Yes, you could...as long as there is a standard outlet. However, 4 gallons isn't much for showering. I'd go with a 20gal, but that's me.

Sufficient for supply hot water in rv shower.

Asked by Sunny January 5, 2021
4
Answers

I installed this unit in an outdoor kitchen and it provides plenty of hot water. Something to consider is the temp of the incoming water supply. If you empty the tank while showering and the incoming water supply is very cold, the unit may not heat it enough to complete your shower.

what is the nipple female size for the tops? What size faucet hose opening will be needed?

Asked by Javi January 4, 2021

Answers

1/2" female pipe thread. Standard faucet flex hoses don't have enough threads on them, but a 1/2" shut off valve fits nicely.

I can’t even wash my hair without running out of hot water. There’s no way it produces 4 gallons....

Asked by Coco November 9, 2020

Answers

Check your water pressure and temp you have heater set...mine is in RV...water pressure 45-50 psi and temp is set at 140...can take shower leaving water running and have plenty of hot water

Can I hook this to my existing hot water heater system in my RV Do I need to buy extensions for the existing water lines

Asked by Garvinslone October 9, 2020
5
Answers

Yes, you could hook this up to your RV water heater. However, if you ever camp where there are no electrical hookups, I would suggest having this unit ahead of your combination LP/electric water heater, or hook them up in parallel with isolation valves so that each can be used independently if necessary. And yes you will probably need to extend some water lines or have some connecting lines between the 2 water heaters to accomplish this.

Im not sure what size fittings to get or what size pex to use?

Asked by Liz July 15, 2020
3
Answers

The water heater has 1/2" male iron pipe connections, you will want to adapt to it using 1/2" female adapters and use 1/2" Pex. Anything larger would be a waste.

This is the second W/H we have purchased. Great for under the sink, instant hot water. This last one we installed by the washing machine. These new washers have to have hot water before they will work. Only 4 gallon capacity. But it is fast to reheat the water. Washer is in temporary in shed while home is being considered.

Only installed for about 10 days now. It's working great. Instant hot water. I placed this unit in my shop inside of a base cabinet about 200' from house. Having hot water out there is a must when working with tools, cleaning game, fish, etc.
