John Wood® Commercial
Tankless Water Heaters
John Wood powered by Takagi commercial models offer important factors for any commercial
organization or business: saving space, energy and money. Offering light duty models for lessdemanding commercial applications to robust models to suit the most challenging of applications.
Features
• Tankless water heaters only activate
when hot water is being used - therefore
no standby energy losses are incurred,
providing efficient heating and conserving
gas energy
• Condensation-reducing design to prevent
premature failure of the heat exchanger
from excess condensate
• Models feature multiple unit installation of
up to 4 units with no additional accessories
and up to 20 units with TM-MC02 system
controller (except JWT-510)
• Heat exchanger manufactured with HRS35 commercial-grade heat-resistant copper alloy that
has 8 times more tensile strength than regular copper ensuring its longevity and 25 times the
heat transfer rate than stainless steel
• Drums that are 25% thicker, ensuring the longevity of the water heater - a thicker drum creates
less strain on the heat exchanger
• Can be installed as a Direct Vent with the
purchase of a Direct Vent Conversion Kit (with

Atmospheric Vent Water Heaters
The next generation of Atmospheric Vent natural gas and propane water heaters handles a
wide range of applications with inputs from 120,000 BTU to 500,000 BTU. With Intermittent
Electronic Ignition, these units save energy by eliminating the standing pilot and the high
pressure water jets reduce sediment at the bottom of the tank prolonging tank life.
Features
• Meets or exceeds ASHRAE 90.1 energy efficiency standard,
80% thermal efficiency
• Self cleaning water jets
- Reduces the build up of sediment at the bottom of the tank
prolonging tank life
• Inlet and outlet ports at the top, front and back
• Factory-installed T&P and brass drain valve
• Conveniently located hand hole cleanout
• Low-profile vent damper for energy efficiency and installation
in tight spaces
• Intermittent Electronic Ignition
- Eliminates standing pilot, saves energy, and provides flame
failure response very quickly
• Glass-lined tank with multiple anodes
- Provides protection against corrosion extending tank life
• Maximum hydrostatic working pressure 160 psi
• ASME and high-altitude models available
Optional Accessories Available
• Power Vent kits
3 year inner tank warranty, 1 year on parts.

Storage Tanks
Our line of professional hot water recirculating storage tanks are available in 80 and 119 US
gallon models, jacketed and insulated or bare and enamel painted. Manufactured with ease
of installation in mind, connections are simplified for large recirculating water lines, while
the tanks come complete with easily accessible openings for a one inch T&P valve and a 3/4
inch aquastat.
2” NPT
(2½” FOR JWCE-119)
3/4” NPT
(ANODE)
Features
• Glass-lined tank to protect against
corrosion
• Threaded openings - for
thermometer, relief valve,
recirculation lines, aquastat
and drain valve
• Magnesium anode(s)
• 150 psi working pressure
• Insulated models use high
density fiberglass insulation
to reduce costly heat loss;
non-sagging and vermin-proof
