Frequently Asked Questions

How do I drain an Eccotemp tankless water heater?

Turn off the gas and water supply. Attach a hose to the hot and cold service ports (or inlet/outlet) and flush with compressed air or a pump through the cold inlet while the hot side drains. Refer to your model’s service manual for the specific port locations on your unit.

Why do I need to drain my propane tankless water heater?

Draining is needed for winterizing before freezing temperatures, for descaling the heat exchanger, before servicing internal components, or when storing a portable unit. Allowing water to freeze inside a tankless heater can crack the heat exchanger and cause expensive damage.

How often should a tankless water heater be drained and flushed?

Descaling (vinegar flush) once a year is recommended in hard water areas. In areas with soft water, every 2–3 years is typical. Always drain the unit before storing it in freezing temperatures, even if a full flush is not needed.

Can I use vinegar to flush my tankless water heater?

Yes — food-grade white vinegar is the standard descaling solution. Pump it through the heat exchanger using a submersible pump and two hoses connected to the service ports. Run it for 45–60 minutes, then flush thoroughly with clean water before returning the unit to service.

What happens if I don’t drain my tankless water heater before winter?

If water freezes inside the heat exchanger, it expands and can crack the copper tubing, causing an irreparable leak. Most manufacturers void warranties for freeze damage. Always drain outdoor or unheated-space units before the first hard freeze of the season.
