Started on replumbing the basement and adding a secondary loop to the furnace heat exchanger.

I’m also adding a 20 plate to the hot water heater so I have plenty of hot water for washing equipment. Also have the thirty plate for the snow melt.

Question is this, is there a wrong way to mount a flat plate heat exchanger?

Currently the snow melt is mounted vertically which works fine. Taco says not to mount one of theirs horizontally with the ports up as it may clog easier with sediment and voiding any warranty.

What would work best for me in the space I have and working around some things I don’t plan on moving or changing would be to mount the flat plates horizontally with the ports down. Only drawback I can see is might be a heck of a place to trap some air and resulting in a lock.


Any favored mounting positions amongst the people who deal with this daily and why?

We try to lay them sideways or vertical. Outlets down should not be a problem on 20 or 30 plate with as much flow as you have. It's those tall ones I'd worry about. You got the right idea, it's air lock and sediment you need to be cautious about.

Agreed. ports should be horizontal.

Here is a pic of one slim did on a job.

The installation paperwork for all my plates (3) say to keep the ports horizontal. The actual position of the plate itself can be horizontal or vertical but flows are to oppose each other.
