Stratton mk3 boiler

Our Stratton mk3 wall hung boilers are among the most compact on the market when installed in configurations of up to 4 in cascade on our low height frame and header kit. Suitable for projects where location and space can present a challenge, 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 a Hamworthy Heating low height frame and header kit, it benefits from a height of only 1474mm, from the floor to the top of the boiler flue connection. This makes it the perfect solution for low height plant rooms. Try out our Stratton System Selector to build your wall-hung compact cascade, HERE.

Single units can be cascaded for larger installations up to 900kW (6 x Stratton mk3 150kW boilers).

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.

To help support the installation of Stratton mk3 wall-hung condensing boilers onto existing heating systems, the Hamworthy range also includes a selection of Plate Heat Exchangers (PHEX) to provide increased boiler protection and performance. Find out more about Plate Heat Exchangers HERE.
