Getting the Most Out of Your Heat Pumps Using TRVs
Heat pumps are growing in popularity as they improve the efficiency of energy systems and can reduce bills by up to 26%*. They can be a costly investment that needs to be protected and as such careful consideration should be used when selecting components to optimise and protect each part of the system.
During the ‘start-up’ period of a heating cycle, the heating circuit, if incorrectly balanced, can pull an excessive amount of energy. This is because there is a large initial temperature difference between the flow and return pipework. This large draw of energy can negatively affect the operation of a heat pump.
Independently managing flow rates
Any system that has a heat pump as its energy source would benefit from installing an automatic dynamic balancing valve. By accurately managing the flow rates throughout the heating circuit using a flow settable, pressure independent, thermostatic radiator valve (TRV), an Installer can optimise their design and ensure each part of the system receives the correct amount of energy independently thus increasing the working life of the compressor within the heat pump.
In addition, any hydronic circuit serving a secondary system must be balanced, meaning that it must be constructed in such a way as to guarantee the design flow rates of the thermal medium. Due to this, specific balancing devices are required depending on the varying system types and appliances used.
What is the DYNAMICAL® TRV?
The DYNAMICAL® Thermostatic Radiator Valve allows the automatic dynamic balancing and pressure-independent adjustment of the heating system. The device, in conjunction with a thermostatic, electronic, or thermoelectric control, combines different functions in a single component.
The valve can balance the heating system automatically, ensuring each terminal receives the set flow rate. Even in the case of partial circuit closure, by means of the regulating valves, the flow rates in the open circuits remain constant at the set value- a vital feature when being installed on systems powered by heat pumps.
By using the DYNAMICAL® in combination with thermostatic control heads, the surrounding temperature can remain automatically constant, thus guaranteeing effective energy saving.
