Overview
Mounting the Rinnai EX22 on a wall turns it into a direct vent propane heater for one room or zone, warming the space by convection. A modulating gas valve and variable speed inducer motor adjust output to the room's needs, guided by an electronic programmable thermostat.
Modulating heat and quiet operation suit living spaces where a cycling heater would be noticed. Installation is the limitation: it is a heavy gas appliance needing a vent and a propane supply, and the listing gives no venting kit details. A few listed numbers conflict, so check the spec sheet.
Who it's for
Cabins, additions and rooms the central system misses, where propane is already on site, suit this furnace. Renters and households without a propane line or a professional installer should look at a different heater.
Pros and cons
- Modulating valve matches heat to the room
- Programmable electronic thermostat
- Electronic spark ignition
- Virtually silent operation per the listing
- Listed heat output and voltage figures conflict
- Vent kit contents not listed
- Heavy unit needs secure wall mounting
- Propane model only
Performance notes
Room comfort is governed by the modulating gas valve, which steps output up and down to match demand, paired with a variable speed inducer motor. Convection moves warm air through the room, so layout and closed doors affect how far heat reaches. The electronic thermostat decides when output changes, and the programmable schedule lowers heat when nobody is home.

The title states 20,700 BTU while the spec field reads 700, which looks truncated. Confirm the rating on Rinnai's spec sheet.
Can I schedule temperatures on the Rinnai EX22 wall furnace?
Yes. The listing describes a programmable thermostat for customized settings, such as less heat while you are away.
What electrical supply does the Rinnai EX22DTWP need?
The listing gives the voltage as 60 volts, an unusual figure for a household appliance. Confirm the supply requirement with Rinnai or your installer.
Is the Rinnai EX22 safe around children?
The listing describes a cool-to-the-touch cabinet, a child lock and self-diagnostic electronics. It is still a gas appliance that needs professional installation.
