Give me the model numbers on the heat pump and the coil, I would expect its a really poor match.

Lux Thermostat 500


The Lux 500 Thermostat is an affordable programmable thermostat that gives you a very easy way to customize your heating and cooling temperatures to your schedule. The programming of this thermostat is easily the simplest that I have found in a programmable t-stat.

The Lux 500 series thermostats are a great economical way to reduce energy and utility expenses by raising or lowering your temperature settings a the times you set. The installation is so easy that most any DIY’er can install this thermostat. It has an easy to read display and the rotary dial makes the programming very user friendly.

A few of the other great features of this unit are, a keyboard lockout, and an air filter reminder.

This thermostat can be used on any 24v AC or 750mV single stage conventional heating/cooling system. Single stage heat pumps without auxiliary heat will also work with this thermostat.

Here is a summary of the features of this thermostat

Underfloor Radiant Heating works great with a Geothermal Heat Pump


Radiant floor heating has been the standard for comfort and efficiency for many years. The feeling of having a warm floor under your bare feet is priceless. Rolling on the floor while playing with your children or grandchildren is great when it is cold outside and the floor is pleasantly warm.

Geothermal Heat Pumps usually are associated with hot air heating and air conditioning systems. If you live in a climate that very seldom needs air conditioning, then you need to concentrate more on the heating. There is a super way to use geothermal technology to give you very efficient and comfortable heating. Underfloor radiant heating can very easily be incorporated with a geothermal heat pump to give you the best of both comfort and efficiency.

Here are some thing’s that you do have to consider before deciding on a system like this.
You will need to drill a few wells to extract the heat from the ground.
Piping must be installed in the wells correctly for the system to work properly.
You will need a heat pump designed for hot water heating.
You can not use a heat pump that is designed for hot air use and convert it for radiant heating.
The radiant heat design must be designed to use water temperatures that are cooler than that of many radiant heat systems.
The maximum temperature design should be 130 degrees F.
To get this kind of design to work correctly for you, you will need to use good quality heat plates and insulated under the heat plates.
By following these guidelines I have designed a number of radiant heating systems that have proven to heat houses very comfortably at temperatures well below zero.

If you decide on installing this type of system make sure that your installer knows exactly what they are doing. This type of system requires many things to be done exactly right, so that the water flows will allow the system to work correctly. The piping on the well side is extremely critical so that it uses all the wells equally. On the house side the piped using a primary/secondary piping scheme. Pumps and pipe sizes need to be able to give you very high flow rates so that the temperature drop is kept to ten degrees or less. When working with these low temperatures the piping and pumping becomes so much more critical.

By using these principles you can combine two very great heating types and can have a very good heating system that will perform very well for many years. The main drawback with this type of system is that you do not have the ability to get much cooling from this system. This is probably the only drawback of this type of system. It would be wondeful if there was a geothermal unit that was heating only. The elimination of the reversing valve would be a great cost savings and a plus overall. This system is best suited for cooler climates that require little or no air conditioning.

Just had a new house built and its all electric. Has a Tempstar heat pump. There are two model numbers involved: FSM4X4800A1 (attic unit) and N4H348AKE100 (outside unit). This is a 4 ton unit and I...


It's entry level with regard to efficiency. At the same time, it's not a bad piece of equipment. Made by Carrier ICP. I've installed many of these. I suspect since you had your house foamed, it's probably not costing you a heck of alot to heat or cool- so it would be hard to justify changing it just to add seer points. It would be difficult to get a pay-back on your investment. I say roll with it and enjoy your new home!

Where do I set thermostat when temp is 10 degrees outside?


Setting a thermostat has nothing to do with outdoor temperature, but more to do with what is a comfortable setting for you and your utility bill.

A common misconception associated with thermostats is that a furnace works harder than normal to warm the space back to a comfortable temperature after the thermostat has been set back, resulting in little or no savings. This misconception has been dispelled by years of research and numerous studies. The fuel required to reheat a building to a comfortable temperature is roughly equal to the fuel saved as the building drops to the lower temperature. You save fuel between the time that the temperature stabilizes at the lower level and the next time heat is needed. So, the longer your house remains at the lower temperature, the more energy you save.

Another misconception is that the higher you raise a thermostat, the more heat the furnace will put out, or that the house will warm up faster if the thermostat is raised higher. Furnaces put out the same amount of heat no matter how high the thermostat is set; the variable is how long it must stay on to reach the set temperature.

In the winter, significant savings can be obtained by manually or automatically reducing your thermostat's temperature setting for as little as four hours per day. These savings can be attributed to a building's heat loss in the winter, which depends greatly on the difference between the inside and outside temperatures. For example, if you set the temperature back on your thermostat for an entire night, your energy savings will be substantial. By turning your thermostat back 10 to 15 degrees for 8 hours, you can save about 5 to 15 percent a year on your heating bill -- a savings of as much as 1 percent for each degree if the setback period is eight hours long.
Hope this helps..........

My heat willnot come on all i here is humm in the unit under the house and nothing inthe outside unit it is a "Googman-ARUF02400A1"


Ok, If you don't have a heat pump, you should not be hearing anything from the outside unit. I assume you have electric heat. I feel strongly that you have a bad fan motor capacitor. This is what sends a jolt of power to start the fan motor. Good luck and have a great day.

Goodman heats but defrosts turns on before desired temp.


Yes. The defrost cycle of a heat pump is actually turning on your airconditioning to heat up the condenser to thaw it out. During this cycle your electric strip heaters "should" be adequate enough to compensate for the a/c being on. At about 30 - 34 degrees outdoor temp there is not enough heat in the air to to adequately heat your home with the heat pump only. Some technitions will use an outdoor thermostat to turn off the heat pump when it is under 34 degrees outside. If you are to cold when its under 34 degrees intall more electric strip heaters.. But if you do this your electric bill may go up significantly.
Welcome to the wonderful world of electric heat pumps (lol).
Good luck.

Not enought heat


I have the same heater and it works great in my bedroom (with a door). the room is about 12 x 14. For my living room and dining area I use 2 or 3 oscillating, ceramic, fan forced heaters spaced out.

As you say, logically...since heat rises, the heat comes off the top. Only 3 things that I can think of would make that heater not work: First, a factory defect (it doesn't heat period). Second, if you have it a room that is too large for that size heater. Third, if the room has no doors (such as a living room).

If you have a draft it can work to your advantage. By placing the heater in line with the draft it will actually accelerate the heat exchange process and distribute the heat faster for you.
