The term geothermal literally means Earth/Ground (Geo) Heat (thermal). Geothermal, or ground source warmth pumps, take advantage of the fixed ground or groundwater temperatures to condition 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 basically the same process that happens in your refrigerator: heat is extracted by way of 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. While in an air-conditioning mode, warmth from the house is rejected into the ground or ground water.
What makes these programs such a good selection for residential heating and cooling is that they do not rely on outside air temperatures. They’ll hold your private home comfortable as effectively on a windy, zero-degree winter day as on a forty-degree day. Supplied in fact, that your house is effectively insulated and tight.
Geothermal warmth pumps are also a very efficient and a properly-designed system will use 25-50% less energy than typical heating and cooling techniques (Supply: US DOE).
Water-to-Water Geothermal Heat Pumps
These types of methods are typically used for heating only. They are installed instead of a traditional gas or oil furnace to maintain your property warm and provide home hot water.
You will need to know that warmth pumps work most efficiently when the temperature distinction between the warm source (ground) and the warmth sink is small.
Ground temperatures range wherever from 50 to seventy five degF, depending on the place you live. This implies that geothermal warmth pumps are generally not suitable for standard scorching water baseboard purposes, which are designed for water temperatures of a hundred and eighty degF. Flooring heat and low-temperature radiators require water temperatures within the range of 95 to 140 degF.
Some newer models are now geared up with so-called desuperheaters that may switch excess rejected energy from the compressor to heat domestic water for your bathtub, shower and sinks.
Water-To-Air Geothermal Heat Pumps
These types of ground source warmth pumps are usually used once you want air conditioning. The ground “water” is the warmth sink, the place you reject the heat from the house while in air-con mode. While in heating mode, energy is extracted from the ground water and “pumped” into the “air” pompe de caldura sol apa pret by means of the compressor. The “air” is distributed by means of your house via duct work.
Otherwise, they operate the identical method as water-to-water heat pumps. And once more, the efficiency of a geothermal heating and cooling system is far better than that of a traditional system.
Important To Know
Step one towards making a geothermal heat pump system be a reliable and environment friendly heating (and cooling) system for your home is to attenuate the heating and cooling necessities with a nicely-insulated building envelope and strategically positioned home windows for passive photo voltaic gain.
Not only is your first value reduced, because your system will probably be smaller. Additionally, you will tremendously enhance the consolation of your home.
These highly environment friendly and reliable techniques are finest designed and put in by professionals. It’s not recommended to make this a DIY project. These methods should meet particular requirements. Especially the piping specified by the ground, or right down to the ground water table, must be designed and put in accurately to make sure that your geothermal warmth pump system works as intended.
