Which type of heating system to install in my home Heat pump or gas furnace and ac unit?
That will depend on the cost (and availability) of gas in your area, when compared to electric costs. It will also depend on the climate. At very cold temperatures (below 40 F) the heat transfer element of an air/Freon heat pump does not deliver heat, and the less efficient electric heat kicks in. In a climate that has long periods of below-freezing temps, a gas furnace may be more economical to operate.

Can you install a heat exchanger on an existing heat pump that will allow you to heat your pool while cooling your home?
Yes, you can, but you will probably have to design and fabricate it yourself as I am not aware of any commercially available kits to help you accomplish this task. What you are asking for is not unreasonable. It makes perfect sense to use the heat that is extracted from your house to heat the pool w…ater rather than just exhaust it to the outside air. However, only recently have the major HVAC manufacturers started thinking about their systems in an integrated fashion, i.e. figuring out ways to move heat from the places its not wanted to the places where its needed ALL WITHIN ONE SYSTEM. At this point in time, there is no real standardization of heat pump components that would allow you to simply and easily take the heat from the heat pump and transfer it to another heat exchanger to warm the pool water because there are so many different types of heat pumps that have been manufactured over the past 20-40 years. Thus, even if someone did develop a kit of this sort, it would still require some kind of custom-built piping and control mechanism to interface with all of the different manufacturers and models of heat pumps that are out there in the world. Hope this helps ... from Jalex137: It's an interesting idea, but I wonder if it's practical. It seems to me that during the season that you would be cooling your house, you wouldn't need to be heating the pool. from Uncledunc: the reason you heat the pool water in the summer is the difference in the temperature between the air and pool water. On a 75 degree day, your pool water at 67-68 degrees fees fine. But if tomorrow the afternoon temperature shoots up to 90 you turn blue and FREEZE. Living in So-Cal tells one all he needs to know about heating the pool (often with solar covers during the day, plus the heater) to enjoy swimming on hot summer (and Fall) days. Keeping the air to water temperature within about 10 degrees (max) is ideal, from my experience with 4 in-ground pools. My father-in-law attempted the AC heats pool water trick back in the late '60's but the contraption he came up with had no controls - just a big water tank with SS piping for the Freon gas. Later he attempted to upgrade the idea with a switching mechanism to route the refrigerant to the normal condensing coils when the pool water was already hot enough. Bottom line - the hardest part is sizing the heat exchanger to the thermal load of the house (cu. ft. / not sq. ft.) and the gallonage of the pool for your typical summer ambient temperature (and nighttime temperature swings) in your local. There is no "1-size-fits-all" answer. And it takes some decent thermodynamic engineering to get it right. IMHO, the concept is feasible, but the trick is to over-size the heat exchanger and then TRY to locate a suppler of a high pressure switch to shut off the pool's heat exchanger. Otherwise you run the risk of have your pool turn into a sauna/spa... which some folks might actually prefer! But, if nothing else, in northern climates you'll get a longer swimming season without turning on the heater. Hope this adds to the discussion. - Uncledunc (MORE)
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 soft…ware 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!

Answer . This is not a job for the home fix-er-upper type. There are special tools required, and special training and Federal/EPA training and testing required for refrigerant recovering and recycling. Assuming, then, that you had all of this covered, you would: make the unit safe, disable an…d lockout the electrical power supply, Pull the refrigerant out of the system and store for later recycling, verify there is no pressure in the system, cut the pipes with a tube cutter leading to the compressor. Remove the power leads to the compressor. Remove the compressor. Mount the new compressor, Fit up new copper pipes and solder them in with a nitrogen purge and limited flux. Connect the power leads. Put a deep vacuum on the system and check for leaks. Charge the system with the correct number of pounds/ounces of refrigerant. Start the system and test run, checking the system pressures with guages to verify proper operation. Put all the panels back on, (with ALL the screws). (MORE)
We have central heat and air. Does the furnace blower unit power on for the AC system too or is there a separate blower?
Answer . There should be only one blower to move the air. The unit will have a coil for cooling and a heat exchanger.
An AC unit isn't supposed to heat! If you mean a heat pump, then you may have a relay switch problem. Or maybe, your thermostat is in the cooling mode. Contact a repairman.
The energy source is the same as for heating anything. Gas,Electricity, Burning any fossil fuel. in a boiler (furnace) with water running in heat exchanging coils or manifolds. When heat is needed a pump circulates the hot water through the radiators and back to the furness.
Kerosene and home heating oil can be mixed in a oil furnace.Kerosene is thinner than heating oil. Mixed together will make thefurnace burn cleaner.
\nNot unless your unit has air flow drop sensors that could damage the pumps. If you installed a new filter and the furnace then quit maybe you didn't properly replace the door. There may be a switch attached to the door or filter. Look fer it!
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 coole…r 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.

