Careful planing and a lot of future thought went into the developement and design of this complete heating system.
With future plans of a major expansion down the road, this system was designed to provide all the heating requirements
that will be needed. Provisions for radiant heating, second stage back up hydro air coils, garage space heaters, future pool heating
and snow melt systems were all incorporated into the build of this boiler room. Literally, this is a "Plug and Play" system that will
enable this house to morph into its final configuration.
 
The choice of dual Mod-Con bolers was elected for two reasons:
 
#1 - To provide the most efficient means of supplying heat upon demand. One boiler will handle the majority of low-demand
requirements, which is most of the time. Upon high demand requirements, the second boiler will kick in and provide the extra btu's
to get the job done. The Tekmar Universal Reset module rotates the running time of both boilers to share the work load and wear and tear.
 
#2- Having two boilers provides redundancy in the case of a boiler failure. If one boiler drops off line due to boiler failure, the other
will kick in to keep things going. A Generac natural gas generator was also installed to provide redundancy for whole house electrical power back up.
Home automation was tied in using the Tekmar 482 Gateway control to provide iPhone monitoring and system control. The system is fully operational
and ready to go. All that has to be done is run the final piping and wiring down to the boiler room and literally "Plug and Play".
 
This is the way all installations should be designed and built.
 
And yes, those are remote controlled RGB LED lights around the system boards and behind the Tekmar controls.
