Loop is Ephoca’s modern interpretation of the water-source heat pump-crafted into a low-profile, whisper-quiet room console with the performance and refinement expected of Italian engineering.
Loop is a quiet, efficient heating and cooling system for new and existing buildings, using a neutral-temperature water loop to reduce energy use, construction, and disruption while improving comfort and long-term property value.
Loop replaces radiators with compact water-source heat pump consoles that connect to existing hydronic piping, minimizing construction and disruption.
Loop uses a neutral-temperature water loop and room-level heat pump consoles to enable independent comfort control, simultaneous heating and cooling, and support for electrification and renewables.
Loop is more than a WSHP upgrade—it’s a pathway to a quieter, cleaner, more efficient future for your building and its residents.
Maintains water at ~60–90°F year-round, reducing energy demand and operating costs.
Allows bidirectional loop balancing using stable underground thermal sources for heating and cooling.

Heating and cooling without pipe replacement or invasive construction.
The LOOP Water-Source Heat Pump (WSHP) system requires a stable, well-balanced condenser water loop to maximize system efficiency and minimize operating cost. Maintaining loop temperatures within an optimal operating range (typically ~60–90°F) can be achieved using several proven strategies:
Also referred to as ambient temperature district energy or 5th-generation district heating and cooling, these systems operate at low loop temperatures and allow heat sharing between buildings. Waste heat from sources such as supermarkets, data rooms, offices, or industrial processes can be recovered and redistributed into the loop—often at little or no cost—improving overall system efficiency and enabling heat recovery–driven decarbonization.
Groundwater wells or vertical geothermal borefields provide a highly stable thermal source/sink with near-constant year-round temperatures. These systems enable bidirectional loop balancing (heat rejection in summer, heat injection in winter) and can significantly reduce or eliminate the need for boilers and cooling towers while operating on 100% renewable thermal energy.
A hybrid loop conditioning system combines multiple energy sources and heat rejection methods to maintain stable condenser water loop temperatures. Solar thermal collectors are used to inject heat into the loop during heating-dominant periods, while evaporative cooling towers reject excess heat during cooling-dominant periods. Photovoltaic (PV) systems can be integrated to offset the electrical load of the heat pump serving the loop. This hybrid configuration reduces overall energy consumption while improving system resilience, redundancy, and operational flexibility.
An air-source, air-to-water heat pump is used as a central loop conditioning device, adding or rejecting heat to maintain loop temperature setpoints. Because the loop operates at moderate temperatures, the AWHP achieves high seasonal COP, significantly reducing boiler and cooling tower runtime.
Both deliver the same variable-speed comfort and hydronic compatibility.

Loop is a water-source heat pump (WSHP) system that uses a closed water circuit maintained at a moderate temperature to deliver efficient, room-by-room comfort.
Loop circulates water at a moderate temperature through existing piping, while compact water-source heat pumps in each room independently heat or cool the space by drawing energy from, or releasing energy back into, the Loop.
Loop is available in Horizontal or Vertical Models. The horizontal model is designed for under-window and low-profile wall applications, delivering high performance in a compact footprint. The Vertical model offers a slim, upright configuration ideal for tight spaces where floor area is limited but performance expectations remain high.
Traditional systems rely on high-temperature heating water and separate cooling systems, often requiring insulated piping and invasive upgrades. Loop operates year-round at a neutral temperature (~60–90°F), enabling efficient heating and cooling using existing piping with minimal disruption.
