in THE MAIN WALL
Looking at a small cabin with a 13000 btu radiant heat load. It is located on a rocky hill and propane supply is an issue. I was trying to possibly use an electric water heater for a heat source. Rates in the area are 8.5cents /kwh. As a precaution I will fill system with a glycol mixture. How do I convert these numbers in to a dollar amount for useage?

    Easy Math...

    13,000 divded by 3413 (btu/s per kilowatt) = 3.81

    3.81 kilowatts per hour times .085 = $0.32 cents per hour.

    Time 24 hours = 7.72/day, and so on and so forth...

    easy math

    when you put it that way. Thanks for your response. Whats your feeling about this approach? The overall cost and design will be very quick and easy and it makes me feel I may be missing something. Thanks agin.

    If it's got the output, and electric is a viable source in your area, the only downside is the additional water volume you are glycol'ing.

    maybe look at one of the electric boilers? they are pretty cheap too. Argo, Electro and Seisco all make nice units... bigger amperage draw though.

    So long as you don't have a misplaced zero some place...

    How many square feet is the dwelling?

    Is that kwh cost with taxes etc etc, thats cheap if it is. that small a place why not use cheap electric space heaters. Less cost, nothing to really worry about.

    usage

    Hmmm Usage duration, and frequency come to mind for a radiant cabin.

    The only thing about the radiant it takes a while to get her up to temp.

    Maybe a pellet stove, or as suggested electric baseboard. Or if it needs new windows ME can hook you up with some electric radiant windows. Less mass to get going than a radiant floor.

    Thinking like a Watt head again...

    The COVE heaters offer inexpensive radiant heat, out of the way..

    Electric Radiant

    You could also install electric radiant as long as it has the capacity to meet your heat load. Some only offer floor warming so make sure you read the details.

    Direct solar radiant

    Why not direct solar radiant. with electric baseboard or wood heat back up?

    feet. Customer asked about radiant so just trying to give him the possibility. Future plans may include solar for pool heating and we could join the two systems in the future. thanks.
