Hydronic Air Source Heat Pumps


Hydronic air source heat pumps are a product proven in Europe but relatively new in North America.  They are comprised of a standard outdoor air source HP connected to our DX2W heat exchange module, buffer tank, aux backup boiler and control system.  They enable the use of economical and efficient air source heat pump technolgy as a means of heating or chilling water.  Ideal for hydronic floor heating & cooling applications as well as hot water radiation retrofits.  Air source hydronic heat pumps can also deliver forced air heating, dehumidification and cooling by using hydronc air handlers or fan coils.  ThermAtlantic can manufacture models to suit most residential and commercial applications.

A2W HP Configuration

ThermAtlantic has pioneered the use of this technology in Canada since 2009 which has resulted in a sophisticated controls package designed to manage water temperatures and heating loads effectively.  Hydronic air source heat pumps work well in moderate winter climates such as Atlantic Canada, the Eastern US seaboard, and the west coast of Canada.  They are not designed for areas with winter outdoor design temperatures much below -15'C or 5'F.  However, in areas where air source heat pumps are known to work well - so will hydronic models.  In many regions where winter climate is moderate it has been found that hydronic air source heat pumps are nearly as efficient as their geothermal counterprts - but at less than half the installed cost.
