13. Will heat pump water heater provide enough hot water for baths showers & domestic hot water?
With the correct design and equipment, all domestic hot water requirements
would be provided by the air source or ground source heat pump throughout the
year. Heat pumps produce water at a lower temperature than boiler systems.
Instead of water that may be scalding water produced is hot enough for all normal
domestic requirements. You will notice that you do not have to add as much cold
water to your baths and showers. The aim is to save money and energy with either
an air source or ground source system. There is no point in taking water to
temperatures that can't be used anyway (above 55°C).
12. What is advantages of heat pump water heater?
1.Typically draws approximately 1/3 to 1/4 of the electricity of a standard resistance heater for the same amount of heating, reducing utility bills. This typical efficiency compares to 70-95% for a fossil fuel-powered boiler.
2.Few moving parts, reducing maintenance requirements. However, it should be ensured that the outdoor heat exchanger and fan is kept free from leaves and debris.
3.As an electric system, no flammable or potentially asphyxiating fuel is used at the point of heating, reducing the potential danger to users, and removing the need to obtain gas or fuel supplies (except for electricity).
4.May be used to heat air, or water.
5.The same system may be used for air conditioning in summer, as well as a heating system in winter.
6.lower running costs - the compressor being the thing that uses most power
11. How is the heat transferred into a building?
The earth, water and air have the ability to absorb and store heat from the sun. For example, in the case of a ground source system this heat is extracted from the earth using a ground loop. In the case of an air source heat pump this harnesses solar energy found in the outdoor air. With this system there is no need for digging or drilling and installation is very quick and simple. It is ideal for urban sites where there is very little ground space. The ground loop is a continuous closed loop of special pipe buried around the building. A mixture of water and food grade anti-freeze is circulated through the buried pipes where it absorbs heat from the surrounding earth. The ground loop is connected to a heat pump inside a building that takes heat out of the circulating mixture and transfers it into a heating circuit and hot water tank.
10. What are Geothermal heat pumps ?
I know what you are thinking: "What are Geothermal Heat pumps?" Well, let's use a simple illustration: Take a piping hot cup of coffee and let it sit for 15-20 minutes. Taste it. What has happened? We would say that it 'cooled off.' But what really happened? Actually, what happened was that the heat in the hot cup of coffee 'transferred' to the cup and to the surrounding air. But suppose we reverse that: what if we devise a machine that would take a cold cup of coffee, extract the heat from the air surrounding it, and pump it into the coffee. What would happen? The coffee would get hot. This is exactly what geothermal heat pumps do: it "pumps" the heat - it moves it in a certain way. So, if geothermal heat pumps are to work, they must have a source of heat: either the surrounding air or --- in the case of geothermal heat pumps, the source of the heat is the heat from the ground or soil (we sometimes call them 'ground source heat pumps'). So geothermal heat pumps use the ground for heat - 'geothermal'. other types of heat pumps (called 'air source' heat pumps) take heat from the air around the unit.
Geothermal heat pumps can also be used to cool a building - just reverse the process. It will now act like a refrigerator: geothermal heat pumps take heat from inside the building and move it to the ground outside (and it is cool even in the summer). Again, the air source heat pump must move the hot air from the building to the hot air outside, and again the air source heat pump must work harder. So, in hot weather cool, or cold, geothermal heat pumps can usually operate more efficiently - and that means savings for you! Another great option for those using geothermal heat pumps is to use it for heating hot water. Geothermal heat pumps can be installed with an add-on device called a 'desuperheater' - this device will partially heat your water. But here's the ingenious part: in summertime, when your air conditioner is running (geothermal heat pumps can double as air conditioners), the desuperheater will use some of the extra heat taken out by the air conditioning process to heat your hot water! So, in the summertime, your water will be heated for free! In wintertime, part of the heating power of geothermal heat pumps is used to heat the water. If, in your home, your geothermal heat pumps will be operating most of the time (especially to cool things off in the summer) you can save lots of $$ in heating your water. For many today, GHP's (Geothermal Heat Pumps) are the only way to go!
9. Our church installed a geothermal heat pump. The contractor told me they are also the most efficient, comfortable way to air-condition and heat homes. Would one be a good choice for my 2,000 sq. ft. home?
To give you an idea of how efficient they are, an older, but still working, central air conditioner may have an efficiency rating of 8. The most efficient geothermal heat pumps have efficiencies as high as 27. If it now costs you $300 per month to cool your house, your monthly cooling electric bills would be cut to only about $90. There would also be winter savings.
The cost of installing a typical 3-ton (36,000 Btu) geothermal heat pump will cost several thousand dollars more than installing a gas furnace and a central air conditioner. The geothermal heat pump often will pay back the higher initial cost in about eight years or less depending on local utility rates. Geothermal heat pumps typically have a life of 20 years or more.
There are two designs of geothermal heat pumps. One type uses a polyethylene pipe ground loop either in a horizontal trench or vertical holes in your yard. A water/antifreeze solution runs through the pipes which are connected to the unit inside your home. No outdoor unit, with a noisy condenser fan/coils, is required. The indoor compressor makes little sound.
The other design (called DX) uses small copper tubes buried in the ground and the refrigerant flows through them. With this direct heat exchanging with the ground, less tubing is needed. This is often ideal for small lots.

