What size aux heat do you need for heat pump?
An average 3 ton heat pump on a 1200 to 1500 sq ft home in California will typically have a 1500Watt (1.5KW) to 5000 Watt (5 KW) auxiliary heat kit installed. This is not just for emergency heat in case of compressor failure or too low of an ambient temperature to operate a heat pump efficiently, but also to temper the air going into the home while a heat pump defrosts. Since the defrost mode is the AC mode with the outside fan motor of the air going indoors will be refrigerated, this is why the heat strip wil be used to temper the air to avoid having to bring the room back up to where it was when defrost began.

How do you size wire for a 20kw aug heater for a heat pump?
Answer . Using the formula: Amps = Watts/Volts look up the wire size needed in the national electric code book for the amperage of the device. This formula only works for single phase current. If you are using 3 phase, look in the book. In general, 15 Amps or less: 14 Ga Copper wire. 20 Amps or less 12 Ga. 30 Amps or less 10 Ga. Anything more than 30 amps, look it up in the book.
What size heat pump do you need for 2632 suare foot single story home with a 700 square foot room in the basement in northeastern Pennsylvania?

What size heat pump do you need for a 2200 sq ft house in east Tennessee?
You need 1 ton of cooling for every 400 square feet. This means 5 1/2 tons, but you would be best off with a 5 ton unit. a slightly undersized unit will run for longer periods of time compared to the 5 1/2 ton unit, but it will be a more efficient system. The less starts and stops will also reduce the wear and tear on your compressor, which will result in a longer compressor lifespan.
What size heat pump system is needed for an 1100 square foot home?
Answer . I just did extensive research before having a new heat pump put on my house. consumer reports and various books at the library said square footage is not the best or the most acccurate way to figure sizing the unit. there is a manual J that a.c.companys should use and also computer software one can purchase online to size it yourself. everything i read stressed that most a/c companys install units larger than needed and indeed all the companys that gave me estimates simply asked my square footage and took my word about it and then told me the tonnage i needed based on my numbers and eyeballing the existing unit. they all came up with a minimum size of 4 and up to a five ton unit! my research told me that the max size i really needed was 2.5 to 3 tons. long story short my house is 1200 sq ft minimum and i bought a 3 ton unit with a seer rating of 13[ the higher the seer rating the more efficient, but with the higher rating is more complicated repairs more often according to consumer reports]. my old unit was plenty big enough for my house and when they put the 3 ton on it dwarfed my old unit. point being that even at 3 tons i probably bought bigger than needed. back to your question. buy no bigger than 3 ton and a 2 1/2 ton will probably do. get one with a seer factor of 13 no more no less. buy a good brand such as my lennox and lastly dont let them bullcrap you into anything bigger or extended warrantys. get the longest warrantees and estimates from at least 4 to 5 companys.and then make them give you their best price and dont be afraid to play one against another. my original estimate started at almost 7 grand and the one i chose was 5 grand even and came with with a programmable thermostat. dont pay more than 5 grand & shoot for less. dont budge when they try to steer you and they will try!!! let me know how you come out!
Can you heat a spa with an electric heat pump?
Is this heat pump approved by your local codes or that of NSPF for use in or around swimming pools? I think not. Not a good idea to mix water and electricity. . Yes you could, if you live in a very hot climate... heat pumps would only be able to heat water to spa temperature if the weather was very hot all the time. It works the reverse of an air conditioner, but relys on outside air to convert cold to hot water.

What is a heat pump?
A heat pump is a heating system that applies the principle of refrigeraation to heating homes. These principles are: 1. when a gas is quickly compressed, it's temperature rises; 2. when a gas is allowed to expand suddenly it's temperature fallls; 3. when a liquid evaporates, it absorbs heat; and 4. when a gas condenses it releases heat.
Does your heat pump need freon to heat your house?

