POOL & SPA HEAT

Experience the luxury of total comfort with Hayward's full line of heating solutions. Never let the weather control your swimming pool and spa enjoyment again. Pool heaters provide the ultimate in swimming comfort letting you choose the perfect temperature all year round. Hayward has the best heating solutions for your backyard.

Gas Heat or Heat Pump?

Whatever your climate, warmer or cooler, you will want to experience the comfort of heating your pool.
Even if the air temperature seems warm enough, it doesn't necessarily mean your pool's water is comfortable enough to swim in.

The only way to continuously enjoy your pool is to heat the water to the perfect temperature,
there are pool and spa heating solutions for every application, budget and climate - let's explore them.

Gas Pool & Spa Heat

The greatest benefit of the gas pool and spa heaters is that they heat your pool and spa in minutes or hours versus the hours or days required initially to warm the pool with a heat pump. Gas heat is ideal if you don't use your pool or spa on a daily basis, and just want to heat your pool or spa as needed. Key attributes of Hayward's gas pool heaters are that they're environmentally responsible and lower the cost of ownership via their energy efficiency and reliability.

Another benefit of gas pool heaters is they perform well in any climate. They'll heat your pool and spa on the coldest of days versus the limits of a heat pump.

Advantages

Ideal for intermittent swimming
Maintains any temperature regardless of the weather
Quickest way to heat your pool or spa
Lower operating cost for intermittent heating

Drawbacks

Higher operating cost to maintain pool temperature in most regions

To determine your pool’s surface area in square feet, use diagrams below.

In the chart below, locate the surface area that is equal to or just greater than your pools surface area. Select the Universal H-Series model that is closest to your pool surface size.

The reference table below lists the time required in minutes to raise the temperature of the spa by 30°F. First, determine your spa capacity in gallons (surface area x average depth x 7.5). In the table, locate the column with the spa size in gallons closest to yours. The Universal H-Series models listed will indicate the approximate time needed to raise the spa temperature to 30°F.

		SPA/HOT TUB SIZE IN GALLONS
		200	300	400	500	600	700	800	900	1,000
MODELS	BTU/HR	Time in minutes to raise spa temperature 30° F

Our range of heat pumps at a glance:

HYDRAHEAT INVERTER HEAT PUMP

• DC Inverter Technology adjusts its power and electricity consumption based on the needs of the pool.
• Variable Speed Fan adjusts its speed according to the air temperature and operates at very low speed for a very quiet night time mode.
• Digital Colour Touchscreen Interface shows real time power consumption for immediate feedback & control.
• Soft Start Technology allows the heater to start from 0˚, and gradually work up to a higher speed, allowing for a stable current, and lower energy consumption.
• Designed to operate at low ambient temperatures (down to -̊7 ) in spring, and well through Autumn, the HydraHeat inverter allows you to extend your swimming season.

Heat Pump Pool

Heat pumps are incredibly energy efficient at maintaining a constant water temperature and can deliver savings of up to 70% versus a gas heater. Heat pumps are very efficient because they utilize the heat from the surrounding air to heat the pool's water versus burning natural gas or propane.

Heat pumps work well in warmer climates but are at a disadvantage in colder climates. Although a heat pump will operate at temperatures above 50° F, cooler air temperatures above 50° F may not have sufficient heat in the air to keep your pool as warm as you desire. At these lower temperatures, a heat pump is likely not the best option for heating your pool.

A Hayward heat pump model is the most efficient way to heat or cool the temperature of your pool or spa. Warmer climates and especially pools and spas with dark surface finishes benefit from the water being cooled. If you live in a climate that can become extremely hot the heat/cool heat pump is a perfect choice.
