This Pellergy boiler makes hot air just like a wood pellet furnace. The boiler sends hot water to a plenum where it heats up a coil. A blower then passes air over the coil. This air is then distributed throughout the home via a duct system. The rooms heat up very evenly because the air is heated to around 120ºF to 140ºF. The air is also not dried out as much as a regular forced hot air system due to the regulated coil temperatures. .
On an interesting note, the hydro/air coil also has an A/C evaporator coil and controller built in so the unit can also be used to provide air conditioning with the installation of an outdoor compressor unit.
Additionally, the system can be used to generate domestic hot water with an indirect water heater and can also be expanded to add hydronic heating zones within the house. This includes not only radiant floors but also hydronic baseboard, radiant panels, and fan convectors. These options are ideal for keeping bathrooms cozy and for heating kitchens where there may not be much available wall space.
The hydro/air system can also accommodate air filtration for removing pollutants and allergens in your home’s air, as well as humidity control. Keeping your home’s humidity between 30-60% can help reduce the effects of many unwanted conditions in people and buildings.
Hot water can also be sent to remote rooms like the garage where duct work may not be present. A Modine is the perfect way to heat up a remote room quickly on demand.
A wood pellet boiler with a hydro/air system… Very versatile and all for less than the cost of a wood pellet furnace.
