Product Overview

Dyna-Glo wall heaters are the ideal choice for safe, indoor supplemental heating. This state-of-the-art vent free technology does not require a flue or chimney. These heaters are great for use in your home, cabin or garage. Since these heaters do not require electricity to operate, they make an excellent choice for everyday heating and emergency situations when the power goes out. Using blue flame heating technology, heat is distributed similar to your central home heating system. This Blue Flame Wall Heater burns with 99.9% efficiency and operates on Natural Gas only. Not for sale in California or Canada. Check your local regulations on installation restrictions and requirements. DEPENDABLE: Ideal for daily supplemental or emergency use, such as power outages. ECONOMICAL: Cut heating bills by warming only occupied areas. COMFORT Manually adjust the heat setting to your desired temperature. SAFE: Built-in oxygen depletion sensor (ODS) immediately shuts down the heater if carbon monoxide or lack of oxygen is detected. CONVENIENT 1 continuous press of the battery assisted igniter makes ignition quick and effortless. VERSATILE: Includes all necessary hardware and bracket for wall mounting. UPGRADEABLE: Separately sold optional base legs (WBL100) provide the alternative of floor mounting. Separately sold optional Wall Heater Fan (WHF100) distributes heat in a quiet, yet powerful way.

Works well, maybe too well as settings have little differential between low and high. I would have bought the 20k BTU rather than the 30K had I known this,

Nice fan, good value
Replaced an old heater and this one works just fine. Lights easily, unlike my old one. Heats my basement immediately. No complaints with this one.
