What metering device is the most efficient for heat pumps?
Thermostatic Expansion Valve (TXV, TEV). Any high efficient system requires one.
Discharge air temperature of a gas furnace?
gas heating temp range from 120-140 degrees, electric heat strip is 110-125 degrees, heat pumps are 95-115 degrees
What is more efficient heat pumps with or without gas back-up?
with gas back up . a heat pump alone ,will not be able to extract heat efficiently when it reaches it's economic balance point in its region of operation.
Will a heat pump work well in the Northeast?
It is not the preferred method of heat due to climate in the NE US. Air source heat pumps are ineffective below 35* or so.
What are heat pumps used for?
A heat pump is a central air conditioner that uses a reversing switch to operate in reverse; the way the air conditioner works in the summer. If you went to the big fan unit (condenser) outside your house during the summer, you would notice, it blows hot air from the fan . Heat pumps are used to produce heat for residential housing, economically, by absorbing temperate winter air, and using it to heat your house. Heat pumps can usually maintain heat in your house down to about 20 degrees Fahrenheit, until you would need to use another source to heat your house. Heat pumps are mostly used in the Southern parts of the United States, where the winters are mild, Heat pumps can be economically used in other parts of the United States where average temperature during the winter may not go below the 20 degrees, disused earlier, and the break-over price for fuel cost using the main furnace. Usually, propane gas, verses running the electricity for the heat pump is more economical. To find out if a heat pump would work for your situation. Contact a qualified hvac contractor to perform an energy survey of your residence.
What heat are pumps?
A better way to heat and cool your home - but it may be expensive in the git go. Heat pumps have a problem heating with temperatures below 35 degrees. They can't provide heat if it is below 35 degrees outside. Pipes are laid under ground to use the 55 degree amibent heat there and the heater with 55 degree coolant, the heat is extacted by the heatpump to warm your house. They can also work in the reverse to cool homes. Acting similar to a refrigerator, heat pumps can draw heat from the home and transfer it into the ground and tamp into the cooler ground temperature.

Should you use the heat pump in the winter?
Heat pumps are much more efficient than they used to be. For example a 3 ton 13 SEER heat pump today can generate 22,000 btu's of heat even at 32 degrees. Compare that with heat pumps 15 - 20 years ago where you were lucky to get 10,000 btu's at the same temperature. So yes, run your heat pump all winter.
Do heat pumps for swimming pools work well in new york?
In a word YES.Modern quality heat pumps can extract heat from the air even when the temperature is below freezing.
What metering device is the most efficient for heat pumps?
Thermostatic Expansion Valve (TXV, TEV). Any high efficient system requires one.
What is the function of ground source heat pumps?
Ground Source Heat Pumps or GSHPs are underground central heating cooling systems. Because they use the surrounding earth to dissipate heat in the summer or absorb it in the winter, they are consider energy efficient and good for the environment.
Discharge air temperature of a gas furnace?
gas heating temp range from 120-140 degrees, electric heat strip is 110-125 degrees, heat pumps are 95-115 degrees
What is the worst rated heat pumps?
what are the worst rated heat pumps
Does heat move in or out of water cooled below 0 degrees?
Out
What is more efficient heat pumps with or without gas back-up?
with gas back up . a heat pump alone ,will not be able to extract heat efficiently when it reaches it's economic balance point in its region of operation.
What should supply air temp be for heat pump heating?
With heat pumps supply air temp will vary with outdoor temp. The colder it gets outside the less efficient the heat pump will be (colder supply air).
Understanding The Geothermal Heat Pump?
Conventional heat pumps heat homes and buildings by extracting heat from the outside air. In summer months, heat pumps function as air conditioners by reversing the process. Unfortunately, heat pumps are trying to provide heat when the air is coldest outside and to cool when the air is hottest. Thus, in very cold and very hot weather, conventional heat pumps do not operate efficiently.The Geothermal Heat PumpGeothermal heat pumps offer another solution to heat and cool homes and commercial buildings. Instead of exchanging heat with air, these heat pumps exchange heat with the ground or a source of water. This gives geothermal heat pumps a significant efficiency advantage over conventional heat pumps because the ground and water sources are more thermally inert than air. What this means is that the ground below the frost line and bodies of water do not change temperature much no matter what the season. So geothermal heat pumps do not have to work as hard to heat in the winter and cool in the summer as conventional heat pumps do. Consequently, they use significantly less electricity than conventional heat pumps and have less need for auxiliary heating sources. There are two types of geothermal heat pumps. The closed system uses a mix of water and antifreeze that flows through pipes buried in the ground or submerged in a large body of water such as a pond or lake. The open loop system pumps water from a well, pond, or lake through the heat pump and then pumps the water back to the source or to a drainage ditch.Factors to ConsiderGeothermal heat pumps are more efficient than conventional heat pumps, but that efficiency advantage varies greatly. A consumer may see as little as a 20% gain over his current energy source, or he may see in excess of 60% gains in efficiency. Factors such as the local geology, availability of a water source, the type of geothermal heat pump installed, and the cost of the type of energy currently used impact the efficiency gains. Geothermal heat pumps also cost twice as much or more than conventional heat pumps to purchase and install. However, they cost less to maintain and usually have a longer lifespan than conventional heat pumps. Home and business owners should do significant research and seek expert assistance before determining which type of heat pump is right for them.
