Hayward H250FDN Universal H Series 250 000 BTU Pool and Spa Heater Natural Gas Low Nox

Before you buy: H250FDN Universal H-Series

This listing is the 250,000 BTU natural gas unit (model H250FDN). The H-Series line spans multiple capacities and fuel types, so check that both the BTU size and “Natural Gas” match your setup before ordering; a propane or differently sized model is a separate part number.

Checks before ordering

• Fuel supply: natural gas only. Propane versions carry different model codes.
• Capacity choice: H-Series sizes step up and down from this one. If your pool or spa needs a different BTU rating, do not assume this unit substitutes.
• Footprint: listing data shows 29 in x 28 in x 24 in at 165 lb. Confirm pad space and delivery access.

Not included / separate

The listing indicates one heater (1 item). Gas piping, venting, unions or adapters for your plumbing, electrical connections and controls are not shown as included. Gas installation should be performed by qualified professionals per local code.
