• Main has an unrivalled reputation for
offering reliable, safe, efficient and
easy-to-use water heaters.
Quality you
can trust
• Installation is straightforward, thanks to the
simple 3-pipe connections with isolation
valves, pre-wired standard plug (FF) and
flexible flueing options.
• Ideal in homes with high hot water demand,
the Main FF (Fan Flue) and Main BF
(Balanced Flue) Water Heaters provide
instantaneous hot water without the need for
a storage cylinder.
• If you need to locate the heater away from an
external wall, the FF model is perfect. It has a
4-metre horizontal and vertical flue option
making siting easy.
• The BF option comes with a Piezo Spark
Igniter, meaning no batteries or wiring are
needed – and both models have clear
temperature controls.
• The key to our success is the simplicity of our
products. They do exactly what you need them
to do and they do it reliably. That means you
waste less time and money dealing with call
backs and maintenance issues.
