PRODUCT SPOTLIGHT

The Double Hybrid Heat Pump™

Our Double Hybrid Heat Pump is a modular heat pump air handler that integrates with existing radiators, hot water baseboard, radiant floors, and forced air systems for renewable heating and cooling.

✓ Adaptive hot water supply temperature allows old-school cast-iron radiators or oversized baseboard to deliver steady comfort without ripping out existing piping.

✓ Acoustic foam keeps the compressor whisper-quiet, even at peak load.

✓ Provides hot water or air for winter heating and chilled air for summer cooling with umatched efficiencies.

DOUBLE HYBRID HEAT PUMP

Deep Subcooling: The Double Hybrid Advantage

The advantage of the Double Hybrid Heat Pump comes from its engineering.  The unique refrigeration cycle process has several points of increased efficiency, resulting in better performance, with less stress on the system, and the bedrock of our industry-leading warranty.

CAPABILITIES

What Our System Delivers

Icon (14)

All-in-One Comfort

Heats and cools your home with a single system. No separate units, no compromises.

Icon (13)

Adaptable

Adapts seamlessly to radiators, baseboards, or ducts. Plug-and-play with your existing setup.

Icon (10)

Smart Hybrid Mode

Recovers energy from the refrigeration cycle and supplements hot water heating with hot air, improving efficiency and comfort at the same time.

Icon (12)

Dedicated Hot Water Heater

Produces all of a buildings DHW needs with up to 1/4 the energy of traditional water heaters.

Icon (1)

Backup Electric Heat

Integrated into every unit, but only used as a backup.

Icon (5)

Remote Monitoring

2-way connectivity enables real-time data collection, easier servicing, and ongoing energy tracking.

INTELLIGENT CONTROLS

Total System Command

Cloud-based monitoring and BMS-level environmental controls give building owners and operators real-time visibility into system performance, energy output, and zone management.

ADAPTIVE CYCLES

Smart Modes of Operation

The Double Hybrid Heat PumpTM is designed to work for a wide variety of types of buildings with several modes of heating operation:

Hybrid Mode (HY)

Operates as a hot water generator that automatically provides a small amount of supplemental heating by hot air.

Forced Air Mode (FA)

Operates as a standard forced air heat pump and can also maintain tank temperature for domestic or other hot water uses.

Cooling Mode (C)

Operates as a forced air heat pump, producing chilled air.

Cooling + Hot Water Mode (C+HW)

Simultaneously produces hot water and chilled air, resulting in higher overall efficiency. The hot water can be potable or non-potable.


There are several options for backup heat, including electric resistance hot water heat or electric strip heat for forced air systems. Energy Catalyst manufactures a buffer tank which includes (1) or (2) integrated 4.5kW electric elements for use as backup heat.

PRODUCT SPOTLIGHT

The Twister Geothermal Loop™

Proprietary ground loop technology with a 50+ year lifespan. The thermodynamic backbone of every Energy Catalyst system. Since 2010, over 2,000 Twister Geothermal Loops have been installed across the US.

50-Year Certified Lifespan

Advanced high-density polyethylene construction is non-reactive to ground elements and can outlive some buildings.

Enhanced Thermal Transfer

Twisted geometric layout increases contact surface area with standard backfill, generating more thermal energy from every foot of trench.

Rapid Installation Design

Optional Speed Twister option allows the use of a solid center pipe which can be connected directly to a grout pump, no tremi line needed.
