Hi folks I really need some help here. I'm thinking I may have a few issues but let's start with the most pressing issue. Last summer we had a repair man out to tell us why the heater (Raypak 266) wasn't working properly. Well he took a couple panels off and after breaking the thermostat which he never did replace he told us we needed a new heater. I am a very handy person so I asked WHY? He told me that the heat exchanger was plugged with scale. What he never told me or rather wouldn't tell me was HOW to remove the scale. I took apart the manifold and he was right. There was one tube that was almost clogged with scale. I managed to get it partially opened up and the heater worked fine all the rest of the season. New season rolls around and after getting the water balanced for Ph hardness and chlorine I fired up the heater. The poor devil ( 4 years old) started right up, got very hot than shut down. I shut it down and tried again a few hours later only to have the same issue. It will start up, run for 20 minutes or so and shut off. After an hour or so it will fire back up again but never long enough to really warm the pool up. I'm thinking the root cause is build up of scale in the exchanger but just how do I completely (or close to completely) remove the scale? I can remove the exchanger but I don't know what I can soak it in once there is flow.
I'm going out there right now to check my Unitherm Governor and the pressure bypass switches but since I replaced both just last summer I'm thinking it isn't going to make a difference.
Ideas please!!!! I'll be honest with you, I hate swimming but even worse I hate working on this beast that never seems to stop breaking down I need help please!
