Now that my stove is finished (see pics in "Homemade" section) I am trying to get my parts list together for my plumbing fittings.
My system will consist of OWB about 50' from the house, 20-plate HX for DHW and water-to-air hx in the plenum of my upflow furnace.
Pump will be mounted in the basement near the furnace and water heater. OWB will be the high point of system, and I am guessing there will be a difference of 6-7 feet from the high and low points of the system.
Was wondering:
Where should I place ball valves on the system? I thought it might be a good idea to have them on all the hx ports to facilitate removal/replacement but without a "union" type fitting to break the piping down, do they do any good? I figured I would need ball valves on the supply and return line out on the stove also, of course.
What about fill/drain ports and/or bleeder valves? Was planning on doing most of the filling through the top of the stove (2" pipe) but wondered if I needed a hose bib or something on a line down in the basement, that I could use to prime the system?
Any thoughts or advice on the tricks you have learned on plumbing are most welcome.
Here is a pic of my equipment in the basement:
