Quick facts
Bosch EHK electric heater kits install in the Bosch BVA air handlers used with Bosch IDS central heat pumps. They warm the air already moving through the ducts when the heat pump needs extra heat. Five outputs are available, from 5 to 20 kW, and each heating element is protected by its own circuit breaker.
Five outputs listed by Bosch
The Bosch specifications for the BVA 15 and BVA 2.0 air handlers show which outputs suit each size. The 5, 7.5 and 10 kW kits have a single element and a single circuit; the 15 and 20 kW kits have two.
The kits and their air handlers
- EHK-05B (5 kW), EHK-08B (7.5 kW) and EHK-10B (10 kW): sizes 24, 36, 48 and 60
- EHK-15B (15 kW): sizes 36, 48 and 60

Before ordering
Note the full model number on the air handler’s nameplate. The MCA and maximum fuse or breaker size vary with the air handler size and series: they are listed in the Bosch specifications. Bosch also notes that a heat pump system needs a specified airflow, 350 to 450 CFM per ton of cooling.
