summer time AC can help warming up water using heat dumped outside?

[@randytorboli]

How efficient would a heat pump that is a package unit be versus a split system version

[@juancbarahona7544]

I considering heat pump, but I do not like the fact that the system apparently uses a back up (furnace) . Can the heat pump work on their own.

[@FATL0L0]

So ,, will a heat pump work for me hear in Southern Arizona where we see 118 average in the summer??

[@x14inchdubsx30]

Yes

Here is the basic function of a heat pump warming.... the compressor "compresses air" thus, compressing air heats the air. For example, run ANY compressor and after a few moments, put your hand next to the tank, walla, heat. Listening to someone tells you that there is heat in air regardless of how cold the air is, is a razzle dazzle speak, without telling you the truth of using a compressor and the basics of what happens when air is compressed. PERIOD.

Well that was a pretty lame explanation. Does he even know what is really going on?

HOW are you extracting HEAT out of 40 deg F cold air to bring it inside the home...??

[@TheDime4life]

You Tube the refrigerant inside the copper lines runs the opposite direction in the winter so instead removing the heat outside it picks up heat and when it reaches the coil inside above the furnace the air blowing across it absorbs the heat in the refrigerant. And refrigerant is very very sensitive to temperature so it can it can pick up a good bit of heat especially when it’s 40 outside

TheDime4life sorry... That was confusing as hell... I'm usually very good at technical stuff but that there just did not make any sense to me...

A heat pump does not produce energy. It pumps it from one side to the other. The outside air is full og energy, even below freezing. Otherwise you would have zero °kelvin in the air. The heatpump takes huge amounts of cold outside air, and compress it to less amounts of warmer refrigerant which is being pumped to the coils inside the house.

Anders Skjoldager-Gregersen heat pump being the compressor outside ?? It takes cold air from outside somehow and compresses it to warmer air and pushes it to the inside coils ..?? Im still comfused how the compressor pulls cold air in when its a sealed unit ...

think of it this way, cold does not exist. "cold" as we describe it is just nothing more than absence of heat. the less heat the cooler we feel, that is all. there is always heat. what the system does is pump refrigerant. during the warm months, the outdoor unit (condenser) is used to release heat outdoors. the outdoor unit also houses the compressor, and other components. Your furnace is indoors, weather it be gas, electric, or heat pump with duel fuel or electric, where the air handler indoors is just using gas for heat, thats typical, as well as provides cooling in the summer, or with a heat pump, it will house the coil, a fan, electric strip heat possibly, or components for gas heat. in a duel fuel set up, it uses the heat pump until the temp drops down to around 15 to 20 outside, once it reaches that temp, it locks out the compressor and uses the secondary heat source. weather its gas heat, or just electric strip heat. during heat pump operation, it uses the refrigerant in reverse. instead of the refrigerant absorbing the thermal energy indoors and expelling it outdoors, it absorbs the thermal energy outdoors and releases the thermal energy indoors to heat your home. when the outdoor temps are around 15 to 20 degrees, it is not efficient to grab the thermal energy outdoors anymore so it locks out the heat pump system and switches to a secondary heat source. newer systems can do even better with inverter technology. the compressor speed can be controlled by demand and stage up and down to efficiently control cooling and heating. using less energy, which saves money on your electric bill. so lets say in the summer its like 75 outside, and your house is set to be 73 degrees, and it went up to 74, the stat will time out, adjust depending on deadband settings. and will bring the cooling on, well instead of it being the compressor 100% full speed to cool the home it will only ramp up a bit, running the compressor slowly, which will slowly bring down the temp in your home, depending on the load of how long it takes to properly cool, if it takes longer, it will ramp the compressor speed up higher to continue to bring the space down to temperature. and then shut off thus saving energy. thats one other reason why you dont want an over sized system. While it sounds like a good idea, you dont want that at all. you dont want to cool your house down to fast, if you do so, you have for one have a lot of start and stops on the system, which is hard on the compressor and will shorten is life, as well as you will not remove enough moisture from the space and then you may start to feel cold and clammy, you want a properly sized system to remove enough moisture from the space, normally around 30 to 60% humidity. but also you dont want to heat your house to fast, you dont want to get to much dry air either, thats why a lot of times a humidifier is installed to humidify the air to keep the space comfortable. so basicly a HVAC system is nothing more than a liquid, vapor process. the changing state in the system is what absorbs thermal energy (heat) and moves it around. weather that is outdoors during cooling season or indoors (if its a heat pump)
