We are looking for recommendations for a hybrid electric/propane tank-less water heater for our 99 Damon Challenger 310. We are looking for one that will run off of electricity when the bus is parked and set up and propane when dry camping or traveling. We currently have a 6 gallon electric/LP heater that really limits us when it comes to showers and washing dishes (works fine for one shower but we have to wait a while before washing dishes afterwards and even then not enough hot water to rinse). Does anyone have any experience that they can share which might point us in the right direction as far as brands, models and cost? Thanks in advance for your input!

When hooked up to AC power sourceTurn the electric AND propane on at same timeThat is fastest recovery rate.....roughly 16.2 gal/hr (based on 70*F water temp)Propane alone....roughly 10 gal/hr recovery rateAs for Hybrid TanklessI have no recommendation......here is a Review of 5 models

Heating water for "on demand" use requires an incredible amount of energy which must be available . . . . instantly. Look at the size of the gas burners that come with residential instant hot water heaters. It's not impossible with electricity, but not very conducive to RV use.I could easily see that requiring a 100 amp 120/240 volt service which would be unlikely in all but the most exclusive RV parks.Chum lee

There is no way to do an electric "on demand" heater. A 50 amp RV only has 12,000 watts available. Propane does work.I have a ten gallon electric/propane and it meets my needs.On pure electric it takes 90 minutes to first cycle. Then it recycles once every 4 hours for 15 minutes. It draws 1400 watts.I much prefer to run on electric--and save my propane.

^^^ Agreed. A few years ago I looked at doing an on demand electric at our house. Just the cost of the additional wire I needed to run made it a non-starter. On demand propane is a different deal. That's cheap and easy. Last year I bought a 3.2 GPM on demand propane for our deer camp, EBay, $64.00 delivered. Works great!
