One of the most complex aspects of building design is the balancing of the domestic hot water distribution system.
Balancing an open loop plumbing system is particularly difficult because user demand is constantly changing.
In an unbalanced system, it is common for the branch distant to the water heater not having hot water available at the point of use.
Another issue that may occur is water becoming stagnant leading to bacteria growth.
This can lead to frustration for both end users and the building maintenance team due to unacceptable wait times and higher energy costs.
Introducing the TBV, the perfect solution to design a domestic
hot water system that is affordable, dynamic and healthy.
Due to the presence of a heat-sensing element TBV enables automatic balancing
of the flow in the recirculation network, ensuring equal distribution
of hot water at the desired temperature and to all distribution columns.
TBV guarantees that the desired temperature is achieved within each branch through thermostatic balancing, regardless of any changing in system demand.
It also reduces water and energy waste, utility costs and wait times resulting in a more efficient system.
TBV Plus balancing valves are equipped with an additional thermostatic element housed in the second chamber.
When the TBV senses the temparature of 70° the disinfection cartridge expands and a bypass inside the valve opens, allowing higher flow to perform a hot water flush enabling the disinfection process.
TBV Ultra can also perform actuated thermal disinfection when equipped with a thermoelectric actuator.
The actuator on the valve is connected to a building management system allowing the maintenance team to fully control the thermal disinfection process. The actuated thermal disinfection option also allows for zone control in any branch, providing more flexibility and reducing demand on the recirculation pump.
