Joe can you tell me if it is common practice to run hot coolant from the engine straight into the hot water tank heat exchanger and from the there into the engines heat exchanger. For some reason whoever set my system up put a “t” in the engines hot coolant line before the engines heat exchanger and ran one hose to the hot water heater and the other Hose of the “t” to the engine’s heat exchanger. The exit hose from the hot water heater is lead to a spigot in the Engines coolant tank. That setup does not provide efficient hot water unless i use a flow control valve in the exit hose from the engines heat exchanger.
