Geothermal Heating and Cooling

Geothermal Heating and Cooling

geothermalWhen we are looking into different ways to cut costs both at home and in our commercial business, heating and cooling can be a great area of focus.  There are nonconventional ways to accomplish the heating and cooling that you are looking for that we researched completely on behalf of your Cooling installation in St Louis near Fairview Heights IL.

First recognize that the earth is brimming with a limitless source of energy – also known as geothermal.  The explanation of this begins deep inside our planet where you would find a lot of hot water and steam. The deeper you go, the hotter it gets, in fact. But you don’t have to dig too deep to take advantage of this energy, according to all that we read on behalf of your St Louis Cooling Sales near Fairview Heights IL. Only a few feet below the surface, actually, the temperature of the water remains constant year round, generally about 42 to 80 degrees Fahrenheit (5.56 to 26.67 Celsius) depending on where you live.  A geo-exchange system can use this energy to heat and cool almost any kind of building [source: Minnesota Geothermal Solutions].

Here is further explanation based on our recent research on behalf of your Cooling Service near Fairview Heights IL in St Louis MO.  “Geothermal systems do not directly tap into the heat inside the Earth. Instead, geothermal homes use heat pumps to take advantage of the constant temperature of geothermal wells under the ground. The heat pump can cool a house in the summer and warm it during the winter. Heat pumps have a fluid inside, which could be water or a refrigerant. When it is cold outside, the fluid absorbs Earth’s heat and brings it inside to warm the air.” In the summertime, the heat exchange works in reverse, cooling the house [source: APH Geothermal].

Geo Thermal Heat Pumps

Geo Thermal Heat Pumps

geothermalWho’s familiar with Geothermal heat pumps?  Well, on behalf of your St Louis cooling company near Ladue, we are looking closer at these contraptions and deciding if they are good options to consider in the attempt at heating and cooling in the most efficient way possible.  Along the same lines as duel fuel heat pumps mentioned in our previous write ups on behalf of your St Louis Cooling Installation near Ladue, geothermal technology is a major investment that promises to save you much money over its lifetime. Geothermal heat pumps have been around since the 1940s, so they’re not exactly a new technology. Nevertheless, these products haven’t really caught on until recently and so we will spend some time on them here.

With more homeowners waking up to the importance of going green, and conserving money and energy in the long run, geothermal heat pumps have grown in popularity pretty much everywhere they have been introduced. “A geothermal heat pump gets its energy directly from the earth through an underground looped pipe that absorbs the heat and carries it into the home. When cooling is needed, the process occurs in reverse, with the pump removing warmth in the home. A major bonus of having a geothermal heat pump is the availability of free hot water.”

You will, therefore, want to ask your St Louis Heating and Cooling Installation expert about this water perk that adds value to your entire cooling situation at home. To find out more from an installation, maintenance or sales perspective as to whether or not these geo thermal pumps may work out best for you and your home or business, contact our St Louis Heating and Cooling installers near Ladue for more information on cost to buy and install, as well as expected performance and savings over time.

Heat Pump Particulars in HVAC

Heat Pump Particulars in HVAC

heat pumpWe enjoy the efforts we put forth on behalf of your HVAC installation and repair in St Louis near Overland MO.  One of the best aspects of this job is to learn more about interesting topics and pass along what we discover to others.  Today, we are looking closer and the H in HVAC, which as most of you probably know, stands for heating.  Heat pump seemed interesting, so we first researched the details surrounding those.

There are two main types of heat pumps used in residential and commercial applications: air-source heat pumps (by far the most common) and ground-source (or geothermal) heat pumps. Did you know that a heat pump works like an air conditioner in the cooling cycle?  Then, when it is in the heating cycle, it simply does the reverse, working to cool the outside while venting heat to the inside. A major difference in the two mentioned above, was found during our research on behalf of your HVAC sales in St Louis near Overland, as follows, “Ground-source heat pumps transfer heat through earth or water, whereas air-source heat pumps do so via air. Because heat pumps simply move heat around rather than creating heat, they can be a very efficient method of space conditioning, especially in moderate climates.”

What lets us know the efficacy of a heat pump?  Well, this would be best measured in efficiency compared to yield.  “Heat pump efficiency is rated using two metrics: SEER (Seasonal Energy Efficiency Ratio) is used to rate the performance when the unit is acting as an air conditioner; HSPF (Heating Seasonal Performance Factor) is used to rate the performance when the unit is in heating mode.” In our research, we learned, on behalf of your St Louis HVAC sales, that there is much to be known about efficiency and many ways to dive deeper online.  For now, the above rating system is all we uncovered for time’s sake.  Stay tuned to this site for more posts on heat pumps and more discussion about their efficiency and other surrounding details.

