Heat Pump Water Heater
Innovative heat pump water heater producing high-temperature hot water at 60–65°C by extracting heat from the air. Saves up to 75% energy, using 4 times less electricity than conventional heaters, while providing cool air to ventilate surrounding areas.
“Turn ambient air into high-temperature hot water and massive energy savings.”
PAC Heatralized is a Heat Pump Water Heater designed for large-scale high-temperature hot water production. By extracting heat from the air, it serves hotels, hospitals, and businesses with continuous hot water needs, reducing energy consumption and long-term costs.
Reduces hot water electricity costs by 70–75% or 4 times compared to conventional electric heaters, while providing free cool air.
Save up to 4 times more on electricity
than conventional water heaters.
Receive free circulating cool air
to help regulate the surrounding temperature.
Produces hot water
at temperatures up to 60–65°C
Supports immediate replacement
or integration with existing tanks
0⃣1⃣ – PAC Heatralized absorbs heat from the air through an Evaporator Coil, causing the refrigerant to change from a liquid to a gas before being sent to the Compressor.
0⃣2⃣ – The Compressor compresses the refrigerant to increase its pressure and temperature.
0⃣3⃣ – The heated refrigerant is sent to a Heat Exchanger to transfer heat to the water system, producing hot water at temperatures up to 60-65°C.
0⃣4⃣ – Hot water is sent to a Water Tank for storage and future use.
“PAC Heatralized absorbs heat from the surrounding atmosphere to generate high-temperature hot water, cutting energy costs by up to 75% and providing free cool air as a by-product.”
Centralized hot water systems for hotels, or individual units for villas and bungalows with bathtubs.
Hot water for patient rooms, spas, wellness centers, and hydrotherapy systems.
Hot water systems for industrial factories with high demand, replacing old systems and reducing energy use.
Hot water for showers in clubhouses, golf courses, and sports centers.
"For me, family time is always precious. Choosing to install PAC Pooltemper was the perfect solution. The problem of water being too cold is gone, as the unit can adjust for both warm and cool water in one system. Most importantly, my daughter loves it. Installing this unit has truly fulfilled our happiness and created perfect moments for our home."
“Previously, we hardly used the pool because the water was quite cold. But after installing the PAC Pooltemper, my children and I use the pool more often. We swim more frequently and have many more family activities together.”
“I previously used Frenergy at home and saw real electricity savings, so I decided to use it for my hotel. It helps manage the hotel's hot water and energy systems more efficiently.”
“Previously, we used electric heaters for hot water in the guest rooms. Since the resort switched to PAC Frenergy, electricity consumption dropped from 880,000 kWh/year to only 171,000 kWh/year.”
“My Koh Chang Paradise Resort has used PAC Frenergy for over 10 years. Now that I have expanded to Koh Kood, I continue to choose PAC products, selecting the latest technology: PAC Hybrid Solar. It is a solar-powered VRF air conditioner that truly helps us save energy and electricity costs.”
“No more worries with PAC Pooltemper. The machine quality is excellent; no breakdowns or frequent repairs. It is perfect for our business.”
“At Khum Sameing, we have a Japanese-style Onsen in a Thai Lanna atmosphere, equipped with PAC Pooltemper which can reach water temperatures up to 50°C. In the guest rooms, we installed PAC Frenergy and PAC EcoAire, which have helped us save a lot of energy. Additionally, I chose PAC products for my IWRM water plant in Phan Thong, Chonburi. We are very satisfied with PAC's innovations.”
Over 500 organizations nationwide choose PAC solutions for hospitals, hotels, industries, and various other sectors.




















A: PAC Heatralized uses a Titanium Heat Exchanger, which can be used with poor quality water or even water that stainless steel cannot withstand due to corrosion.
A: Not necessarily. The PAC Heatralized Compact model is designed for smaller systems, such as use in hotels or condominiums with one unit per room.
A: Axial Fans can draw more energy from the environment. Combined with a large evaporator coil area, this ensures high efficiency in extracting heat from the atmosphere.
A: With Electrophoretic evaporator protection, coil corrosion resistance is enhanced. Combined with a stainless steel structure, PAC Heatralized can operate in all conditions.
A: With a Tube-in-Tube Heat Exchanger, the condenser can operate under low water flow conditions while maintaining high heat exchange efficiency, unlike conventional plate condensers.
A: Both PAC Absolutt and PAC Heatralized are Heat Pumps. However, PAC Absolutt is an all-in-one Heat Pump that comes with a built-in hot water tank, providing convenience without needing an additional tank for systems with moderate hot water demand.
