    So I have forced air heat with an oil furnace currently...I was checking into getting central A/C installed and quickly learned that most people go with a heat pump since this gives you A/C in the summer and heats your home in the cooler months. Basically, you add the heat pump onto the existing forced air furnace setup and your oil furnace only kicks in when it goes below like -12C outside, so a tank of oil lasts you like 3years which sounds good to me LOL.

    The tradeoff though is your elec bill goes up to run the heat pump. Anyone have any experience with these in terms of how much of a jump in the elec bill I can expect from heating the house with the heat pump? I'm fine with a hit in the summer for cooling when it's running in A/C mode, but I am trying to sort out how much extra its going to cost for heat in the winter versus the money spent on oil.

    In my experience dealing with customers who have these, their bills still seem to be high. Then again I only deal with the ones calling in wondering why their bills are so high.

    place im at right now has ETS' and the money I save on the off hours billing I have is rediculous. My power bill in the summer is usually about $100 for a 2-3 month period. In the heart of winter its around 500-600 for the same period.

    I do think its shitty on NSP's part to only offer the special billing to people who have ETS though. they should be trying to award anybody who is trying to be greener and use less energy via a heat pump or whatever else.

    Hmmm interesting but the skeptic in me keeps saying of course NS Power is going to suggest an electrically powered heating appliance like a heat pump can both heat AND cool my home for "about the same annual cost as other heat-only systems" LOL

    I'd like to hear from anyone who did the heat pump add-on to an oil furnace system to see how much their elec bill went up over the cooler months vs the oil savings. I'm not doing any kind of ETS setup, it will just be the add-on heat pump with my existing oil furnace.

    do yourself a favor...tomorrow call NSP and ask to speak to an energy adviser. No they don't have first hand experience, but they can take the square footage of your home and give you an estimate.

    We have a new build with a heat pump only system. I over sized by 1/2 tonne and it works really well; The electric backup doesn't kick in until about -18C or so, and even then it's only on for a few minutes at a time. Since we've been in the house for over a year I was able to go on the "budget plan", which is now $180/month for ~2500sqft 2 story house. Feb/March bills are, of course, the highest at around $400-$450 for the two months. That includes all my heat/AC/hot water which I think is awesome. If we had to do it again I might go with a combo ETS/Heat Pump system or maybe an ETS with a min-split heat pump. We could save a bundle is NSPower would allow us on the time-of-day plan.

    id like to bump this thread and see if there are anymore people with experience with this type of system. we have forced hot air at the moment and am interested in the benefits/drawbacks of an add on system

    you could call us and we could give you some basic info, but if your looking for first hand experience we can't do much...

    I'm interested in this also. Currently heating with forced air and my oil usage is very reasonable. 2000 sq ft house with about 1000 unfinished and I'm averaging about $1000 a year on oil for heat and hot water. Electricity usage is about $70 per month as well.

    the first month or so of using the heat pump will be the most expensive from what i've seen as it's using the most power to circulate everything around the house.

    For what its worth......ive installed maybe 1000 to 2000 heat pumps around HRM.

    ETS is the way to go if youre looking to save. When a regular heat pump needs to use its electric back up, they all hog the power. But you do get what you pay for. If you buy a cheap system, you get a higher electric bill and a bunch of problems when you need the system the most. Spend the extra couple grand, get a quality system.

    i have a sanyo energy star rated 12000 btu unit in my up stairs. haven't got first power bill yet but i haven't used my baseboard heat yet this year. My upstairs area is only 1000 sq foot and is quite open. it keeps the bedrooms at 18 and the living room / kitchen at about 22. We use programamble thermostats and set them just below around 17, 16 in bedrooms. Heat pump has night setback setting at 11pm it goes back a degree a hour untill it reaches 18 degrees. Works flawlessly i love it Quiet and will make heat up untill -18 I guess so Will not likely see it that cold here mabye one or 2 days a year.

    Cost about 3500 installed

    Wow, I'd be really interested to know what brand of heat pump that you have which can go down to -18!!! Or is that only an estimate?
    If it's for sure, please post what your setup is :)

    What makes and models would you consider to be "Quality"? I'm thinking about a Carrier model, but that's just what was suggested by a local retailer. I have a nice carrier t-stat that I'd like to keep, and it seems to just be a plug and reprogram to get this unit added into my system. It's pricier, but I know the name from selling window AC units some years ago. Some friends have purchased York with success (only 1-2 years ago though).

    Also, would you recommend having an outdoor thermometer (and maybe hygrometer?) sensor installed as well, or is that automatically included.

    Are you talking ductless split heat pump? Or a full furnace?

    I dont find much use for the outdoor thermometer, its just an accessory. They are included with some packages but its really up to the tech installing if he feels like installing it at the time.

    Full furnace I think. There are definitely ducts in the house.

    Hmm....so...how does the system determine if the heat pump should be used instead of the heating coil (or otherwise) without an outdoor thermometer?

    The system works together as a whole to create heating or cooling. Theres no strictly heating coil or ac coil. A reversing valve reverses the flow of refrigerant to determine weather the inside or outside coil is a hot coil or cold coil (hot coil being inside for heating, vice verca for cooling). Whatever your temperature balance points on your digital thermostat are set to will determine when the heating kicks in or cooling kicks in.

    Kind of hard to explain right now, as i am pretty damn tired

    My aunt and uncle were running on electric heat up until they installed heat pumps (I think 2?) and have seen solid savings year over year.

    On another note, my gf's parents have a heat pump installed and it has been nothing but a nightmare, no one seems to be able to fix it.

    IMHO...it's nice to offer you knowledge, but saying these things as your first post doesn't help for establishing credibility...if you come to post again, lmk and I'll delete this comment ;)
