Fast, on-demand heat in any weather. The right heater for spas and for owners who want warmth now, accepting a higher running cost.
Raypak is a long-established name in gas pool heating, and its digital gas heaters are a common, well-regarded sight on the equipment pad. A gas heater answers the heating question differently from a heat pump: it burns fuel to heat the water directly, which means fast, powerful, on-demand warmth in any weather, at a higher running cost.
Best for: Owners who want fast heat, especially for a spa, or who need heating independent of air temperature.
A gas heater burns natural gas or propane to heat pool water directly as it passes through. Because it generates heat rather than harvesting it from the air, it is fast and powerful, and its performance does not depend on the outdoor temperature. The Raypak digital gas heater pairs that capability with digital controls for precise temperature setting and automation compatibility.
Raypak engineers these heaters with durability in mind, including corrosion-resistant internal components, which matters for a heater's working life. For an owner who needs heat quickly and reliably, a quality gas heater like this is the proven tool.
The clearest case for a gas heater is a spa. A spa is meant to be enjoyed on a whim, warm water on a cool evening without hours of advance planning, and only a gas heater delivers that fast, on-demand heat. Any owner whose project includes a spa they intend to use spontaneously should look hard at gas heating.
A gas heater also suits owners who want to heat a pool quickly rather than gradually, who use the pool intermittently and want it warm on short notice, or who are in a climate or season cold enough that a heat pump struggles. Where a heat pump is the efficient choice for steady, season-long pool warmth, a gas heater is the choice for speed and independence from the weather.
Speed and power are the gas heater's defining strengths. It can bring a spa up to temperature quickly, and it can heat a pool fast when you want it warm for a specific occasion rather than kept warm all season. It does this in any weather, because it does not rely on warmth in the air.
The Raypak digital controls make temperature setting precise and allow the heater to be integrated with pool automation. For on-demand heat, especially spa heat, a gas heater is simply the right tool, and a well-built one is reliable and long-serving.
The defining trade-off of a gas heater is running cost. Every hour of heat has a fuel cost attached, and that cost rises with gas and propane prices. A gas heater used to keep a pool warm all season can be expensive to run, which is precisely why a heat pump is the better tool for that job. The smart pattern is to match the tool to the task: a heat pump, or solar, for efficient season-long pool warmth, and gas for fast, on-demand heat and for the spa.
A gas heater also requires a gas supply, natural gas or propane, and proper, code-compliant installation of the gas line, venting, and clearances. This is not a self-install component; it must be installed correctly and safely by a professional. Correct sizing to the pool or spa is, as always, essential.

Choose gas when you need fast, on-demand heat, especially for a spa, or heating independent of air temperature. Choose a heat pump for efficient, low-cost, season-long pool warmth. Many of the best projects use gas for the spa and a heat pump or solar for the pool.
A gas heater burns fuel to generate heat, so every hour of warmth has a fuel cost attached, and that cost rises with gas and propane prices. A heat pump moves existing heat rather than making it, which is far cheaper, though slower.
Yes, it is the right tool for a spa. A spa is meant to be enjoyed on a whim, and only a gas heater delivers the fast, on-demand heat that makes that possible. Heat pumps heat too gradually for spontaneous spa use.
No. A gas heater requires a gas supply and proper, code-compliant installation of the gas line, venting, and clearances. It must be installed correctly and safely by a professional.
