Send Your Existing Heater Information
Include the nameplate photo, manufacturer, full model, fuel type, BTU input and automation model. Add photos of plumbing, venting and pad space. Tell us whether you heat a pool, spa or both and whether the property has commercial equipment requirements.
Your installer should confirm gas sizing, electrical supply, water flow, clearances and plumbing changes before installation. A similar cabinet or BTU label does not establish direct fit.
Repair or Replace
If the heater has a confirmed component failure, compare the repair quote with replacement equipment and installation costs. Age, condition, exchanger damage and the availability of correct parts all affect that decision. Our heater parts guide helps you organize a model-specific parts request.
Warranty terms depend on the exact product, purchase channel and installation conditions. Request the applicable manufacturer terms before buying; package purchases do not automatically give every item the same warranty.
Important Jandy Purchase Notice: Jandy equipment requires professional installation. Confirm manufacturer warranty and support conditions before purchase. Electronic products are subject to Pool Supply Depot's non-returnable electronics policy.
Nationwide Shipping and Freight
Include your delivery ZIP code with your request. We confirm equipment availability, purchase options and shipping arrangements for your order. Large heaters, filters and equipment packages may require freight. Tell us whether the destination is residential or commercial and whether a liftgate or delivery appointment is needed. Local pickup is also available in Henderson, Nevada; confirm arrangements before visiting.
Questions Before Ordering
Will a larger heater always be the best choice?
The right selection depends on heat demand, desired heating time and the available infrastructure. Ask your installer to confirm sizing rather than selecting by BTU alone.
Can you help with a commercial heater?
Yes. Use our commercial and ASME heater page and include the project requirements with your quote request.
