Pros and Cons of Tankless water heaters in RV
Thank you for your replies if any.
Forum Discussion
I have a tankless system at both of my remote properties in AK: served by well and / or rainwater catchment. Temperature of the supply water can run between 35 and probably 60. One of the tankless heaters has an electronically adjustable water temp, the other requires a manual plug-n-play to change the delivered water temp.
If one wants to do a lot of shutting off and restarting during use, this is not the system to have. If one has a limited supply of water, this is not the system to have.
However, if there is not a significant limit on water, I believe tankless are actually more cost-efficient (considering cost of gas and electricity) than keeping a 20 gallon or larger tank full of hot water. 6 - 10 gallon? IDK.
All that being said, we use our tankless heaters without the "way too hot or way too cold problem" (IMO, that's a mixing valve issue at the point of delivery) and without any problem with cold intervals...but when we shower with the tankless heaters, we let the water run for about 2-3 minutes before getting in and we keep it going until through with the shower. Similar exercise if we're using how water for other tasks. We have not had problems in either location where the tankless heater is fed by varying volume / pressure of water (i.e. both our locations are served by pumps, either from the well or from the rainwater basin).
Might not be the best application for a typical RV, but there could be some benefits for some situations.
