Wessex ModuMax is a compact, floor standing, high efficiency condensing boiler range with up to 95% gross seasonal efficiency.

All models feature the latest fully modulating burner technology with 100% to 20% modulation on each module, and hot surface ignition with 120V power transformer.

The Wessex ModuMax mk3 is available in individual condensing boiler modules of 97 kW, 116 kW, 147 kW, 196 kW and 254 kW and in a choice of one, two or three-modules high pre-assembled boiler stacks, giving 15 combinations of like powered modules. This effectively offers 13 output power options ranging from 97 kW up to 762 kW.

The heat exchanger is manufactured in high grade stainless steel to provide protection against condensate and corrosion. Each module is designed to operate continuously at up to 40 °C delta T differential temperature rise across the module, maximising condensing operation. The mk3 upgrade of the boiler has been developed in direct response to the increased use of wider delta T design methodologies in commercial buildings and district heating systems.

Wessex ModuMax mk3 boilers feature modern controls and use a LPB (Local Process Bus) communication system. Clip-in modules allow boiler controls to be integrated with building control systems. Sequencing for up to 16 boilers in a multiple boiler installation is achievable via Merley sequence controller option, or by using the built in master/slave cascade control.

Completing the Wessex ModuMax package is a range of optional pipe kits that simplify design and installation. The variety of kits is available for 2 or 3 modules and factory tested and assembled for ease of installation.
