DESCRIPTION OPERATING PRINCIPLE CONSTRUCTION FEATURES The HeatMaster is a high performance, direct fired hot water storage heater, which has indirect heat transfer due to its Tank-in-Tank construction. Outer body 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 (neutral fluid). The outer shell extends down to the combustion chamber and even around the flue tubes.
