      Please do not travel to collect your order until we have confirmed that your goods are ready. We recommend contacting us in advance to confirm stock availability, collection times and loading details.

      Please ensure you arrive in a suitable vehicle for the size and weight of the goods being collected. Our team can assist with loading where safe and practical, but the customer is responsible for securing the goods for transport.

      Delivery Information

      Delivery times are usually approximately 2–3 working days, depending on stock availability at the time of order or if stated otherwise. Some products may have longer lead times, especially if they are made to order, supplier stocked or awaiting manufacturer availability.

      Once your order has been placed, we will contact you to confirm the estimated delivery date and advise you of any known delays.

      Delivery costs are calculated at checkout based on your postcode, order value and delivery location.

      Free Delivery Over £1,000

      Free delivery on orders over £1,000 is available within 100 miles of our showroom at RG7 2PQ, unless stated otherwise.

      Unless otherwise agreed in writing, free delivery is a dedicated one person small van / 3m Sprinter-style delivery service.

      This means:

      • the goods are delivered to your address or the nearest safely accessible point;
      • the delivery is made by one driver;
      • the receiver is responsible for safely unloading the goods from the vehicle;
      • the driver may assist where safe and practical, but this cannot be guaranteed;
      • this service does not include tail lift delivery, two-person delivery, white glove delivery, internal placement, unpacking or installation.

      For heavy, fragile or bulky products, please ensure suitable unloading assistance is available at the delivery address.

      If you require help unloading, a tail lift vehicle, two-person delivery, white glove delivery, internal placement or any other special delivery arrangement, please contact us before placing your order or before dispatch so we can provide a bespoke delivery quote.

      Dedicated Delivery Service

      Where possible, we use a dedicated direct delivery service rather than a general pallet network. This helps reduce handling, lowers the risk of damage in transit and gives larger or fragile products the best chance of arriving safely and in one piece.

      However, unless an upgraded delivery service has been quoted and agreed in writing, this remains a one-person delivery service and the receiver is responsible for unloading.

      Tail Lift, White Glove and Bespoke Delivery

      Tail lift, two person and white glove delivery options may be available on request, depending on the product, delivery location and access.

      These are upgraded chargeable services and must be agreed before dispatch.

      Please contact our team on 0118 970 1717 or email info@bonfire.co.uk if you require:

      • tail lift delivery;
      • assistance unloading;
      • delivery onto a driveway or into a garage;
      • white glove delivery;
      • delivery into the property;
      • restricted access delivery;
      • timed delivery;
      • delivery to a building site or commercial address.

      Access Requirements

      Please tell us before dispatch if there are any access restrictions, including:

      • narrow lanes;
      • steep or gravel driveways;
      • low bridges;
      • parking restrictions;
      • steps;
      • restricted turning space;
      • weight limits;
      • difficult access for vans or lorries.

      The driver will deliver to the nearest safe and accessible point. Due to insurance and health and safety restrictions, drivers are not insured to move goods into your home unless a suitable upgraded delivery service has been agreed in advance.

      Checking Goods on Delivery

      Please check all goods while the driver is present. The driver can usually wait up to 15 minutes.

      If any damage is visible, please mark this clearly on the delivery note and notify us as soon as possible. Any damage must be reported within 48 hours of delivery.

      If you are unavailable on the scheduled delivery date, re-delivery charges may apply.

      We provide delivery within a 200-mile radius of our Reading, Berkshire showroom. For customers outside this radius, products may be available for collection only, or we may be able to quote for a bespoke delivery solution.

      For delivery questions, please call 0118 970 1717 or email info@bonfire.co.uk.

      The Stûv 21/105 SF Single Faced Inset Wood Burning Stove is a wide single-sided built-in wood burning fire designed to combine a clean architectural look with strong heating performance and a retractable glass system. As part of the Stûv 21 family, it can operate as a closed high-efficiency stove with the glass lowered, or as an open fire when the glass is raised.

      What makes the 21/105 SF especially distinctive is its proportion. It is wider than the mid-size single-sided models, giving a broader flame picture and stronger visual presence, while still being designed for architectural integration into masonry, cladding or ready-to-fit fireplace systems. The retractable glass rises fully out of sight on this model, creating a very clean open-fire presentation. With the glass lowered, the fire benefits from precise combustion control, high airtightness and a strong view of the flames through a large glazed opening. The pivoting door also makes maintenance easier by giving access to the glass and mechanical parts.

      In performance terms, the 21/105 SF offers a rated output of 19.8 kW, an optimal range of use from 8.2 to 24.8 kW, 79.7% efficiency at rated power and an energy efficiency class of A. It accepts 80 cm logs, weighs 224 kg, and uses a 200 mm flue outlet. It also supports outside air connection, optional barbecue use, and a range of cladding and façade solutions to suit different interiors.

      Key Features:

      • Single faced inset wood burning stove
      • Retractable glass door
      • Open or closed fire use
      • Full glass raise on this model
      • Wide architectural fire view
      • Rated output 19.8 kW
      • Operating range 8.2 to 24.8 kW
      • 79.7% efficiency
      • Energy efficiency class A
      • Accepts logs up to 80 cm
      • Outside air connection
      • Pivoting glass for cleaning
      • Optional barbecue
      • Optional claddings and facades
      • Optional ventilation solutions

      Expert Insight

      The 21/105 SF is a useful option where the customer wants a broader single-sided fire than the 95 model, but not as large as the 125. Its ability to fully raise the glass out of sight is an especially important detail, as this model is only offered in that full-raise configuration, which strengthens the open-fire effect.

      Suitability

      The Stûv 21/105 SF Single Faced Inset Wood Burning Stove is well suited to architectural fireplace projects, modern living spaces and interiors where a wide single-sided fire is wanted with both open-fire atmosphere and closed-fire efficiency.

      Installation / Technical Notes

      This model weighs 224 kg, accepts 80 cm logs, uses a 200 mm flue, and requires a minimum combustion air section of 100 cm². Minimum insulation thickness is listed as 14 cm at the back, 15 cm at the sides, 1 cm above and 18 cm below.
