Many legacy hydronic heating systems use a fossil fuel boiler to supply fin-tube baseboard heat emitters in some areas of a building and lower-temperature radiant panels in other areas. 

Government planners, taking their queues from politicians and advocacy organizations, have steered the future of energy supply away from fossil fuels and toward renewably-sourced electricity. It’s happening on every level from the feds right down to local city councils.

More and more hydronic heating and cooling systems are being designed around air-to-water and water-to-water (geothermal) heat pumps. When the heating distribution system is extensively zoned, a buffer tank is typically installed between the heat pump and that distribution system.

Last month, we discussed the role of buffer tanks in combination with air-to-water and water-to-water heat pumps that operate as “on/off” devices. The key concept was to turn the heat pump on and off based on changes in the buffer tank temperatures and not based on thermostats calling for heat.

Last month, we began discussing the HVAC system installed at my church’s newly-constructed parsonage. In this month’s column, we’ll complete the picture.

Find out about piping options for retrofitting an air-to-water heat pump into an existing hydronic system.

There is a growing interest in adding air-to-water heat pumps to existing hydronic heating systems. While I support their use, I do not recommend replacing a perfectly good cast-iron boiler that still has a long service life.

In rural upstate New York, residents harvest trees for firewood using chainsaws and hydraulic splitters. I burn about two face cords annually in my wood stove, enjoying its warmth during winter and relying on it during power outages caused by outdated utility lines.

I attended a conference hosted by the Building Performance Association and presented on air-to-water heat pump systems. Many professionals were interested in heat pumps, especially ductless air-to-air systems. One person mentioned the difficulty of finding qualified installers for air-to-water heat pumps and noted the higher cost compared to ductless air-to-air systems.

Air-to-water heat pumps and water-to-water geothermal heat pumps provide warm water for space heating, domestic water heating, and chilled water for cooling. Switching a hydronic heat pump system from space heating to cooling and vice versa seasonally is relatively simple. The system operating mode is changed at the thermostat or a dedicated system mode switch with heat, off, and cool settings.

As natural gas rates increase and the push for more sustainable energy sources intensifies, heat pump water heaters appear poised for massive growth. States such as California and Massachusetts already have regulations prohibiting or disincentivizing gas water heaters in new construction, and New York City recently enacted similar restrictions for new construction. So, are heat pump water heaters the future of the water heating market? Maybe or maybe not — but some industry experts certainly think so.
