Wall Mounted Gas Combustion Space Heaters
Gas wall heaters are usually designed to burn either natural or LP gas, so take care
to buy the model that matches your fuel type.

Also, take a look at this
chart to find out if the installation of vent free gas heaters is
permitted in your state, city, or town.

Unvented combustion heaters use the room air for combustion. Unless you keep a
window opened slightly, an unvented heater will burn essentially the same air over
and over constantly reducing the level of oxygen in the room.

To protect yourself from oxygen depletion, unvented heaters should be equipped
with a carbon dioxide detector. These devices sound an alarm when the oxygen
level in the room drops below 18%.

A carbon dioxide detector should not be confused with a carbon monoxide detector.

Vented combustion heaters are designed to be vented directly to the outside
through a wall or the ceiling. Fueled by a continual supply of fresh air from the
outside, a vented heater burns more efficiently with fewer pollutants than an
unvented heater.

All combustion space heaters should be professionally inspected every year just like
any other furnace. If your gas wall heater is vented, venting pipes should also be
inspected. Vents that are blocked, separated or corroded can result in the
accumulation of potentially fatal levels of carbon monoxide.

Carbon dioxide can also be produced if the heater is not properly set up and
adjusted for the type of gas used and the altitude at which it is installed.

Depending on the model,
unvented combustion heaters should not be used at
altitudes greater than 3,500 feet and never more than 5,000 feet.

Vented combustion heaters will function efficiently at higher altitudes as long as the
orifice is adapted to accommodate thinner air. A yellow flame indicates a lack of
oxygen.

Wall mounted gas combustion space heaters are permanent indoor fixtures fueled by
natural gas or an outdoor propane tank. The most popular models are the vent free
units since they're inexpensive to purchase and don't require expensive venting.

In terms of the amount of heat you get for what you spend, wall mounted gas heaters
are 99% efficient and offer the best value when compared to other supplemental
heating appliances. This is especially true when you factor in recent natural gas prices.

By way of comparison, the cost of natural gas today is the same as paying $1.10 a
gallon for heating oil.

Although unvented gas heaters aren't allowed for use as a primary heating system,
many homeowners report it satisfies most of their heating needs none the less.

Battery powered electronic ignition is a welcome feature for Seniors and allows the
heater to function during power outages. The optional
blower kit however runs on
electricity and won't operate unless the power is on.
