Thermal Solutions has designed the Evolution® high efficiency copper-finned water heaters to meet the needs of today's commercial domestic hot water heating requirements.

The Evolution takes the very best of existing copper-finned water heater technology to the next level by incorporating a list of design features not found in competitors' products. Real-life serviceability, innovative heat exchanger design, clean and efficient advanced combustion, and unique timesaving controls are all combined in a compact, quick-connect package. The Evolution is truly a step above the rest.

Real-Life Serviceability
The Evolution is adaptable to virtually any installation. Rear connection ports and complete front and rear access to the unit's components and controls simplify side-by-side modular applications. When venting is a concern, the Evolution offers sealed (direct vent) and power vent options so the need to construct a costly chimney is eliminated. In addition, the easy setup and even easier maintenance make Evolution water heaters ideal for either retrofit or new construction projects.

Innovative Heat Exchanger Design
Central to the Evolution's highly efficient operation is the design of its copper-tube heat exchanger. Not only does it efficiently maintain heat transfer, but the innovative gasketless header allows easy inspection, cleaning and individual tube replacement. The combustion chamber is also completely enclosed in a stainless steel compartment and features collection/evaporation components to effectively handle cold-start condensate. Combining these features, the Evolution offers state-of-the-art heat transfer properties while effectively dealing with start-up condensate.

Clean and Efficient Advanced Combustion
Designed to operate with NOx ratings less than 10 ppm, the Evolution's noiseless ceramic radiant burner runs at minimal excess air levels creating highly efficient, trouble-free operation. The rugged, industrial-cast-aluminum blower and fan wheel are equipped with a replaceable combustion air filter (99% efficient to one micron) to create excellent combustion characteristics and even air distribution. There's no need for tricky pressurized compartments...the Evolution can even be operated with its jacket panels removed for easy inspection or maintenance.

Unique Timesaving Controls
Instead of using a series of relays, the Evolution utilizes state-of-the-art microprocessor flame safeguard controls to provide extensive diagnostic information including first-out fault annunciation using an LED diagnostic display. The proven spark-to-pilot ignition system ensures that the pilot is lit before allowing the main gas valve to open. The optional display unit, as shown at the left, can be easily incorporated to provide additional operational information and history.
