Patented Econotherm Heat Exchanger

Your VERSA is equipped with a unique all-copper-fin-tube heat
exchanger, designed for efficient heat transfer and built to provide
years of trouble-free performance. Both header castings are made
of porcelainized cast iron for durability and resistance to corrosion
and rust. Your VERSA is also available with optional premium
bronze headers for completely rust-free operation.

Advanced Unitherm Plus Full-Flow System

Condensation-free operation is ensured even with low temperature
inlet water. Both water temperature and flow rate inside the heater
are controlled to eliminate condensation, sooting and scale build-up
that can shorten heater life. More hot water moves through faster,
and more efficiently.

Heating Capacity

The table below shows the heating capacity of the VERSA 155 in
temperature rise per hour for a given amount of water. For example,
the heater will raise the temperature of a 400-gallon spa 36 °F in
one hour. (Spa size in gallons = surface area x average depth x 7.5.)
The same heater will raise the temperature of a 400-square-foot
pool 1-1/8 °F in one hour.

Two-Year Limited Warranty

The VERSA features a two-year limited warranty against defects in
materials and workmanship (see warranty for details). In addition,
every VERSA is thoroughly tested in simulated field conditions
before shipment.

Note: Outdoor stack and indoor drafthood can be supplied but must be ordered separately.
