FAQ – Patio Outdoor Heating

If you have your own questions on outdoor patio improvement systems, including outdoor heat, please submit them here!

What is the lowest temperature that outdoor patrons can be seated comfortably?

There are several factors that affect heating an outdoor environment. Most critical of these factors is the wind. Better protection from the wind results in comfort at lower outdoor temperatures. With little or no protection from the wind, a practical comfort limit is about 40-45 degrees with wind at 10 mph or less. With good or complete wind protection, year round use of the outdoor environment is achievable.

How much does an outdoor heating system cost?

There are many factors involved in the design, selection, and pricing of an outdoor heating system. The simple reason for this is that every outdoor environment is unique both in size and in the amount of wind protection it provides. Also a factor is the way you intend to use your patio. Answering a few simple questions can give us the information we need to promptly provide the pricing information you’re looking for.

How long does it take to get an outdoor heating system installed?

We maintain a stock of heating systems and equipment in our warehouse in Wisconsin. Equipment can be shipped or brought to your facility within days. Installation can take place in 1-2 weeks afterwards.

What are the different types of outdoor heating systems?

There are various types of patio heaters and patio heating equipment. The main differences are fuel/energy type and configuration. They are summarized below:

        • Can Be Modulated: yes
        • Operating Cost: high
        • Effectiveness: poor-uneven distribution of heat (unless “extra” units are used driving up first cost)
        • First Cost: high
        • Other: three phase power is usually required, intense pink/orange glow illuminates patio

4. Infrared Tube System (Awning Sun)

        • Description: an above mounted tube/reflector system, heat is emitted from steel tube, no glow
        • Fuel Type: natural gas
        • Type of Heat: low intensity infrared
        • Configuration: heat is emitted from a aluminized steel tube that traverses the entire heated area in a large rectangular pattern
        • Can Be Modulated: yes
        • Operating Cost: low
        • Effectiveness: excellent-even distribution of heat over entire area
        • First Cost: high
        • Other: stainless steel/aluminum construction provides excellent product longevity in an outdoor environment

 

What will it cost to operate an outdoor heating system?

There are several factors involved in determining an operating cost for your patio heating system. Most important is fuel type (natural gas, propane, electric) and the length of time you choose to operate your system throughout the year. Natural gas is by far the most desired fuel and will produce the lowest operating cost. We have computer programs that can calculate and compare the operating costs of any of the fuel/system types to give you an accurate estimate of your operating cost based on your desired usage.

What is a typical payback time for a patio heating system provided by Patio Enhancement Group?

Although circumstances vary greatly, our experience has shown that our systems can typically be paid for (with increased patio revenues) in one or two seasons or in less than one year. Our RevCalc® computer program can assist you in determining your increased revenue potential and payback time according to your particular circumstances.

My patio has no awning, pergola or other type of cover. Can I still use an outdoor heating system?

The answer is YES! In order to do so, we would propose a steel “clear span” system to support the heating units. An alternative would be side wall mounting of the units. Be sure to check our picture gallery page under the “Uncovered Patios” or “Side Wall Mounting” sections to get an idea of how we do this.

Do your heating systems require venting or vent pipe?

Venting (a means to remove products of combustion out of an area) is only required when the patio or outdoor environment is fully enclosed as it would be with, for example, an awning covered patio with full side flaps. Patios with only partial or no cover do not need to be vented.

Are you able to direct an installation crew supplied by the owner?

Yes, as one of the many services we provide, we can provide management and direction of your own contractors or workmen. This way we are able to provide a full one year warranty on the complete installation. If desired, we can also provide complete installation services.

What is the typical life span of your heating systems?

Yes, as one of the many services we provide, we can provide management and direction of your own contractors or workmen. This way we are able to provide a full one year warranty on the complete installation. If desired, we can also provide complete installation services.

What is the typical life span of your heating systems?

Being rated for outdoor use, our systems can handle the elements and still provide reliable service for 10-15 years.

What differentiates your system from the familiar mushroom patio heater?

The often seen”mushroom” style propane patio heaters, although boasting a low first cost, fall hopelessly short of the goal of providing even heat around a patio at a reasonable operating cost. Considered a “high intensity” propane fired infrared heater, these units emit a large quantity of heat from what is virtually a single point making it almost impossible to spread that heat evenly around the patio. The high cost of propane as its fuel makes it even more undesirable, not to mention the labor cost associated with having to constantly change the propane tanks. Lost patio floor space is yet another issue, depending on how the units are placed.

Our systems use a natural gas fired low intensity “tube” that runs the length of the patio to evenly distribute the heat. This heat can be modulated to match the conditions of the day and save energy.  The units mount above the patio, out of the way, not taking up valuable patio floor space. By using natural gas for fuel, you can expect an operating cost one eighth that of the propane “mushroom” heaters.

Can your system be left in the elements for extended periods?

Yes, once installed, our systems remain outdoors permanently. The weatherproof stainless steel/aluminum construction allows them to be rated for outdoor installation and provide reliable service for the next 10-15 years.

Why is modulation such an important feature of your outdoor heating systems?

Just as heating systems for buildings are sized for a worst case outdoor temperature, outdoor heating systems are selected for a worst case patio temperature. For instance, if you intend to use your patio at say 40 degrees or above, we will design enough heat into your system to meet that requirement. But when operating the system on a say a 55 degree day, you would have too much heat so we must modulate the heat downward to maintain the comfort of your patrons. Remember, sometimes too hot is just as bad as too cold! As an added bonus, modulating the heat also saves energy which lowers your operating cost.

How do electric infrared heaters compare to your natural gas heating systems?

Much like the propane “mushroom” heaters, electric infrared heaters are considered “high intensity” and emit their heat from virtually a single point making it almost impossible to spread the heat evenly around the patio. Because they are electric, they do heat up faster than a natural gas unit but this comes at the price of much higher operating costs. Our systems use a natural gas fired low intensity “tube” that runs the length of the patio to evenly distribute the heat. Using natural gas for fuel, you can expect an operating cost one fifth that of the electric infrared heaters.