What size heat pump should be used in south west Virginia for heating approx 2200 sq ft?
The largest household unit is 5 tons, which I install in California for your square footage. Depending on your construction two units splitting the load may be warranted. If you are building a new home it is better to overkill with insulation than spending extra energy money to heat a shell.
What size heat pump is needed for a 1600 square foot duplex?
Contrary to popular belief, the required BTU output, or "tonnage", cannot be calculated based on square footage. Many factors go into determining the required BTU output to compensate for your home's heat loss/gain. A properly trained HVAC technician has the ability to calculate the required heat load for your home based on where you live, the materials your home is built with, the "r" value of your insulation, window type/size/quality/quantity, and even which direction each exterior wall faces. Many "old school" technicians say 500sqft per ton, but with today's strict building codes and better insulation, this rule of thumb no longer applies. In most cases, the old rule will cause you to oversize your system, resulting in big problems down the road, i.e., high humidity, mold, mildew, etc.
How can Geothermal heat pumps heat a home?
While temperatures above ground change a lot from day to day and season to season, temperatures in the upper 10 feet of the Earth's surface hold nearly constant between 50 and 60 degrees Fahrenheit. For most areas, this means that soil temperatures are usually warmer than the air in winter and cooler than the air in summer. Geothermal heat pumps use the Earth's constant temperatures to heat and cool buildings. They transfer heat from the ground (or water) into buildings in winter and reverse the process in the summer.
Heat pump vs non heat pump?

Geothermal heat pumps can heat homes by?
By using the ground as the source for heat, much like an airsource heat pump uses air to remove the heat from the air on a cold day a geothermal system using the more consistent earth as the source for pulling heat out of the ground to heat your home in the winter and cool your home in the summer. The earths more consistent temperatures allow the system to work better than an air source system and in general the Geothermal system is more effiencent than any other type of heating used in homes.
How Does Heating From A Heat Pump Work?
The heart of the heat pump is the Copeland scroll compressor. The compressor continuously pumps the ozone safe refrigerant from the outside coils to the inside coils. The refrigerant carries the heat with it to be released inside the house. Then the warm air is circulated throughout the home by the furnace fan. In the summer the flow of the refrigerant reverses and the house is cooled in the same way. The scroll compressors are extremely reliable and virtually trouble free. Copeland is the largest manufacturer of heat pump compressors in the United States. Our Goodman heat pumps are built to last with reliable Copeland scroll compressors. Scroll compressors are very durable because they have fewer parts than the older reciprocating compressors and are also simpler in construction. Instead of pistons and valves which the older compressors had, the scroll compressor has a scroll that orbits to compress the refrigerant.

If installed properly by a competent contractor they are likely no better or worse than any other brand unless you buy a low end builders grade model. Like anything else you get what you pay for.
What is the life expectancy of a heat pump?
It depends on how much your heat pump is used, checked, serviced, and how well it is maintained. ( Always have your HVAC systems regularly maintained to increase life expectancy !) The usage of a heat pump varies greatly depending on where you live. Other factors can include if it is an air-source or ground-source. So, a very general ball park life expectancy of a heat pump is anywhere from 15-25 years for the inside components.

Why does a heat pump need an external source of energy to heat a house?
Heat pumps use a compressor to make the working fluid condense at ahigher temperature.The compressor needs input energy.
What is a heat pump unit?
A heat pump is one part, of a two part heating and cooling system and can be used as the primary heating unit in mild winter locations. They can also be used to supplement other heating systems where the temperatures are sub-freezing for longer time periods. Heat pumps also are used in summer for cooling. Basically, the way the system works in cooling mode is the same as most any other AC system. When winter comes it essentially runs the system in reverse to produce heat instead of cooling. The advantage is that it is very cheap to run. The biggest two disadvantages are the compressor has to run during both seasons, causing wear... and ... after you get to about 26 degrees F., the heat pump needs auxiliary heat (gas or electric coil) to warm your house. For most warmer climates they are the best choice. Speak with an HVAC professional to determine your region's best heating option.
How much energy is needed for a heat pump defrost cycle?
About 10% during the outdoor temperature from about 40 degrees to 20 degrees. Not a lot beyond those temperatures that make frost on the outdoor coil...assuming you have a unit with a good electronic defrost control.
How do you size heat pump for in ground pool?
Decide how warm you want your pool water to be. Most people prefer a temperature in the high 70s or low 80s (Fahrenheit), but your individual taste may vary. . Step 2. Determine the average temperature during the coldest month you wish to use the pool. You can usually do a quick estimation based on your own experiences, but if you want formal numbers, check the National Weather Service for average temperatures in your area. . Step 3. Subtract the ideal temperature of the pool water from the average outside monthly temperature. The result is the number of degrees Fahrenheit your heater will need to warm the pool in order to make it comfortable. . Step 4. Calculate the surface area of your pool. If you have a rectangular pool, this is easy: simply multiply the pool's length by its width. If your pool has a more unusual shape, apply the formula provided at PoolBright.com (see Resources, below). . Step 5. Multiply the surface area from Step 4 by the required elevation in pool temperature from Step 3. Then multiply the results by 11. That figure is the number of British Thermal Units per hour (btu/hr.) your heater will need to produce in order to adequately heat your pool.
Does heat pumps need Freon to blow heat out?
Yes, the heat pump (in the heating mode) is like an air conditioner in reverse. It cools the outside air and heats the room air. Of course, you need Freon to do this heat-transfer process.

