A friend of mine had a plumber install a small toekick hydronic heater a few years ago & it never ever worked properly. There is a regular old 50gal electric H2O heater next to the bathroom. The "plumber" put in 3/4, 3/4, 1/2 T in the top of the water heater. 3/4" cold enters from the top & 3/4" hot exits vertically. 1/2" parts exits (all in PEX) to a recirculator pump & then to the heater & returns on the 1/2" part of the cold Tee. There are shut valves on both the 1/2" hot & cold at the water heater.
anyway, there is some mixing of hot & cold now, do I need to put in some kind of check valve somehwere? mixing valve? she'd like to use the thing. this is in portland, oregon....
thanks in advance for any advice
