Benefits of optimally balancing a heating system

Eclipse offers an optimally balanced heating system to create a constant room temperature, enhancing its efficiency and saving on energy costs.



Eclipse is a quick, easy and secure solution for two-pipe radiator heating systems. There are no complex piping and pressure loss calculations necessary. During the heating up phase and after lowering the individual room temperature, it immediately provides the required flow at the radiator. The flow rate is set directly at the valve: for a fast and cost-efficient installation.

It also maintains the perfect flow without any noise and optimises radiator and boiler efficiency to maintain the required room temperature – even if other valves are closed. As heating is based only on demand, it enhances the efficiency of the system and saves costs.

The smaller size of the TRV fits all renovation applications and provides more mounting options, including straight, angle, double angle, right and left body housings. Because of the new standard valve body dimension, replacing old valves is easy. Eclipse thermostatic valve bodies have the same size as V-exact II standard valves. They are perfect for systems with unknown piping or small systems with non-reduce able pump head >15kPa.

Eclipse valves are EN 215 approved and keymark registered. The whole AFC technology range includes products for all types of radiators and underfloor heating – Eclipse, Multilux 4-Eclipse-Set, Vekotec Eclipse, Multibox AFC, Dynacon.



Irrespective of the differential pressure, the valve controls the flow rate to the value pre-set. Thanks to the automatic flow control technology only the flow rate has to be defined. The flow rate is directly set at the valve with a setting key or an end wrench. Thanks to the optimum noise characteristics the valve can be used for differential pressures up to 60 kPa and therefore no differential pressure controllers are necessary.

This functionality increases radiator heating efficiency and saves on energy consumption in comparison to normal thermostatic valves without AFC technology.

Eclipse is easy to install. No complex calculations for hydraulic balancing are necessary. The new and now standard EN 215 product dimensions allow absolute flexibility in all kinds of renovation projects. The flow rate is set directly at the valve and the hydraulic balancing is easily done. Also partial system start ups are possible. Even system extensions have no influence to the balancing of the existing systems.

Its added flexibility also allows you to update, check or replace the insert while the system is in operation and without the need for draining – saving you time on installation.
