HeatMaster® 60
High performance, combined
direct fired boiler and water heater.
Can also be used as a stand alone
water heater.
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.
