Raypak’s Next Generation Condensing
Heater
Time-honored technologies unite with cutting-edge advancements in
Raypak’s new XTherm vertical heater. Never before has a vertical
heater provided both the installer and pool builder such installation
flexibility, ease-of-commissioning, reliability and long-term
performance. Small space, not a problem. The XTherm has one of the
smallest installed footprints of any vertical condensing heater. Our
compact design makes it the perfect choice for those hard to reach
retrofit projects. Raypak’s XTherm is built with commercial-grade
components and materials. From our steel channel base to our
stainless steel flue wrapper, and secondary heat exchanger, you can tell
the XTherm is built to last. It’s easy to handle and install, but still user
friendly to service. Now is the perfect time to take a closer look at
Raypak.
Flexibility
Industry-leading vent length allowances afford greater vent location
options, thus reducing wasted space. Vent versatility is further
enhanced by the self-tuning combustion system which compensates
for unusual chimney and vent configurations.
Category IV - CSA-certified 97%
efficiency at full fire for water heaters in
pool applications. When the job requires
high efficiency, XTherm meets your needs.
The XTherm can use either AL29-4C
stainless steel, PVC or CPVC for venting.
Just specify the D-32 vent option when
using PVC vent.
At the heart of every Raypak XTherm is a unique integral evaporator
system - the first defense against condensation in the primary heat
exchanger. Raypak’s evaporator system collects and re-evaporates
condensate which may form during initial start-up.
Simplicity
The Raypak XTherm will precisely heat your pool. Utilizing the latest
European technology for the combustion-components, the optimum
fuel-air ratio is maintained throughout the entire range of the load-
tracking operation. The XTherm automatically self-tunes to
accommodate the widest range of gas supply pressures. The high
quality integrated blower-gas valve is self-correcting and allows
smooth operation with fluctuating gas supply pressures. The Raypak
XTherm is cutting edge technology with atmospheric simplicity.

Xtreme Pumping
Co d Water Run System
The XTherm comes standard with a state-of-
the-art Cold Water Run system factory mounted
and plumbed. Raypak’s Cold Water Run system
provides constant protection against
condensation in the primary heat exchanger.
The system utilizes a variable speed pump to
inject just the right amount of water from the
main system loop into the heater to maintain
the optimum inlet temperature. This allows the
full capacity of the heater to be utilized to meet
the system load, while at the same time
continuously maintaining the optimum inlet
water temperature to prevent condensation in
the primary heat exchanger. All of this keeps the
condensate were it belongs, in the stainless
steel secondary heat exchanger.

Efficiencies
Xtreme Pumping
The annual fuel usage is based on maintaining an indoor
swimming pool at 80ºF for 6 months of the year and using a
fuel cost of $1.00 per therm.
How to use the table below:
1. Select the desired temperature of the pool water.
2. Determine the mean (average) temperature of the month in which the pool will be
used.
3. Subtract the mean temperature from the desired swimming temperature. The
difference is the temperature rise.
4. Calculate the surface area of the pool in square feet.
5. Under the column headed by the temperature rise, determined in Step 3, find the
number closest to, but not less than, the pool surface area from Step 4. The left-hand
column will give you the correct model heater.
Sizing Formula
BTUH INPUT REQUIRED = (Pool Surface Area square feet) X (Temperature Rise) X (15)
This formula is based upon a 1º to 1-1/4º F temperature rise per hour and an average
3-1/2 MPH wind velocity.
Where high-wind conditions exist, select one size larger than determined by the
formula.
Rapid Heating
For 1-1/2ºF rise per hour: Increase BTUH input by 50%.
For 2ºF rise per hour: Increase BTUH input by 100%.
Always select a heater equal to or larger than the requirement. Over-sizing generally
reduces fuel costs.
