Description

Product Overview

The Hayward Universal H-Series W3H150FDP is a compact, high-efficiency propane (LP) gas pool & spa heaterengineered for fast heat-up and long-term reliability. Designed with Low NOx emissions and broad installation flexibility, it’s a strong choice for modern equipment pads—especially where corrosion resistance and service access matter.

Ideal For

  • In-ground pools and spas needing dependable heating with a 150,000 BTU heater

  • Installations requiring Low NOx compliance (common in regulated air-quality regions)

  • Saltwater pools or challenging water conditions where corrosion resistance is a priority

  • Replacing older heaters where you want a modern, compact footprint and easier service access

Key Features

  • 150,000 BTU heating performance

  • Fuel Type: Propane (LP)

  • Low NOx design for environmentally responsible operation

  • Cupro-nickel heat exchanger for excellent saltwater and chemical corrosion resistance

  • “Universal” installation flexibility (designed to simplify replacement installs on many existing pads)

  • Digital control panel for temperature readout and built-in diagnostics

  • Electronic ignition (no standing pilot)

  • Hydraulic design intended to reduce pressure drop and help improve overall circulation efficiency

Benefits

  • Faster heat-up so the pool/spa reaches set temperature sooner

  • More durable exchanger performance in harsh water environments (salt/challenging chemistry)

  • Lower emissions with Low NOx operation

  • Easier ownership with digital diagnostics and service-friendly access

Customer-Facing Q&A

Q: What type of gas does this heater use?
A: This model is Propane (LP).

Q: What does “Low NOx” mean?
A: Low NOx refers to reduced nitrogen oxide emissions, designed to meet stricter air-quality requirements in many areas.

Q: Is this good for saltwater pools?
A: Yes—this heater uses a cupro-nickel heat exchanger, which is commonly chosen for improved corrosion resistance in saltwater and demanding water conditions.

Q: Does it have a pilot light?
A: No—this heater uses electronic ignition.

Q: Is it hard to service?
A: The Universal H-Series is designed with service-friendly access and a digital interface that supports troubleshooting and diagnostics.
