Features to consider

Heat pumps are the most efficient products from Raypak pool heaters. Heat pumps are already dominant in their product range. There are two basic and two additional categories of Raypak pool heat pumps and we are going to review them in a nutshell.

Some features are common to all Raypak heat pump models. The DuraSteel corrosion resistant housing is polyester powder-coated, and better than plastic one. Heat exchanger with spiral titanium tube is built-in for more power and durability. Units are equipped with direct-set dual thermostat for pool and spa temperature settings and LED diagnostic lights.

Compact series

Raypak pool heaters from Compact series, and its models R2350ti, R3350ti and R4350ti, are designed for above ground pools and smaller in ground pools. The maximum heat outputs are 50K, 66K and 83K BTU, respectively. As an orientation, reviewing the user experience, we can conclude that they are satisfied with 66K BTU heater for 12.000-gallon pool and 83K BTU unit can handle the 16.000-gallon pool if the weather is warm enough. The prices for the compact series model are between $1900 and $2600.

Classic series

Classic series, models R5350ti, R6350ti and R8350ti are more powerful units for larger pools, with maximum 95K, 117K and 133K BTUs. Compared to compact heaters, these models have slightly better coefficient of performance, caused by internal bypass valve. If you need a heat /cool model, look for letters -HC at the end of the model name. The prices of classic series models are between $2950 and $3395, but be ready to add $1000 to the heater price for heat / cool option (April 2017).

Quiet series

Quiet series are actually improved classic series, with about the same price range. The R5350ti-QT, R6350ti-QT and R8350ti-QT are designed for climates with salt air. Cabinet and parts are specially protected. The label “quiet” means that units are really quiet for this type of heater with only 59dB of sound.

Specialty series

Specialty series are not directly important for homeowners, but worth to know the option exists. Pool heaters are for professionals only. Units are based upon Classic series, with some customizable features to fit the special consumer needs.
