Question heat pump

Hi just wondering how many amps my heat pump draws when it kicks in and why it seems to blow cold air at times. We are brand new owners and on a pretty sharp learning curve at the moment so please bear with me if I ask a million (and a half) questions

According to the specs the HP draws 15.4a/1675w.

These heat pumps are not the most efficient I've seen, we use ours when outside temps are over 40-45, any lower temps will make the HP useless, it just blows cool air. When I know the low temps will be below 45 I use the furnace.

We love our heat pump here along the shore in CT. With the weather shifting from summer to fall we use our heat pump to keep the unit at 67. We are hovering in the forties at night and so far for the past three years it has kept it just right. Remember you have to move the thermostat only at four degree increments or else it will switch to propane heat.

I've been using mine every night and morning. a couple of times it blew cold early morning when outside temps dropped to 30 degrees. I had to switch over to LP.

We have 2 - and it takes a bit in the morning to get it going warm. They don't have a way to start and heat up before the fan kicks on like a furnace does, so you get the initial cold.

Couple of hints -

If the temperature is more than about 15 degrees from the thermostat setting when you turn it on, the furnace will over-ride the heat pump until the temperature gets within about 5 degrees of the thermostat setting.

If you have 2 heat pumps - don't get caught with one on AC and one on heat, or they run like crazy fighting each other in the same duct, and heat wins. I thought I could manage administratively last year, but I continued to repeat the error all throughout this year. We have LR AC on during the day. At night with it cools down, we turn on BR heat pump, but forget to turn of the LR AC. At some point the temp setting collide and they both start running opposite functions.

On the meter we have installed it seems there is a 3 to 4 amp draw regularly between the light voltage appliances running as the heat pump turns on I'll notice it goes to 18 amps. It seems to drop an amp or two after it's been running for a while. We showed up at the rig the other morning, the rig was 58 degrees I set the heat pump to 70. Yes the furnace kicked on with the heat pump but we were up to temperature in a very short time. Then the furnace shut down and the heat pump has no trouble keeping up with the temperature.

Little trick on the thermostat, set the temperature 2or3degrees above the room temperature wait for the heat pump to start then set to desired temperature,heat pump will keep running.

Great tip Ian! I'll have to give it a try.

Quick question? Are they real heat pumps or just 1500watt heating elements? There's a difference.