Ductless Is Not Only Great For Cooling

Ductless Is Not Only Great For Cooling

wall HVACWe are here now to continue our conversation regarding ductless systems.  We began research and discovery on the subject as it pertains to efficiency and the latest in technology and options for those of you looking for St Louis Cooling sales near St Peters, but we are here to continue the analysis on heating solutions as well.  According to experts in the field, the following is true, “But it’s time to stop thinking about ductless systems primarily as a cooling solution. With new advancements, ductless systems are an energy efficient source for heating as well. In fact, at least one manufacturer now offers both 9,000 and 12,000 Btu models that deliver 28.0 SEER, with low ambient heat pump performance down to -13 degrees F.”

Ductless systems are an incredible option for anyone who wants exceptional heating and cooling performance and efficiency.  Quite frankly, anyone and everyone should consider making this their way to go in the St Louis heating and cooling realm.  The flexibility you will experience in the cooling installation near St Peters is unbridled and the comfort hits maximum peeks with minimum cost and the most savings throughout the year.

Why are these ductless systems the way to go?  I mean, how do they manage to accomplish all of the things we mention above.  Basically, this is accomplished through great design.  “Ductless systems are designed to be as sleek, slim and unobtrusive as possible, while still delivering extreme efficiency. Homeowners can choose from single-zone cooling models, single-zone heat pumps that cool and heat, and multi-zone heat pumps that cool and heat up to as many as eight rooms on one system. Options include wall mounted units, slim ceiling cassettes and concealed duct units.”  Truly, based on our rather extensive reading and research on the subject on behalf of your St Louis Cooling Installation near St Peters, there is no better way to heat or cool your space than with ductless systems.

The Scoop on Cooling Efficiency

The Scoop on Cooling Efficiency

energy efficiencyLooking even closer at heating and cooling dynamics in our recent research on behalf of your St Louis Cooling installation near Kirkwood MO, we stumbled upon rather interesting information surrounding the air conditioning and heat pump cycles.  “Air conditioners and heat pumps use the refrigerant cycle to transfer heat between an inside unit and an outside unit.”  The only way in which heat pumps differ from air conditioners is the fact that they can reverse by way of a special valve that does not exist for the AC, but does for the heat pump.

Both must operate within specified parameters that dictate a certain maximum level of energy consumption and new efficiency standards for central air conditioners took effect in 2015.  As was true with furnaces, the newer standards differed by region, having greater stringency in the South and Southwest than in the North. According to our recent research on behalf of your St Louis Cooling Repair near Kirkwood, new central air conditioners sold for installation in the South and Southwest must meet a minimum 14 SEER; for units installed in the North, the 13 SEER minimum remains unchanged. Air-source heat pumps must meet the 14 SEER minimum regardless of where they are installed. In addition, central air conditioners installed in the hot, dry Southwest must meet a minimum 12.2 EER (or 11.7 EER for larger models).  These are all numbers found online in our recent research and collected from reliable internet HVAC sources.

It is true that the cooling performance of ground source heat pumps is measured differently.  “In contrast, cooling performance of ground source heat pumps is measured by the steady state EER instead of a seasonal measure. The ENERGY STAR program’s minimum requirements for ground-source heat pumps are 21.1 EER for open-loop systems, 17.1 EER for closed-loop systems, and 16 EER for direct expansion (DX) units.”  We will pick up here later and dive deeper on your St Louis Heating sales and install’s behalf with room air conditioners.  Stay tuned to learn more about BTUs and how to decide just what your room or rooms need in order to keep cool in the hotter months.

SEER and the Heating and Cooling World

SEER and the Heating and Cooling World

researchWhen it comes to heating and cooling we strive to bring you the latest news and information available to the industry on behalf of your heating installation and sales in St Louis near Bridgeton MO.  Today, we flip a coin and go from discussing St Louis Heating Sales to central air conditioners.  “Central air conditioners and air-source heat pumps operating in the cooling mode have been rated according to their seasonal energy efficiency ratio (SEER) since 1992.”  Many people are clueless when it comes to the ratings of their systems and, mainly when they are shopping, this can be quite pertinent information to have.  So, let us describe some of the nitty gritty surrounding these numbers as they pertain to your St Louis Heating and Cooling maintenance and efficiency.

“SEER is the seasonal cooling output in BTU divided by the seasonal energy input in watt-hours for an ‘average’ U.S. climate. Before 1992, different metrics were used, but the performance of many older central air conditioners was equivalent to SEER ratings of only 6 or 7.”  This number has risen over time with the average central air conditioner sold in 1988 having a SEER-equivalent of about 9; then by 2002 it had risen to 11.1.

According to our research done recently on behalf of your St Louis Heating and Cooling sales near Bridgeton MO, the national efficiency standard for central air conditioners and air source heat pumps now requires a minimum SEER of 13, this has been the case since 2006.  Also, you cannot just receive an ENERGY STAR rating without working for it in the heating and cooling world. This title is only awarded to systems who achieve a minimum of 14.5 SEER.  Basically, the point of our post is to recognize the efficiency differences and the fact that they do exist in the AC and heat pump world.  Also, knowing a bit about their significance can and does make you a smarter shopper in the world of HVAC.

