There was a C$7k government grant at the time for the heatpump, which roughly matched the tax.
The current Ontario solar grant is weird- it only applies to battery systems without net-metering. They also offered a 10-year interest free loan though so I took that, improves the ROI a little. I think battery systems do make more sense for people who are further sound and using more electricity at the time of year that they are generating it. The solar sales people estimated a 10-year ROI but they had to include a pretty high annual energy cost increase in their calculations (I think 8%/year), I estimated more like 15 years.
I didn't really consider replacement, by all reports the WaterFurnace pump should last 25-30 years and the propane furnace was probably 5 years old so would have lasted about the same. I would think that the WaterFurnace costs a little more to replace, maybe a winter's worth of propane.
Several people told me that ground source heat pumps were too expensive, but years later it still feels like the best investment I've ever made, the gentle heating and cooling is more comfortable too. Anyone with enough space who has to have fuel delivered (propane, oil, etc.) should seriously consider it.
