Resources
Famous Burkay reliability. Because of their lightweight and compact design, they may be easily transported on a two-wheel dolly replacing large boilers in a much smaller space. Burkay models are for indoor use in installations requiring higher inputs up to 670,000 BTU. They can be manifolded for unlimited fire power.
Energy Star Certified::
No
- 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.
- 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.
- Directly above the coil and the main burner is a compact, horizontial, 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 entertainmentof air.
- 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 the end of heating cycle to remove usable heat from the heat exchanger and reduce the scale forming tendencies of motionless hot water.
- Proven pilot ignition systems provides flame failure response in under one (1) second.
