It is a well-known fact that heating systems with little, or poor, hydronic balance use significantly more energy. It is for this reason that Danfoss are pleased to bring you an innovative CEN approved TRV.
In contrast to other TRVs which only act as flow limiters, the innovative design of the Danfoss RAS-B2 features a differential pressure controller that ensures all radiators throughout the home get the heat they need throughout the year regardless of whether it is spring, autumn or winter.
Additionally, pre-setting of the desired flow is done on the valve rather than on the lockshield. Something which, it is estimated, could save installers up to two hours of valuable working time.
To make life even easier the time-saving RAS-B2 valve is featured on the Danfoss Installer App which allows installers to calculate, record and document the correct flow and subsequent setting for each radiator on their smartphone or tablet.
Thanks to this innovative product heating installers can now ensure the system is correctly balanced in a fraction of the time it would normally take.
Features and benefits
Even heat distribution increases comfort
Energy consumption is lowered, reducing costs
Condensing boilers run in condensing mode more often
Lower risk of noise results in fewer callbacks
Balance your heating system with Danfoss Dynamic Valve™
How do you overcome common heating system issues such as rushing sounds and overheating? This animation explains in a simple way the common issues, the main cause of them and the solution to solve it. Find out how you can save energy, using Danfoss Dynamic Valves, in more detail.
Available in white/chrome or all chrome the elegant RAS-D² radiator thermostats are ideal for designer radiators or towel rails. The valve bodies are reversible and bi-directional and include a flow-selectable feature to ensure trouble free installation without any risk of water hammer.
The RAS-C² sensor is packaged together with the innovative flow selectable RA-FS bi-directional valve body which can be mounted either vertically or horizontally in flow or return. If water hammer is experienced a patented flow selection device within the valve can be turned to reverse the water direction inside the valve without the need to drain down the system. A quick and easy solution to an otherwise expensive problem.
You save nothing by having one on full throttle and the others closed. In fact, a fully heated radiator will use more heat than 2 or 3 that are turned only a quarter of the up. This is especially true when you use district heating.
When ventilating a room, turn down your thermostat and leave the windows open for 5-6 minutes. If you don’t turn down your thermostat, it will react to the draft by heating up automatically.
Always maintain a minimum of 16 degrees in all rooms. Never go below 14 degrees; this might damage the building and cause dampness, condensation and mould.
Save energy and money by turning your radiators down 2-3 degrees at night. But remember: If you turn them down more than 3 degrees, the money you could save will be used on reheating the room again.
