Air-conditioning is one of a handful of technologies that has utterly transformed the way we live. Throughout history people have tried to stay cool during hot months of the year. From ancient Persians using systems and wind towers to Chinese during the Han Dynasty using rotary fans and Egyptians using ventilators as well as Mad King Ludwig using air cooled by water from mountain runoff. In 1902 Willis Carrier invented the first modern air-conditioning system powered by electricity. Developed to control temperature and humidity in manufacturing plants primarily in the printing industry, this innovation has become a must-have for most businesses and homes in the US and in many countries around the world.

Today

Carrier air conditioners

are found worldwide in applications from heavy industrial to home and automotive systems. Having owned several Carrier air conditioners I can personally vouch for their reliability and performance. Our most recent acquisition in the carrier line is a Carrier hybrid heating system which combines an air conditioner/heat pump and a high efficiency gas furnace.We have had this system in place now for three years and could not be happier. It has substantially lowered our heating and cooling bills and has operated flawlessly.

The Carrier hybrid heat system, in conjunction with the infinity control set allow flexibility not available to the typical HVAC system. During times of moderately cool weather that heat pump functionality of the carrier air conditioner allows heating of your house by electricity only. With today’s heat pumps this can be much more economical than even a high efficiency gas furnace. This works by reversing the normal air-conditioner functioning and extracting heat from the outside air to heat the house. As temperatures drop this becomes less efficient and at a certain temperature the system will switchover to the gas furnace. This gives great flexibility in how your home is heated and can provide substantial savings over using a gas furnace or electric resistance furnace.

Another advantage I discovered after putting the system in was the ability to buy electricity from our utility at demand prices. Since electricity prices fluctuate during the day and are normally very low at night when much of our heating demand occurs in the spring and the fall it has further reduced our overall utility costs.

For anyone considering installing a new HVAC system I highly recommend Carrier air conditioners and heating systems.

How does geothermal heating work

Though geothermal heating has been proposed as a potential technology to clear up the worldwide energy crisis, many of us are not aware as to how does geothermal heating system work. In this heating system, air is circulated from within the Earth’s surface to heat or cool a house.

Geothermal heat pertains to heat kept within the Earth’s surface. The term geothermal springs from the Greek words, geo for Earth and thermos for heat. As per evidences, heat energy in the deep underground results from the rot of radioactive particles and assimilation of solar heat. The average temperature of geothermal heat is fifty – 70 degrees Fahrenheit. This geothermal energy can be used as an alternative power source for heating houses and household appliances.

Geothermal Heating

Geothermal heating is an complicated leading edge technology implemented for clearing up the worldwide energy crisis. It makes use of geothermal energy for heating or cooling applications. As of now, it has succeeded in providing more than 0.07 p.c of the global power usage. In a geothermal heating system, the heat power contained inside the Earth’s surface is utilized for heating purposes. It’s also referred to as ground source heat pump. The standard geothermal heating system has the capacity to heat up a building without other heating appliances. Let’s see in a nutshell how does geothermal heating system work.

Working of Geothermal Heating System

For better understanding of the working of a geothermal heating system, first let’s discuss about its main components. In this heating system, there are 3 primary parts, particularly, a geothermal heat pump, ground loop system and a distribution system. The geothermal heat pump is installed within the house or property, while the ground loops or pipes are configured under the Earth’s crust at a specific depth. The depth of the piping depends upon the possibility of geothermal heat in the particular area.

How does a ground source heat pump work

The pipes of the ground loop are connected to the geothermal heat pump and the distribution system is configured as specified in the obligation of the user. The heat pump forces a liquid refrigerant or cool water into the pipes of the ground loop, which is then circulated underground. The refrigerant is warmed up naturally due to geothermal heating inside the Earth’s surface. The heated water is circulated back to the heat pump that exchanges the heat by employing a heat exchanger. This heat exchanger then circulates warm air inside the house via the distribution system.

Speaking about the uses of geothermal heating system in warmer months, this may be operated for cooling a home like air conditioners. The working principle of the system is reversed so that heat exchanger now supplies cool air in the house. For setting the specified temperature, an electronic thermostat is configured in the system, which heats or cools the house accordingly . This is in brief an answer to how does a geothermal heating system work.

Since the heat exchanger is operated by using electricity, the final working of geothermal heating system consumes some amount of energy. Nevertheless, it is terribly inexpensive to use geothermal heating in comparison to other heating systems. Geothermal heating system is more successful in areas that lie close to the plate tectonic limits. Over these regions, the heat-laden magma often rises near to the earth’s surface. In such cases, geothermal heating can be effectively used for heating water.

One of the major advantages of geothermal heating is that it is renewable and eco-friendly. It is replaceable since heat trapped inside the Earth’s surface can be used for both heating or cooling purposes. Also, unlike any other traditional heating appliances, operation of geothermal heating system doesn’t emit toxic gases or pollutants.

