Heatworks Technologies has a 6-year, full unit exchange warranty. If you need to file a warranty claim, you must contact support at in order to receive a return authorization form for the claim. No exchanges will be issued without a return authorization number issued by Heatworks. Return shipping for the original product is the responsibility of the customer, and all returned products must be wrapped and packaged securely to avoid shipping damage.

A replacement water heater will not ship without Heatworks first receiving and inspecting the returned product. All replacement water heaters will ship standard ground within 1 business day of Heatworks receiving the returned product.

If you choose to receive a replacement water heater prior to returning the original product, you will be invoiced for the replacement unit. The replacement unit will ship within one business day after payment. The original product should be returned to Heatworks within 7 business days of receiving the replacement water heater. Once the unit has been received by Heatworks, your credit card will be refunded for the invoiced amount. Refunds will not be processed after 14 days.

If you request expedited shipping, you will receive an invoice for the shipping cost. The replacement unit will ship within one business day after payment is received.
