I should clarify that, we have the original Hydro Flame, and we discussed replacing it with a newer model heater, but a certified RV repairman recommended first trying to clean the original one up and see how it worked. He got it working and thought it was a good reliable heater, so basically he blew it out with a compressor and cleaned up any rust and debris. We haven't had a lot of time to test it, but it's nice and quiet and has fired up quickly on previuos at home tests. Sounds like we really need to heat up the thermo coupler in cold windy weather.
