSW: a mixed use
residential and retail precinct, where four plant
rooms serve a total of 223 apartments using the
heat exchangers in conjunction with a tri-generation
plant.
∫ Audi Centre Sydney, East Village: One of the largest
Audi service and parts facilities in the world, with
10,000 square metres of floor space and 48 service
bays. Heat exchangers have been used in the plant
room of this facility.
∫ Central Park, Abercrombie Street Chippendale,
NSW: Two plant rooms serve the 275-bed student
accommodation facility.
The WaterMark certified Rheem BPHXs have been
designed to offer a high level of thermal efficiency
and durability in a compact unit. They’re suitable for
water to water only applications, and are well suited for
installations such as co-generation and tri-generation
plants, process heating or as a separator in circuits
using PP-R piping.
The heat exchangers offer a high level of leak
protection, safety, thermal efficiency and durability in a
compact unit. Key features include:
∫ 316L stainless steel
construction
∫ Single wall brazed plate heat
exchanger
∫ Low pressure loss
Accessories:
Pump C Controller P/No
6060262-4 Rheem 610340
and 610430 vitreous enamel
storage tanks or a range of large
capacity stainless steel tanks
available from Rheem.
THE PERFECT TEAM
The e.Control from Bosch allows solar power to be used
to its optimum potential for own consumption. This
creates independence from electricity purchased from
the public power grid, thereby reducing electricity bills.
The combination of inverter and heat pump maximises
own consumption, as PV power supports the heating of
hot water.
The e.Control control unit stands at the centre of
the networked system. It identifies the energy flows in
the house and ensures that all running consumers are
supplied with solar power first. This means that even
the heat-pump is driven using PV power, before any
surplus power is fed into the public grid, for a small fee.
The perfect team – the Bosch BPT-S string inverter
and the Bosch Compress 3000 air to water heat
pump are fully attuned to work with one another
and e.Control; therefore provides best use of your
customers’ PV generated energy and storing it in form
of thermal energy (i.e. hot water) in the Bosch heat
pump.
The conversion of electrical energy into thermal
energy causes the capacity of the stored energy to
increase. Users of a networked system like this, with
components made by Bosch, make themselves largely
independent of power from the public grid and from
fossil fuels.
