Does the unit have a defrost cycle for wintertime heat pump usage?

Yes it does and it goes into defrost mode several times a day. It also has a mode to take the humidity out of the air if needed!

Absolutely.. Heat pumps can not function without a defrost logic in heat mode. ALL Pioneer units have a very sophisticated, self learning fuzzy defrost logic.

Yes it does - I am in North Idaho and it goes into defrost several times a day and then begins heating again.

I've had no frost build up yet, so I don't know about the defrosting mechanism.

Hard to answer as we have had a severe cold spell and I use a heat pump for main heat source. By using this heater my pump would run less often so I guess it's a trade off.

I don't remember. I bought one unit, used it for most or all of one winter, it stopped working, and I switched to using a cheaper one from Walmart that has worked longer.

I don't know. Mine has never shown "defrost". It shows the % humidity. I would suggest to read the manual.

Yes it does, and it works great. I highly recommend it after using it all winter.

It has no auto-defrost. They send a freezer wall scraper with the fridge for you to keep the frost at bay. I hope this helps. BTW it is amazing

Yes it does, it has a switch for the heating season which you can switch for the cooling season

YES..it has a thermostat, it can be set so low that it will only come on at freezing if desired.

Yea, provided that the condenser does not need defrosting. To prevent ice build up on the condenser the fan may continue to run after the humidity level is reached.

It does not have a drain on it like a typical water heater. So the only way to be able to winterized it, in my opinion, would be to disconnect the power and then disconnect the two hoses/pipes and turn the unit upside down to drain. In other words, you'd have to remove it to accomplish this.

No, but that's why I bought it.The other units I had required frequent battery changes. I have this in my garage and it worked all winter (-20 and worse temps)!

In the specifications this unit did not have a thermostat. I use three on my satellite dish since we have a lot of snow and ice and I turn it off an on manually. The units have worked great for two winters.

Never bothered to do anything other than make sure all the water has been drained out of the unit and leave the drain plug out. Sits in the garage over the winter and it easily goes below freezing during the colder months. Never had an issue in over 20+ years.

If you plumb it properly, you can drain it for the winter. I believe there is built in freeze protection on this unit, however, which will activate the burner if it is at freezing point.

HelloThe unit you are inquiring about is an INDOOR unit - but in case you leave the house unattended, and it might be exposed to temperatures below freezing: You should inquire with the manufacturer, Tagaki Toll Free: 888.882.5244My hunch is that if the house is unattended during freeze temperatures, the pipes would have an issue as well. Please call the manufacturer and be consulted for what is best in your specific situation. Regards, Buy and Large Inc

A reverse cycle heat pump does not produce instant heat like a nickel wire heating element.This is a gradual heat that has limitations of operation on days when the outdoor temperatures approach freezing.
