Zoning: VMB is compatible with most properly sized and installed zone control systems.

The above ducted air handler fan coil units use variable speed DC inverter motor fans, as such they are highly efficient, very quiet, and long lasting. The ducted AHU fan coil units above are meant to be specified and installed only by a professional HVAC contractor. Use the chart below to see which Firstco VMB unit will handle the required capacity.

NOTE: When sizing air handlers for use with Chiltrix air-to-water heat pumps it is important to consider the capacity in BTU, air flow, and static pressure - this should be handled by your professional contractor while noting the non-standard operating characteristics of the Chiltrix ultra-high high efficiency air to water heat pump. For example, air handlers are generally rated for cooling at 44F entering water temperature. That's also fine for Chiltrix, however, if you equip your Chiltrix with DHC (Dynamic Humidity Control) it is advisable to use the extended data below to properly size the air handler for the non-standard DHC temperature (generally, 54F EWT for DHC operation). See VMB cooling and heating capacity data below. Also, attention must be paid to heating supply temperatures, recommended VMB sizing for heating use with the Chiltrix ATWHP is below.

Important Note About Ducted Air Handlers

We are happy to help you select the proper Firstco model based on BTU capacity for ducted or concealed hydronic air handler to be used with the Chiltrix air to water heat pump, however, any questions or issues regarding required air flow (CFM), static pressure, duct design, filter or other options, etc. must be addressed by your professional installer and are not supported by us. Please confirm application, fitment, CFM, needed options, etc. with your HVAC installation professional.

Many Other Fan Coil Options

If you don't prefer a ducted system, consider our ultra-high efficiency DC Inverter ductless room fan coil units for better efficiency and individual room zoning. Note, you can also mix and match - for example, you may decide to use a ducted or concealed ceiling fan coil in an  open area of your home such as a combined living room-dining room-kitchen, or a great room, etc. and then also use ductless room fan coil units for bedrooms, office, den, or other individual rooms. In addition, either ducted or ductless,or a combination of these, can be used along with radiant heating, domestic hot water, etc. with the Chiltrix air to water heat pump.

The Chiltrix system is highly flexible and can be configured in many ways. The Chiltrix air to water heat pump manufacturers support team is always ready and willing to help you create the perfect design for your home.
