Can the B2HA-399 be used with an indirect water heater?
Yes, the Vitodens 200-W B2HA-399 can provide domestic hot water when paired with a compatible indirect storage tank. The boiler's 2" supply and return connections support integration into larger hydronic heating and domestic hot water systems.
Can multiple Vitodens 200-W boilers be installed together?
Yes, up to eight Vitodens 200-W B2HA boilers can be combined in a cascade system for applications requiring greater heating capacity. The boilers are staged to match changing system demand while providing additional redundancy.
What is the difference between the B2HA-399 and the smaller Vitodens 200-W models?
The B2HA-399 provides substantially more heating capacity than the smaller B2HA models, with a 399,000 BTU maximum input and 323 MBH Net AHRI rating. Its larger 2" heating connections and higher 80 PSI operating pressure also make it suited to larger heating systems.
