I recently had a Mitsubishi hyper heat installed to replace my natural gas furnace. The air handler is connected to the ducts so it was an easy transition. I live in Chicago so I also had 10kW resistive heat strips installed as a backup. This winter they never needed to come on, and I was able to keep the house at 70 degrees F even when we hit around 0 degrees F outside. I haven't crunched all the numbers but so far my electricity bill has gone up by about as much as my gas bill has gone down, so there really isn't much savings there which is too bad. I mainly did this though for the environmental benefits, as I want to slowly phase out all natural gas in my home. Next step will be to replace my gas range with an induction cooker, and the last will be a heat pump water heater.
