How Variable Refrigerant Flow Systems Maximize Heat to Heat Water

Published on: June 1, 2019

Variable Refrigerant Flow Systems

Variable refrigerant flow systems can be used for more than simply heating and cooling the air in your home. They can be used to heat your water as well! VRF hot water modules are becoming more and more popular with homeowners across the Southeastern US. You might want to consider installing one of these modules in your home. We’ve previously discussed how VRF systems work; now we’ll take the time to explain how variable refrigerant flow systems maximize heat to heat water.

VRF technology has progressed over the last several years. Your VRF unit can now be modified to heat up your home’s water. Designated hot water modules can be added to your VRF system to collect hot water that can be used in your home.

VRF Benefits

Variable refrigerant flow hot water modules are occasionally referred to as HEX or booster units. They are designed to absorb heat directly from the water (or refrigerant) loop it is connected to. Simply put, it can use the VRF technology to heat water for your home’s use.

When the unit is in cooling mode, heat that is extracted from inside your home can be used to heat water. When the unit is in heating mode, some of the heat pulled from the air will be used to heat water, while the rest will be used to heat your home.

These modules do not take up a lot of space and are typically connected directly to the outdoor unit of your variable refrigerant flow system. In addition, they will also share the load with any of your indoor units.

VRF  Unit

If you currently have a VRF system installed in your home or are thinking of installing one when you replace your current heating and cooling system, you may want to consider adding on a hot water module as well. These units are small, quiet, and can be integrated with your HVAC system to create a single, streamlined system. Let us help you find a professional near you.
