ProSeries XTP Tankless Electric Water Heater

Jan. 27, 2023
Eemax's tankless water heater generates water temperatures up to 180°F (82°C) and flow rates from 0.5 to 20 gal/min (19 to 75 L/min).

Ideal for diverse commercial applications that require reliable hot water, the ProSeries XTP generates water temperatures up to 180°F (82°C) and specified flow rates from 0.5 to 20 gal/min (19 to 75 L/min) meeting the needs of both front and back of the house operations. The product family features 10 models in either 3 or 6 heating chamber configurations, and Eemax patented Adaptive Stability Technology (AST) to assess the heater conditions and shift the unit operation to ensure a consistent and reliable output.


AST monitors and assesses set temperature, flow rate, inlet and outlet water temperatures, and shifts heater performance to ensure consistent and reliable output. It also allows for faster time-to-temperature—simultaneously minimizing overshoot and undershoot (+/- 1°Fof the set temperature under steady state flow). Three functions are used by: AST Flex Power, AST Dynamic Power, and AST Smart Calibration.


Ready to install right out of the box, XTP is compact and can be mounted on a wall in small spaces; a single person can position, mount, and lock the heater into place while the inlet and outlet water fittings (3/4-in. NPT) suit common plumbing connections of a single or cold or hot water line. Since the electric water heater does not require venting, there's no need for wall vent penetrations saving installation time and wall space.


With corrosion and rust-minimizing, powder-coated, galvanized steel, stainless steel heating chambers, and copper-sheathed heating elements, the exterior cover is IP25-rated and prevents water leakage within the system (safe drainage and minimal corrosion).
