Lochinvar debuts air-to-water heat pump designed for year-round residential and light commercial use.
May 5, 2025
The new Centrus unit provides heating, cooling, and hot water from a compact system engineered for cold-weather performance and compatibility with standard North American components.
Last month, we discussed direct-to-load hydronic heat pump systems. These systems use a variable-speed compressor and circulator to adjust heat output and flow, eliminating the need for a buffer tank or hydraulic separator.
GSHP systems have one primary significant difference: the outdoor refrigerant coil and fan are absent. Instead of these components, the functions of the outdoor condenser have been integrated into the indoor unit, resulting in a hybrid condenser and evaporator unit.
The availability of heat pumps allows designers and installers of hydronic heating to include cooling. A simple method involves using a single air handler with a chilled water coil for a ducted distribution system, providing single zone cooling that can complement multi-zone hydronic heating in average houses.
The heat pump water heater (HPWH) market is set to grow from nearly $100 billion in 2024 to $156.59 billion by 2030, fueled by energy efficiency regulations, rising energy costs, urbanization, and a demand for sustainable solutions.
