What Hayward Pool Heat Pump Models are Available?

Different heat pumps are offered for different applications.

Do you have an in-ground or above-ground pool?  

First let's look at Hayward for in-ground pools:

Heat Pumps for In-Ground Pools:

There are two main Hayward models for in-ground applications.

1. Summit
2. HeatPro

Summit is one of Hayward's in-ground pool heat pump.  Note the following important features:

HeatPro was a model formerly manufactured by EUS and is now in the Hayward family of products.  Below are the most important features of the HeatPro product:

• Comes in six different sizes ranging from 65,000 - 140,000 Btu/hr (see below to understand how this equates to pool size).
• The HP21104TC model is designed for operation in colder weather.  It is important to know that pool heat pumps need auxiliary heat if utilized in weather conditions below 40 F.
• Also contains a scroll compressor, sound cover, UV treated plastic casing, dual temperature control, and titanium enhanced heat exchanger like the Summit model.

Heat Pumps for Above-Ground Pools:

Hayward uses the same technology as that used for their in-ground offering, but specially manufactured for an above ground pool.  Below are a few features worthy of note:

• It is only available in one size 50,000 Btu/hr.  This is typically recommended only for pools that are less than 13,000 gallons in capacity.
• Contains a titanium enhanced heat exchanger which promotes high efficiency and anti-corrosion.
• Contains a scroll compressor and sound blanket for noise-reduction.
• Polypropylene casing to ensure that the Hayward pool heat pump does not rust.

What Hayward Model Would Provide Enough Heat for My Pool?

Select the Hayward pool heat pump model from the list below. Note that the low number is the heat output on a 50 F day and the high number is the heat output on a 80 F day. So if you see yourself swimming on a 50 F day, then use the lower number. If not, use the higher number:

Below also is a general recommendation guide that will help you determine what Hayward pool heat pump fits your pool volume:

The above information should give you give you what you need to select the correct Hayward pool heat pump model.

If you don't mind spend a little more up front to ensure that you get enough heat, buy a model that is one step larger than recommended. It's usually better to be safe than sorry!

This does come with a caveat.

If the heat pump is too large, it will turn on and off more often. When this happens, its reduces the life of the largest component, the compressor.

How Much Will It Cost to Operate?

Here is the big question! How much? Well, it all depends on how much your electric utility charges you for electricity.

The table below assumes that you are charged 11 cents per kilowatt-hour. If you want to find out exactly how much it costs to operate your heat pump, divide the value in the table below by 11 and multiply by however many cents per kilowatt-hour that your utility company charges.

Very important to save on operating cost: I highly recommend the use of a pool cover. It is useful even if you don't heat your pool. However, it is essential if you do. A pool cover can save you up to 50% on your operating costs. Also, since you don't have to operate it as often, it also prolongs the life of your Hayward pool heat pump.

Does Hayward Make a Quality Product?

At this section of every review page I give the manufacturer a 1 to 10 rating. 1 is low quality, 5 is average and 10 is high quality:

Quality Rating: 7

Hayward does a fine job protecting its own equipment so as to prolong its life. Note the following heat pump protection features:

1) Refrigerant high pressure cutout. This feature turns the heat pump off if the refrigerant pressure gets too high. This protects the compressor from overheating. It also protects the refrigerant piping from springing a leak.

2) Loss of refrigerant detection. This feature protects the compressor from running hard and it also protects your wallet. A refrigerant leak requires a certified technician to come and re-charge your heat pump.

3) Defrost cycle. This feature allows the heat pump to run through a defrost cycle in case the evaporator begins to freeze. Frozen evaporators result from running the heat pump in cold weather. This defrost cycle protects your equipment in weather between 45-55 F.

4) High water temperature cutout. High water temperature cutout protects more than just the piping and seals on your pool. It protects the innocent swimmer from getting burned. Huge plus!

5) Fan moter failure cutout. If the fan on the heat pump fails, the entire heat pump shuts down. Heat cannot be transferred into the pool water without this vital component.

6) Low ambient temperature cutout. As mentioned above, the evaporator will freeze and your heat pump will be ruined if it is allowed to operate below approximately 45 F. The Hayward pool heat pump automatically shuts down if you try running it in cold weather.

What Actions Void the Warranty?

Who wants to call the manufacturer for warranty protection, only to find out that your warranty was voided because of a technicality? The following actions include but are not limited to reasons that your warranty could be voided:

1) Sprinkler Damage. If you place your Hayward pool heat pump within distance of a sprinkler head's spray, this will void warranty.

2) Damage caused by salt or sand spray. If you are near the ocean, you may want to think about installing a barrier to protect from salt or sand spray.

3) Water flow from the filter pump operating outside the range specified. See the table below to ensure that you are within the design flowrate. All of the Hayward models mentioned above are design to support flow between 30 and 75 gallons per minute.

4) Blocking air flow. Do not place objects on top of the heat pump. Also, regularly clean debris caught between the guard and the evaporator fins.

5) Negligence, accident, freezing, installation in corrosive environments, conditions beyond the normal intended use, or acts of God. This statement comes directly from Hayward's statement of warranty.

6) Unapproved labor or service. If service is performed by somebody other than that approved by Hayward the warranty is void. This cannot be overemphasized. If your heat pump is still in warranty, contact Hayward!

7) Not filling out warranty registration card. Don't forget to fill out the form in the back of you user's manual!

I See A Diagnostic Code Flashing on My Hayward Heat Pump. What Does It Mean?

The digital panel on the Hayward pool heat pump uses diagnostic codes to assist a technician in determining problems with the heat pump. The following tables indicates the meaning of various codes.

A quick note: EUS pool heat pumps, also know as Energy Utilization Systems, was purchased by Hayward a few years back. So if you have been looking for EUS, here it is!
