Bosch T520 HN LP Tankless Water Heater, Indoor Use

Q:How do you winterize your tankless water heater? The current plan is to install in a cabin where it drops below 10 F.Ron McGregor | Thursday, September 27, 2012

A:
If you are not planning on using the tankless water heater for long periods of time in the cold it is best to drain it completely so that the water inside doesn't freeze. Thanks for the question!
