Electric combi boiler - STB/DTB series

STB/DTB are the newest members of Thermoflow water heating product series. Just like the Compact model, we aim to allow maximum flexibility in terms of power range with this model. To further explore the functionality of this unit, it is designed to have two sets of completely separate water heating systems: one to power central heating and the other for domestic hot water usage. It can be a powerhouse which fuels the entire hydronic system, or supply warm water to make doing dishes no longer a tedious chore.
