Patio radiant heaters are used to heat the patio of your home
without heating the surrounding air. The heat generated from these heaters is
as warm as the heat generated from natural sunshine (minus the ultraviolet
rays). Patio radiant heaters are a good alternate to gas and propane patio
heaters, just plug them in and enjoy the warmth. Radiant heaters can be mounted
on to the walls, ceilings or under the awnings.
Patio radiant heaters are amongst the most efficient types of heaters that can be used on the patio. They are
effective because radiant patio heaters heat up the surrounding objects and not
the air in between. These modern patio radiant heaters use the technology of shortwave
heating (they use electromagnetic infrared radiation); this supplies radiant
heat energy that warms the people and the solid objects within the beam of the heat.
This technology in the heater prevents the heater from heating the air (air can
be blown away easily and thus the heat might not be very effective). This
method of heating is one of the oldest forms of heating.
Once the heater is turned on, heat is generated at the maximum power thus making it very effectual. These
heaters supply instant heat and require no time to warm up. Objects and people
feel the heat without coming in direct contact with the heating system. Glowing
quartz or metal elements and reflectors are used to provide heat to a
particular spot.
Patio radiant heaters are safe to use, easy to operate and emit no odor. Patio radiant heaters require very minimal
maintenance and are very cost-effective. Patio radiant heaters are the best
choice for any outdoor event like a backyard wedding, a chilly evening barbecue
or outdoor family dinner. Patio radiant heaters add about 10 degrees of warmth
to an outdoor patio. Patio radiant heaters are available in differing wattages
and lengths; choose the one that suits your requirements (depending on the area
to be heated up). A unit costs $200 upwards.
Benefits of patio radiant heaters
- The heat generated is continuous.
- Bad weather conditions do not affect/interrupt the flow of warm air.
- They are easy to use.
- These heaters require very little overhead clearance.
- They can save lot of space as they can be wall or
ceiling mounted.
- These heaters use non combustible fuel to generate
heat.
- These heaters save a lot of energy as they warm
things and people instead of warming the surrounding air.
- Heating temperature can be set as per the area that
needs to be heated up.
- No smell of gas while the heater is on.
- Can be self installed whereas gas heaters have to be
installed only by specialists.
Outdoor patio heater
Patio heaters provide radiant heat and remove the chillness from the air outdoors. These heaters gained popularity
after restaurants and pubs banned smoking indoors. Patio heaters are gaining
popularity with homeowners too. Patio heaters are also popular as umbrella or
mushroom heaters.
A burner is fixed on top of a post and it burns either LPG or propane. The flames are directed towards a perforated
metal sheet. This sheet radiates heat in a circular pattern and the reflector
fixed on top of the burner reflects heat. In simple words heat is radiated from
the inner chamber through a metal mesh. Apart from these conventional patio
heaters, infra-red patio heaters are the latest type of patio heaters that
utilize grid electricity for heating purpose. Heat for patio heaters is
generated either through electric coils or through gas.
Patio heaters can alter the temperature within a radius of about fifteen to twenty feet. The surrounding
air can be warmed up to 25 degrees from the existing temperature. Turn/dial
switches are used to control the temperature. Patio heaters are made from steel.
Piezo electric ignition is used as ignition in most of the models, automatic or
electronic ignition is used in high-end heaters. Patio heaters are available in
various sizes from 20,000 BTU/hour to 50,000 BTU/hour.
Majority of outdoor patio heaters are made of durable materials like stainless steel. Decorative patio heaters
with antique copper finish or heaters painted in different colors are also
available.
Patio heater styles
Tabletop patio heater: Tabletop patio heaters use small disposable
propane gas cylinders. These models of heaters are not very expensive. Table
patio propane heaters use a dome to radiate heat in all directions. They can
warm an area of about 8 feet to 10 feet in diameter and are efficient in
heating small areas.
Free-standing patio heaters: These patio heaters stand up from 70"
to 93" and can be positioned anywhere on the patio. These heaters have
wheels on their pedestal and can be moved anywhere easily. Most heaters are
designed to burn propane. Heat up to 40,000 BTU's can be attained and the heat
can be radiated between 15 and 25 feet radius. Generally propane cylinders are
used to fuel these heaters.
