Aston Single Hydronic units are engineered for hot water needs such as pool/spa heating, radiant floor, snow melt, aquaculture, and process water installations. Units can be selected as heating only or heating/cooling models. Scroll compressors, R-410A refrigerant, and oversized heat exchangers combine to provide users with exceptional energy savings while straightforward controls make operation easy.



The Aston Hydronic unit cabinet is fabricated from heavy gauge steel with a durable metallic finish for long lasting beauty and protection. Control panels that can be placed on either end allow piping to be located on the front or at the back and improve serviceability.


Powerful Aurora controls offer two-way communication between components, industry-leading operating logic, and thorough troubleshooting capabilities. Optional upgrades add true energy and refrigeration monitoring capabilities and more.

Insulated Coaxial Heat Exchanger

Aston Single Hydronic heat exchangers are coated with our exclusive ThermaShield foam insulation. ThemaShield increases both efficiency and consistency of the heat exchangers while robotic application ensures an even airtight seal.


High efficiency scroll compressors are used to reduce operating costs and provide years of reliable operation. Sound attenuating compressor blankets and double isolation mounting plates are used in every unit for quiet operation.

Hot Water Assist

Larger Aston Single Hydronic units can include a hot water assist function to provide supplemental heating of domestic water while simultaneously proving space heating (depending on the application).


All GeoStar units use R-410A - an environmentally friendly, non-ozone-depleting refrigerant that enhances efficiency and savings.
