Heat moves toward cold, but also rises. In this case, it radiates outward.
Turn the heat on then go to the airhandler, if the larger of the 2 copper pipes (insulated one) gets hot it is a heat pump. If it remains at room temperature your airhandler has an electric heater installed in it.
If the dash lights go on and off and the heat won't turn off and electrical noise is coming from the heater, there could be a short in the wiring on a 1998 Blazer. This is also possible if the ground wire for these items is not longer attached.
No, and this is a very good energy saving practice.
Not sure how it works, but it seems that you need to raise the humidistat to make the heat go on. Just raising the thermostat doesn't turn on the heater. Type your answer here...
It's not a bad idea to turn off the water heater especially if it is electric. It will consume power the whole time you are gone to keep the water hot and wastes a lot of electricity.
it maybe your heater core is going out recommend replacing it and go from there
If this is about a car: the heater in a car is basically another radiator, but this one sitting inside the car. When you turn the heater on you draw heat from the engine and into the car. If you aren't running the car hard enough the temperature in the engine will drop.
Go with the gas heat.
No there is not. Whats the problem no heat ?? If so try this, reverse the heater hoses on the heater core and then go drive the truck and see if you get heat.
An electric heat pump needs heat available to pump. If it is 30 degrees outside, heating a spa to 102 or so, may be impossible unless the heater has some type of alternative heat source. A properly sized, gas fired heater can take care of a larger range of heating needs. A combination heat pump and natural gas heater, probably with a controller, really makes the issue more difficult, expensive, and would require a lot of study for efficient, cost effective operation. Bottom line: In really mild climates a heat pump might do the job. In cooler climates the gas heater rules. And where a wide range of temperatures and high heat demand is wanted by the customer, a gas heater is the only way to go. A backup heat pump may take years to payout. HM Louisiana
Why does your ac and heater fan turn off and on
No, because devices (light bulb, heater, TV set, and so on...) in our home are connected in parallel.
