Here's a diagram: (best viewed with a fixed-width font) WATER HEATER : : : : engine......____L___/___L____......heat exchanger (to engine) Of course, the heat exchanger is mounted on the engine, but it's hard to loop with these text diagrams Here ... and : are hoses, _L_ is a T and _/_ is a valve. I have no valves between the _L_ and the heat exchanger. Are you sure about that? Water hoses and passages are BIG, not the tiny hoses to the water heater. The heat exchanger is directly on the engine on the Perkins looks hooked directly to the block passages. I don't think you have to put a loop hose on it if you don't have a water heater.... Granted it's late, but I don't really get what you're saying so I must not have made myself clear. The Heat exchanger is on the engine, and the only reason the loop is there is because of the water heater. That would seem stupid, to me. Water heater hoses should be like car heater hoses. The engine outlet to the water heater comes from the high- side of the thermostat, which pressurizes the water to the water heater. The low side of the water heater return should go into the suction side of the heat exchanger back into the engine, giving you hot water BEFORE the thermostat opens. Hrm. I'll have to check on how mine is set up. I'll guess your setup is right. I think mine goes into the suction side of the heat exchanger, so I probably have the same setup. mickey |
