Quick facts
EHIA electric heater kits are field installed in Dettson Duotec series air handlers. They provide backup heat for a central heat pump by warming the duct air. The Duotec specifications list single-phase kits from 5 to 25 kW; this page groups the 10, 15, 20 and 25 kW models.
Actual output depends on voltage
The kit’s documentation gives its actual output at 240 V and at 208 V. The EHIA10KN10, for example, delivers 9.6 kW at 240 V and 7.2 kW at 208 V. The 10 kW model connects to a terminal block, with no breaker; the 15, 20 and 25 kW models have built-in circuit breakers.
One or several circuits
- EHIA10KN10: one circuit
- EHIA15KB10 and EHIA20KB10: one circuit or two
- EHIA25KB10: one circuit or three
