Cleaver-Brooks HxO Tankless Instantaneous Water Heater

Using your new or existing hot-water heating loop, it delivers on-demand hot water by extracting heat from the boiler loop through a compact, efficient heat exchanger and transferring it to the cold domestic supply.

Alstrom Semi-Instantaneous Water Heaters

A proven, economical steam-to-water solution for central heating, service and process applications. Steam condenses in the shell and water is heated in the tubes; the small tube-side volume lets the steam control valve respond almost instantly to flow changes. Also available in water-to-water designs.
A unique stand design permits vertical or horizontal installation depending on available space, with easy tube-bundle replacement. Single- or double-tubesheet models suit most applications, including cross-non-contaminating requirements.
Alstrom Storage Tanks & Heaters

Designed for buildings where hot-water demand fluctuates or spikes suddenly. A 316 stainless-steel vertical or horizontal storage tank pairs with a heating section that can use steam, water, thermal fluid or other media — optionally with two circuits for two heating mediums — configured to each project’s demands. Superior 316 SS corrosion resistance extends system life at costs competitive with lined-tank systems.
