• Designed and built-in the USA Burner system features a radially fired, downward blowing, premixed burner with a negative pressure gas valve and plenum design, delivers a more stable flame under a wide range of operating conditions, including low gas pressure, wind and non-equal pressure zone terminations 316L flex heat exchanger floats freely and acts like a spring to accommodate all thermal shocks and stresses Heat exchanger made of 316L stainless steel for superior corrosion and erosion-resistance Self-descaling heat exchanger design prevents scale build-up Easy-access connections - thermostat/pump/outdoor reset Water inlet strainer - strainer included and factory installed on the units to deliver debris-free inlet water to the system Intelligent controls - units can be set to control temperature or allow maximum flow delivery - ideal for short duration demand spikes or large commercial dump loads tied with storage tanks, after every firing cycle, system circulates internally to equalize temperature, eliminate hotspots and prevent scale (pump models only) Units allow for maximum domestic hot water supply while simultaneously delivering up to 125000 Btu/hr of space heating with no three-way valve to fail Combines the commercially proven 316L flex heat exchanger and integral pump with a plate-type heat exchanger for seamless space heating Plastic vent temperature overshoot control maintains safe stack temperature below the vent's maximum temperature rating Simple install with self-learning and outdoor auto-reset for the most comfort and maximum savings Eliminates need for a primary/secondary loop setup and large space requirements of a boiler/storage tank installation No low loss header system needed Self-learning recirculation - use Intellihot under-sink valve, get instant hot water (eliminates water waste) for any application, zero flow-rate activation Heated buffer tank - integrated half-gallon buffer tank eliminates temperature spikes and cold-water sandwiches, +/- 2 deg F temperature stability Plate-type heat exchanger - dedicated ASME-rated, stainless brazed plate heat exchanger for space heating capable of up to 125,000 Btu/hr, separates domestic hot water from the space heating side to maintain safety and integrity of the domestic side Indoor, wall-hung, fully condensing and direct ignition SCH 40 PVC, SCH 40 CPVC, polypropylene, stainless steel venting materials

Provide endless hot water while maintaining a comfortable space temperature. In most combi boilers, hot water heating is an afterthought. Intellihot's combi models deliver a large quantity of hot water while simultaneously keeping your house comfortable. They elegantly combine domestic hot water and space heating with one unit, one gas line and one vent. Intellihot's combi models deliver a full quantity (200 MBH or 250 MBH) of domestic hot water when needed and easily modulate down to efficiently deliver up to 125 MBH of space heating.
