Every month, join us for in-depth training and discussion on application and design for modern hydronics technology coupled with geothermal heat pumps.
Hosted by John Seigenthaler

Comparing Air-to-Water Heat Pumps to Ductless Mini Splits (August 21 • 12-1pm CDT)
While the market for ductless mini-splits has grown recently, they aren’t necessarily the best option for many projects. August’s Modern Hydronics & Heat Pumps webinar will compare the costs and capabilities between ductless mini-splits and an Enertech air-to-water system in the same 5-zone residential project. The results may surprise you!
- Features air-to-water heat pumps provide that ductless mini-split systems can’t.
- How to configure an air-to-water heat pump with a heat recovery ventilator.
- Cost comparisons between systems that provide space heating, cooling, domestic water heating, and ventilation.
