Heating Elements in HVAC

heat exchangerLooking at heating in St Louis near Sunset Hills, we realize that is has been some time since we perused the halls of an HVAC explanation, looking for new details to point out surrounding your system in St Louis.  So, today, we stumble upon the heat exchanger. “The heat exchanger is found inside your furnace unit’s housing. This component switches on when the furnace is activated by thermostat to produce warmer temperatures in winter.” The way it operates is to pull in cool air, then heat it and circulate it by way of your ducts and our through your vents.

The heat exchanger pulls in cool air, heats it, and circulates the resulting heated air via your ducts and out through the vents.  The evaporator coil is another important heating component to understand.  It has, basically, the opposite job of the heat exchanger and it acts to cool the air when the thermostat is set lower and cooler during the summer months.  “Located in a metal enclosure on the furnace’s exterior, to the top or side, the evaporator coil works similarly to an automobile radiator to produce cool air, which is then circulated through the ductwork.”

Now, we move onto the condensing unit of your heating and cooling system in St Louis near Sunset Hills.  Connected to the evaporator coil, the condensing unit is installed by HVAC contractors on the outside of your home and filled with refrigerant gas in order to properly operate. “When the refrigerant has been cooled to a liquid by heat exchange with the exterior air, the condensing unit pumps the liquid to the evaporator coil to be evaporated into a gas once more.”  This leads us to your refrigerant lines which carry the refrigerant substance to the condensing unit vaporized in the form of gas and return it to the evaporator coil in liquid form.  In order to be resistant to temperature, these lines are typically made of copper or aluminum.

Baseboard Heaters for Commercial Heating

baseboard heating in PAAmerican Services heating maintenance and repair in St. Louis knows that one alternative to commercial heating is Baseboard heating systems.

A Baseboard heating system can offer efficient heating solutions and requires very little space, operates efficiently and are simple to install.

The electric type baseboard heaters usually require from 500 watts to 2000 watts in power output. This is equivalent to 50 – 200 of square feet of space that can be heated. Using a room to room calculation method, Baseboard heating systems can be designed for commercial heating for businesses requiring additional heating solutions in small spaces such as hallways.

Baseboard heating applications can now be introduced using special baseboard heaters to commercial applications with new technology that is available.  Today commercial spaces such as hotel lobbies and even restaurants can consider baseboard heating as an option that can be customized to fit the space.

Heaters such as electric baseboard varieties work as “zone heaters.”  These are units that can be installed under windows in order to counteract cool air that creeps in through and around the glass.  They can ever be controlled individually through separate thermostats.

“These heating systems are constructed with heating elements surrounded by metal sheaths that are mated together with aluminum fins to facilitate the transfer of heat. They employ a process known as convection, in which cooler air in the room is drawn into the bottom of the heater. Air within the baseboard, element and housing all dispel heat,” says Energy.gov.

If you are looking for alternatives in heating systems for your commercial space next winter, be sure to contact us at American Services located in St. Louis MO and set up a consultation for a quote to find out just how much you could potentially save.

Baseboard Heating 101

heating repair in MOBaseboard heating systems make efficient room heating solutions. Baseboard heating units require very little space and are usually inconspicuous. They operate quiet, safe and are very energy efficient. They are also easy to install.

The majority of electric baseboard heaters put out anywhere from 500 watts to 2000 watts in power output. Using the power output/square feet equation this comes out to be about 50 – 200 of square feet of space that can be heated effectively. Baseboard heating systems can be designed for commercial heating on a room-by-room situation or for supplemental heating in spaces needing additional heat coverage such as offices and hallways.

In addition new technology has allowed for baseboard heating applications to be introduced using special baseboard heaters in commercial applications, such as; sporting venues, hotel lobbies, and restaurants. Baseboard systems can often be designed and custom-engineered to meet any interior layout and size specifications.

Baseboard Operations

Electric baseboard heaters operate as zone heaters. These units are strategically installed directly under windows where the baseboard heaters’ rising air cancels the falling cool air from the window’s glass, and are controlled by separate thermostats within the room where they are installed.

These heating systems are constructed with heating elements surrounded by metal sheaths that are mated together with aluminum fins to facilitate the transfer of heat. They employ a process known as convection, in which cooler air in the room is drawn into the bottom of the heater. Air within the baseboard, element, and housing all dispel heat.

 

There are basically two types of baseboard heaters including;

Baseboard heaters operated by electric current which are individual or single units and are most effective on a per-room basis. They are more efficient than other baseboard heating systems because they make use of the principles of radiation and airflow.

This particular baseboard system can be more efficient than a central heating system by keeping the temperature down in rooms that are not frequently used. For example, baseboard heaters allow one room to be set at a lower air temp, while another room can be set at a higher temp saving energy-raising the comfort level in the space. Central air heating systems cannot duplicate this efficiency.

Electric/hydroid heaters are designed with a metal-sheathed heating element that is submerged in a chemical solution that acts as a heat-transfer liquid and is sealed in a heater-length copper tube with aluminum fins bonded to it.  Copper and aluminum are excellent heat conductors for maximum heat transfer.

Tips for Buying a Used Commercial Range

commercial restaurant equipment in PA Used restaurant equipment is a big temptation for anybody who wants to save money today, and with rising food and utility costs, who doesn’t want to save on expenses? A used commercial range is an attractive proposition for restaurant owners, especially new restaurant owners. However, if you are considering a used commercial range, be sure to properly setup a routine maintenance schedule to get the most out of your investment.

PURCHASING TIPS

Follow these tips when shopping for a commercial range:

– Go with gas. If you have made the decision to buy a used commercial range purchase one that runs on gas! Any piece of gas cooking equipment is pretty reliable if purchased used. This is because they’re designed simply with very few working parts, whereas electric ranges can have heating elements go out, and they’re expensive to replace.

– Top configuration and base type.
There are several different range top configurations to choose from. Be sure to read the product description and find a configuration that suits your needs.

– Inspect the unit. Physically inspect the used Range before you purchase it. This could be difficult if you are shopping online or at an auction. During your inspection check the burner heads and pilot ignition for clogs which is a common deficiency. Also if there is a cabinet or oven base,  check the hinges and seal. A bad seal will decrease cooking efficiency and increase energy costs.

– Call the manufacture with any questions. If you have any questions about the used commercial range, the manufacturer will be able to diagnose any potential problem you see  and provide repair estimates. If the potential repair is too expensive, or repairs cost more than the used price of the equipment itself,  go shopping elsewhere.
