Description

The Zosia Deco Wood Burning Boiler Fireplace Insert 14kW is a powerful and efficient heating solution designed for homeowners seeking both high heat output and integration with a domestic hot water system. Built for performance, durability and everyday practicality, this premium boiler insert is ideal for larger homes where reliable, whole-house heating is essential.

At the core of the Zosia is an advanced heat exchange system featuring integrated flame tubes and an elevated flue design, significantly increasing the surface area for heat transfer. This allows the fireplace to extract more energy from every burn, improving overall efficiency and delivering strong, consistent heat output even in demanding conditions.

A sophisticated triple air combustion system ensures clean and controlled burning at every stage. Primary air supports ignition and flame stability, while secondary air is introduced through the rear wall to promote afterburning of gases. This process improves efficiency, reduces emissions and ensures compliance with modern Ecodesign and BImSchV 2 standards, making it a responsible choice for environmentally conscious homes.

The integrated 125mm external air intake allows the Zosia to operate efficiently in modern, airtight properties, including homes with mechanical ventilation or heat recovery systems. Combined with a precise airflow damper, the user gains full control over combustion performance and heat output.

For everyday comfort and convenience, the insert includes an air wash system that helps keep the large heat resistant ceramic glass cleaner for longer, maintaining a clear and attractive view of the flames. A cold handle system enhances safety by allowing safe adjustment even during operation, while a removable grate and ashpan make cleaning and maintenance straightforward.

Designed with strength in mind, the Zosia is manufactured using laser cut steel components formed with CNC precision machinery, ensuring long term structural reliability and a tight, secure combustion chamber. Its reinforced construction makes it well suited to continuous use within central heating systems powered by a back boiler.

Combining high output performance, advanced combustion technology and modern design, the Zosia Deco Boiler Fireplace Insert delivers an exceptional balance of efficiency, practicality and visual appeal for contemporary living.

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.
