This option allows you to run hydronic heating from an Espar or Webasto hydronic heater if you have our ProAir 12V A/C kit that features the 981 Evaporator.
This includes a hydronic heating coil that fits in the 981 evaporator cabinet, featuring two 5/8" ports. It also includes a replacement thermostat that allows the Heat function.
Your control board and wiring is already pre-wired for a heat output, and features a 10A activation relay on the control board.
If purchased at the time of purchasing your 12V A/C kit, we will install the heater coil in the evaporator for you at no additional charge.