7. I hear people install a heat pump instead of a furnace and air conditioner even in cold climates. I can't afford a geothermal one. Would a standard air heat pump work well and what are newest designs?
Heat pumps are becoming a more common alternative to central air conditioners because they can also heat your house. The cost of electricity for heating and cooling a house, although it gradually increases as do most prices over time, is much less volatile than natural gas, oil or propane. You may also get up to a tax credit for installing a heat pump.
A geothermal heat pump is one of the most energy efficient heating and cooling systems for any climate. Even though it provides a good payback on the investment, particularly in very hot or cold climates, the initial installation costs are considerably higher than for air-source models.
An air-source heat pump is basically a central air conditioner with a few extra parts. During the summer, it draws heat from the indoor air and, through a refrigeration cycle identical to an air conditioner, expels the heat outdoors. The cooling efficiency is rated by its SEER (seasonal energy efficiency ratio).
During the winter, a reversing valve inside the outdoor condenser unit switches position. This reverses the flow of the refrigerant so it begins to draw heat from the outdoor air and transfers it so an indoor coil. Heating efficiency is rated by HSPF (heating seasonal performance factor).

3. How Does a Heat Pump Work?
At the heart of a modern heat pump is a refrigeration system. Paradoxically, the refrigeration cycle is an efficient provider of heat as well as cooling and the basics of its operation are quite easily understood.
There are two principle locations in the transfer of heat; the place where heat is absorbed, (the source), and where it is rejected, (the destination). The compressor in the refrigeration system also produces waste heat, and a significant proportion of this can be recovered, thereby reducing running costs and the ultimate release of CO2.
The mechanical refrigeration cycle consists of an arrangement of heat exchangers; one that absorbs heat, the other that rejects it. All but the largest industrial systems are hermetically sealed and pressurised, thereby reducing noise, space and heat losses. This means that the compressor and the motor that drives it are encased in a welded shell.
This heat absorbed is transported through a sealed system of pipes by a fluid, the refrigerant, circulated by a compressor. The refrigerant is a fluid that has a low boiling point. A metering device to control the flow of refrigerant completes the arrangement and it is all connected by pipes. As the refrigerant works under pressure, the whole system is sealed for life.
In order to absorb and release the heat into and from the refrigerant, we exploit the ability of the refrigerant fluid to boil from a liquid to a vapour and then to condense back into a liquid. This is a continual process while the compressor is running and circulating the refrigerant.
For all volatile substances, there is a known relationship between its pressure and its boiling point; by controlling these in the refrigerant we can achieve cooling and heating in the same machine at the same time.
High pressure liquid refrigerant is fed through the metering device into the evaporator heat exchanger where it evaporates into a vapour by absorption of heat from the heat source (air, water, ground, other) passing through the heat exchanger.
The relatively cool return vapour is drawn back to the compressor. The compressor and the electric motor that drive it are constructed in a fully sealed hermetic shell. The cooled return vapour from the evaporator is passed over the compressor motor windings within the heat pump, thus cooling the windings of the motor.
Much of the energy absorbed by the electric motor driving the compressor is absorbed into the refrigerant.
The combined heat from the source, plus much of the waste energy from the electric motor is then compressed to a high temperature vapour and enters the condenser heat exchanger where it is cooled and condensed into a high pressure liquid ready to begin the cycle again.
The heat released during the process of condensing the refrigerant to a liquid is rejected via the heat exchanger directly into air or transferred to water to heat the building. The air or water temperature at this point could be 43oC to 60oC, depending on the design of the system.
Although some systems are configured for heating only, reverse cycle heat pumps use an electrically operated reversing valve with four pipe connections to change the direction of refrigerant flow within the system so that the system is able to deliver both heating and cooling as desired.
Many commercial systems are capable of cooling as well as heating, with fully automatic control enabling the user to receive year-round operational benefits.
2. Compared with traditional water heater, what is the uniqueness of air source heat pump water heater?
First, convenient installation: vno limit of installing condition for air source heat pump water heater;
Second, safe operation: since no direct contact between water and electroniccomponents, no danger in leaking of electricity;
Third, saving energy and power: the electricity consumption of air source heatpump water heater is equal to 1/4 power consumption of common electric water heater;1/3 gas water heater;1/2 solar water heater.
1. What is heat pump technology?
Heat flows naturally from a higher to a lower temperature. Heat pumps, however, are able to force the heat flow in the other direction, using a relatively small amount of high quality drive energy (electricity, fuel, or high-temperature waste heat). Thus heat pumps can transfer heat from natural heat sources in the surroundings, such as the air, ground or water, or from man-made heat sources such as industrial or domestic waste, to a building or an industrial application. Heat pumps can also be used for cooling. Heat is then transferred in the opposite direction, from the application that is cooled, to surroundings at a higher temperature. Sometimes the excess heat from cooling is used to meet a simultaneous heat demand.
In order to transport heat from a heat source to a heat sink, external energy is needed to drive the heat pump. Theoretically, the total heat delivered by the heat pump is equal to the heat extracted from the heat source, plus the amount of drive energy supplied. Electrically-driven heat pumps for heating buildings typically supply 100 kWh of heat with just 20-40 kWh of electricity. Many industrial heat pumps can achieve even higher performance, and supply the same amount of heat with only 3-10 kWh of electricity.
