Outdoor Electric Heaters are fast becoming the standard products used both in
the home and commercial environments such as pubs, clubs, bars, cafes and
restaurants, wishing to benefit from instant heat outdoors as and when it is
needed. The range of Outdoor Electric Heaters has increased significantly
over the last few years and one can now find fully waterproof electric heaters
that can be either wall mounted, parasol mounted or completely free standing.
To go with this new range of products there is also a selection of quality
controllers and switches to efficiently operate them.
Outdoor Electric Heaters make sense, not just commercial sense but also
environmental sense. Commercially, the cost of Outdoor Electric Heaters is
about 9 pence per kilowatt per hour and with the average outdoor heater using
about 2 kilowatts of power, a typical pub or club, with say two of these
heaters, will only be consuming electricity at a rate of 36 pence an hour. To
make a direct comparison, two equivalent gas outdoor heaters will be costing
something in the order of £2.50 per hour in gas alone to run, so environmental
Outdoor Electric Heaters are certainly the way to go.
Why are they so much cheaper to run?
The answer to that question is relatively simple. The infrared heat derived
from the quartz heaters is beamed rather like that of a light in a torch or
flood lamp and therefore can be directed onto the people that need the heat,
as apposed to gas patio heaters which send out heat in 360°, much of which
goes straight up into the air. The other significant difference is that 90%
of the heat from an electric heater is infrared and therefore heats the person
rather than the air in between the person and the heater, with their gas
counterparts only 20% of the heat is truly infrared, in which case, 80% of it
is simply heating the air in between the user and the heater. This is highly
inefficient, extremely wasteful and not at all environmentally sound.
Outdoor Electric Heaters also have a much better safety record than their gas
counterparts. This is largely due to the fact that the majority are mounted
high, well out of the reach of probing fingers where they can provide their
heat silently and efficiently without interference. We have had reports of
accidents with gas heaters, where they have simply been knocked over by
accident and fallen onto unsuspecting victims who have suffered severe burns
as a result. In this day and age when all businesses are having to take much
more seriously the health and safety issues, Outdoor Electric Heating is a far
safer option.
As I mentioned earlier there is a large selection of products available,
however, these can be simply grouped into a few categories. Firstly, is the
heater waterproof or weatherproof? The IP rating of each heater gives an
answer to this question. Any IP rating consists of two numbers, the second
number in the sequence relates to the water ingress of the product. Any
product where the second number is four or above is effectively waterproof and
entirely safe for full outdoor use. On our website we clearly mark each of
these products with a water droplet symbol and all products marked with a
symbol can be mounted with no protection whatsoever and operated in any
weather conditions. We have seen demonstrations of products from Burda
working quite happily inside a fish tank full of water and Tansun similarly on
their recent exhibition stand had their system set up to squirt water all over
the heater element when switched on. Star Progetti have issued us a video
showing their Helios Top products working without a glass cover outdoors with
a child spraying a hosepipe full of water all over it. Clearly all these
products are truly water and weather resistant. Customers should take care
when considering if they need a weatherproof product as even if a heater is
placed under a parasol or a substantial awning, it will inevitably still pick
up a substantial amount of moisture from the morning dew, in the same way as
most of the things we leave outdoors over night end up wet in the morning.
The next key thing to consider when buying Outdoor Electric Heater is the
amount of power needed to provide the level of outdoor heat required in any
given circumstance. As a rule of thumb, we would say a minimum of 1 kilowatt
of heat for every 5 square meters, however, there is a big caveat with that
calculation! It is important to consider the extremes of when the heater is
going to be used, if the Outdoor Electric Heater is being used only in the
spring, summer and autumn the amount of heat needed will be considerably less
than if it is also required to work in the extremes of winter. Clearly, if
one wishes to heat, say a pub smoking patio when it is -4° outside in the
middle of February, a considerable amount more heat is needed to achieve the
given comfort level. More powerful heaters will project the heat at greater
distance, therefore if you are looking to heat a long narrow area and the
heater can only be placed on the narrow wall you will need a lot more power
from that one specific heater to push the heat in that direction. The Tansun
Bermuda is an excellent example of a heater that will project its heat a great
distance away from the source and is excellent for such environments.
