This heater is designed for use in spas and hot tubs with Hayward controls. It is a 5.5 kW heater, which means it can heat up to 550 gallons of water by 40 degrees Fahrenheit. The heater is made of stainless steel and has a flow-through design, which means that the water flows through the heater element directly. This helps to ensure that the water is heated evenly. The heater also has an Incoloy coated heater element, which is more resistant to corrosion than other types of heater elements.
The G7518 heater is a good choice for spas and hot tubs that need a reliable and efficient heater. It is also a relatively affordable option.
Here are some additional tips for choosing a hot tub heater:
- The size of the heater should be based on the size of the spa or hot tub. A rule of thumb is to get a heater that is rated for 1.5 kW per 100 gallons of water.
- The voltage of the heater should match the voltage of the spa or hot tub.
- The heater should be made of a durable material, such as stainless steel.
- The heater should have a flow-through design to ensure that the water is heated evenly.
- The heater should have an Incoloy coated heater element to resist corrosion.
