Diversified Heat Transfer has introduced the SPM Series Indirect-Fired, Semi-Instantaneous Boiler Water-Fired Water Heater with Integral Mixing Valve. This fully packaged water heater combines a high-efficiency double-wall plate and frame heat exchanger, an integral digital mixing valve, and an electronic PID control system into a single package. By integrating the water heater and thermostatic mixing valve into one solution, the SPM Series reduces mechanical room space requirements, simplifies commissioning, and reduces the number of building automation system control points required compared to traditional systems that use separate water heaters and mixing valves.

The SPM Series continuously monitors demand and automatically adjusts performance to maintain accurate outlet water temperatures under varying load conditions. It can produce up to 200 GPM of domestic hot water and is compatible with medium-, normal-, and low-temperature condensing boiler systems.
