I've had a paloma legacy tankless water heater at the cabin for the last 12 yrs and have never been happy with it. it has never consistently provided hot water, most of the time it is really just warm water. the pilot light has also always been a pain in the rear. I've descaled it multiple times, rebuilt the water/propane valve, adjusted everything that can be adjusted multiple times. now I'm thinking I will just replace it. went to Susitna energy and they recommended Bosch therm 520. when I start looking at reviews of tankless water heaters it seems like they all can have the same problems I'm having now and I would hate to go to the trouble of replacing it and wind up in the same situation. the bosch heaters don't get real good reviews on line but I am always skeptical of online reviews.
can anybody give a good report on a tankless water heater that they use at their cabin? we have a well and our pressure tank is set at 30-50psi. we are using propane for the heater, would prefer a heater that doesn't require electricity to operate but could do it if is was worth it.
