Intrepid can provide hot water all year
long for your kitchen, bath and laundry.
Optional high output tankless heater. This coil type “instant” hot water
maker is located inside the boiler where the constant flow of hot boiler water heats
your fresh water as it passes through the coil. Intrepid’s extended coil well accom-
modates a larger coil to maximize output. Recovery is fast and the total capacity
will vary with the boiler size.
Indirect water heaters. If you
prefer to have a larger reserve of hot
water, your installer can provide a hot
water storage tank that is easily
connected to the Intrepid boiler. These tanks typically store
between 20 and 60 gallons of hot water. Some require the
boiler’s tankless heater coil to make hot water. Others have built-
in heating coils which are connected to your boiler in the same
fashion as a heating zone. Your heating contractor can recom-
mend which domestic hot water system is best for your needs.
Zone your heating system for even
greater fuel savings.
By dividing your home into separate heating
zones, you can save energy by heating only
those areas you’re using. Depending on your
existing piping arrangement, it may be quite
simple to zone your system. An auxiliary return
tapping on the Intrepid boiler gives the heating
installer added flexibility in setting up two or
more heating zones in your home.
