Water Heater Maintenance Part 2 – Tankless Water Heaters

Maintenance of tankless propane water heaters is a little bit easier than their cousin the tank water heater that I covered before.  Some of the steps will be the same.  Such has removing power and propane prior to doing the cleaning.  Making sure the water is off and that you have a vacuum cleaner available.  The time frame for doing your cleaning will be the same and that would be prior to putting it into service for the first time in the camping season.  The reason being is that you want to make sure no critters or bugs have made it their home while it was in storage.
Start by inspecting the flue and hood areas.  Soot is a sign of incomplete combustion and if you find it start by cleaning everything in sight.  At this point if you haven’t found signs of bugs, then I would probably contact the repairman and have them check out the unit.  While you are in there cleaning, look for any signs of water leakage and give the pressure relief valve a quick open and close.  Unlike the tank systems, you won’t need to worry about pressure build up nor will you need to burb the tank to make sure you have the correct air bubble.
Now would be a good time to get some electrical contact cleaner like CRC and clean all of the power and electrical connections, including the battery for the RV.  When you are all done, it is time to turn on the water, fire up the unit and make sure everything is working as it should.  Then put your tools aware and enjoy the camping season.
