Hi, this is my first post. Im new to wood burning and just installed my new Woodmaster 4400. This is a great site and you have all been a great help. The OWB has been in use for roughly a week and is great for heating. My problem is with the hot water. I have a Plate exchanger that came with the wood burner 20 or 30 plate? I installed a mixing valve due to young children. One problem is the recirc. line for instant hot water to fixtures will not siphon with the mixing valve I believe because of the check valve. I bypassed the mixing valve and it circulates as normal. The next thing is the exchanger does not produce hot water warm at best. I believed this was due to low water usage but I have run several gallons through the system to heat the tank, and still cant seem to get hot water. Also my wife said that when she took a shower this morning it started out hot and got cooler. The pipe on the outlet of exchanger seems to be getting very hot so this isnt making sense to me. I was thinking of adding a pump for DHW or maybe a side arm exchanger. Has anyone else had this problem or suggest a solution. And has anyone installed a mixing valve with a recirc. line. I would appreciate any input before my wife makes me turn the water heater back on. Hope this all makes sense, see attached picture. Thanks
