      Delivery, Click & Collect & Returns Information

      Collection Information

      We offer free Click & Collect from our Reading, Berkshire showroom and warehouse at RG7 2PQ.

      Please select “Click & Collect: Berkshire Showroom (RG7 2PQ)” at checkout to reserve your item.

      If the Add to Basket button is not available, please call 0118 970 1717 or email info@bonfire.co.uk to place a Click & Collect order.

      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 21/75 DF Double Sided Inset Wood Burning Stove is the most compact double-sided model in the Stûv 21 range, designed to bring a see-through real fire into two adjoining spaces without requiring the scale of the larger models. With retractable glass on both sides, it delivers transparency, flexibility and strong heating performance in a more manageable format.

      The double-sided design allows the fire to be viewed from both rooms, making it ideal for dividing spaces while keeping them visually connected. The retractable glass can be raised to create an open-fire effect, while lowering the glass turns the appliance into a sealed high-efficiency stove. The glass door system is carefully designed so the runners and mechanism stay hidden, preserving the clean look of the opening. The door also tilts forward for easier cleaning and maintenance.

      In performance terms, the 21/75 DF offers a rated output of 18.0 kW, an optimal range of 8.0 to 22.8 kW, 75.8% efficiency at rated power and an energy efficiency class of A. It accepts 50 cm logs, weighs 187 kg, and uses a 250 mm flue outlet. It also supports outside air connection, optional air ducting, optional fan assistance and optional barbecue use.

      Key Features:

      • Double sided inset wood burning stove
      • Retractable glass on both sides
      • See-through fire
      • Open or closed fire use
      • Rated output 18.0 kW
      • Operating range 8.0 to 22.8 kW
      • 75.8% efficiency
      • Energy efficiency class A
      • Accepts logs up to 50 cm
      • Outside air connection
      • Air ducting possible
      • Optional fan
      • Optional barbecue
      • Hidden mechanism design

      Expert Insight

      The 21/75 DF is useful where a double-sided retractable fire is wanted but the installation cannot accommodate one of the wider DF models. It still delivers strong heat output, but in a narrower format that is easier to integrate between more compact spaces.

      Suitability

      The Stûv 21/75 DF Double Sided Inset Wood Burning Stove is well suited to smaller room-dividing fireplace projects, two-room connections and interiors where a see-through fire is wanted without the full scale of the larger models.

      Installation / Technical Notes

      This model weighs 187 kg, accepts 50 cm logs, uses a 250 mm flue, and requires a minimum combustion air section of 200 cm². Minimum insulation thickness is listed as not specified at rear, 14 cm at the sides, 0 cm above and 13 cm below.