In cgs units, one erg is 1 g cm 2 s â2 , equal to 1.0Ã10 â7 J. The imperial /U.S. units for both energy and work include the foot-pound force (1.3558 J), the British thermal unit (Btu) which has various values in the region of 1055 J, and the horsepower-hour (2.6845 MJ). The energy… unit used for everyday electricity , particularly for utility bills, is the kilowatt-hour (kWh), and one kWh is equivalent to 3.6Ã10 6 J (3600 kJ or 3.6 MJ). Electricity usage is often given in units of kilowatt-hours per year (kWh/yr). This is actually a measurement of average power consumption, i.e., the average rate at which energy is transferred. The calorie equals the amount of thermal energy necessary to raise the temperature of one gram of water by 1 Celsius degree, at a pressure of 1 atm. For thermochemistry a calorie of 4.184 J is used, but other calories have also been defined, such as the International Steam Table calorie of 4.1868 J. Food energy is measured in large calories or kilocalories, often simply written capitalized as "Calories" (= 10 3 calories). In physics and chemistry, it is still common to measure energy on the atomic scale in the non-SI, but convenient, units electronvolts (eV). The Hartree (the atomic unit of energy) is commonly used in calculations. Historically Rydberg units have been used. In spectroscopy and related fields it is common to measure energy levels in units of reciprocal centimetres. These units (cm â1 ) are strictly speaking not energy units but units proportional to energies, with hc being the proportionality constant. (MORE)

I don't know of to many cons about owning a heat pump.. Pro's:. lower heating bills. acts as an air conditioner in the summer. Below 30*F outdoor temp they are worthless.

What size unit does the home require? Do not just replace what is there without having him do a heat load calculation on your home. What is the efficiency rating (SEER) of the unit he proposes to sell you? Higher is better, but also more $ and more things to go wrong as you get into 2 speed fans and… compressors. I personally would go with the lowest SEER currently available which is 13 for the last reason I mentioned. You are probably replacing a unit with a SEER rating of < 10 so you will see an improvement in energy usage with a 13 anyway. What type of refrigerant does it use? R-22 which is what you probably have now, will be beginning to be phased out in the next few years and will become very expensive should you develop a troublesome leak. If it uses R-410A the piping will need to be replaced with new, regardless of what anyone may try & tell you and this will initially cost you extra $ but you should make the switch. What if any parts are proprietary to the manufacturer of the unit? Which means you will only be able to buy those parts from a dealer of that brand , as opposed to regularly available parts from a local refrigeration supplier. Some parts will almost certainly be proprietary such as control circuit boards etc and for that reason go with one of the well known brands. Lastly, who will be doing the install? The reason for this is many larger Co`s have many young techs just out of school, I`m not knocking them but it should be a consideration. PS, these Co`s are often the ones who employ salesmen and that salesman`s pay is built into your price quote. Therefore a reputable, local, smaller, contractor even a one man band who employs a helper is worth a look for a new install. The final thing you should ask of course is price and compare what you are getting vs price from all of the bids you get. Please understand, my background is in Commercial/Industrial HVAC service not residential installs and for that reason what I`ve said here should only be considerations in response to your question, not hard and fast rules of thumb used to generalize anybody or the product they may put out.

How can i find how much it cost to run a air heat pump in central Illinois compared to a gas furnace?
Find out what you pay per kWh, then determine the wattage used per hour of run time of the heat pump. Then multiply the two for cost of runtime per hour. Do the same with your cost per therm (100 cubic feet of natural gas). Determine the input rate of the furnace in btu per hour (100,000 btu input w…ould equal 1 therm used per hour of runtime). Multiply the two and you have your cost per hour of runtime. For example: at $ 1.00 per therm cost and an input rate of 80,000 btu or .8 therms, you would have a cost of $.80 per hour of runtime with natural gas. With a cost of 11 cents per kWh and a system that uses 15 amps, 15 amps x 230 volts = 3450 watts or 3.45kW, multiply that times .11 cents and your cost per hour of runtime is .38 cents. Lastly don`t forget to add in the wattage per hour of the electric strip heater you will need to go with the heat pump. Don`t worry about the power consumption of the indoor fan because you will need that to operate either one. Regardless of how the cost works out for you, I personally would not entertain using a heat pump in your climate. (MORE)
I am assuming that by asking about a "heating thermostat" for a "furnace" we are not talking about air conditioning/heating units or about electric heating units (baseboard, wall-mounted, etc.). If the furnace already has a thermostat installed then it is just a matter of replacing the existing the…rmostat with a new one. Heat-only thermostats can be obtained from home centers such as Lowes or Home Depot. They should be specified to work on 24-volt circuits, unlike those designed for 110/220 volt AC electric heaters. Replacement is simply a matter of removing the thermostat cover, detatching it from the wall, and disconnecting the two wires from the old unit. Connect the wires to the new thermostat and mount it to the wall in place of the old one. Be aware that some thermostats must be adjusted level to work properly - read the enclosed literature that comes with the new unit. If this is a new or replacement furnace that has never had a thermostat connected then there are several additional considerations. You will need to identify a location for the thermostat. This location should be on an interior wall, out of any drafts, and in a location such as a hallway which is an "average" of surrounding rooms. You will have to run 2-conductor thermostat wire (available at home centers) from the furnace to the thermostat. Connections to the thermostat are as outlined above. The connections at the furnace end depend on the type of furnace - passive hot air, forced hot air, passive hot water, circulator-driven hot water, steam, etc. These variations are beyond the scope of this general question.

Could be lots of things. If you have a standing pilot light, one that stays on all the time, the thermocouple may be bad. A thermocouple is a small rod that sits in the flame of the pilot light. It then runs to the gas valve. This produces a small amount of electricity that keeps the valve open to l…et the gas in. If the pilot light goes out it shuts the valve so the house doesn't blow up. Easy enough to replace. If the pilot light is still on and the furnace will not light, it has to be the thermocouple. Check fuses at the furnace and in the panel. Newer gas furnaces have a circuit board in them that can go bad. There are a dozen things that could keep it from working, it is just a process of elination. (MORE)
That depends on what the cost for each particular fuel is in your area and the btu yield of each. Example: 1 gallon # 2 fuel oil yields 140,000 btu and 1 kW=3413 btu.
