Description

The MB120 Lift-Up Glass Wood Burning Fireplace Insert 20kW is a premium high output heating solution designed for large contemporary homes that demand powerful performance and refined modern styling. Combining advanced combustion engineering with a sleek steel construction, it delivers exceptional heat output while creating a bold architectural feature through its wide, uninterrupted flame view.

Built from high grade steel resistant to extreme temperatures, the MB120 is engineered for long term durability and reliable operation under high heat conditions. Its robust construction, combined with precision laser cutting and CNC bending, ensures structural stability and airtight performance suitable for demanding installations.

At the core of the system is a TERMOTEC lined combustion chamber, designed to absorb and retain heat for longer periods. This increases internal combustion temperature, improves efficiency and extends heat output, allowing for more effective use of fuel and reduced consumption.

An advanced heat exchange system featuring a tall flue outlet and horizontally arranged fire tubes increases the surface area for heat transfer. This allows more heat to be delivered into the room while lowering flue gas temperatures, improving overall system efficiency.

A sealed door construction with reinforced steel profiles ensures excellent stability and airtight operation, while precision gasket channels maintain long term sealing performance even under intensive use. A deflector system extends the flue gas path, enabling more complete combustion and improved energy recovery.

Fresh air is supplied exclusively from outside via a 125mm external air intake, making the MB120 ideal for modern airtight homes. A single intuitive control lever allows precise regulation of combustion air for consistent and efficient burning.

The triple air system combines primary air to the combustion base, secondary air from rear chamber inlets and a clean glass air curtain system. This ensures efficient combustion while helping maintain a clear flame view with reduced soot build up.

A lift up guillotine door system supported by a balanced mechanism allows smooth and effortless loading of larger logs, while a secondary side opening function simplifies cleaning and maintenance. A safety locking system ensures secure operation during use.

The large heat resistant ceramic glass panel, rated up to 660°C, provides a panoramic flame view that enhances the atmosphere of any interior. The minimalist steel frame design amplifies the visual impact of the fire, making it a strong focal point in modern living spaces.

Fully compliant with modern efficiency and low emission standards, the MB120 20kW insert is a powerful, reliable and visually striking solution for homeowners seeking a high performance wood burning fireplace insert with contemporary design and exceptional heating capability.

Warranty

All products sold by Halcyon Fireplaces are brand new and supplied by Halcyon Fireplaces as an authorised retail partner of KRATKI.

Eligible products are supplied with the applicable KRATKI manufacturer warranty, subject to the manufacturer’s official warranty terms and any product-specific exclusions.

KRATKI provides:

  • A 5-year manufacturer warranty covering the proper functioning of the fireplace or stove from the date of purchase.
  • A 1-year manufacturer warranty covering fireplace grates and seals.

The manufacturer warranty does not cover heat-resistant ceramics, including fireplace glass, except where otherwise stated in the applicable warranty terms.

To maintain the validity of the manufacturer warranty, the appliance must be installed, operated and maintained in accordance with the manufacturer’s instructions and all applicable UK building, ventilation and chimney regulations.

Halcyon Fireplaces will assist customers with valid warranty claims and, where appropriate, liaise with KRATKI on the customer’s behalf.

The manufacturer warranty is provided in addition to, and does not affect, your statutory rights under UK consumer law.

Returns and Refunds

At Halcyon Fireplaces, we want you to be satisfied with your purchase. Due to the size, weight and specialist nature of fireplaces, returns must be handled carefully.

To request a return, please contact us within 30 days of delivery.

For online consumer orders, your statutory cancellation rights include the right to notify us that you wish to cancel within 14 days of receiving the goods. You then have a further 14 days to return the goods.

Returned items must be kept in good condition and, where reasonably possible, returned with their original packaging, pallet and protective materials.

Fireplaces that have been installed, connected, used or damaged after delivery may not be eligible for a change-of-mind return. This does not affect your rights where goods are faulty, damaged on arrival, incorrectly supplied or not as described.

Halcyon Fireplaces can arrange collection from your property at a pre-agreed date. The cost of collecting a non-faulty change-of-mind return will be confirmed before collection and may be deducted from the refund where permitted by law.

No collection charge or restocking charge will apply where goods are faulty, damaged on arrival, incorrectly supplied or not as described.

Where returned goods show handling beyond what would reasonably be permitted when examining them in a shop, we may make a lawful deduction for any reduction in value.

Refunds

Refunds will be processed after the returned goods have been received or collected and inspected.

Refunds will be made to the original payment method.

Where the statutory cancellation right applies, refunds will be issued within 14 days of receiving the returned goods or receiving acceptable evidence that the goods have been returned.

Where applicable, the original standard delivery charge will also be refunded. Additional charges paid for an enhanced or expedited delivery service are not refundable beyond the cost of standard delivery.

Banks and card providers may take additional time to display the refunded amount.

Important Notes

Fireplaces are heavy and are often delivered on pallets. For safety and to reduce the risk of damage, we recommend using the collection service arranged by Halcyon Fireplaces.

Any collection cost or deduction will be explained clearly before the return is completed.

Nothing in this policy limits or excludes your statutory rights.

FREE standard UK delivery is available on orders over £300. Orders below £300 are charged £10.
