Of all the heating and cooling options we discussed, the least common are steam boilers. “In steam boilers, which are much less common in homes today, the water is boiled and steam carries heat through the house, condensing to water in the radiators as it cools. Oil and natural gas are commonly used.” On behalf of your St Louis Cooling Service near Hazelwood we want to also cover the boiler dynamics.
As opposed to a fan and duct system, a boiler uses a pump to circulate hot water through pipes to radiators. Some hot water systems circulate water through plastic tubing in the floor, a system called radiant floor heating (see “State of the Art Heating”). There are many important boiler controls, which include the following: thermostats, aquastats, and valves that regulate circulation and water temperature, according to St Louis Cooling Service near Hazelwood. Although the cost is not trivial, it is generally much easier to install “zone” thermostats and controls for individual rooms with a hydronic system than with forced air. We found that cooling and heating controls can be chosen to some extent also. “Some controls are standard features in new boilers, while others can be added on to save energy.”
There are condensing gas-fired boilers and as with furnaces, condensing gas-fired boilers are relatively common, and significantly more efficient than non-condensing boilers (unless very sophisticated controls are employed). The oil fired condensing boilers are much less common in the US for several reasons related to lower latent potential and potential for fouling with conventional fuel oil. Heat pumps will be the next subject we cover on behalf of your St Louis Cooling near Hazelwood MO.
We spoke of atmospheric furnaces in the previous post here on behalf of your St Louis Heating and Cooling Repair near St Louis City. Now, we will move on to talk about condensing furnaces, another component option when using central heating systems to heat your space. Atmospheric have the problem of allowing heat to escape. “Condensing’ furnaces are designed to reclaim much of this escaping heat by cooling exhaust gases well below 140°F, where water vapor in the exhaust condenses into water effectively. This is the primary feature of a high-efficiency furnace (or boiler). When it comes to venting these condensing furnaces, they typically need to vent through a sidewall with a plastic pipe, according to our recent research done on behalf of your Bridgeton Heating installation near St Louis City MO.
We can’t really cover furnace information with you without discussing what we found regarding new furnace standards currently under development by the U.S. Department of Energy. They are due to be finalized in the spring. The current furnace standards had not been updated since 1987 when these were first set out to be revisited and modified.
Moving on to regulation, we found, on behalf of St Louis Heating Installation in St Louis City, that heating system controls regulate when the various components of the heating system turn on and off. The most important control from the perspective of the user, is the thermostat, turning the system on and off to keep you at the best comfort level. The following is true of both home and commercial heating units in St Louis, “A typical forced air system will have a single thermostat. But, there are other internal controls in a heating system, such as ‘high limit’ switches that are part of an invisible but critical set of safety controls. We will go into greater depth over gas furnaces and boilers in the next post here on behalf of your New Bridgeton Heating Repair near St Louis City MO.
In our research on behalf of your heating and cooling experts in St Louis near South County, we have been looking at heating and cooling solutions from multiple angles. Covering the two types of furnaces, atmospheric and condensing is what we just finished doing. Now, we consider that the best gas furnaces and boilers today have efficiency over 90%.
When it comes to efficiency, there is a difference between them. “The efficiency of a fossil-fuel furnace or boiler is a measure of the amount of useful heat produced per unit of input energy (fuel). Combustion efficiency is the simplest measure; it is just the system’s efficiency while it is running. Combustion efficiency is like the miles per gallon your car gets cruising along at 55 miles per hour on the highway.” When it comes to regulations, the minimum AFUE, or annual fuel utilization efficiency, estimates seasonal efficiency, averaging peak and part-load situations. “AFUE accounts for start-up, cool-down, and other operating losses that occur in real operating conditions, and includes an estimate of electricity used by the air handler, inducer fan, and controls. AFUE is like your car mileage between fill-ups, including both highway driving and stop-and-go traffic. The higher the AFUE, the more efficient the furnace or boiler.”
Boilers are an interesting subject and product. They are special purpose water heaters. According to our St Louis Cooling repair near South County, it is true that while furnaces carry heat in warm air, boiler systems distribute the heat in hot water, which gives up heat as it passes through radiators or other devices in rooms throughout the house. Then, when the cooler water is set, it runs, returning to the boiler to be reheated. Hydronic systems are systems that run on hot water. Residential boilers are usually natural gas or heating oil for fuel.
In our research on behalf of your St Louis Industrial Heating near Bridgeton, we have found that there are indeed more than one ways to skin a cat, I mean, heat your space. Beginning with central heat, we plan to take you through the variety of ways both here and in posts to follow. Central heating in St Louis involves a furnace. “The majority of North American households depend on a central furnace to provide heat. A furnace works by blowing heated air through ducts that deliver the warm air to rooms throughout the house via air registers or grills. This type of heating system is called a ducted warm-air or forced warm-air distribution system. It can be powered by electricity, natural gas, or fuel oil.”
