Heating And Cooling With Geothermal Heat Pumps

The term geothermal literally means Earth/Ground (Geo) Heat (thermal). Geothermal, or ground source heat pumps, take advantage of the constant ground or groundwater temperatures. These heat pumps use geothermal energy to heat and/or cool your home.

A refrigerant loop with a compressor extracts heat from one side (the ground) and pumps it to the heating loop in your home. It is essentially the same process that happens in your refrigerator: heat is extracted via a compressor and refrigerant loop from the inside of your refrigerator/freezer and rejected into your house.

In the summer the geothermal heat pump reverses its cycle, if you have an air-conditioning system, and heat from the home is rejected into the ground or ground water.

What makes geothermal heat pumps such a good choice for residential heating and cooling is that they do not depend on outside air temperatures. These heat pumps will heat your home as efficiently on a windy, zero-degree winter day as on a 40-degree day. Provided of course, that your house is well insulated and tight.

Geothermal heat pumps are also a very efficient way for heating and cooling your home. They use 25-50% less energy than conventional heating and cooling systems (Source: US DOE).

Residential applications of geothermal energy systems use water-to-water or water-to-air heat pumps.

Water-to-Water Geothermal Heat Pumps

Water-to-water geothermal heat pumps are generally used for heating only. They replace the gas or oil furnace that you might currently have to heat your home and water with.

It is important to know that heat pumps work most effectively when the temperature difference between the heat source (ground) and heat sink (floor heat or radiators) is small.

Ground temperatures range anywhere from 50 to 75 degF, depending on where you live. This means that geothermal heat pumps are generally not suitable for standard hot water baseboard applications, which are designed for heating water temperatures of 180 degF. Floor heat and low-temperature radiators require water temperatures in the range of 95 to 140 degF.

Some newer heat pump models are now equipped with so-called desuperheaters that can transfer excess heat from the geothermal heat pump compressor to the domestic water heater. Your geothermal heat pump can also effectively and quickly heat water for your bathtub, shower and sinks.

Water-To-Air Geothermal Heat Pumps

These types of ground source heat pumps are generally used when you need air conditioning. The Water is the heat sink, where you reject the heat from the house. The Air is the air that is distributed through your home via ductwork.

Otherwise, these heat pumps function the same way as water-to-water heat pumps. And again, the efficiency of a geothermal heating and cooling system is far better than that of a traditional system.

Important To Know

The first step towards making a geothermal heat pump system be a reliable and efficient heating (and cooling) system for your home is to minimize the heating and cooling requirements with a well-insulated building envelope and strategically placed windows for passive solar gain.

Not only is your first cost reduced, because your system will be smaller. You will also tremendously increase the comfort of your home.

Geothermal heat pump systems are best designed and installed by professionals. It is not recommended to DIY. These systems must meet specific requirements. Especially the piping laid out in the ground, or down to the ground water table, must be designed and installed correctly to ensure that your geothermal heat pump system works as intended.

* No Repairs of Ductwork: Mitsubishi Ductless heating and cooling systems eliminate the extra cost and space needed for ductwork. This saves a significant amount of money when it comes to installations. Ducted Air Conditioning systems also suffer from duct-loss, an actual measure of the wasted heating as the air moves through the ductwork. Ductless systems do not suffer this inefficient problem. Mitsubishi Ductless Mini splits transfer the heat via refrigerant and the heat is ventilated directly to the room itself, not transferred.

* Zone Control Throughout The House: A conventional or standard forced air heating system heats the entire home as soon as the system is turned on. All the rooms connected with ventilation system will get heated regardless of you want or not. Even with the vents closed, the air still travels to these areas of the house via the ductwork. But with ductless heating systems you can specify which rooms to heat and when to heat them. Heat the main living space during the day and then the bedrooms in the evening. Each unit operates independently and can even be programmed via the digital remote controls or your smartphone!

* Single System for Both Heating and Cooling: A Mitsubishi Ductless air conditioning system will fulfill both your heating and cooling needs with one unit! Instead of expensive oil or gas bills in the winter and expensive electric bills in the summer, you can go ductless and have energy savings of up to 30% in some situations!

* No Extra Space Required for Installing Them: It doesn’t matter where you live! Ductless systems can be easily installed anywhere, with less space needed than a traditional air conditioning system.

* Smaller Mechanical Components and Precision Devices: Mitsubishi duct free ac systems have smaller, more efficient motors and technologically advanced mechanical devices which consume less energy than traditional systems.

* Low Electricity Bills: Mitsubishi’s Inverter Driven Compressor Technology avoids cycling which is turning on and off at 100% power. Cycling results in the wasting of electricity. Traditional systems cycle on and off all day long. Ductless systems do not, therefore, they are highly energy efficient.

Improve Your Home’s Heating and Cooling with a New Digital Thermostat

With the arrival of fall comes football, the changing of colors and colder weather. As the temperatures start to drop outside, it is important to make sure that your heating and cooling systems are prepared to keep you warm on the inside. A proper thermostat and HVAC inspection will ensure that your system is up and running to its optimal performance.


