    Are you guys still the Canadian distributor for Hallowell or did you drop it in favour of Zuba?

    I think you are making a poor choice by NOT installing a heat pump. I live in Ontario too, similar sized house with a heat pump and electric furnace. You are very wrong if you think our delivered...

    Am I happy with the product? Yes. Would I do it again today? Only if I knew where the price of oil was going! ;)

    Did I make the right decision last summer when heating oil was $1.25/L? ...

    You need a heat loss calc done on your house to know if the largest Acadia system is even suitable for your big house..... it may not even be an option for you. And then there is the question of...

    It should be noted that this only applies when there is a 2nd stage t-stat call in that temperature range. My Acadia system never gets to a 2nd t-stat call until it is about -8F outside, so I never...

    Maybe you guys should take out annual service contracts with your buddies.... LOL

    I figure it won't cost you anything if you team up in pairs.

    The (forced air) Hallowell Acadia heat pump system will work really well in the Toronto climate, but if you have natural gas available it isn't practical in my opinion.

    That would be a heat demand of 75% of the available total (for the current stage). Or in the case of my simple example, 7.5kW (over the course of 1 hour) of heat being called.

    It's call...

    It works for me (northern climate, very little A/C use). I'm x2 oversized for cooling, but my primary compressor is a Bristol TS that has a 50% 1st stage. I'm more comfortable in the cooling season...

    A contractor worth their wage that uses engineering methods (heat loss calculation and your local weather data) can tell you if it will work for you or not. I can't tell you that sitting here from...

    No. Check the wiring diagrams and the air handler spec sheets. The outdoor unit only has control over the W1 input to air handler. The W2 input is controlled by the tstat.
