This free commissioning promotion applies to all Stratton Mk3 models ordered between April 1 and invoiced by December 31, 2025, and offers customers the opportunity to optimise their system’s performance from the outset. For added peace of mind, each boiler is also backed by a 5-year warranty.

The Stratton Mk3 range incorporates advanced stainless steel heat exchanger technology, ensuring exceptional durability and system tolerance. Available in seven models with outputs ranging from 40kW to 150kW, single units can also be cascaded to meet higher demands or larger installations.

Ideal for refurbishment and retrofit projects, the Stratton Mk3 features a 5:1 turndown ratio and low Class 6 NOx emissions across all models, delivering up to 97% gross seasonal efficiency. Its compact, lightweight design is also perfect for space-constrained plant rooms. With models up to 70kW measuring just 487mm wide, 577mm deep, and 764mm high, the Stratton Mk3 wall-hung condensing boiler offers a smaller footprint than many other models on the market. When fitted to a Hamworthy Heating’s low-height frame and header kit, the Stratton Mk3 provides the most compact cascade configuration available for outputs from 40kW to 70kW.

The Stratton Mk3 range is also available with a range of easy-to-install AHRI certified® plate heat exchangers designed to enhance energy efficiency and performance. These compact, lightweight exchangers feature 316 stainless steel plates with copper brazing, to ensure maximum durability.

This latest free commissioning offer highlights Hamworthy Heating's commitment to exceptional service and reinforces its ongoing dedication to providing energy-efficient solutions that guarantee long-term performance and reliability.
