Range Overview Hot Water
Mains Pressure Electric Storage
• Full range of capacities to suit all requirements
• Flexibility of various element sizes with dual handed connections
making them ideal for replacing older systems
• Choice of high quality long-life Stainless Steel or durable Vitreous
Enamel steel construction
• Stainless Steel cylinders are Solar compatible - added exibility to
upgrade at a later stage
• Flexibility - suitable for internal and external use
• Thermostatically controlled with safety temperature shut o for added
safety and peace of mind
Gravity Feed Electric Storage
• Low pressure gravity feed electric boosted systems
• Designed to be concealed in roof spaces
• Full copper cylinder with long life expectancy as unit not under
mains pressure
• Suitable to be installed in conjunction with Solar Collectors to
economically pre-heat the water
• Suitable for connection to a combustion stove pre-heat circulation
system in addition to solar – best of both!
• Available in a model with a built-in heat exchanger coil for mains
pressure capability.
Commercial Hot Water Systems
• Heavy Duty Continuous Flow units
– smaller Commercial applications
• Manifold Packs – multiple units plumbed
together with a maximum ow rate sized
to suit a set number of outlets (ie shower
block with pre-set outlet temperature)
• Demand Duo – single or multiple units
manifolded together in conjunction with
storage cylinders. Stored hot water assists
with ‘peak demand’ periods like mornings
in a hotel.
• Warm Water Systems designed for ow
& return installations
• Commercial Solar pre-heat systems
HANDY
HINT
Always err on the high side when sizing electric
systems. Under sizing can result in a lack of hot
water and very unhappy customers!
HANDY
HINT
Because the hot water is gravity fed, the piping
to the outlets & showers is usually run in ¾”
(20mm) to ensure adequate water ow!