Looking inside the gas or oil fueled furnace, we see a sight of fuel being mixed and burned. The flames then heat a metal heat exchanger where the heat is transferred to the surrounding air in an effort to heat the space effectively. According to your St Louis Heating installation near Bridgeton, the air is then pushed through the heat exchanger by the “air handler’s” furnace fan and then forced into the ductwork which is located downstream of the heat exchanger.
According to experts on HVAC news, “At the furnace, combustion products are vented out of the building through a flue pipe. Older ‘atmospheric’ furnaces vented directly to the atmosphere, and wasted about 30% of the fuel energy just to keep the exhaust hot enough to safely rise through the chimney. Current minimum-efficiency furnaces reduce this waste substantially by using an “inducer” fan to pull the exhaust gases through the heat exchanger and induce draft in the chimney.

We mentioned previously and had been focused on the subject of virtual reality in the world of HVAC service in St Louis near Hazelwood MO for a bit now and are going to move forward to discuss details of how virtual reality is in play today both inside and outside of the HVAC world.
We read, on behalf of your HVAC sales in St Louis near Hazelwood, that at the 2017 AHR Expo in Las Vegas, several manufacturers showed off VR capabilities in their booths and explained how the technology is now being used for product demonstrations, sales calls, training opportunities, and more. “Virtual reality is increasing its role in the HVAC industry,” said Amanda Comunale, director of construction piping services, Victaulic Co. “In preconstruction, it’s allowing project teams to visualize the job site in new ways. Technology, such as the HTC lens, gives project teams the ability to visualize clash detection in ways not currently possible in Navisworks. Contractors can fully immerse themselves in the model and truly walk a job site to spot issues and clashes. This technology also gives project managers and field foremen the ability to interact with the model the same way the drawing group is able to in the office.”
The virtual reality that we are aware of stems from gaming and many things that we see in the industry are all indicative of inapplicability to the real world. However, this is a false sense of reality, no pun intended. The truth is, that VR can easily and readily be applied to the world of St Louis HVAC near Hazelwood in all of the facets mentioned above, and then some. All it takes is an active imagination, much like the one that got us there in the first place.
There are many different ways for trends to effect kitchens and the commercial appliance industry. We are here, today, on behalf of your St Louis Restaurant Equipment sales and service near Kirkwood MO to talk about the trends of size. There is something called a macro trend. “Energy costs continue to rise, with back-of-house energy consumption making up more than half of expenditures. According to the National Restaurant Association’s ConSERVE website, the typical restaurant spends 35 percent of its energy dollar on cooking, 28 percent on heating and cooling, 18 percent for dishwashing, 13 percent on lighting and 6 percent on refrigeration.”
There is a devised solution to this problem and it is described below based on facts we gathered in our research on behalf of your St Louis Restaurant Equipment Installation near Kirkwood MO. The solution is as follow: Reducing energy usage has become a top priority for manufacturers, spurred on partly by efforts to meet EPA Energy Star standards. “Energy Star has raised the bar by setting new standards that are higher than before,” according to Landeche. “That is creating an unparalleled number of energy-saving pieces of equipment.” Currently, there are eight categories of equipment, ranging from dishwashers to ovens, that qualify for the Energy Star rating.
These standards, according to many like American Services in St Louis, who have been selling and installing commercial restaurant equipment for many years now, is not a new thing. However, many restaurant equipment manufacturers are always striving for more. And, in many cases, it takes a major rethinking of the product design to make it more energy-efficient. One example we found in our research of commercial restaurant equipment near Kirkwood MO is the development of heat recovery systems for dishwashers and refrigeration units. In these systems, the heat given off by the dishwasher’s waste water or the refrigerator’s condensing unit is recaptured and recycled to preheat the incoming water or air.
We have been on a kick of research and relay on information in the category of emissions and all that the upcoming EPA regulations and mandates for 2020 have in store for us as a community as well as heating and cooling and refrigeration specialists as an industry. Obviously, this is a broad subject that cannot be covered completely in one short article, so we are covering a little at a time here, on this blog, on behalf of your St Louis Cooling Sales and Service near Sunset Hills MO.
Currently, the mandates are described with the following in mind, “The goal was to reduce America’s greenhouse gas emissions in the range of 17 percent below 2005 levels by 2020, if all other major economies agreed to limit their emissions as well. Nearly all federal agencies have had a hand in pushing the Climate Action Plan domestically, but others, like the EPA and the State Department have been active negotiators in ongoing global treaty negotiations.”
