so you are saying the heater is on the farther side

of the garage from the house. If the house has been there for many years, I don't think there is a risk of cold waterline gets frozen but you want to insulate the hot waterline to save some energy. You can buy pipe wrap insulation for the right size for your waterline.

Ideally the electric water heater should be in the house in northern states, but I don't think you can move it easily inside without incurring significant expenses of moving electric and water lines.

• 是。在远离房子的车库那一头。房子有70年了。water heater买来一直在车库。但是以前车库里有油罐，所以 -大鲸鱼- ♀ (308 bytes) () 10/13/2025 postreply 13:05:47
