Tank Less Water Heater
2009-06-15
Recently, people here in America are given an option to purchase and install tank-less water heater. But most of homes still use water heater with tank. It is still very new in Japan.
In Japan, I have never seen a house with tanked water heater. So, this is a picture from my parents home in Japan. They have tank-less water heater. It works great. I would like to have tank-less units in my house. However, we just upgraded our heater and duct this year to better than 95% efficiency one. So, the water heater must wait until next year.