We all know about the above mandates, but more than that, are things that are new and directly weigh in on the St Louis Industrial Cooling market. They aren’t a reality yet, however, a global phase down of HFCs is on the horizon. Here is what our St Louis Cooling Installation research told us, and much of it has to do with the rest of the world. “A global phase down on the production and consumption of HFCs is coming as more of the developing world choose the benefits of refrigeration and air conditioning.” The efforts are diplomatic between nations and are still in progress as we all really do want the same end goal to be in sight. “Diplomatic efforts between developed nations are underway in earnest using the regulatory process created by the Montreal Protocol on Substances that Deplete the Ozone Layer. And while the Montreal Protocol on Substances that Deplete the Ozone Layer was convened to address ozone depleting substances like CFCs and HCFCs, the program’s success presents the opportunity to address HFCs.” So, let the world of refrigeration and cooling be on their toes.
We can talk more, if you will, about the movement in the St Louis heating and cooling sales world, about GWP. “GWP is a basic measure of a compound’s potential to trap heat in the atmosphere, also known as the greenhouse effect, when compared to carbon dioxide. R-410A, a widely used HFC refrigerant, has a GWP that is 2,088 greater than carbon dioxide. R-407C, another popular HFC, has a GWP of 1,774.” In order to accommodate the atmosphere and do less damage to our ozone, it is important to find chemicals that do the least amount of destruction. According to our St Louis Heating and Cooling near Fenton, and the research and writing we do on their behalf, it is possible to continue to find refrigerants that cool with less and less damage to our atmosphere.
In global news on this subject, from your heating and cooling company in St Louis we found the following: Later this year policy makers from 197 nations will be meeting in Dubai to finalize an agreement on how to phase down the use of HFCs in developed and developing countries and promote the use of low-GWP alternatives.
A little more than two years ago there was a release in the White House of the President’s Climate Action Plan, which is also very pertinent to this discussion. In it was a regulatory blueprint for the production of cleaner energy, a more efficient transportation system, the promotion of energy efficient appliances and buildings, and the reduction of non-emissive greenhouse gases. The broad scope, or goal of this plan was to reduce (and still is) to reduce the greenhouse gas emissions, bringing them down to 17% less than they were in 2005, all by the year 2020. Stay tuned for further details on how the St Louis Heating and Cooling industry near Fenton can play a role in helping this cause.
In our recent research on behalf of your St Louis Refrigeration Installation and Sales near Jefferson County, we found the following to be true and a great premise to spring from in our next several posts, “Refrigerants are going to be…wait for it…the hot regulatory issue for this industry over the next year.” It seems that there is always something to be maintained, managed, regulated, if you will. For this year, it happens to be refrigerant, but just wait and see what the EPA has to offer in the years to come.
Most of all that we read in our St Louis Refrigeration service near Jefferson County research, all highlighted the fact that the current climate change discussion doesn’t just involve coal fired power plants and other sources of carbon emissions. In fact, the majority of refrigerants used today have a harmful impact on the environment and global efforts to find safe and effective alternatives are starting to take shape and according to experts, it is long overdue.
One writer asserts, “No matter what you believe about global warming or climate change, the leaders of this country and many other nations around the world will be taking steps to control or reduce the amount of carbon released into the atmosphere.” GWP stands for global warming potential and apparently the coolants we use have a high GWP and can, therefore, cause more damage than we want to consider. “The phase-out of HCFCs like R-22 isn’t close to the completion, but the discussion is already moved on hydrofluorocarbon (HFC) refrigerants. Although they don’t come out of a smokestack, HFC gases used for refrigeration and air conditioning systems have a high global warming potential (GWP) when they are released into the atmosphere.” The GWP, according to the facts found in our research on behalf of your St Louis Refrigeration Install and Sales near Jefferson County, is a measure of the compound’s ability or potential to trap heat in the atmosphere, this is also known as the greenhouse effect.
“Virtual reality (VR) was once the symbol of a technologically advanced future that granted users the ability to transport to different worlds, augment their own reality, and develop endless applications in any field imaginable.” It is no longer so mysterious or advanced in the sense that it is out of reach. Virtual reality is showing up in so many different avenues, such as HVAC in St Louis near Belleville IL. When we take a gander at the stats, we can see that the above is definitely true.
Statistics show the following, “the VR industry is growing at a fast pace with revenues from virtual reality products — both hardware and software — projected to increase from $90 million in 2014 to $5.2 billion in 2018. The number of active VR users is forecast to reach 171 million by 2018. According to recent forecasts, revenue from virtual reality head-mounted displays is expected to grow from $685 million in 2015 to $3.89 billion in 2018.”
There are many different companies already working to optimize the VR industry. “Several companies have already introduced VR technology. Sony’s Playstation VR, the Oculus Rift, the HTC Vive, and Samsung Gear VR are some of the biggest players in this burgeoning marketplace.” HVAC industry leaders are looking closely, according to the research we found on behalf of your St Louis HVAC installers near Belleville. VR is being used in a multitude of industries for such things as product demos, sales calls, as training tools in the field and even more. There is no feasible reason why virtual reality won’t be a tool for any and every industry in the near future, including the installation specialists who handle St Louis HVAC service near Belleville.
