Multi-sided fireplaces such as "see-throughs", round, triangular, peninsula, or other unconventionally shaped fireplaces are not recommended. They are characteristically temperamental and inefficient and may not draw well unless fitted with exhaust fans.

Back-to-back Rumfords are always more attractive, more versatile, more efficient and less troublesome than any "see-through" or "multi-sided" fireplace.
