See-Thru fireplaces heat output

See-Thru fireplaces heat output

See-Thru fireplaces heat output

(OP)
I am doing a design on a house with a 38MBH input Twilight See-thru fireplace to the outside (http://www.fireplaces.com/downloads/brochures/HNG_TWILIGHTII_BRO.PDF).

My question is how much of that load should I figure is going through to the inside and how much is going to the outside? Will adding a fan shift the balance of where the heat is going? I am up in Canada design temperature of -10*F

Thanks.

RE: See-Thru fireplaces heat output

Fire places transfer heat by radiation for the most part and not convection. If you add a fan, convection will go way up depending upon fan/heat exchanger configuration.

Get a cut of the fan option from the purveyor.

A well-designed  fan/fireplace  system will be 40-50% efficient if you can control combustion air.
