Part of my quest to go total electric is figuring out ways to heat water without burning propane. A few years ago I mounted a large black pipe on the roof of Minnie and let the sun heat my water. It works quite well when I have good sun and it’s not too cold out. The only problem is that you have to use the water late in the day and long before the sun goes down. If you wait too long, the water cools quickly to an unusable temperature. In the cold days of winter, it’s sponge baths or burn propane for a shower. I longed for an occasional shower right before bed without burning propane.
I started exploring small electric hot water tanks that are made to mount under the kitchen sink and give you instant hot water without waiting for delivery through long pipes from the main hot water tank. These tanks usually hold only 3 gallons of supply and recover quickly. I found a prime deal of 20% off on one and ordered it for a Christmas present to me.
I puzzled over where to mount the unit and came to the conclusion that pulling the propane water heater out and installing it in the same place would be easy and give me hot water to all my sinks and shower.
I spent the last two days disconnecting the old unit and installing the new electric one. Parts here in Quartzsite are twice what they cost at Home Depot, but the hardware store is close and had Sharkbite connectors I like to use. Four connectors and a propane plug cost me almost $50.
I have been testing it out today and I think it’s going to work fine. With all my batteries and solar, heating the water only uses a small percentage of my power. I timed my shower and came up with 4.5 minutes of hot water. That’s plenty for me( I don’t spend much time washing my hair). The only thing that concerns me is the fact that it takes 1850 watts of power when heating. That’s almost maxing out my inverter. The specs said 1500 watts. I’ll have to be careful to turn everything else off when I use it.
As with everything I tinker with, I’ll undoubtedly find out more as I use it. I’ll try to update how it’s working in a later post.
