Description

The MBM Wood Burning Boiler Fireplace Insert 12kW is a high performance heating solution designed for homeowners seeking powerful heat output alongside integration with a domestic hot water system. Built from high temperature resistant steel and engineered for long lasting reliability, this premium boiler insert combines advanced combustion technology with efficient heat transfer to deliver exceptional whole home heating performance.

At the core of the MBM is a sophisticated water heating system that captures energy from the flue gases and transfers it directly into a central heating circuit. This allows the fireplace to function as both a room heater and a highly efficient boiler, making it an excellent choice for energy conscious homes seeking to reduce reliance on conventional heating systems.

The combustion chamber is lined with TERMOTEC, a heat retaining material that increases internal temperatures and improves combustion efficiency. A double deflector system extends the exhaust gas path, ensuring more complete fuel combustion and maximising heat recovery while reducing emissions in line with Ecodesign standards.

A built in external air intake with adjustable control ensures a consistent and regulated airflow, making the MBM suitable for modern airtight homes and properties with mechanical ventilation systems. The triple air supply system, including primary air, secondary air and a dedicated air wash curtain, promotes clean combustion while helping to maintain a clearer view of the flames.

Designed with precision engineering, the insert features laser cut steel construction, CNC formed components and reinforced sealed door profiles for exceptional structural stability and airtight performance. The advanced door system operates on a counterbalanced pulley mechanism, allowing smooth lift up operation for effortless loading while maintaining a secure seal during combustion.

A large heat resistant ceramic glass panel rated up to 660°C provides a clear and immersive view of the fire, enhancing both atmosphere and visual appeal. The air wash system further helps reduce soot build up, ensuring the glass remains cleaner for longer.

Fully compliant with Ecodesign and BImSchV 2 standards, the MBM Boiler Fireplace Insert delivers environmentally responsible heating with low emissions, high efficiency and dependable performance. It is a powerful and versatile solution for those looking to integrate a real wood burning fireplace into a modern central heating system.

KRATKI provides:

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.
