The Dual Coil reduces equipment costs and installation time while saving space by combining multiple hydronic
system components into one unit. Figure 1 shows how boiler cycling is reduced in radiant heating applications to
increase efficiency.
Figure 1
Radiant Zone with Domestic Water Controlling Supply Temperature
By combining two high capacity heat exchangers in a single unit, the domestic water temperature can provide reliable
control of radiant supply temperatures. Double wall heat exchangers are also readily available for systems using
antifreeze solutions where required by code.
This setup simplifies installation and eliminates the need to purchase expensive heat exchangers and mixing valves.
Boiler cycling is reduced by the domestic water mass, performing the same function as a buffer tank
