i have a customer who wants to put 20kw heat in their gas package unit.
its a 8 yo grandaire and she can not afford the gas right now so the landlord wants me to install electric heat in the supply plenum............
i have two questions,
1.) where do i look for a purpose built heater kit?
2.) wouldnt it be better to install it in the return air plenum?
i need 20kw heat in two stages 5-10-5 and cant seem to find any conclusive
literature on such product. if the coil is placed in the supply plenum would moisture compromise the elements? is there a better way? the unit is fine not perfect but sustainable.
thanks for any help or advice ,
