DIAMOND PLAN: The Eccotemp Diamond Protection Plan gives you extended peace of mind. With the purchase of the Eccotemp Diamond Protection Plan, you'll receive 36 months of extended warranty coverage. During your period of coverage Eccotemp will provide priority support, power surge protection, and unlimited parts replacements. Not only does the Eccotemp Diamond Protection Plan cover replacement of the heat exchanger and replacement of parts due to freeze damage, but it also covers one replacement of product accessories per agreement. The average cost of repairs without extended warranty coverage is over $200, but the Eccotemp Diamond Protection Plan covers 100% of the costs associated with repairs. Additionally, should you need to send your product in for an inspection or repair, the Eccotemp Diamond Protection Plan covers round-trip shipping and waives the cost of any labor necessary to repair your product. If your product cannot be repaired, the Eccotemp Diamond Protection Plan covers a one-time replacement of your product. Additionally, in the event of a natural disaster or other unforeseen circumstances, the Eccotemp Diamond Plan offers "acts of God" coverage that covers repair and/or replacement of your product.
