30-day money-back guarantee

Try ThermoSave in your home. If you're not happy with it for any reason, you can return it within 30 days of delivery for a refund of the product price.

Installed units are fine. You don't need to keep it in the box. Installing it is how you try it.

How to return

  1. Email support@thermosave.com within 30 days of delivery with your order number. We'll send you return instructions.
  2. Restore your water heater's original wiring, or have an electrician do it, before you remove the controller. Always turn off power at the breaker first.
  3. Ship the controller back, with the originally included accessories, using the instructions we send you.

What's refunded

  • We refund the product price to your original payment method within 5 business days after we receive the return.
  • Shipping is not refunded. The customer covers shipping in both directions: the original $8 shipping charge is not refunded, and you pay for return shipping. We will issue a return shipping label which will be deducted from your refund.
  • The unit should be returned without damage beyond normal installation and use.

Defects

If your ThermoSave stops working because of a defect, that's covered by our 2-Year Limited Hardware Warranty, and we pay shipping for valid warranty claims.
