Water Heater

The HX2 is RECO Commercial Systems’ nextgeneration of compact, semi-instantaneous water heaters that can use steam or boiler water as the heating medium.

Hydro-Pneumatic Tanks

Reco CS hydro-pneumatic tanks are designed to store both water and compressed air. Without an internal bladder to separate the two, the compressed air is in direct contact with the stored water and acts to either absorb or exert pressure on the water. Storage up to 30,000 gallons.

Thermo Master Domestic Water Storage Heaters

By combining exact storage requirements for peak load demands with a forced circulation recovery section, the Thermomaster is excellent for commercial, industrial, and institutional service. Integral recirculation assures a full supply of hot water on demand.

Heat Exchangers

High quality components for optimal performance, engineered to meet specific steam needs for industrial and commercial facilities.

Replacement Tube

Available in single and double wall, in copper, copper-nickel and stainless steel, available in 2-pass, 4-pass.

Domestic Hot and Cold Water Storage Tanks

Standard tanks are carbon steel vessels with a 5 / 8 ” prime prime layer of cement, manufactured from NSF certified materials. It provides excellent, long-term protection and is fully field repairable.

Steam and Clean
Steam Generators

High quality components for optimal performance, engineered to meet specific steam needs for industrial and commercial facilities.

ASME Tanks and Vessels

Filter tanks, air receivers, blow down tanks, flash vessels, condensate tanks, and accumulator tanks, built to your specifications.


A fully packaged indirect-fired water heater that uses boiler water from a condensing boiler as the heating source. Utilizing a plate type heat exchanger, the system provides efficient heat transfer at boiler water temperatures.

Thermal Energy Storage

Thermal energy tanks are reservoirs for storing energy in chilled water cooling systems. Water has a better thermal transfer than air. Thermal energy storage has been around for decades and continues to prove an efficient and economical storage method.

We are The Water Heater and Pressure Vessel Experts

Since we built our first tank over 100 years ago, the RECO name has been synonymous with quality. Today we are recognized as one of the country’s leading suppliers of pressure vessels, water heaters and storage vessels, building to some of the most demanding engineering standards in the world.