Inevitably, the aesthetics of a product have a major part to play in, if it's
suited to a given environment. Burda's Term 2000 range is a class act and are
considered by many to be the 'Rolls Royce' of the industry. They are made
from solid aluminum cases and look particularly modern and state of the art.
Burda are designed and manufactured in Germany, which perhaps explains why
they have gone for this stylish and classy approach. They are more expensive
kilowatt for kilowatt than their counterparts; however, this hasn't stopped
them from becoming one of the most popular heaters that we sell.
In pub environments, a parasol mounted heater is often an easier option,
however, thought must be given to what happens to these heaters overnight as
often they are in situations where they can be prone to being stolen - clearly
being attached to a parasol is no match for being bolted to a brick wall!
That being said, there are various options available that attach either to the
strutts of an umbrella / parasol or clamp onto the main pole itself. The
Outdoor Electric Heaters that clamp onto the pole itself, such as the
Heatmaster and the Helios Jolly Tris can be very effective indeed. If the
parasol is taken down at night then the heaters would need to be removed to
enable this on each occasion. In these instances another option is the Helios
Top, a small neat waterproof heater that clamps onto the struts of a parasol
and in many instances can stay in situ even when the parasol is closed.
Third option is completely free standing Outdoor Electric Heaters. These are
almost all weatherproof and in the right environment look terrific; however,
one needs to find a suitable means of supplying them with electricity,
especially as in most commercial environments health and safety dictates you
cannot simple leave a heavy cable running over ground to be plugged in. They
also tend to be quite expensive compared with their wall or parasol mounted
counterparts.
We are often asked what height wall mounted Electric Outdoor Heaters should be
placed at. There is no hard and fast rule for this as most of our outdoor
heaters are supplied with brackets that allow the heaters to be angled
downwards for the customers that require the heat. As the heat is largely
directed towards them with little escaping behind, one does not normally have
to worry too much about the heater effecting the ceiling or the canopy under
which it is mounted. The other consideration is how far from the ground
should an Outdoor Electric Heater should be mounted, well again safety is the
only concern and clearly it is better if it can't be touched or interfered
with by customers or their children, however, that being said it is quite
acceptable in many pubs to have a roaring log fire throughout the winter and
clearly this is at ground level!
Where financially practical we would always recommend customers buy heaters
that can generate enough heat for their worst given scenario and then buy a
controller that allows them to adjust the amount of heat given out. In the
same way as you would rarely turn the volume on your stereo up to maximum,
similarly an Outdoor Electric Heater or indeed heaters connected to a variable
controller will allow you or your customers to vary the heat emitted on an
instantaneous basis. Time lag switches have become a very popular accessory.
These allow customers to turn the Outdoor Electric Heaters on at will. The
switches are programmed to allow the heaters to remain on for a fixed period
of time usually set between 10-30 minutes, after which the heater will
automatically be turn itself off, thus saving any wasted heat and of course
wasted electricity. Another option is a PIR (Passive Infrared) controller
which will automatically switch the heater on when it detects the presence of
a person within its given vicinity, this again can be programmed for 10-30
minutes duration and of course if the person is still within its presence it
won't switch off at all.
All the signs are that Outdoor Electric Heaters are here to stay and they can
transform any drab and dreary courtyard into a warm and welcoming environment
in which people can enjoy so much more of the outdoors than was ever
previously possible. In England we are perhaps too used to only using our
gardens, patios and courtyards for a very limited period in the year after
which they are battened down and the doors closed again until next summer,
however, now this is no longer the case. More and more owners of pubs and
clubs are finding that by utilising their outdoor space for a much greater
period of the year they can dramatically increase the revenues gained from
their businesses. This has become all the more pertinent since the recent
smoking ban where those with foresight are making sure they provide
comfortable space for their smoking customers to frequent. Even in home
environment many smokers are choosing to smoke outdoors in their own back
gardens or patios. With an Electric Outdoor Heater they can have instant heat
as soon as the switch is flicked, which can be turned off again in an
instant. This was never possible with gas patio heaters which I strongly
suspect have had their day.
