EnviroSep SIWH, Semi-Instantaneous Water Heaters are specifically designed and manufactured for Hot Water Systems with intermittent loading. The system is designed to heat water, on-demand; and a small storage tank is utilized to buffer sudden surges, resulting in accuracy to +/- 3 deg F. An internal Circulation Pump is provided to obtain an even temperature profile throughout the tank volume. The EnviroSep SIWH, Semi-Instantaneous Water Heater may be manufactured to include a System Recirculation Pump, which is recommended for maintaining Hot Water Loop Temperature. Electrical controls may be provided with PLC programmable controllers or simple, relay logic.
