The Stockton Milner wood burning and multi fuel fire fits a 16" or 22" fireplace without the chair brick needing to be removed. This means it can be easily fitted into an existing chimney without needing any extra building work. The Milner fire is cheaper to install because of this. It is also more efficient than an open fire. The Stockton Milner gives you greater control of the fire combustion, more heat for your money and therefore lower fuel costs.
