Looking for recommendations for tankless water heaters. So many to choose from. We are full time 38 ft 5th wheel. Thanks in advance

You can get them in electric or propane variants.
- Electric struggles with creating enough heat to keep up with a decent flow of water. Think about it, if you have a 5gal/min flow rate, it needs to heat a 5 gal bucket of water from 50F to 120F in 1 minute. Most RV's and Campsite electric posts can't provide that kind of power, so you get derated units that are very marginal.
- We had a propane version on our boat and it struggled to match the heat output to the flow rate. Below a certain flow rate, it would shut down and you got cold water. Then when you opened up the valve, it would get scalding hot for a second before settling back only to get cold when you turned it back down. Unless you have unlimited water so you could just leave the water running at a continuous flow rate, it just didn't work.
