Will an emergency generator with a 6500W to 8500W Max capacity power a heat pump rated at 197V to 253 max volts?
Answer . No. The heat pump (your outdoor unit) and indoor blower motor will run ok at these power levels, but here is the bad news - if the heat pump can't meet the temperature demand (or it gets below ~ 20F outside), the furnace will attempt to turn on several electric strip heaters (as emergenc…y backup). These strip heaters are rated from ~ 5000W to 20000W, depending on the size of your home. Your generator can't handle that load.. (MORE)

Valve You probably are looking at a faulty heater valve. It controls the flow of water into the heater core and will corrode and become useless after time. Stuck open and you'd probably never notice but stuck closed and no heat. It will be located on the top heater hose and you may be able to work …it open. im gonna have to disagree about the heater valve i had the exact same problem and it turned out to be my water pump was locked up Mine is doing the same thing, only mine is a 98. I've looked at the top of the heater hose and don't see anything that could be a heater valve. Can you give more details? (MORE)
The normal current carrying capacity is 6 amps per square millimeter without any cooling with forced cooling the number can be as high as 30 amps per square millimeter and for a motor application this means 5 times the energy density so a typical 1 or 2 KW/Kg energy density is now 5 to 10 KW/Kg in a… continuous operation and peak values can be 10 times for a min or 20 times for a few seconds. The limiting factor is the thermal effects and how you deal with them the more efficient the heat removal the higher the allowed level of current. (MORE)
Heat capacity is The ratio of the heat energy absorbed by a substance to the substance's increase in temperature. The quantity of heat required to raise a unit mass of homogeneous material one unit in temperature along a specified path, provided that during the process no phase or chemical change…s occur, is known as the heat capacity of the material. Moreover, the path is so restricted that the only work effects are those necessarily done on the surroundings to cause the change to conform to the specified path. The path is usually at either constant pressure or constant volume. In accordance with the first law of thermodynamics, heat capacity at constant pressure Cp is equal to the rate of change of enthalpy with temperature at constant pressure (?H/?T)p. Heat capacity at constant volume Cv is the rate of change of internal energy with temperature at constant volume (?U/?T)v. It is usually expressed as calories per degree in terms of the amount of the material being considered. Heat capacity and its temperature variation depend on differences in energy levels for atoms. Heat capacities are measured with a calorimeter and are important as a means of determining the entropies of materials. (MORE)

Answer . The Twenty-Second Amendment limits Presidential terms of office; the relevant portion reads as follows: . No person shall be elected to the office of the President more than twice, and no person who has held the office of President, or acted as President, for more than two years of a… term to which some other person was elected President shall be elected to the office of the President more than once.. So the answer is yes; a person may serve two and a half terms as President, provided they entered the office by completing the someone else's term. The interpretation of this amendment (and its interaction with the Twelfth Amendment, which sets qualifications for the Vice Presidency) is unclear in a situation where a twice-elected President later seeks election to the Vice Presidency; also, it is unclear if the Speaker of the House or other officer could succeed to the Presidency if they had twice been elected President. However, such situations seem unlikely to arise. (MORE)
Small bridges may weigh about that much, or maybe a house full with a lot of stuff. Of course, you can't pick it up and see, because 2.5 tons is a lot, but just roughly estimating is good enough.
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.

Heat capacity is the amount of heat something can take before it changes temperature by a degree. If we use water as an example, it is said to have a high heat capacity as you need to heat it a lot before it changes temperature at all. Latent means not yet existing. Latent heat is therefore refer…ring to the amount of heat it would take something for it to change state. Water is said to have a high latent heat of vaporisation. That means that it takes a lot of heat to vaporise water. While heat capacity talks about how much heat something can take, latent heat talks about how much heat something requires to cause a change. Similar concepts but they have slight differences. (MORE)

You need to check the compressor sticker or plate. If faded or unreadable try the installation paperwork/instructions. Typically you can search by the model number online to find it.
heat capicity is the amount of heat you have to apply to a substance to raise it's temperature. This is Measured in Joules per kilogram per degree celcius (or more accurately degrees kelvin). (J/kg/K). For example you have to apply a lot more heat to water than the same weight of copper to increase …it's temperature so water has a higher heat capicity. It also takes a lot longer for water to cool down than copper this is also due to water's higher heat capacity. (MORE)

A Heat pump is a air conditioning/heating system that utilizes a reversing valve in the refrigerant circut that reverses the flow, and brings the heat in side the home from outdoors
Your 19 year old carrier 3 ton heat pump with anywhere from 7-10 seer needs replacing can you use a 13 seer 3 ton carrier heat pump with a 7-10 seer air handler?

Yes, depending on how long the lines are. The unit should have a sticker showing the unit's charge, then you have to figure the lines and the coils in the furnace.
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. (MORE)
Calculate or calibrate?. Calculate - apart from reference to tables for the pump, impossible. Calibrate - get a stop-watch and a very big bucket, switch on and stand back..

Cooling capacity of 30,000 btu per hour. That is the nominal total of both sensible and latent heat.
There are 2000 pounds in one ton (short ton). Therefore, 2.5 tons is equal to 2.5 x 2000 = 5000 pounds. Subtracting 4900 pounds from this gives 5000 - 4900 = 100 pounds. Therefore, 2.5 tons is heavier by 100 pounds.

My 3 ton geo unit uses a 30 amp breaker. That is probably more than adequate because it also is for the vertical loop pumps in the ground. The back-up heat strips however, use a 60 amp breaker (on my system.) I'm not sure but I would say yours probably needs that too. Good luck!
Heat Capacity and Specific Heat Capacity The amount of of temperature change, when thermal energy is added to the particles is another property that particles in different materials have. Different materials will increase or decrease their average energy depending on how much thermal energy is pro…vided. Heat Capacity is the amount of thermal energy that warms or cools an object by 1 o C (it depends on the mass and the type of particle the object is made of).

No when It comes to heating and cooling the rule is a little smaller is better. All heating and air conditioning units are a little under sized to prevent short cycling which wastes energy far more than long run cycles. Short cycling also adds to equipment stress and can actually shorten the life of… a system as all the parts are design to run for long periods of time and not for starting and stopping in short periods. Liken it to your car and MPG, you get much better MPG on the highway then through the city because you are not wasting energy building up to speed. (MORE)

A standard ton of refrigeration is 12,000 BTU/h (3517 W). There for a 2 ton unit is a 24,000 BTU/h unit and a 3 ton unit is a 36,000 BTU/h unit.
Cost may vary depends on the house size, accessibility, the amount of work involved in duct reworking, disconnecting/connecting gas electricity.

That could have many different variables such as ceiling hights heat loss to windows . But under normal conditions a two tone unit should be sufficent.
TR is tons of refrigeration. When ice was used for refrigeration, a ton was the amount of cooling you got from letting one (short) ton of ice at 32 degrees F melt in a 24 hour period. It is now 12,000 BTU's per hour. Since we are talking Army units of measure, note also that in terms of heating 12,0…00 BTU's would not be 12 MB (with M the Roman numeral for thousand) but .012 MB (with M standing for a million.)

2.5 as a fraction in lowest terms = 2 1 /2 2.5 * 10 /10 = 5 /2 or 2 1 /2 in fraction in lowest term
No because the air temperature would either make the unit over do or in some cases it would make the unit not put out enough.
None. 2.5 inches is a measure of distance, it is a linear measure and has absolutely no area associated with it.
Conduct a test as follows: 1. Place the suction side or suction hose of the pump into a fluid. 2.