Many homeowners may be familiar with the older, more traditional circular thermostats that are in homes today, and while these do the general job of a thermostat (keep your house warm/cold when it needs to be); they do not offer you the options of zoning control and air quality control. Enter the new digital thermostats that are available today. These new thermostats, such as the Trane Comfortlink II, offering homeowners the ability to control how hot/cold it is in certain rooms, the quality of air that is coming into their household and even a digital photo frame! Some of these thermostats can be connected to your wireless internet and show you up to date weather, monitor your systems temperatures and how they relate to outdoor temperatures and also set up scheduling times for when the heating and cooling systems should be on and off. On top of these incredible options, the system also will help you save some money, by allowing you to keep a closer eye on when your heating and cooling systems are on and off.Have a room that no one uses? You can shut off the heating to that room with the thermostat instead of just shutting the vents to that room. In time these new digital thermostats will pay for themselves, and then more.

HVAC Inspection

During this time of year it is important to have a heating and cooling system inspection, not only to help determine if you have any leaks or cracks in your system, but to also ensure that everything is in working order. It is important to note that while checking the filters in your system is important, it should not be considered an “inspection”. A full inspection conducted by a HVAC installer on your heating and cooling system will not only prevent potential damage and breakdowns in the future, but will also give you assurance that your system is running in peak operating condition. A full inspection should cover everything from ensuring that the system is running correctly during a normal cycle to checking carbon monoxide levels near the furnace/boiler and heat registers.

With a new digital thermostat and a heating and cooling system inspection done by a HVAC professional, you can ensure that your home will be warm and toasty during the upcoming winter months and that you will also have extra money in your pocket from the efficiency of your system and thermostat working together.

Top five Ways to Keep Your current Heating and Cooling System

Just a few things you are able to do to help ensure the best operation and comfort from your heating and cooling system.

Notice! Always disconnect the power before removing access panels. There can be a number of electrical power connections. Be cautious while handling components or reaching inside machines.

1. Check your filter every 30 days. Dirty filters will burden your heater, air conditioner or heat pump. Your current filter needs to be changed out or washed, if you have the reusable variety, when necessary. In the event you do use a reusable filter, dry thoroughlybeforere-installing it.

2. Cleanse your pre-filter and collection cells of your electronic air cleaner every 4 to 6 months.

3. Dust your interior coil using a vacuum cleaner and soft-brush attachment. Be sure to get rid of any dust from the top and bottom of the coil. Examine first of all to verify the coil is dry. If you are unable to get the coil clean in this way, contact an expert for service.

4. Remove waste from around your outside condensing unit. In this way it should only require minimal care to function safely. Look into the base pan under the unit from time to time to assist the unit drain correctly. To clean an unclean coil, make use of a brush or maybe a vacuum cleaner with a soft brush attachment for surface grunge. To clean dirt which is deep inside the coil, call a professional for service.

5. Coastal regions have their very own demanding situations for outdoor condensing appliances, which means your machine will require special care. Ocean spray and coastal winds carry salt, which is corrosive to most metals. Although most up-to-date equipment is made out of galvanized metal and protected by way of specially formulated paint, you can increase the life of your unit by means of washing every bared surfaces and the coil each and every 3 months.

These 5 tips can begin you on your journey of saving money by way of proper maintenance of your heating and cooling system.

What you need to know about Heating and Cooling Systems?

Do you want to know more about heating and cooling systems and how they can help out your newly purchased house? Here you can learn about many things about heating and cooling systems and how you can have the most advantages from using them.
Heating and cooling systems are actually central heating systems in the form of a heater or central heating boiler and in typically they are positioned in the basements or garages of our house or property. They’re located out-of-the-way because they are usually big and can release lots of heat while it operates. Individuals are safer away from them. They are able to deliver heat all through our households by pumping in hot air by means of its system of air ducts and can also give steam or hot water using pipes coming from the radiators. In real meaning, they work with the functionality of forced-air and gravity systems and they can be worked throughout thermostat control. Most houses generally use electric baseboard heaters or even in-floor gas heaters that produce radiant heat but now, more and more people are becoming aware of the centralized heating and cooling systems.
For homes, there are two common types of heating and cooling systems and these are the centralized ducted air systems and the radiant heating systems. Ducted air systems are the most common type and you can very easily spot it if you see houses with their ac units, or heater, and heat pump that get hot or cool air from one source. In this system, there are also 2 kinds, the forced-air and the gravity kind. With the forced-air system, you can have hot air from the furnace and you can also have cool air from the air conditioning unit. The ventilator from this arrangement is dependable for these as it forced the cooled or hot air from the whole system and into the rooms of our offices or homes.
The gravity furnace handles by transporting hot air through the system that comes from a heater which is located on the ground or below the main floor. It does not use blowers but it uses huge air ducts and can only supply warm air unlike the forced-air heating and cooling system which is handy.
Now, the 2nd type of heating and cooling system is the radiant heating systems. This system uses water, hot steam or electricity to charge water and make radiant heat and this is made likely by using the central boiler system that heats the water. The steam that’s generated moves around through a structure of tubes and pipes that are located under the house’s floor surface and when these pipes gets warmed up because of hot water and steam, radiant heat is emitted which warm the bedroom.
Electric radiant system is also under this kind of radiant heat. This system works when a house is installed with electric-resistance baseboard or has a system of electric cables and sometimes foils hidden beneath the floors or even above ceilings. When there is the flow of electric current on these components, heat is also generated and radiated inside the room
