How to choose a GAS Heater

Gas pool heaters are the fastest way to heat your pool or spa, allowing you to swim all year round and raise the temperature on demand.

Choosing the Right Size

Consider your pool or spa size, desired swimming temperature, and local climate. Larger systems heat faster but come with higher running costs. For example:

A 200MJ Heater: Heats a 5,000-liter spa by 12°C in just over 2 hours.

A 300MJ Heater: Does the same in 1.5 hours.

A 400MJ Heater: Reduces the time to around 1 hour.

Running Costs

A 200MJ gas heater uses 200 MegaJoules of gas per hour. In Sydney, gas costs around 2.5c/MJ, so running a 200MJ heater for an hour costs $5.

Reducing Costs

Spas lose heat through evaporation. Using a cover can significantly reduce heat loss and the time your heater needs to run, saving you money.

Why should i get a gas heater for my spa rather than a heat pump?

When choosing between a gas heater and an electric heater for your pool depends on several factors, including efficiency, cost, and personal preferences. Here are some reasons why you might opt for a gas heater over an electric one:

Faster Heating: Gas heaters can raise the temperature of your pool water more quickly than electric heaters. This is particularly useful if you want to use your pool on short notice or extend your swimming season.
Cost-Effective for Short-Term Use: If you only use your pool occasionally, gas heaters can be more cost-effective in the short term because they heat the water quickly, reducing the amount of time the heater needs to run.
Performance in Cold Weather: Gas heaters perform well in colder weather, making them a good choice if you live in a cooler climate or want to use your pool year-round.
Independence from Electrical Grid: Gas heaters do not rely on electricity, which can be beneficial in areas prone to power outages or if you want to avoid high electricity bills.
Lower Upfront Costs: Generally, gas heaters have a lower initial purchase price compared to electric heat pumps. This can make them a more attractive option if you are looking to minimize your initial investment.
Versatility and Compatibility: Gas heaters can work well with any type of pool and existing gas lines, offering more flexibility in installation and usage.
Energy Efficiency for Quick Heating: While gas heaters might not be as energy-efficient over long periods, their efficiency for quick heating can be advantageous, especially for sporadic use.
