Ground Source Heat Pump Installation

Without carrying out a full building heat loss analysis, and calculating its related energy consumption profile and the hot water requirements of the buildings occupants. You cannot accurately design a ground source heat pump system.

The main problem with many renewable energy installations is, that compared to normal energy systems such as gas/oil or electric, the installed costs are generally much higher, thus meaning the economies of scale are more limited. An oversized Heat pump will spend most of its time running under part load conditions, which can result in a shortening of the equipments lifespan and ultimately affect performance.

Under-sizing can result in a system that requires another heating system to be used, instead of the GSHP during periods of cold weather. This is known as an alternative bivalent system and is not very efficient. A top up system would be required to help the system meet its requirements. Whilst it is in fact fairly normal to have what is known as a parallel bivalent system, where two systems work together during periods of peak loads, the Heat pump will work at maximum output providing the base load of the heating, whilst the other system tops up the temperature levels. It is vitally important to know the buildings and its occupant's energy requirements so that the most energy efficient and therefore cost effective system is designed, as generally the use of non renewable supplementary heating should not exceed 5% of the annual energy requirement.

It's not only the sizing of the heat pump that needs to be considered when designing the system. Different ground conditions will have an affect on the performance of the ground coil or borehole system used to collect heat from the ground. It is widely thought that ground source heat pump systems take their heat from geothermal heat however, this only occurs in a few regions of the UK.

The ground collects solar energy and almost all of the ground heating effect comes from the sun, even up to hundreds of meters below ground level. The type of ground ie, sand/gravel, rock, clay have different levels of heat extraction. Even the moisture levels of the ground will have an effect on the performance and therefore the design of the system.

Without a ground condition survey being carried out one could not even say whether or not a coil system is appropriate. If the ground conditions are such that there is let us say, 1m of topsoil over rock then the cost of the installation will vastly increase.

The Best Heat Pump for You

With the prices of utilities spiraling sky high, you would definitely want to check that you have the best heat pump possible. If you choose the right heat pump, you will be able to cut up to thirty percent from your current heating bill, definitely not a sum to be snubbed. What a heat pump does is transfer heat from one source then move it to your home. Hot air inside the house can be moved to another room if wished. Just being able to maintain the temperature of the home makes it a terrific investment for any homeowner.

Which one is right for your home? Pumps come in many sizes and it's important to choose one in the right size for the room. To compute which one you should get, every 400 square feet of space that is lived in needs a ton to heat the area properly. If the house is properly insulated and has double-glazed windows, then a smaller size heater could be used. A good option is to purchase a heater with variable capacity controls. These will allow the system to adjust to required temperatures, keeping heat in living areas and not heating up unused areas. Apart from saving money over the time it is used, these heaters are much quieter than those that require the blowers running at full all the time.

An air source heat pump is double duty: it can heat the home and cool it as needed. The only problems are its noise while operating and it frosting up when in the winter. A ground source heat pump needs to be buried, since it extracts heat from underground. While expensive and hard to install, these are silent and don't have frost problems. Keep your heat pump in good working order by cleaning and periodically replacing the air filter, at the most every two months. Check in between to see if the filters need cleaning. Have it serviced as the manufacturer recommends. Be sure that the area around the pump is kept clear. Any shrubs or vines, snow, even just leaves and grass, can impair the air flow. Air registers should be clear and open as well - make sure that no furniture or covers are in front of them.

The Top 4 Advantages Of Using Heat Pump Inside Offices And Homes

You may wonder why a lot of people are so willing to spend a lot of money buying a heat pump when there are other alternative heat sources available in the market that's way cheaper and popular. If you care about the environment and want to experience convenience at any given time, then you consider the use of a heat pump as your best decision. Heat pump is very effective in moving out heat from one area to another location where lower temperature is normally experienced. It applies the same principles of air-conditioning; the only difference is its effectiveness for both cooling and heating. During cold season, the use of pumps is very popular and preferred by many people and for your advantage of learning the use of this equipment and its details, listed here are the leading advantages of this device.

1. It is very efficient

For every unit of power released by the main pump, the system will then supply around 3 to 5 units of the heat. Heat pump uses a refrigerant that automatically absorbs heat and later on releases the heat at the time it condenses. It has an evaporator that absorbs heat around areas with higher temperature and then releases this heat outside through a condenser. Auxiliary heat source is very important for every pump to produce heat. Among the qualified heat sources are oil, gas and electricity which are abundant at present.

2. It conserves nature

Heat pump's most common energy source is electricity which is often generated using renewable resources such as water and air. And this fact makes the use of the equipment's biodegradable and non-toxic. However, refrigerant system contains harmful content that depletes ozone layer but in general, its effect to nature is very positive.

3. It is easy to use

You don't have to worry about installation and processing, heat pumps are very easy to put up and generate. Upon purchase, you are provided with a user-friendly manual with all the complete instructions. However, if you want to assure proper set-up, you can hire a qualified person to do the job. It can be relatively costly but you are sure to get the worth of your investment as it effectively lowers your power bill over years. There are several forms of pump but they almost suggest the same installation process so you don't have to worry about learning everything from scratch.

4. It is safe and effective

Most heat pumps' compressor is placed outside the home or office and this guarantee you stillness and safety. At times when you don't need the use of the machine, you can always turn it off and get it back when needed. It has a timer that you can set automatically to give you heat after few minutes. A heat pump has no flammable content to produce heat so it will never be the cause of fire. It doesn't need a vent and will always stay reliable for everyday use.
