How to Heat Water Efficiently

Filed Under Information 

You're here on this site most likely because you're researching tankless hot water heaters. As I emphasize on this website, they are not for everyone. There is a significant up-front cost made all the greater because in many (most?) cases you would need to increase the capacity of your gas or electric lines. The electric heaters place a heavy burden on the power grid during peak hours, so paradoxically may not help with overall energy savings for the society. (More about this in several places here on this site.)

So simply saving energy with your existing hot water system is a reasonable option for many people. This article reprinted below from the US Department of Energy links to several pages on its website that gives you more tips on reducing your hot water usage, lowering your water's temperature, and so on. Used by permission.

I specially like the document listed at the very bottom of this page – that little link that says "PDF 161 kb." It's a bulletin from the renowned non-profit group, the Rocky Mountain Institute. As it's about 15 years old, some details must have changed, but the general information is good. You can open it in a new browser window or tab, or you can download it – it's a PDF format document.
