All Ecologix air systems come supplied
with spring loaded, vertical lift check
valves. These check-valves have been
tested and proven to resist thermal
siphoning for installations where the air
handler elevation does not exceed the
distance above the water heater shown
in the table below.

Connecting to a Water Heater
Any properly sized gas, propane or oil
fired water heater will work in a combo
heating system. Make sure the water
heater being used is approved for combo
applications. (Most manufacturers’
heaters are approved.) Tank-less water
heaters may reduce the capacity of air
handlers due to the higher internal
pressure drop. (Call Ecologix for details)
Connecting to a Boiler
All Ecologix air systems are compatible
for use with boilers. Standard drawings
are available from Ecologix for most
boiler applications.
EQUIPMENT SELECTION AND SIZING
Proper sizing of system components is
crucial for proper operation.
Steps for sizing and selection:
1) Obtain room by room heat loss and/or
heat gain
2) Determine heating water temperature
3) Select air handler from specification
sheet
5) Determine duct layout
Heat Loss
Make sure a proper room-by-room heat
loss and heat gain for the dwelling is
calculated using HRAI, ASHRAE or other
approved sizing method.
Air Handler Selection
Select the desired air system that will
meet 100%-140% of the heating load
and 80%-120% of the cooling load.
If using a boiler system, select a boiler
that has an output that meets or exceeds
the heat loss of the space being heated.
If the boiler is meeting additional loads,
size the boiler to meet the total combined
load.
For combo heating systems, use an
approved sizing method such as the
Unified Combo Guidelines published by
HRAI. In areas where the UCG or a local
sizing code is not applicable, use the
following method for sizing combo
systems:
1) Select an air handler that meets or
exceeds the calculated heat loss at the
water heater operating temperature
(130F/55C or 140F/60C).
