Heater for Water cooled 914s, As promised, here are the pics Options

Here are the pics of the prototype. If there is any interest, this may be one of my next produts.

It hets pretty cold here in Michigan, its 26F right now and I do need a heater. I had a heater under my dash and I got tired of looking at it so I came up with this.

It uses the stuck heat/fan controls on the dash. The fan works in the usual way and the red heat director lever actuates the water control valve to control the temp of the heat exchanger.

Andys-
Yes, my heater lines run inside the longs back to the engine

Propricer-
Feel free to use my stuf in your book. Check out my website listed in my signature for my gaues and stuff.

I do not tap off the lines to the radiator for a couple of reasons.
I like to keep water going through the engine when the t stat is closed. You may have noticed the return hole on the block where the water pump was is usually blocked by the new coolant line fittings. Keeping coolant flowing through the engine always helps to prevent cavitation and aids in expelling any air pockets.

My water pump has a provision for a heater suction side and I come off of the engine in the stock location on the manifold. I also have a small return line from the high side to the low side to keep some coolant flowing even when the t stat and heater control valve are closed.

I was thinking of making a kit for this conversion, I will test it next week when I get back home.
