This geothermal heat pump delivers the comfort with hot water for your radiant or hydronic system. It can also help cut your costs for domestic hot water production.

If your needs extend to cooling, in some cases, this model’s innovative design can also work in conjunction with a hydronic air handler to utilize chilled water to produce cool air for your home in the summertime.

Like all Carrier® geothermal systems, it’s ENERGY STAR® qualified in all sizes. So, perhaps best of all is a Federal tax credit still available on geothermal systems. You can revel in getting a tax credit of up to 30% of your installed cost.
