Dunkirk is one of the most established names in hydronic heating. Their reputation has been built over the years by ingenious design and perpetual innovation. H2O buffer tanks are the perfect remedy for short cycling. If your home or business is zoned, then your boiler may be producing too much heat when there is only a demand from a small zone. Likewise, if you live an environment with large temperature fluctuations, then your boiler may be producing more heat than you need on warm days. The H2OBT402WCDK allows for additional water in your system, which absorbs and stores excess heat until it is needed. The stored heat is applied to future heating demands, preventing short cycling and improving the efficiency of your system.
H2O buffer tanks can be used with boilers, heat pumps, or chillers. Whether you are working with hot water or cold water, an H2O buffer tank is an elegant solution to short cycling.
The H2OBT402WCDK is built to last. H2O buffer tanks are wrapped in a thermoplastic jacket to prevent damage while stainless steel construction of the tank prevents damaging corrosion and keeps your water supply clean.
Standby heat loss is one of the quickest ways to negate the energy savings of a buffer tank. Two and a quarter inches of expanded polystyrene insulation bring the H2O's standby loss under a half degree Fahrenheit per hour.
Heat Exchanger Coil
This buffer tank includes a heat exchanger coil. The heat exchanger coil can be used to complement the heating or cooling process. It may be connected to a solar system or boiler for supplementary heat, or in chiller systems, the coil can extract ambient heat from the water. Either way, the result is increased energy efficiency for your system.
Advanced Heat Exchanger Design
Dunkirk uses a smooth heat exchanger coil with a large diameter for the H2O line. These design elements prevent buildup that inhibits heat transfer. Stainless steel was selected as the material for its corrosion resistance. The result is an efficient, low-maintenance heat exchanger.
