Vanier is a different job from the suburbs. Older, denser, and frequently no ductwork at all, which changes the design rather than the outcome.
A lot of Vanier housing predates central forced air. If your home heats with boilers and radiators, or with electric baseboards, there is no duct system for a central heat pump to use. That is not a barrier - it points to a ductless multi-zone system, with individual indoor heads serving the rooms that need them. It also means the rooms can be controlled separately, which in a semi or a converted double is usually an improvement rather than a compromise.
Baseboards deliver one unit of heat per unit of electricity. A cold-climate heat pump delivers roughly two to three across an Ottawa season. If you heat with baseboards in Vanier, the running-cost case is not close, the incentive is $1,250 per ton rather than the roughly $500 per ton a gas conversion gets, and you get cooling in a part of the city that gets genuinely hot in July.
Plenty of Vanier homes are on a 100 amp service, and a few years ago that meant a service upgrade before anything else could happen. Not any more. A load manager lets the heat pump share the panel with everything else in the house, and it is what we fit on most installs like this. An upgrade is only on the table for a large home with big extra loads. We do the load calculation and sort the load manager as part of the job; the one thing we need from you is your last year of electricity usage from Hydro Ottawa or Hydro One, which you can pull from your online account.
We work throughout Vanier, Overbrook, New Edinburgh, Manor Park and the surrounding inner-east neighbourhoods.
Sizing decides everything else, including whether your electrical service can carry the system. Our heat pump design tool runs a load calculation for your address, and the panel sizing tool will tell you where your service stands.
