Using Solar Power in your overall Energy Plan

Using Solar Power in your overall Energy Plan

solor heating in MOAmerican Services HVAC heating and cooling in St. Louis knows that one of the most economical and environmentally ways to heat a building is to use solar power.  And since this green technology has advanced exponentially over the years it has become even more effective and costs less than ever before.

One of the easiest applications for solar power is to use it for the heating of all water in a commercial facility.  Hot water usage can come from showers, bathrooms or even cleaning and manufacturing.  The old fashioned way to heat water has always been by using a water heater that is either powered by propane, natural gas or some other fossil fuel.  The problem with all of these fuels is that there isn’t an endless supply of any of them and therefore the cost to a business can be daunting.  Additionally as fossil fuels become more and more rare and the techniques used to mine them become more expensive the cost is going to continue to rise.  The advantage of using solar power is that it’s a fixed cost with a onetime initial expense and then just maintenance from that point on.

The process to get this all started for a commercial application is fairly simple.  Evacuated tube collectors or a similarly designed solar panel is placed on the roof or high point near the building.  This tube design is particularly important because the solar panels are always facing the sun no matter what angle the sun is at or the time of day.  In addition the simplistic design is solid and offers years of practical use.  The energy is then captured in a solar collector and through a series of tubes and a central controller; the heat is pushed throughout the facility.  This design can be used in a variety of geographic areas and can be just as effective in the winter as it is during those dog days of summer when the sun is always around.

Using a solar panel system to heat water for a commercial building is not only smart business but is good for the earth as well.  Solar energy has been around for years, and continues to supply companies around the world with simple, fast and cheap energy.  If you’re looking to cut costs out of your business and need a simple and time tested solution then solar power might be just what you need.

Heat Pump Are Viable Options for Commercial Heating

Heat Pump Are Viable Options for Commercial Heating

industrial heating service in MOIn most cases heat pumps are used to heat and cool spaces.  However, in other instances they can be used to heat up water as well. Heat pumps can just heat the water or can be used to heat and cool spaces in tandem. Heat pumps use electricity to displace heat, rather than generating heat directly. For this reason, they can often be a good, efficient option for temperature control and for water heating.

A stand-alone heat pump water heater extracts warmth from the surrounding air and displaces it at a higher temperature into a reservoir where the water is then heated. Heat pump water heaters require setup in spaces that stay in the 40 to 90 degree Fahrenheit range. Furthermore, at least 1,000 cubic feet of air space is required for the pump to work properly. Beyond that, heat pumps will not function well in cold spaces, as they tend to cool when they operate already. Installing a combination heating, cooling and water heating system would mean pulling heat indoors from the outside in the winter and from the indoor air in the summer. That being said, any air-source heat pump system works better in a warmer climate.

Geothermal heat pumps pull up heat from the ground in the winter and from air inside during summer months, for heating and cooling. In order to heat water, a desuperheater can be used along with the geothermal heat pump. This device is a small heat exchanger that pulls superheated gases from the heat pump compressor to heat water. The water then gets stored in a water heater storage tank for usage on demand.

Types of Commercial Heating Options

Types of Commercial Heating Options

commercial heating repair in MOAmerican Services heating systems installation in Missouri knows that installation of commercial heating systems using sustainable resources are a viable option that should be considered. These systems employ energy sources such as solar and geothermal power, leaving no footprint on our environment.

Heating, ventilating, and air-conditioning (HVAC) these systems are not only good for the environment, but over time they will perform more efficiently, generating energy cost savings and decreasing the carbon footprint that “traditional”options such as oil and gas leave behind.  Because of the relatively high initial installation costs, this type of commercial heating system is often reserved for the larger facilities.  Fortunately these costs are becoming more affordable as tax breaks and government incentive programs become more prevalent.

Oil or Gas Steam Heating Methods

Choosing an oil or petroleum steam powered commercial HVAC system, while definitely not the most efficient, is one of the oldest methods of commercial heating installations. The oil or gas is used to boil, manufacture and subsequently pass steam through the pipes-generally considered one of the least efficient processes, and at the same time, most harmful to the environment. Steam heating methods take longer than most systems to circulate heat because of the delay between the boiler being fired up, and the heat finally circulating thru a network of pipes, ending up in the radiator unit.

Gas or Oil Water Systems

An additional method for heating commercial property is using a water-driven HVAC system. Similar to steam heating in overall concept, the water heating method uses a boiler to heat water, which is then subsequently passed through a pipe network to radiators positioned throughout the facility. These water heating systems are some of the least productive heating methods and also less than ideal from an efficiency perspective. One reason for this is that you have to clear the air in the system each time the heat is engaged, causing delays in heating which results in inefficiencies.

Heat Pump Alternatives

Implementing a heat pump commercial heating alternative is the most favorable commercial heating option and is an efficient means of heating a building. This process is similar to the technology used in refrigerators, essentially extracting heat from cold. Because these types of systems do not require a fuel source (gas or oil) to function, they are very cost effective systems.

