    Default Fireplace

    Can a Rumford (masonry) fireplace be counted as a heat source for code/inspection purposes in new construction? If so, how can you determine % of heat efficiency?

    Not quite sure I understand your question.
    Are you considering this fireplace as the main heat source?

    As far as I know that fireplace could be rated around 50% efficient ---- give or take. It's difficult to put exact efficiency numbers to this because efficiency for most wood-burning appliances is determined by the "flue gas loss" method --- the energy wasted up the chimney.
    Glass doors dramatically reduces the effectiveness if not the efficiency since glass blocks over 90% of the radiant heat. Rumfords are good radiant heaters and not very good mass or air heaters.

    Thank you I was wondering how much of an area a 42" Rumford is able to heat (as a back-up option) when electricity is lost...Thanks for your reply.
