Challenge
• Long downtime between uses creates high storage costs
with large tanks
• Upsizing of natural gas lines and venting is difcult and
expensive
• Wide range of ow rates (0.5 GPM – 24 GPM) to feed up to
8 lavs, 8 showers, dishwasher and kitchen sink
• Need 70°F temperature rise
• Mechanical room located 100 ft from washrooms
Solutions
Eemax application engineers were engaged to specify the
system based on customer requirements. Tankless heaters are
piped in parallel then feed into a 120-gallon commercial tank
heater on a recirculation loop. The Eemax tankless units provide
heating when ow rate exceeds 4 GPM. The tank heater
provides hot water for the low ow needs and the recirculation
system. The result of pairing the tank and tankless heaters is
a best of both worlds solution minimizing storage losses while
delivering on-demand hot water.
