Factors To Consider In Determining The Appropriate Size For Your Wood Burner

Doors in the Room

The number and type of doors in the room impact heat retention. Factor in the door configuration when deciding on the wood burner size.

Double Glazing Windows

Double-glazed windows enhance insulation. Assess the number and quality of windows in the room, as this can influence the heat requirements.

Outside Walls in the Room

The number of external walls in the room affects heat retention. A room with more outside walls may require a larger wood burner.

Patio Doors

Consider the presence of patio doors in the room, as they can contribute to heat loss. A larger wood burner may be necessary to compensate for this.

Size of Room

The dimensions of the room play a significant role. Calculate the square footage and volume of the space to determine the appropriate heating capacity.

Basic Room Size Guidance:

  • Very Small (up to 2kW)
  • Small (2kW to 5kW)
  • Medium (5kW to 8kW)
  • Large (8kW to 11kW)
  • Extra Large (over 11kW)

Length, Width, and Height

Measure the length, width, and height of the room. This information helps in selecting a wood burner that can efficiently distribute heat throughout the entire space.

Amount of Wood You Plan to Burn

Consider your intended wood usage. If you plan to burn a significant amount of wood, you might need a larger wood burner with a higher output.

Budget

Set a budget for the wood burner, considering not only the initial purchase but also installation costs. Balance your budget with the desired size and features. Determine if a DIY install could save you some money to buy a better-quality wood burner.

If you live in a cold climate with sub-zero temperatures, you may need a more powerful wood burner to maintain a comfortable indoor temperature. We know it’s colder in places in the north of the UK!

Speed to Heat Up the Room

Evaluate the speed at which you want the room to heat up. Larger wood burners with higher output can heat a room more quickly, but if speed isn’t a priority then this should be taken into consideration.

Size of Your Existing Fireplace

If you have an existing fireplace, consider its size. A wood burner that fits well within the fireplace can be a convenient and aesthetic choice.

Taking all these factors into account will help you choose a wood burner that not only suits the size and layout of your space but also operates efficiently and meets your heating needs. Consulting with professionals and considering local climate conditions can further guide your decision-making process.

Other Factors To Take Into Consideration Other Than Size

Which fuel to choose?

The initial and pivotal decision revolves around the type of fuel your stove utilizes. Stoves are available in two variants: multi-fuel or exclusively wood-burning. Multi-fuel stoves are designed to safely burn briquettes and smokeless fuels, in addition to wood. They feature a raised grate with a space beneath for ash to descend into, accompanied by a removable ash pan. It’s worth noting that multi-fuel stoves are not suitable for burning regular coal. On the other hand, stoves dedicated solely to wood burning allow the ash to accumulate in the main firebox, enhancing the efficiency of the burn.

Efficiency And Environmental Impact

Check the efficiency rating of the wood burner. Higher efficiency means more heat is generated from the wood, resulting in cost savings and reduced environmental impact.

UK Laws And Regulations

Wood-burning and multi-fuel stoves in the UK must meet Ecodesign requirements, emphasizing energy efficiency and eco-friendly practices. Installations are subject to Building Regulations compliance, involving the submission of applications to Building Control. The “building notice” approach is often used for smaller projects. Regulations extend to the permissible fuel types, ensuring optimal performance and contributing to environmental conservation. – Read our guide detailing DIY wood burner installs, at least to get an understanding before speaking to an expert!
