Need a compact solution that doesn't compromise on power?  Look no further. If you specify or install our Stratton Mk3 wall-hung condensing boilers in outputs of 40 – 70kW, in a cascade on our low height frame and header kit, it’s the most compact cascade solution on the market!

Suitable for projects where location and space can present a challenge, the Stratton Mk3 wall-hung condensing boiler units up to 70kW feature a compact footprint (487w x 577d x 764h).  What’s more, when fitted to one of our low height frame and header kits it benefits from a height of only 1474mm, from the floor to the top of the boiler flue connection, making it the perfect solution for low height plant rooms. 

For the most compact configuration on the market, cascade the Stratton Mk3 units in outputs of up to 70kW to achieve 270kW. Boilers with comparable outputs from other manufacturers are typically 530mm to 1620mm wide – this makes Stratton Mk3 wall-hung condensing boilers the most compact and space-saving solution by far!

Offering a compact solution for even the tightest of plant rooms, it's more than just the size of a Stratton Mk3 cascade system that sets it apart.  Installing a Stratton cascade offers several benefits over using one large boiler to try and heat a larger building.  For instance, whereas a single appliance trying to supply heat to a large area carries the risk of oversizing, which can result in excessive use of fuel and increased wear and tear, a Stratton Mk3 cascade system allows multiple boilers to work harmoniously together for an efficient and flexible solution.  Moreover, it provides added protection against breakdown.

This was an important consideration for Tucker Mechanical & Electrical Building Services when they were tasked with providing a charity with a reliable and space-saving system to replace the building's existing boiler that had been installed in the 1980s. 

To address the issue of space, two 70kW Stratton Mk3 boilers, with a total output of 140kW, were installed in cascade to provide the building with an alternative to its previous floor-standing model.  Following the upgrade, Hull & East Yorkshire Centre for the Deaf now benefits from a significantly reduced footprint.  Easy to service and clean, the charity can also expect to achieve valuable cost savings on future maintenance intervals.

Suitable for new and retrofit installations, a Stratton Mk3 cascade offers a compact solution, with outstanding efficiency. Stratton Mk3 boilers feature a 5:1 turndown ratio, excellent low-class 6 NOx emissions across all models, and up to 97% gross seasonal efficiency.  Featuring a durable stainless steel heat exchanger for longevity, all Stratton Mk3 boilers offer exceptional system tolerance and are backed by a five-year heat exchanger warranty.  And, to help support the installation of Stratton mk3 wall-hung condensing boilers onto existing heating systems, our latest range of Plate Heat Exchangers (PHEX) provide increased boiler protection and performance.
