P-K COMPACT® semi-instantaneous water heaters perform reliably, providing long, trouble-free operation in thousands of installations. Its design, which focuses on small heaters that produce high volume output at a closely controlled temperature, makes it an ideal water heater for almost any building owner.

With our proprietary ANTICIPATOR® control system, the outlet temperature is continuously monitored so the system can immediately respond to hot water demand, even with fluctuating draws, to a close tolerance of ±4°F of set point. Constantly pumped circulation stabilizes temperature control at all draw rates, continually monitors water temperature, and prevents scale formation in most water conditions.
