Tankless stuff again
I am entertaining the idea of a supplemental water heater.
A few details in my situation that I've not read about here. I live alone.
I have 32 solar panels and a solar water system, both of which work well.
I earn $2000 a year as a licensed solar power plant in Maryland, so the less electricity I use, the more I earn.
The distance from current solar and back-up high efficiency water heater to my shower is about 60', with pipes running thru crawl space.
I take about 10 minute showers.
My only energy source is electric and I am NOT going to introduce another means or bill to support a water heater.
I use cold water for everything but showering.
It takes a good 10 - 15 minutes to flush the cold water out of the pipes for a hot shower in the winter. Summer, not so long.
I've thought about an insta hot type thing under the bathroom counter, but wondered if the electric were still so inefficient that the on demand thing would surge and draw a huge amount of power. Similar to a self-cleaning oven?
My plumber also suggested a small, marine type water heater.
Would the constant heating of a marine tank draw too much power?
My water is hot, no doubt about it. It just takes too long to get to the shower and I hate wasting that much water!
Any ideas would be welcome. Thanks!
