Key Features

Hybrid Heat Pump + Gas Heating Technology

The UltraTemp ETi combines a high-performance heat pump with a gas-fired heater in one system, giving customers the ability to heat efficiently, heat quickly, or use both technologies together depending on their needs.

Four Selectable Heating Modes

Choose from Heat Pump Only, Gas Only, Hybrid, or Dual mode. This gives pool owners flexible control over operating cost, heat-up speed, and comfort.

Dual Mode for Maximum Heat Output

In Dual mode, the heater can operate the heat pump and gas heater at the same time, helping deliver faster heat-up performance when quick temperature recovery is needed.

Hybrid Mode for Smart Efficiency

In Hybrid mode, the heater uses onboard intelligence to determine an efficient and practical heating strategy based on the selected temperature difference and heating time period.

Natural Gas 220K Model

Pentair model 460969 is factory-configured for Natural Gas operation and is listed as the 220K UltraTemp ETi Hybrid Heater. This model is not field-convertible to propane, so the fuel type should be confirmed before ordering.

93% Thermal Efficiency Gas Engine

The gas-fired portion of the heater is listed at 93% thermal efficiency when tested under the applicable ANSI / CSA standard, giving it higher efficiency than many standard gas pool heaters.

TitanTough™ Direct-Fire Titanium Gas Heat Exchanger

The TitanTough™ titanium heat exchanger is designed for long service life and corrosion-resistant performance in demanding pool and spa environments.

Automation Ready

The UltraTemp ETi Hybrid Heater is compatible with Pentair automation systems, allowing convenient temperature control and system integration when paired with compatible Pentair controls.

Internal Water Bypass Assembly

A dual internal water bypass assembly automatically adjusts for water flows up to 120 GPM, reducing the need for an external water bypass in many properly designed installations.
