Thermo-Dynamics TDE Electric Boiler
he Thermo-Dynamics TDE Electric Boiler
T
is compact, clean, quite, and does not require
a storage facility or chimney allowing convenient
installation near the point of use. The TDE electric
boiler provides an energy efficient supply of warm
and comfortable heat, and is built to ThermoDynamics quality standards – the highest in the
heating industry.
This electric boiler is versatile and provides an
easy-to-use heat source for forced hot water
systems in:
• new homes
• replacement systems in existing homes
• back-up units for solar heating systems
• supplemental heating systems for the heat
pump.
CLEAN.
The TDE heating system eliminates the need for
fuel storage facilities and chimneys. There are
never any odors to permeate the home or combustion emissions to pollute our environment.
COMPACT.
The TDE electric boiler is extremely compact and
can be easily wall-mounted almost anywhere in the
home to provide heat for areas that are isolated
from the main heat supply. These areas include
garages, apartments, and utility rooms to name a
few.
QUIET.
Quiet operation is maintained because elements are
energized in steps, thus preventing power surge and
start-up vibration. Quality electrical componentry,
circulator and cabinet design also contribute to the
whisper-quiet operation of the TDE electric boiler.
A Word About Supplemental
Heat for the Heat Pump
f you live in the great northeast, or in a region
I
of the country where temperatures regularly
fall below 40°F in the winter, the heat pump will
run almost constantly to heat the home. When
the temperatures fall below 32°F, most heat
pumps literally shut down and the resistance heat
comes on to provide back-up.
To extend the life of the very expensive heat
pump unit, the electric boiler provides supplemental heat allowing the heat pump to “rest.”
When heat is called for when the temperature
drops below 32°F, the air in the heat pump system is below body temperature and therefore
feels cool. The electric boiler can provide a heat
source that is warm and comfortable to the touch.
ENERGY EFFICIENT.
With Thermo-Dynamic’s unique “flow control”
system, the TDE electric boiler delivers a steady
flow of healthful heat using a minimal amount of
electricity. Low watt density heating elements, low
voltage thermostat and thorough insulation for
minimum heat loss are just a few design features
built in to deliver more comfort for every energy
dollar.
SMALL BOILER.
BIG IDEAS.
When your projects call for the efficiency of hot
water heat and the convenience of electricity,
choose the TDE electric boiler. The TDE is small
enough to install almost anywhere (remember, all
you need is a wall), yet powerful to handle big hot
water heating jobs.
Designed for
Reliable Home
Heating Comfort
A Summary of Practical Applications
• Solar Heating Systems. Every active solar heating
system needs a reliable back-up heating unit that can
perform through long periods of adverse weather.
The TDE is UL listed as a central heating boiler, thus
providing the power needed for total solar security.
A Summary of Product Features
• Recreational Pools. Because the TDE heats water
fast and efficiently, it is an ideal way to warm
swimming pool water. Ideal for home, hotel, club
and spa pools, and popular with the hot tubs, too. Its
powerful circulator maintains steady flow to keep
water at uniform temperature.
• Therapeutic Pools. Sports and institutional
facilities need a precisely regulated hot water supply
for their hydrotherapy facilities. Of course, the TDE
is the safe choice, offering a high limit switch feature
that instantly de-energizes heating elements at a set
temperature while the circulator continues operation.
• Condominiums, Co-ops, Apartments. When each
living unit needs individual hot water heat, the TDE is
the cost-efficient answer. It features staged start-up
for quiet operation; can be easily piped into existing
hydronic systems; is great for new construction; and a
necessity for conversion projects.

A Summary of Product Benefits
he Thermo-Dynamic TDE electric boiler features low watt density heating elements installed through the
T
sides of the boiler with ample access for service. The elements are energized in steps to prevent power
surge, prolonging heater element life and assuring quiet operation.
Standard controls are factory-wired on the control panel. All controls are easily accessible through the
removable cover.
Every TDE boiler is insulated with fiberglass insulation for minimum heat loss and housed in a rugged steel
cabinet finished in azure blue powder coat for extra durability.
Clean, compact, quiet, energy efficient, versatile, affordable, and backed by Thermo-Dynamics.
nergy efficiency is an important consideration when buying any heating system. But there are other factors you must consider too. Like manufacturer experience, reputation and service. The simple fact is, any
E
heating system is only as good as the company behind it.
Only the finest materials and craftsmanship is used to manufacture our products.
Operation
On call for heat the circulator comes on immediately, and the elements are energized in steps — two elements
per step spaced at approximately 60 second intervals. When the thermostat is satisfied, all elements and circulator are de-energized at once. A high limit condition will instantly de-energize all elements and the circulator
will continue to run.

INSTALLATION
1. Carefully remove unit from shipping
carton. Remove the boiler jacket by
removing the jacket assembly screws
around the perimeter of the jacket.
(The jacket can be reinstalled after
wiring and piping. The following
accessories are included and are
loose inside boiler jacket:
• Air Vent - mount in 1/8" pipe tap
hole at boiler top.
2. The Boiler must be wall mounted
only. The air vent provided must be
at the top of the boiler. The TDE is
provided with wall mounting
flanges integrally attached to the
boiler back sheet. There are two
holes 3/8" diameter on 16 inch centers in each flange. Securely mount
the boiler to the wall with 3/16" lag
screws or 3/16" toggle bolts. Be
sure the boiler is level before completing the boiler attachment to the
wall.
3. Allow 20" clearance in front of the
unit for removal of the jacket, for
making electrical connections and
servicing. The required side and top
clearance is 12". The required bottom and rear clearance is 0".
4. The only piping connections
required are the boiler water supply
and return, expansion tank, water
supply and drain line from the relief
valve. The circulator is factory
mounted. Flow should be UP,
toward the boiler vessel. An arrow
cast into the body of the circulator
indicates water flow direction.
5. An Expansion Tank (Not Provided)
must be matched to the system and
installed in accordance with the
manufacturer’s recommendations.
A conventional expansion type of
tank may be connected to the 1/2"
NPT fitting in the boiler top. If a
pressure type tank is used the 1/2"
opening must be plugged. See the
manufacturer’s instructions for sizing the expansion tank.
Do not under-size the expansion tank.
6. The home inlet water system shall
not exceed 60 psi. A pressure
reducer will be required if the system exceeds this pressure. An automatic feed valve (Not Provided)
should be installed in the water
inlet line to keep the entire system
(boiler and radiation) from falling
below the pressure setting of the
valve (12 psi).
7. The water supply and return lines
of the system must be connected
with shut off valves and purging
valves. Purging the system of air
prior to operation is critical to satisfactory operation. All connections
must be air tight and leak proof.
8. Required electrical power input is
three wire, 120/240 volt, single
phase, 60 hz. (The TDE-15 and TDE30 units may be wired using three
phase power, two or three branch
circuits. See wiring diagram.)
Caution
Wire the circuits as shown on the
diagram. The separate 120 volt circuit
for the circulator and control power
circuits is required to allow operation of
the circulator during the start-up
procedure, without energizing the
heater elements.
