Is it more efficient to use the emergency heat instead of the heat pump when the temperature is in the 30's?
There is still enough heat in the air to run your heat pump when the temp is in the 30,s
When should you use emergency heat?
During an emergency. i.e. when the heat pump is not working. If your heat pump can not keep your house warm, then the auxiliary heating coils (same thing as emergency heat) will come on automatically. If not, then there is a problem with your heating system.
When to use emergency heat setting on a heat pump?
Heat pumps don't work well when its below freezing point temperature's
What does the EM heat mean on your thermostat for your central AC heating unit?
If you have a heat pump A/C unit then you have auxillary heat and emergency heat. The EM stands for emergency heat, which is using only your electric heat strips or gas heat, depending on your system. The auxillary heat uses your compressor inside of your outside unit. Say the house is 60 degrees inside and you set your stat to 70, the temperature difference is so great that if the heat pump alone cannot satisfy, then the auxillary heat would come on to assist the heat pump. Say you were to get a leak in either your condenser or evaporator coils, your heat pump would not work on the regular heat setting on the tstat. In this circumstance you would want to use just the emergency heat until a service tech can evaluate the system.
When should you use em heat on the thermostat?
EM (or emergency heat) can be used if you have a problem with your other heat source such as a heat pump. In most cases, you will not need this but what it does is bi-passes the primary heat source and allows your secondary heat source (normally your furnace) to become the primary.
What is super heat in air conditioning?
you use super to check if the a/c is working at the right temp. You only use super heat on a/c that use pistons. The range is 12 to 20 degrees below the temp on your gauges
Why not just use that energy consumed running the heat pump to run electric heaters inside the house and heat it directly that way?
Heat pump is more efficient. If you use electric heaters, 1 joule of electric energy will produce 1 joule of heat energy. If you use heat pumps, 1 joule of electric energy can pump several joules - perhaps up to 5 or 6, depending on the outside temperature, and the efficiency of the heat pump - of heat, from the outside to the inside.
How do you get your HVAC to pump Heat into the house?
With a normal split system you will have to reclaim refrigerant, install reversing valve, install defrost kit including timer contactor and frost detector. Going to need more control wires to outside and a heat pump thermostat. Going to be a big deal for sure. Go buy a used unit from an installer. If you use gas it's possible your electricla service might need to be increased if you decide to use electric heat as the emergency heat.
Can you use a heat pump just as a air conditioner?
sure why not
Will a 130K BTU heat pump provide adequate heating for a 20x40 pool in New Jersey?
It depends on when you want to swim. If you are looking to extend your swimming season a few months, like from May to September and/or you would like to raise your water temp 10-15 degrees than a 130K heat pump will do the job. The most important thing you can do it to use a solar cover. The heat pump will only raise the temp of the pool approximately .5 to 1 deg an hour and only if the temperature is above 50 degrees or so. So it will take 24 hours to get the pool comfortable and than with a 6-8 hour pool pump run time you should be able to have the water a comfortable 85 degrees or so. Without a solar cover the evaporation will be much higher and you will need to run the heat pump for 10+ hours a day to maintain the desired temperature. If you want to have your pool 90+ degrees regardless of the outside temp and you want it to heat up very quickly, than you definetly want a propane or gas heater. The answer is no. A heat pump requires heat to pump. NJ probably gets a little cold doesn't it? Therefore, no heat to pump. Depending on wind conditions, I would go with a Laars 400LX/LT. HM Louisiana ANSWER: Stay with the Raypak.
Is a programmable thermostat good to use with a heat pump system?
A programmable thermostat works fine with a heat pump. Just remember that a heat pump does not heat as fast as a furnace because of the lower BTU ratings so do not set the thermostat as far back as you normally would. Also make sure to buy a thermostat that has heat pump terminals.
When do you use the em switch on the heat pump thermostat?
If you need to use it, it would suggest that the outside air changeover thermostat on the outdoor unit is either defective or not set correctly. The Em. Ht. switch simply brings on either the strip heat, or in the case of a dual-fuel application, the furnace, to supplement the heat pumps ability when it gets colder outside. A "Balance Point" calculation will determine what temperature this changeover should occurs at. The calculation involves the intersection point of two lines on a graph. One line represents the increasing btuh needs of the building as the outside temp. decreases. Line #2 represents the output of the heat pump relative to outside air temp. (Output decreases as oa temp. decreases) Operation below the intersection of the lines requires the use of supplemental heat. Acurate setting of the changeover tstat assures high efficiency operation down to the Balance Point and saves you money. lc
