Could be a few things, the house being cold, a broken temp sensor, disconnect between the sensor and the furnace/pump.
You must have a heat pump with electric auxilliary heat.
I guess it's always running so when you turn it on you don't have to wait for it to heat up because its still warm, unlike when you turn the heat on in a car and cold air comes out and you have to wait for it to heat up. :(
As long as the engine is running, it is normal for the fuel pump to run constantly.
not sure of your application but possibly the pump on the boiler is set to run continuously and the thermostat energises the boiler itself.
Yes, the filter pump must run for the heat pump to effectively heat the pool water. The heat pump relies on water circulation to extract heat from the air and transfer it to the pool water. Without the filter pump operating, water won't flow through the heat exchanger, preventing the heat pump from functioning properly. Therefore, it's essential to have the filter pump running whenever the heat pump is in use.
You will have a flood PLUS your furnace will rust out. Can you hear it run? what happens when you fill the pump with water? Is there electric power to the pump?
No. The heat pump (your outdoor unit) and indoor blower motor will run ok at these power levels, but here is the bad news - if the heat pump can't meet the temperature demand (or it gets below ~ 20F outside), the furnace will attempt to turn on several electric strip heaters (as emergency backup). These strip heaters are rated from ~ 5000W to 20000W, depending on the size of your home. Your generator can't handle that load.
you can leave your furnace fan run continuos, it helps even the heat in the house, it also helps with condensation on windows.
The fan should run for about 3-5 minutes after the furnace shuts off to help distribute the remaining heat throughout the house.
Yes, the outside unit of a heat pump system is supposed to run when the heat is on.
depending on conditions but generally a heat pump will cost you less to run.
the heat pump is cheaper but the pump does not work as well when its below 40 out side thats when you want to run heat strip
