Hot Water Extravagance

When I'm doing a bit of washing, such as dirty hands or a few dishes, I tend to use a flow of warm water.  I got to wondering what wattage of an on-demand heater I'd need for my habit, in case there were large savings available by getting fussy about minimizing the flow.  I am rather appalled to see that I've been running something like 8,000 watts into my sink for decades.  That's like running five or six hair dryers flat out.  Thinking of it that way, I'm sure I'll do better.

I am not sure of your exact situation.  I put up an on demand LP heater..uses 2 D batteries for ignition...in my barn .  It does what I want it to do.

Hi Bob;  I've used propane on demand Paloma brand water heaters for 40 years now. They work awesome.   Mine have a standing pilot light.
The lower the flow the less propane you use. It will get hot and you'll need to mix in some cold.

I have no immediate plans to replace the water heater, I just got curious about my energy use.  I've usually set the taps to flush the cold water from the pipes fairly soon and continued to use that flow.  I should run the hot water on full to bring it in, and then really minimize the flow or use a container.  That will save both time and energy.

I used to love to run my wash hands under a stream of hot water after a hard job. It felt like a well earned reward to soak my battered hands in something nurturing and healing. I enjoyed doing dishes as my hands got clean and soaked. Now I have no running water, again, uugh, so am looking forward to it again hopefully. Perspectives are interesting. My Indian name might have been Running Water instead of Running Bear or some such thing lol.
