Sample specification
Gas-fired water heater will be an A. O. Smith BFC series or equivalent. Condensing direct gas-fired water heater with 8 bar rated and 12 bar tested glass lined tank, foam insulated and meeting energy class A per European regulations. Glass lining to be made by the water heater manufacturer to ensure glass matches the thermal and physic expansion properties of the steel. Heater will have a modulating pre-mix gas burner with automatic gas/air mixture regulation, easily converted from LP to Natural gas. Internal double loop spiral burner chamber and heat exchanger will ensure a 97% heat transfer efficiency and prevent calcium build up on heat exchanger. Burner will be low NOx (≤ 30PPM) and low noise. Low maintenance inert electric anodes to ensure additional corrosion protection. Heater will have electronic programmable controls with week programs, status and fault indication on display, anti-legionella cycle, programmable circulation pump relay and BMS connection for fault report. Heater will be factory supplied with brass hot and cold water connection and drain valve. Venting material to be supplied by water heater manufacturer to ensure easy long distance safe flue gas discarding up to 100 meter.
