THERMO 2000 VenTum 60 Hydronic Fan Coil

Up to 2,000 CFM of water-heated air, with optional cooling

In a large house that already has ductwork, switching to hot-water heating does not mean giving up forced air. The Thermo 2000 VenTum 60 hydronic fan coil takes hot water from an electric boiler or an air-to-water heat pump and turns it into warm air, up to 2,000 CFM. It is the large size in the VenTum series: 3/4 HP ECM fan, 10 x 10 in wheel, 4-row copper coil measuring 15 x 22 x 3.5 in and built-in 3-speed circulator.

The large size in the VenTum series

The VenTum 60 is meant for good-sized houses, multi-storey homes in Laval or on the North Shore, and offices or small shops that already have ductwork. Its front digital controller manages 2 zones, displays status, temperatures and alarm codes, and allows a separate airflow for each mode: heating, cooling, ventilation, dehumidification. Airflow is set in 10 CFM steps, and a BOOST mode is available. An anti-freeze function takes over if the house thermostat fails.

In summer, an air conditioner or heat pump coil can be added as an option, with an outdoor unit. Thermo 2000 associates 3 tons of cooling with 1,200 CFM, 4 tons with 1,400 and 1,600 CFM, and 5 tons with 1,800 and 2,000 CFM.

Choosing the right operating point

The heat delivered depends on the water temperature and its flow. The manufacturer publishes its capacities with return air at 70 °F (21 °C). With 120 °F water, the VenTum 60 delivers 35,900 to 47,400 BTU/h at 3 GPM, and 40,000 to 56,000 BTU/h at 5 GPM, between 1,200 and 2,000 CFM. With 140 °F water at 5 GPM, the range rises to 59,100 to 87,500 BTU/h. The published pressure drop is 5 psi at 5 GPM. We therefore start from your source’s actual temperature to choose the water flow and the airflow, then check that the ductwork stays within the maximum external static pressure of 0.75 in. w.c.

The loop can hold water or a propylene glycol mix up to 50%, with water from 50 to 200 °F. The water connections are 3/4 in copper, soldered.

Installation and next steps

AirGreen installs the VenTum in Montreal, Longueuil, on the South Shore and throughout Greater Montreal, with electric boilers and air-to-water heat pumps. Our work includes:

• the free on-site estimate and a written quote;
• setting the unit, vertical or horizontal depending on the space, with the pre-cut return on the side that works;
• connecting it to the water loop and the ductwork, and placing the supplied air temperature sensors;
• setting the airflow for each mode and commissioning.

The unit weighs 120 lb and runs on 120 V single phase. The thermostat is not included. Sold alone, the VenTum 60 does not qualify for the LogisVert grant. AirGreen is a family business established in Montreal for more than 15 years, holding RBQ licence 5645-9605-01 (ventilation, refrigeration and electrical). Thermo 2000 warrants all VenTum parts and components for 2 years, under its terms.
