OVERVIEW
Imagine if anytime you wanted to take a dip in the pool-early in the season, late in the fall or just one evening after dark-your pool's temperature was perfect! Hayward's HeatPro Heat Pump, a high-efficiency heater, gives you the ideal water temperature while using less energy than natural gas heaters. It offers an alternative way to heat your pool that is safe, reliable, and energy efficient.

To heat your pool water efficiently, the HeatPro takes the heat from the surrounding air and uses it to warm the water in your pool eliminating wasted energy. Its digital LED control panel provides an easy-to-read digital temperature display, and shows diagnostic codes for quick identification of components that might need service.

Designed with the consumer in mind, the HeatPro's round base and compact footprint is ideal for retrofit replacements, allows for easy installation, and has integrated hurricane tie-downs to meet local codes. Also, adding value is its ArmourCoil protected heat exchanger, which allows the water passing through the system to be heated and returned to the pool. With its precision electronic temperature control, the perfect water temperature is constantly maintained, providing continued energy savings. The HeatPro Heat Pump can save you up to 80% on your heating costs, paying for itself in just one year. Why not save money, savor your backyard oasis and be environmentally conscience-all while staying cool.

Hayward HeatPro heat pumps incorporate titanium counter-flow heat exchangers for unrivaled and uncompromising performance even under the harshest conditions. Other key features include: heavy-duty, super-quiet scroll compressors; durable injection-molded UV-resistant body panels that are impervious to rust and deterioration; stainless steel hardware; and a polyethylene screen to protect the evaporator coil from damage. Plus, Hayward HeatPro heat pumps are lightweight, compact and easy to install or service, making them ideal for both new pools and spas and existing system upgrades.

JUst wondering what fautly codes are F 5 and LP HP?
Romeo on Feb 10, 2020
BEST ANSWER: Your owner's manual should have explanations for all of the display codes. You can find the owner's manual on the resources tab of the product pages.Here are the display code meaning from this heater's owner's manual.

F3: Unit currently in defrosting cycle (the fan works but the compressor is stopped). This is normal operation when outside temperatures are cold.

LP & LP3: Shortage of refrigerant gas in the unit or faulty low pressure control. The digital display will show LP3 after 3 LP faults and shut down your pool heater. The pool pump will also be stopped for protection if the unit’s internal time clock feature is used. If LP or LP3 occurs you should call for service.

HP & HP3: Low water fl ow to the unit or faulty high pressure control. Check water flow. Backwash filter and/or heater. The unit will show HP3 after 3 HP faults. This will stop your heater for protection.

Can't go wrong with a Hayward -
Arrived on time - Very easy to install - Only took me about 4 hours - Thought I would need help but after checking around and finding everyone wanting a couple thousand to do it I just decided to give it a go myself.

Works great, keeps my 16,000 gallon pool at 90 degree's without a pool cover -