Is your heat pump in a need for repair? Are you facing heat pump problems? If yes, then go through this article to understand the tips for troubleshooting heat pumps.

Heat Pump Problems : troubleshooting heat pumps
Heat pumps are the mechanical devices that are configured for transferring heat from one location ( source ) to another ( sink ). In almost all of the cases, heat pumps draw heat either from the atmospheric air or from beneath the Earth’s surface. The former type is called air source heat pump, while the latter machinery is called geothermal heat pump. Heat pumps serve for both cooling and heating the home in extreme environmental conditions.

The technology of heat pump is utilized in some home appliances such as heating system, freezers and air conditioners. A heat pump works by consuming a touch of energy for transferring heat from an area with low temperature to another with a higher temperature. It is more energy efficient compared to heating and cooling devices like furnaces and ACs. Nonetheless like other machinery, there are certain heat pump issues, that may arise over a time period. Let’s discuss in detail about troubleshooting heat pumps.

Troubleshooting Heat Pump Problems

A brief knowledge about the parts of a heat pump will help in an easy diagnosis of the heat pump Problems. The basic components include an evaporator ( circulating fans ), reversing valve, condenser ( fridge coil ) and a compressor. Prior to beginning with heat pump troubleshooting, switch off the power supply at the main circuit breaker. Following are some of the common heat pump issues and paths to troubleshoot them :

No Heat Production : If there is no heat production, then the problem may be because of failure in the main power supply or overloading of the motor. In order to troubleshoot this malfunction, check the power supply and thermostat and fix them ( when necessary ). In case there’s power supply, reset the motor by pressing the reset button. Also, check the ignition of the heat pump for any defects. If none of these tips work, then you can hire a professional for proper fixation.

Insufficient Heat Production : inadequate heat production is one of the major heat pump issues. Mostly, it is caused due to obstructions in the air ducts. Other reasons for this defect may be low thermostat setting and presence of mud in the air filters. You can check these systems whether they are working properly or not.

High and low Head Pressure : A heat pump difficulty with low head pressure can be due to a scarcity of refrigerant, damage of the compressor and dirty evaporator. On the contrary, high head pressure frequently results from overfeeding of the refrigerant and mucky condenser. Keep an eye on these systems and recheck whether the heat pumps start working normally or not.

Freezing of Heat pump : Freezing of the heat pump unit might be caused thanks to a faulty air blower or accumulation of dust and dirt in the filters and evaporators. For fixing this problem, check for the unfreezing option in your heat pump unit. If there’s, you can defrost it and check the compressor for any defects. Do not forget to check the calibration of the thermostat.

Noisy Heat Pump : noisy functioning of the heat pumps is caused thanks to the reasons like loose screws, improper fixation of the belts and noise from the air channels. To fix and troubleshoot this malfunction, you can tighten the screws, check the belts and introduce a plastic insulation inside the metal air ducts.

Are you thinking about buying a pool heater? A very cost effective option would be getting a pool heat pump cover. Solar heaters don’t require any additional source of energy, so it’ll heat up your pool for free.
Solar heater for swimming pools – how does it work?

Unlike other sorts of solar powered devices, solar pool heater works rather straightforward. Solar panels collect heat from the sun. They are usually installed on your roof or next to the pool. A pump forces water from your swimming pool thru a filter that leads it into a solar collector. The water heats up in the collector then returns into the pool thru the pump.

This won’t let you swim in Jan, naturally. But it’ll make swimming snug when the weather just turned to be too cold for a snug swim. In climates with cold winter, installing a swimming pool heater can bring your swimming season up to five, six month a year, when without it you would only swim two or three month. In general, on a bright day a solar heater can raise your pool water temperature by seven to ten degrees.

How big a heater is needed and how much will it cost?

The dimensions of a swimming pool heater you need relies on the size of your pool and the climate in your aria. For bigger pools and colder places you want bigger solar heaters. The cost of your heater is usually proportional to its size. Heaters with 2′x20′ panels are the hottest. The price is about 150 bucks per panel. A set of two panels will keep an 18′-24′ pool warm. For bigger pools you will need more panels.

Installing your solar pool heater

Unlike solar water heaters, pool heaters are fairly simple to install. Each set should come with instructions. First you connect the panels to a pump. Than place the panels where the sun can heat them up. You can mount the panels to your roof or position them by the pool using frames available from the dealer. Initially you will notice the panels get very hot, but after a few minutes they’ll cool down.

working on your solar heater for pool

Your heater doesn’t essentially need any upkeep. However it’s critical to keep balanced water chemistry. Also check the filter once in a while to reassure that it is working properly.

Getting a solar heater for your pool makes much more sense than getting any other kind of pool heater including gas and electrical heaters. After you install your solar heater for swimming pool there will be no necessity to pay for energy to heat up your pool, the sun will work for you. You can also buy home heat pumps and cooling for your house.
