Suburban SW6DERA Boiler

Faster Recovery - Fast recovery means more hot water. With the burner rating of 12,000 BTU (approx 4kw) and a recovery rate of 40L per hour, it's the fastest in the industry.

More convenience - All Suburban Water Heaters are designed for easy installation, operation and maintenance.  The limit switch and reset button are conveniently located in a housing behind the removable outer door.  The electric heat element and combination drain plug/anode rod are also located there, making service a breeze

Longer Life
 - Heated water attacks all metals, but not porcelain.  That's why Suburban uses a porcelain-lined, steel water heater tank with an anode rod to "absorb" the electrolytic action - just like your water heater at home. The 'sacrificial' anode should be checked yearly. Usually, last approx 2-3 years and then need replacement.

A wall panel switch electronically ignites (via 12V) and controls the water heater. The heater also includes a 1440W 230V element. For higher recovery, both the gas and electric element may be used simultaneously.