A gas line runs through the burner assembly of the heater. A hose and regulator are also connected to the
gas line. The regulator in turn is connected to the propane cylinder. The gas
line also has a flare fitting which is connected to the post. The flare fitting
is connected to the hose and regulator assembly on the gas line. The regulator
is attached to the propane cylinder. The burner assembly is fixed to a post; a dome emitter is fit on the top part of
the lamp. The propane cylinder is at the base of the lamp. You can use a switch
to regulate the temperature of the lamp. The propane passes from the tank
through the gas line up to the hose, regulator, and burner and to the top of
the post (where the dome emitter is placed). The propane burns thus producing
heat which is emitted through the emitter.
Other expensive models use a natural gas line, electric free-standing patio heaters are also available but
they can provide heat up to 11,000 BTU's only and can reach a radius of about
10-15 feet.
Hanging patio heater: People having space crunch can choose hanging
outdoor patio heaters. Outdoor hanging patio heaters can radiate more heat than
a free-standing heater. Hanging outdoor patio heaters are very versatile as
they can be moved with ease. These heaters are hung either from the ceiling or from
the eaves by a steel frame thus saving floor space. Hanging patio heaters have accurately
designed reflectors that reflect and preserve heat just like portable patio
heaters. Natural gas or propane is the most commonly used fuel in such heaters,
electric heaters are also available.
Electrical hanging patio heaters are economical to use and heat up a large area within seconds. Heat can be
adjusted using the heat regulator switch. Heat up to 50,000 BTU can be achieved
using this heater. An electric piezo spark ignition system is used to spark the
ignition.
Types of Patio heaters
Patio propane heaters: Most models of patio heaters burn propane, also
known as LP gas, from refillable tanks (similar to the ones used by gas grills).
LP gas can be supplied from 1 or 2 pound LP cylinders or they can be connected
to a larger LP cylinder using a hose. Some propane patio heaters are portable and
can be used for trekking or camping. Tabletop patio heaters use small
disposable propane gas cylinders. These models of heaters are cheaper than
natural gas heaters. Table patio propane heaters use a dome to radiate heat in
all directions and are efficient in heating small areas. Such heaters require
adequate ventilation while being used. They are available in three basic types
namely free-standing, portable and fixed.
Benefits of patio propane heater
- They are portable
- They are cost-effective
- Large units can emit up to 40,000 BTU
Limitations of patio propane heater
- High maintenance cost as tanks need to be refilled
Patio natural gas heaters: Natural gas lines can be connected to
patio heaters instead of propane cylinders. The standing gas patio heater using
natural gas is highly effective in producing additional heat when compared to
the gas-fueled table model or electric model heater. It can heat a large area
when compared to other heaters. The heaters are 6 or 7 feet tall and have a
mushroom-like dome on the top. This dome directs the heat downward in a
360-degree radius. They are available in three basic types namely free-standing,
portable and fixed. The heaters fueled by natural gas produce no odor and are
combustion free too. Additional features include push button igniters,
adjustable heat control, automatic re-light and remote control switches.
Benefits of patio natural gas heater
- Efficient and clean-burning
- Can
increase temperatures by 10 to 25 degrees F
- Creates
a 15 to 20 foot circle of warmth
Limitations of patio natural gas heater
- They
are not portable as they are directly hooked onto the gas line
- They
require professional installation
Patio electric radiant heaters: Electric patio heaters are
efficient and produce heat very quickly. These heaters do not emit fumes or
pollutants. They utilize infrared beam to heat up the area. Wall-mounted,
ceiling-mounted and few free-standing styles of heaters are available. These
heaters are either corded or hard-wired. Patio electric heaters are the easiest
type of heater to use and can be plugged to the existing electrical source
itself. External weather conditions like chill wind and breeze do not affect
the heat output. These heaters are both cost effective as well as energy
efficient.
Benefits of patio electric radiant heaters
- They
are available in both portable and permanent models
- Practically
nil warm-up time
- They
are economical
Limitations of patio electric radiant heaters
- Need
access to an electrical outlet
Safety Features in patio heaters
- Automatic shut-off to check overheating
- Safety tilt shut-off switches to avoid heaters from lighting objects on fire if they tilt over accidentally.
- Heat adjustment
- Pilot lights
- Tip-resistant construction
- Shut-off switches to safeguard against severe weather
