I have my DHW connected to my coal stove. The water comes out of the bottom of the tank into the coal stove and returns to the top of the water tank. This is the way the manufacturer recommends the installation.
This works great while no one is using any water in the home. After circulating many times, the tank warms up.The problem is when someone uses the shower, make up water enters the bottom of the tank. This cold water goes into the coal stove (it only has one loop) so it doesn't have enough time to warm up. When it returns to the top of the tank, I'm actually dumping cold water on hot water and I can hear my wife screaming in the shower!
Is there a better way to do this? Maybe routing it in the opposite direction? (I have a circulating pump in line).
Thanks in advance.
