Before you buy a new pool heater, there are several factors to consider. The size and style of your pool will determine the kind of pool heater you need. Choosing the right heater also depends on how much power it will need. If you have an above-ground pool, you should look for a saltwater-specific heater. These two factors are often used together, and a heater with both functions is the best choice for a saltwater pool.
A gas-powered heater is best for in-ground pools with a small water volume. These heaters can heat pools up to 15,000 gallons. These heaters can be purchased from any home improvement retailer or manufacturer. The manufacturer’s warranty will guarantee the product for five years from the date of purchase. The heater’s price depends on the fuel source, and the gas price depends on supply and demand.
