The Wessex ModuMax mk3 is a compact and lightweight floor standing modular boiler range. This next generation of Wessex ModuMax condensing boilers features improvements such as a 40⁰C differential temperature and enhanced built in Siemens controls for multiple boiler sequencing.

Available in 15 models with outputs from 97kW to 762kW, the fully modulating condensing boilers are able to respond rapidly to changes in demand making them extremely versatile. The heat exchanger is manufactured in high grade stainless steel to provide protection against condensate.

The space saving, vertically stacking design makes the Wessex ModuMax mk3 boiler range ideal for use in city centre developments and district heating networks where space is at a premium.

This download includes all 15 configurations of the Wessex ModuMax mk3 boiler range and has user selectable options for available pipe kits and clearance zones.