Radiator Heating Systems

Radiator Heating Systems

heating installation in MOAmerican Services commercial heating service near Webster Groves knows that there are two commonly used types of radiator systems for heating commercial installations; steam systems and hot water systems, or possibly a combination of the two.  The type used in your workplace may vary based on needs, structure size and materials available when the structure was built. Construction methods and practices varied greatly over the years. Regional building differences may also play a role in what type of system you have.

Steam

Steam radiator systems use a boiler to boil water to create steam, which in turn moves through a series of piping without the need for pumps.  One of the problems with this systems is you must wait for the steam to warm back up after shutting down.  This is considered an inefficient method.  Steam generally moves around the heating system at pressures of around 1 lb. per square foot, allowing radiator temperatures to reach up to 215 degrees F.

Water

Hot water heating systems heat water in a boiler before pumping the water around the system to heat radiators within a building. Hot water heating systems are commonly used in newer built commercial installations and residential applications and the water temperature in the system is usually limited to 180 degrees.

Formula

If you’re interested in calculating the temperature of each radiator within a heating system, the equivalent direct radiation is multiplied by the amount of heat produced by a boiler per hour. The EDR is the square footage of the radiators within a home, while the heat produced by a boiler is measured in British thermal units. Steam boilers produce around 240 BTUs and hot water boilers produce about 170 BTU’s.

heating services in St. Louis American Services heating commercial heating repair in Saint Louis knows that installing commercial heating systems using sustainable resources is a great option. These systems employ energy sources such as solar and geothermal power. Heating ventilating and air conditioning (HVAC) options are not only good for the environment, but over time will be more cost efficient than more traditional options such as oil and gas.

Because the installation cost of HVAC systems are relatively high, this method of commercial heating system is often reserved for larger businesses.

– Oil or gas steam heating methods.
An oil or gas steam commercial HVAC system while not the most efficient, is one of the oldest methods of heating commercial properties. The oil or gas is used to boil, condense and subsequently past steam through the pipes. This is considered by many in the industry to be one of the least efficient processes. Steam heating also takes longer than most systems to circulate heat.

– Gas or oil water systems.
Heating commercial property using water based HVAC systems is another option. Similar to the steam heating in concept, the water heating method uses a boiler to heat water which then passed through to radiators positioned throughout the property. Water systems are rated less than ideal from an efficiency  perspective. One of the primary reasons for this is that you have to clear the air in the system each time the heat is engaged causing delays in heating and efficiency.

– Heat pump alternatives
Implementing a heat pump commercial heating alternative is an efficient means of heating a building. This process is similar to the technology used in refrigerators, essentially extracting heat from cold air.  For example, consider how warm the coils on the back of your refrigerator get.  The process works by using a refrigerant and subsequently pumping the heat generated throughout the commercial property.

– Commercial heating selection tips
Many HVAC professionals suggest calculating the expense for the first several years of ownership of your new commercial heating system, not just the installation cost, to help determine those that are truly most cost effective. You can reduce these costs by using high efficiency systems. The systems have high annual fuel utilization efficiency ratings(AFUE) and an Energy Star Seal of Approval, Rebates are frequently attached to these systems from government issuing agencies. Heating systems may vary, a temperate climate may warrant a different system than one with extreme temperatures during the winter and summer months.

Heat Pumps for Heating and Cooling Buildings

Heat Pumps for Heating and Cooling Buildings

heating services in MissouriAmerican Services Heating Installation in St. Louis knows that heat pumps for heating and cooling buildings are separated into four main categories depending on the operation being utilized.  These four categories include;

  • Heating-only heat pumps, providing space heating and/or water heating.
  • Heating and cooling heat pumps capable of providing both space heating and cooling. Probably the most common type is the reversible air to air heat pump, capable of operating in heating or cooling mode. Commercial/ institutional applications require a much larger heat pump that incorporates water loops (hydronic) for heat and cold distribution that is capable of providing heating and cooling operations simultaneously.
  • Integrated heat pump systems, providing space heating, cooling and water heating, also capable of recovering exhaust air heat.
    Water heating can be achieved by desuperheating only, or by  desuperheating and condenser heating. The latter process allows water heating when space heating or cooling is not required.
  • Heat pump water heaters which are fully dedicated to water heating. This process most often utilizes air taken from the immediate environment as a heat source. Other options are: exhaust-air heat pumps, or desuperheaters on air to air and water to air heat pumps.

Heat pumps can be obtained in both monovalent and bivalent functions where monovalent heat pumps meet the annual heating and cooling demand without assistance from other heating alternatives.  While bivalent heat pumps are calibrated for 20-60 percent of the maximum heat load and meet around 50 to 95 percent of the annual meeting demand. In larger buildings the heat pump maybe used in tandem with a cogeneration or alternative system that compliments the heating and cooling requirements.
