Oil-Forced hot air VS ETS room unit

Mark Pennell | Posted in Energy Efficiency and Durability on

Looking for some advice…

I am in Waverley NS, Canada; climate zone 6. 800sf home on one level with a crawlspace (somewhat insulated walls, and dirt floor). House is moderately insulated. I currently spend $1000 on oil (probably more once the heating season ends due to price jump). My oil tank is due to be replaced this year at a cost of $1600. I recently explored the option of ditching my oil furnace all together and getting the Steffes ETS room unit. They quoted me $3140 installed and ready to go (including the timer for my hotwater tank, and TOU meter). On peak electricity cost is 11.6 cents/KWh and off peak is 6.5cents/KWh.

Any input on which way I should go? Ultimately the off peak usage would be nice, and not have to service my furnace and have an oil tank. My house is at the top of a hill with 42 stairs up to it, so I am sure the oil guy wouldn’t mind not delivering oil anymore!

Any help would be greatly appreciated. Please let me know if anymore information is needed.

    These ETS units used to be popular in the UK back in the 60's and 70's as a low-level background heat but they generally needed a boost from a separate on-demand system in the evenings when they tended to be running out of oomph after the previous night's charge. Could work OK alongside a woodstove but unless the technology has vastly improved I wouldn't expect it to achieve the same comfort standard as your oil system when used as a standalone. Have you considered a minisplit heat pump? Could be a good match for an 800 sf home and would probably run about the same installed cost.

    The same question was asked recently, so you may want to have a look:
    (the spam filter won't let me link, but just search this site for "off-peak" and it's the first entry)

    Future energy prices are unknown, but oil is likely to rise faster than electricity.
