Most people would have at least asked this question once in their lives even before thinking of buying the
latest power vent water heaters: Should I use Electric Heaters
or Gas Heaters for home? In another words which is better to choose for their home, electric heating or gas
heating? Well actually there is no one right answer and it depends on a lot of things which this article we found
attempts to put to rest this popular question.
Electric heaters are cheaper, easier to install and
do not need a chimney like gas heaters do. However, gas heating has lower operational costs because gas is usually
cheaper than electricity and gas heaters are better at warming up larger spaces. Electric heaters may be more
economical when used is small rooms.
HVAC and Home Heating
Types of electric heaters
There are two kinds of electric heaters:
Radiation heaters - A heating element that reaches high temperatures is packaged inside a glass envelope
that emits heat as infrared radiations. A reflector directs the heat away from the heater. The radiation
travels through air until it reaches a heat absorbing body. They provide spot heating. Examples of these types
of heater is infrared heaters.
Convection heaters – Heating element heats the air next to it by convection. Hot air rises up and cold air
rushes in to fill the gap and is heated. Thus a constant hot air current flow is setup. This is best suited for
closed space. Examples of these types of heaters are ceramic and oil filled heaters.
Types of gas heaters
Gas heating is of two types:
Flued heaters – These are permanently installed. The flue should be installed at correct height to extract
all the emitted gas.
Non-flued heaters – These are vent-free or flueless heaters. They can be used in a room with proper
ventilation. But the ventilation might cool the room.
A gas heater or furnace needs a chimney to send out the emissions due to the burning of gases. Installation
generally requires air ducts and vents throughout the house. The heater itself is quite large and needs
Portable electric heaters do not need installation. Wall-mounted electric heaters do need to be installed but
the installation is much easier than gas heaters and can be done yourself.
The cost of installation of gas heaters is more as they need a centralized furnace with flue outlets to be
installed. Electric heaters are comparatively cheaper.
edit Operating Cost
Gas heaters produce more heat when compared to electric heaters in the same amount of time. Since gas is
generally cheaper than electricity, a gas heater has lower operating cost. Electric space heaters are cheaper
only when a small space is to be heated at lower temperature settings.
Gas vs. Electric Water Heaters
When it comes to water heaters, some of the same considerations apply. Gas water heaters are not 100% efficient
and need to vent out gas via a chimney. There are some high-efficiency gas water heaters that do not require a
chimney but use a fan and pipe to vent out via the side of the house. Electric water heaters do not have any
such venting requirements.
Storage water heaters use a tank to store the hot water. These are different from point-of-use water heaters,
which are smaller and installed in bathrooms where the hot water is needed. POU heaters are almost always
electric while heaters with water storage tanks can be both gas and electric. Gas heaters are much more popular
than electric water heaters in the United States and most European countries because gas is often conveniently
piped throughout cities and towns and currently is the cheaper to use than electricity.
Gas heating is more suitable for larger households because the heating is faster than electric heaters. For
households with only a couple of members, the storage tank capacity is usually enough to not require quick
re-heating. So electric heaters can work for them. Electric heating may be the only available option if a
chimney or another outlet is not available for venting.
"Electric Heating vs Gas Heating comparison. Electric heaters are cheaper, easier to install and
It is important to note that while the costs of running gas heaters for home differ from electric heaters
for home, many people are prepared to pay more to satisfy their own specific needs and requirements. Afterall,
keeping their family safe, warm and happy especially on harsh winter days cannot be more important.