Elaborating Further on Heat Pumps and Central AC

Elaborating Further on Heat Pumps and Central AC

defineMoving onto the second phase of description we are planning on behalf of your St Louis Heating and Cooling installation near Fenton MO, we still have much to explain about your cooling system in your home.  Your air conditioner, to be precise, and though we told you the basics when it comes to the system and how it uses energy to remove actual heat from your space, unfortunately, it isn’t quite that simple.  The process gets quite a bit more complicated with all the controls and valves involved, its effect it rather amazing.  “An air conditioner takes heat from a cooler place and dumps it in a warmer place, seemingly working against the laws of physics. What drives the process, of course, is electricity — quite a lot of it, in fact.”

Our first type of cooling system to discuss, namely because it is the most common, are the central air conditioners and heat pumps designed to cool the entire house. “In each system, a large compressor unit located outside drives the process; an indoor coil filled with refrigerant cools air that is then distributed throughout the house via ducts.”  Heat pumps are then like central air conditioners with the exception of the cycle direction variations.   “Heat pumps are like central air conditioners, except that the cycle can be reversed and used for heating during the winter months.”  We will go into more details on behalf of your St Louis Heating and Cooling sales near Fenton, in regards to heat pumps below.

With a central air conditioner, the same duct system is used with a furnace for forced warm-air heating. In fact, the central air conditioner typically uses the furnace fan to distribute air to the ducts, so there is an overlap and therefore efficiency existent in the system by its simple nature.  Central air conditioners and air source heat pumps in their cooling mode of operation are rated according to their efficiency in the seasons.  We will break down these details in the next couple posts here, on behalf of your Heating sales in St Louis near Fenton MO.

Heating and Cooling in St Louis

Heating and Cooling in St Louis

coolingOf 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.

HVAC Roof Standards for Energy Savings

HVAC Roof Standards for Energy Savings

rooftop HVACWriting on behalf of your St Louis HVAC Maintenance near Chesterfield, we have uncovered some very fresh and equally as interesting news to pass your way today.  “The HVACR industry has less than one year to prepare for what the government has deemed the ‘largest energy-saving standard in history’ as the U.S. Department of Energy (DOE’s) energy conservation standards for commercial air conditioners and heat pumps and commercial warm-air furnaces, otherwise known as rooftop units (RTUs), are scheduled to take effect Jan. 1, 2018.”

When it comes to HVAC installation near Chesterfield, apparently all installers as well as sales and commercial repair companies will have to know these standards and keep them in their back pocket, so to speak, at all times.  The rooftop air conditioner standards, such as the ones on low-rise buildings, as in hospitals, schools, and big box department stores will take place in two phases, increasing minimum efficiency by about 10 percent as of Jan. 1, 2018, and by 25-30 percent as of Jan. 1, 2023. Also effective in 2023 will be the standards for new warm-air furnaces that are typically installed in conjunction with commercial air conditioners.

In our HVAC installation in St Louis near Chesterfield research project, we found that there are estimates based upon other estimates, such as the DOE saying that the new rooftop air conditioner standard will save 1.7 trillion kWh over 30 years of sales.  This is actually estimated (once again) on the amount of coal burned in the US to generate electricity for the entire country for one full year.  This is supposed to go beyond any other standard set in place by our government, or any other government for that matter.  We will pay attention to how this plays out, but for now, we simply wanted to relay the information to you, the commercial HVAC consumer.

More Efficient HVAC Systems

More Efficient HVAC Systems

HVAC installSome of the latest technologies that will directly impact exactly how efficient your Commercial HVAC in St Louis can be, are as follows:   variable speed compressors, electronic expansion valves, advanced humidity removal, heat recycling, variable frequency drives, and thermal energy storage.  Essentially, the above list consists of things that can be done to modify your current HVAC system and add efficiency to it, according to your St Louis HVAC near Bridgeton MO.  This is the most cost effective way to improve upon an existing HVAC system in your commercial setting, in order to allow a huge gain in efficiency which will result in a savings for you and your business.

The above observation is proven through research and questioning of those in the mix, “While some builders and owners will choose to install whole new, cutting-edge HVAC systems, occupants and building managers will favor lower-cost incremental component solutions that improve efficiency of their existing systems,” said Jaideep Raje, a Lux Research senior analyst and a contributing author of the report. “Component technologies demonstrate the quickest return on investment, smoothing their path to adoption.”

The above report was done and used by evaluating current HVAC systems and separate components, scoring them individually, according to your St Louis HVAC Sales and Service near Bridgeton.  “The report evaluates HVAC systems and components separately and scores technologies on their technical value and maturity. It then plots each technology’s relative potential on a matrix comprising four quadrants: Current Winners, Future Winners, Long-Shot, and Faded Incumbents.”  Some of the specific findings will be written about here, in future posts, and they show a ton of potential in the world of HVAC efficiency.  We will concentrate, next, on heat pumps and how they can positively impact the cost of operating your commercial HVAC system in St Louis MO.