How does a heat pump use freon to heat?
A valve is used to reverse the flow of freon. In the heat mode, the high or hot side gas is pumped to the indoor unit, The low or cold side is pumped to the outdoor unit. The valve is reversed for the cool mode. Pumping cool gas to the indoor unit and hot gas to the outdoor unit.
How does the Heat pump produsce heat in the winter?
Unlike traditional heating systems like furnaces or boilers that burn fuel, heat pumps don't actually PRODUCE heat - instead, they use a special type of refrigerant to move heat from the outside to the inside. You can think of it like an air conditioner in reverse: With an air conditioner, the refrigerant moves from the compressor, where it is compressed into a hot liquid. The liquid releases its heat outside, aided by the fans on the compressor. Now cooled, it moves into the evaporator, where is absorbs heat around it and turns back into a gas. The evaporator coil gets extremely cold, and when air blows over it and into your house, the air is cooled. A heat pump works the exact same way, but opposite - they pull heat from the outside air and blow it into your home. Heat pumps are effective even when it FEELS cold outside - in fact, many can pull heat from the air even when the temperature is lower than 30 o F!
What size heat pump is needed for a 180 square meter house?
You need to first work out your heat load for the house which depends on lots of factors. (Insulation, exposure, window area etc.). Since most heat pumps give an efficiency ratio of no more than 4 to 1. This means for every kilowatt of electricity you burn driving the pump you will get 4 kilowatts of heat. So if you think you can heat your house with 12 kilowatts of electric fires then you heat it with a 4 or 5 kilowatt heat pump. The trick with heat pumps is to find a good source of low grade heat that is still there in the winter. Ground coils, bore holes , streams, even pools, are all better than air to air systems because when you need most heat the air outside is coldest.
Why is there an electric heating coil in a heat pump?
Heat pumps don't work well when the temperature outside drops below 40 degrees Fahrenheit. The way a heat pump works is by absorbing heat from outside and moving inside using the refrigerant. Much like an air conditioner absorbs the heat from inside of your home and moves it out. Therefore the colder it is outside the less heat a heat pump can produce. The reason they install electric heat strips is to ensure that when the temperature outside gets below 40 you will still have enough heat available to heat the property.
What size heat pump to heat 18000 gallon pool?
The size of the heat pump is not the true question in this case. Most, if not all produce enough btu to heat a pool that size. The true question on a heatpump is how long. The larger the btu rating of the heatpump... the faster the pool water will reach desired temp. Heatpumps should only be used to maintain heat in a pool. The most inefficient way to use a heatpump is to try and raise the pool temp a large temperature differintial at any given time. This type of "on demand" heat will create a scenario where the heatpump runs continuous at its highest capacity until desired temp is obtained, and the highest setting of "heat" on a heatpump is its most inefficient usage of energy. This type of energy usage is only an acceptable practice early in the spring when attempting to raise the pool temp for the first time that anual season. The recommended use for a heatpump is to set the swim temp and allow the heat pump to maintain the temp to extend the swim-ability of the pool one to two months early in the spring and late in the fall. Maintaining the pool temp is a much more efficient use of energy than trying to use a heatpump to create "on demand" heat.
How heat pump used to heat the building?
Imagine a window AC unit installed backwards, rejecting heat indoors while air conditioning the world, this is a heat pumps heat mode. As the unit is air conditioning in the cool outdoors eventually the outdoor coil will ice up requiring a defrost cycle, defrost is the AC mode except the outdoor fans off to assist with the defrosting. A defrost cycle is time and temperature initiated, time or temperature terminated.
What size Teck cable is required for a mini split heat pump that is 15 amps?
Two conductor and three conductor #12 Teck cables are rated at 20 amps. This size is one over from the 15 amp rated wire. This is because on motor loads the conductor size has to be 125% of the motors full load amps. Since all that was stated is 15 amps it is better to err on the larger size wire.
