HeatMaster® 60
Simple, Well Proven Performance
At the heart of the HeatMaster is a stainless steel
cylinder through which the flue tubes pass. This is
surrounded by a mild steel shell containing the
primary water.
The outer shell extends down to the combustion
chamber and around the flue tubes. The heat transfer
surface is therefore much greater than that of standard
direct fired water heater. A circulating pump fitted to
the primary circuit moves the water around the tank,
heating it faster and maintaining an even temperature
across the primary jacket.
The burner fires into the combustion chamber which
indirectly heats the stainless steel cylinder containing
the DHW. As with all Tank-in-Tanks, this is corrugated
over its full height and suspended in the HeatMaster
by its hot and cold water connections.
It is capable of operating at very high temperatures.
Key Benefits
• Limescale build up is prevented because the:
- cylinder expands and contracts during use
- cold water does not come into contact with
the intense heat of the burner flame
• No need for sacrificial anodes due to:
- scale resistant features
- corrosion resistance of stainless steel
• The HeatMaster has one very major advantage over
other direct fired water heaters
- because it heats the DHW with a primary
circuit, this primary water can be used to
provide central heating as well
• Most hot water and heating demands can be met -
simply by connecting two, three, four or more
HeatMasters together in a module.
• The HeatMaster range can be used in conjunction
with SL and Jumbo hot water storage tanks –
supplying even the largest hot water requirement.
High performance, combined
direct fired boiler and water heater.
Can also be used as a stand alone
water heater.
