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. The dual coil line of Dunkirk's H2O indirect fired water heaters is a great addition to any hydronic heating system. Fast, efficient domestic hot water production is as simple as connecting an H2O to your boiler or solar heating system. With centralized connections on the top of the unit, setup is quick and easy. The H2OI115DEDK has a 115 gallon storage capacity and an impressive recovery time to make sure that you'll always have hot water when you need it. With an indirect-fired water heater, you can use your boiler's efficiency and power for domestic hot water in addition to space heating. When it comes to reliable, efficient water heating in a durable package, the H2O is a fantastic choice.
The H2OI115DEDK is built to last. H2O water heaters are wrapped in a thermoplastic jacket to prevent damage while stainless steel construction of the DHW 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 an indirect-fired water heater. Two and a quarter inches of expanded polystyrene insulation bring the H2O's standby loss under a half degree Fahrenheit per hour.
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.
Secondary Heat Exchanger
The H2OI115DEDK is a versatile piece of equipment. The secondary coil serves as a backup to the primary coil and can supplement water heating for high volume demands. Both coils may be connected to a solar system or your boiler. Heat source diversity means peace of mind that if one system malfunctions the other can pick up the slack.
Electric Backup Heater
A 3500 watt electric backup heater for handling small DHW loads is included for when your primary and secondary heat sources are unavailable. With the potential for three heat sources, the H2OI115DEDK provides unprecedented peace of mind.
