Equipped with the ACVMax burner and modbus controls.
Total Condensing unit - condenses in both heating and hot water mode.
Can provide heating and hot water or can be used as a stand alone hot water generator.
Can deliver an exceptional peak and continuous volume of hot water.
Stainless Steel domestic hot water tank - no glass lined steel or anode protection required.
Space saving footprint - Heating and hot water from one unit reduces plantroom space requirements.
Stainless steel heat exchanger reduces maintenance and can increase system lifespan.
Floor standing boiler with large volume of primary water, ideal for existing heating systems.
Multiple units can be linked for larger applications or back up
Can be installed along with Prestige heat only boilers or Smart cylinders to provide a perfect solution to your heating and hot water requirements.
