Heating Appliances

The API Developer Programme is compatible with all Vaillant Group gas boilers that support the ebus protocoll. Generally speaking, all condensing boilers from the Vaillant Group that were produced after 2008 support the ebus. While supporting single heating circuit systems, the API Developer Programme will soon be enhanced to cover heat pumps and multi-heating circuits systems.
