How much do hot tub heaters cost?

Hot tub heaters vary in price, depending on several factors, such as the brand, material quality, product specifications, and unique features. In most cases, you can expect to spend between $150 to $400 for a hot tub replacement heater. 

The good news is that spa heaters typically last a few years, so you don’t have to spend hundreds of dollars replacing your heater annually. Like spa jets, hot tub heaters don’t need to be replaced nearly as often as filters.
