- Conservationist® Burkay® high efficiency gas boilers are designed for indoor use in installations requiring higher inputs
- They're rust-proof because water comes in contact with nothing but copper, brass or bronze
- The Burkay® burner features a patented design that maximizes combustion efficiency
- All non-ferrous waterways
- All castings are made of bronze or brass
- All water tubes are made from copper
- Brazed joints or flare union construction make the boiler immune to the effects of thermal shock and thermal cycling
- A great boiler for domestic hot water supply
- Efficient copper coil combustion chamber
- The combustion chamber is a heat exchanger formed from a two passage coil of tightly wound continuous copper tube
- Water circulating through this coil surrounds the main burner and captures the radiant heat
- A wrap of insulation on the outside of the coil retains the heat captured by the circulating water
- Copper heat exchanger
- Directly above the coil and the main burner is a compact, horizontal, copper fin tube heat exchanger
- The flue gases must pass through this efficient heat exchanger before leaving the boiler
- This unique Burkay® coil and heat exchanger design provide maximum heat transfer and proven field durability
- The patented Burkay® burner uses primary air injection at up to 72 individual orifices plus secondary entrainment of air
- Burkay® burner approved for installation on combustible floors as shipped from factory
- Slow opening redundant gas valves ensure smooth light-off without flame roll-out or pilot outage
- Patented pump delay system that allows boiler and pump to run simultaneously but delays pump shut off at end of heating cycle to remove usable heat from the heat exchanger and reduce the scale forming tendencies of motionless hot water
