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.
Public-private partnership aims to boost the heat pump supply chain and support conditions for rapid market adoption with a set of targeted strategies.

To keep up with Gov. Newsom’s heat pump target, California needs to more than triple installations.
Most heat pumps in North America extract heat from outside air to warm interiors, which is why we call them "air-to-air" heat pumps. However, this term is incomplete, as heat pumps can also provide comfort without relying on forced air delivery.
