Aftermarket heater question.

Does anyone make an underdash heater that is electrical and does not require hoses from the water neck.

I have to ask... why would you want to do this? Are you just trying to keep the engine compartment cleaner and hose-free? The heaters in these trucks are so simple, and so is the wiring... Why add something that will unnecessarily complicate things... So to be a pain, but I am curious what the goal is in doing this.

I got rid of my A/C and Heater then smoothed the firewall. I would not mind 2 hoses running but if i could keep it to just a few wires then i will. I only want a small heater to defrost and for the really cold days. I would not use if but a few days a year.

I was looking into this.

I bought a 72 without any of the heater or blower motor stuff under the dash, and well it gets cold here in Chicago. Instead of trying to find all the misc parts i need, i think i will eventually get something like what is in the link above. Its relatively cheap.

From JC's item descritpion;
"Installation is a snap with several mounting options available. Hot water in the cooling system provides the necessary warmth using 140 CFM air flow and 12,000 BTU output. Quiet operation. Includes 3-way switch, wiring/hardware anf instructions. Order optional plenum (sold separately; SKU# ZX519991R) for defroster function."


I couldn't see how an electric heater of any nature would not overtax the charging system. Heaters draw a lot of current. Without upgrades to the charging system, it may be a choice between headlights or heat at given time.

Best bet is to rum the hoses and get a heater kit, rather than an electric heater.

Coolant heater VS electric heaters are going to be night and day difference.

did not think about the electrical system being strained... I think ill go with the vintage air hidden one then. That Mojave one looks like an option also.

you know that they sell electrical heaters at harbor freith for less than $10.00 all you have to do is plug it on the ligther and they work ok for me
