What is a pool heat pump?
A heat pump pool heater is a machine that uses a reversible high-pressure refrigerant system to heat or cool water. The refrigerant combines with warm air drawn in from the atmosphere to produce heat.
How do air-source pool heat pumps work?
“Air-source” implies that a heater sources its heat from the air in the environment. The heat transfer process takes advantage of heat’s natural ability to move from a high-temperature area to a lower one. Using a small amount of energy, air source pool heat pumps use a fan to harvest heat, and later distribute that heat into your pool water. The main components involved in the heat transfer process are the fan, evaporator coil, compressor and heat exchanger. Here’s a detailed explanation to give you a better idea:
The process starts when the fan draws in warm air from the environment and passes it through an evaporator coil. From there, the liquid refrigerant within the evaporator coil reacts with the air and forms a warm gas. The compressor then pressurizes the warm gas into a hot gas, and pumps it through a titanium tube located within the heat exchanger . This is actual heat transferring takes place.
At this point, the water from your pool flows through the heat exchanger and passes over the heated titanium tube. Two things happen during this exchange. The hot tube disperses its heat into the flowing water — at the same time, the water helps cool down the hot titanium tube, preventing it from overheating. Finally, the heated water is pumped back into the pool, and you enjoy the comfort of a refreshingly warm swim.
(On a side note: A reversing valve located near the compressor controls the direction of the refrigerant flow, which aids in both cooling and defrosting coils during colder temperatures.)
Imagine an air conditioner but in reverse.
Heat Pump COP
Air-source pool heat pumps heat your pool using a minimal amount of energy (up to 8 times less than gas heaters). In pool heating, this is referred to as a
COP or Coefficient of Performance. The average pool heat pump COP sits at about 6.0, producing 6 units of energy for every dollar spent, which is good.
That’s just a quick rundown of how pool heat pump COPs work – to learn more, check out our article on Coefficient of Performance
What is COP or Coefficient of Performance?
All pool heaters require a simple and easily identifiable way to gauge their performance in terms of energy use. This is where a coefficient of performance comes into play. A COP is a ratio that measures the amount of energy a heating/cooling appliance outputs to the amount it consumes. The formula for calculating a unit’s COP looks like this:
COP = ENERGY OUTPUT / ENERGY INPUT
$1.00 Energy In (Electricity Cost) = $8.00 Energy Out (8X the energy in-- you get $8.00 of pool heating energy for $1.00 in electricity cost!))
Heat Pump Pool Heaters extend your pool season and let you enjoy more time in the water.
Comfortable, warm, and completely at peace. Whether it’s mid-summer or early fall, your swimming pool heater turns frigid nights, into nightly swims, and chilly autumn mornings to refreshing morning dips.
Rheem is proud to introduce our new heat pump product line. Every Rheem heat pump comes standard with a Spiral Titanium Tube. The Classic Series heat pumps have been designed to meet the exacting needs of the pool and spa professional. Rheem offers a feature-rich entry-level heat pump, the Classic Series, which provides rock-solid performance at an affordable price.
The Classic Series can be easily controlled by most two-wire and three-wire remote systems. And for those big jobs and high-end pools, the Rheem Classic Heat Pump is the heat pump of choice. The heat pump also has On Board Diagnostics alerting the homeowner if there is a problem and provides the service technician with detailed diagnostic information.
Cabinet Exclusive DuraSteel™ Powder-Coated Cabinet
Polyester powder-coated, non-corrosive cabinet is more durable than plastic heat pump cabinets. Same rugged steel construction used by all the major air conditioner manufacturers
Large Air Coils
Raised lanced-fin design maximizes heating at lower temperatures. Rheem engineered coils are highly optimized to meet our specific design requirements. From the proper fins per inch to advanced distribution circuiting. We are the only heat pump pool heater company to actually manufacture our own coils.
Venturi Fan Cowling
High-capacity 3000-cfm fan provides unrestricted air flow for better heating. Precision engineered and manufactured cabinet design eliminates unwanted air gaps. This means more air over the coil which translates to greater efficiency
Scroll compressors are quiet and efficient compared to piston type compressors. They provide higher efficiency, lower sound levels, superior durability and unsurpassed reliability. The unique design of a scroll compressor actually wears in over time, not out!
Sound Isolation Pads
Prevents sound transfer to equipment pad and elevates the base pan to improve water drainage. Its the little details like this that make Rheem products stand out from the crowd.
Spiral Titanium Tube
Our spiral titanium tube heat exchanger provides a corrosion-free waterway that can withstand the abuses of harsh pool chemistry. The spiral tube helps reduce deposit build-up and increases efficiency by performing a “scoop-and-lift” action
Internal Bypass Valving
Automatically compensates for normal day-to-day changes in your pool’s hydraulics, maximizing heat transfer efficiency
Off-set 2” PVC union connections are included for ease of installation
Controls - Digital
Your digital heat pump pool heater can be set to have a different target temperature for your pool and spa. This allows you to dial in just the right spa temperature and never have to adjust it again. The pool can be set to a lower, more energy saving temperature
The digital heat pump pool heater can be easily controlled by most two-wire and three-wire remote systems
On Board Diagnostics
Tells the homeowner if there is a problem. Provides the service technician with detailed diagnostic information.
