Default Air to Air Heat Pumps

We have one with an electric furnace.

Should we adjust the temp setting at night time or just leave the temp control in one position ? Seem to be different views from searching on the net and speaking to other people. Unfortunately not many people seem to have one where I work so difficult to ask. A neighbour adjusts his temp control down at night, but the engineer we spoke to and internet articles seem to suggest keeping the temp fixed at the comfortable level.

Confused here ! Anyone who has one and has experience with it ( and heat costs ), I would appreciate your thoughts.

The question is, to adjust or not adjust I suppose ?

No personal experience with them Paul but my sister-in-law and her husband have one out on Vancouver Island.

They lower their thermostat at night, the only time the electric furnace kicks in is first thing in the morning if the heat pump can't provide enough to warm the house up again. This only happens maybe once or twice in the heating season.

Cheers
Steve

Yeah, that might be different over here in NB. Trying to use it in the most effecient way i.e. using the heat pump instead of the element in the furnace is obviously better but having it lower temp at night nothing would come on so saving more BUT heating the house up in the morning may need the electric element if the heat pump can't cope therefore negating the saving.

My head hurts.

I wonder if it would help if you dropped the temp by say only two or three degrees Celsius, and in the morning raised it one degree at about 6:00 am and the rest at 7:00 am or 8:00 am so it wasn't trying to warm it all up at once.

Just a thought.

That's what we're thinking Steve. Still would be nice if anyone has any longer term experience of them than someone who has just arrived and says 'yes we have one'.

Paul

We had a heat pump when we lived on Fredericton. We lowered the temperature by a couple of degrees at night. Make sure you keep the day and night temps within 3 or 4 degrees of each other, as heat pump systems tend to loose their heat very quickly. Our house was 3500 sq ft and I believe the largest electricity bill was for $300 (for 1 month)
