Choosing a fire - Where to start?

There are many factors to consider when installing a wood fire and ensuring you select the correct size and model for your home and heating requirements is key. A large fire is not always the best option as a model that is too big for the space you are heating will have to be turned down, which reduces efficiency, creates more emissions and produces unburnt contaminants (from incomplete combustion) which over time can damage the firebox and flue system. The right size Metro fire with correct operation and good dry firewood will provide you many years of warmth and reliable heating.

Choose a suitable model for your homes size, age and the area you are wanting to heat. If you have a medium sized well-insulated home in a region that experiences a mild winter climate, then 10kW of heat should be adequate. A larger home, or the same-sized but less well insulated and draughty home, particularly in a colder climate, will require more heat output. In non-open plan homes there’s no point overheating the living area while the rest of the house stays cold. Installation of a heat-transfer system will use the excess heat at ceiling level and distribute it to other parts of your home. This warm air then circulates to create a dry, healthy environment throughout your home from the one heat source – your Metro fire.

Measure the area (m2) you wish to heat and compare it to the heating area detailed with each model. Homes with a high stud, lack of insulation or the installation of a wetback or heat transfer system may require more heating capacity. Your Metro agency and installer can provide assistance with choosing the best fire and flue system and the additional heating accessories you may need. Selecting the most suitable installation location for your new fire is also important to ensure specified clearances, floor protector requirements, flue installation and optimum heat distribution are achieved.

Installation options

Freestanding Installation

Freestanding models are installed against a wall or into a corner situation with the ECO Flue Kit.

Insert Installation

Insert models are ‘inserted’ into an existing masonry chimney and installed with the ECO Insert Flue Kit.

Built-In Installation

Built-In models are ‘built’ into a timber framed cavity and installed with the ECO Built-In Flue Kit.

Model options

Clean air approved

These models are suitable for any size property and can be installed into a clean air zone anywhere in New Zealand, unless more stringent regional rules apply.

Clean air models comply with the Ministry for the Environment (MfE) National Environmental Standards (NES). NES require less than 1.5gms of particles for each kilogram of dry wood burned (g/kg) and a minimum thermal efficiency of 65%.

The majority of the Metro clean air approved models are also NES compliant with a wetback fitted.

Ultra low emission

ULEB is an acronym for ‘Ultra Low Emission Burner’. Put simply, they are some of the cleanest solid fuel burners on the market with incredibly low emissions.

Tested using the real-life operating test conditions of Canterbury Method (CM1), Metro Ultra Fires meet the Environment Canterbury emission and efficiency standards as well as the MfE National Environmental Standards.

Approved to install anywhere in New Zealand including the Canterbury, Nelson and Rotorua regions.

LTD rural (2Ha+)

LTD models are specifically designed for lifestyle and rural properties and can only be installed on a property with a land area of two hectares or greater.

The main benefit of an LTD model is the responsive control of burn rate allowing overnight burning capabilities with correct operation. 

The unique firebox design delivers longer burn times and all models can be fitted with either a 3kW or 4kW wetback ensuring winter warmth, cooking and water heating are all dominant features.
