The Benefits of Non-Pressurized Tanks

Traditional, pressurized tanks are bulky, expensive and inefficient. While they’re commonplace throughout the country, there’s an attractive alternative that many commercial and residential heating system owners aren’t aware of: non-pressurized water storage systems.

These non-pressurized storage systems fit easily through standard doorways and other entrances, making for easy delivery. They’re also fast to install. When they’re operating, you enjoy a more efficient, less expensive hot water system.

You also enjoy options. Choose the right R-value of insulation, for use with the heat source that best fits your needs, from solar thermal, biomass, combined heat and power (CHP) and others. At Hydroflex, our services are focused on you, the customer. We provide the products that meet your unique heat storage needs.
