Air to water exchangers are available in six different BTU outputs ranging from 80,000 BTU up to 200,000 BTU. These exchangers are designed and circuited for use with hot water. This application works much like the heat in an automobile. Hot water is constantly circulated through the coil which is located on your existing forced air furnace. The fan on your furnace is then used to blow air across the heated coil which is then distributed through your existing duct work. The advantage to this system versus your existing furnace is that this exchanger remains hot and via convection the hot air naturally gravitates through your duct work reducing the amount of cold air that is often felt when a standard furnaces is in operation.

FlatPlate brazed plate heat exchangers are designed and tailored specifically for hydronic applications. Available in 40,000 BTU to 360,000 BTU these exchangers are perfect for Domestic Hot Water, Radiant Floor, Spas and Swimming Pools, and Boiler Applications. The plates are stacked for maximum use of the surface area and to form two independent circuits running in alternate layers. The two fluids flow in opposite directions to further enhance the exchange of heat. Specially embossed stainless steel plates increase the heat transfer coefficient and lower potential fouling.

Next to the furnace and underground pipe the circulator pump is the next most important item in your system. Grundfos, Taco, Bell & Gossett are just a few of the brand name pumps available. No matter what brand name you choose you should consider bronze construction. Unlike a indoor boiler which is a closed system, many outdoor boilers are open systems, and are susecptable to oxygen infiltration. Oxygen, water, and cast iron due not make for a durable and dependable system. The next important item to consider when choosing a circulating pump and GPM's and head pressure. To maximize your exchanger BTU output use this basic rule of thumb 1 GPM is required for every 10,000 BTU's of output. Example a 140,000 BTU exchanger requires 14 GPM's of 160-180 degree water to to be efficient. The second important item is Head pressure, this is the amount of resistance the pump must over come. This can be caused by size of supply and return lines, length of run, and height from pump to highest point of water circulation. Many customers and installers try to save money by installing cast iron pumps, with no consideration for GPM requirements or head pressure. This will inevitably lead to premature pump failure and more importantly a system that is not efficient.

Designed for large open applications these unit heaters are great for garages, work shops, and pole barns. Five different sizes (40,000 BTU to 200,000 BTU) make it easy to find just the right unit for any application. Some units are equipped with speed adjustable motors giving you the ability to fine tune the balance between performance and efficiency. Units use 110 volt thermostat. Thermostat and speed control are sold seperately.

These units are designed for performance and flexibility. Units can be installed in a up, down or horizontal air flow position. Unit includes heat exchanger, filter, and filter rack. Available in sizes ranging from 67,517 BTU to 237,010 BTU there is a unit availabel to fit almost any requirement. Designed to be used in place of a forced air furnace these units can be equipped with air conditioning as well.

Kick space-Recessed Wall Mount-Surface Wall Mount. When there is not enough wall space to install baseboard radiation, install The Kicker from Southeastern Heatmor. The compact Kicker provides the heat output of up to 12 feet of baseboard, depending on the model you choose. Sized to fit under cabinets or between wall studs, the Kicker is simple to install and easy to operate. An aquastat inside the Kicker automatically turns on and off the fan, delivering a quiet flow of heat to the room whenever the water is hot. A convient switch allows the user to set the fan speed on high, low or off. The Kicker may also be installed with it's own thermostat.
