Circulation unit is a compact set of devices, consisting on various, carefully selected components. Having a circulation unit installed brings many benefits to both the investor and the installer.<\/strong><\/p>\n

There are different kinds of circulation units available in the market. Some circulation units are dedicated to solid fuel-powered domestic installations, while others work well for heat pump or gas boiler systems with e.g radiators or underfloor heating installations. Below, we\u2019re discussing 4 essential benefits brought to the installer by choosing a circulation unit\u00a0with an actuator.<\/p>\n

1. Less selection errors<\/strong><\/h3>\n

As a complete unit, the GRA200, GRA300 series circulation unit\u00a0with actuator frees the installer from having to choose and match all individual fittings and accessories. The components used (progressive valve, rotary actuator, circulation pump, among others) have been selected to ensure outstanding flow control. The installer, then, doesn\u2019t have to worry about oversizing the valve or possible incompatibility, e.g. in terms of actuator type and its rotation time. The circulation unit is also equipped with a check valve\u2014a thing sometimes overlooked by installers when they go for separate devices.<\/p>\n

Having a circulation unit installed does reduce errors\u2014but it doesn\u2019t mean that no mistakes can be made. When choosing a device according to installation requirements, several criteria have to be followed. These are:
\u25cf\u00a0\u00a0 \u00a0system power,
\u25cf\u00a0\u00a0 \u00a0\u0394T of the system,
\u25cf\u00a0\u00a0 \u00a0Kvs (stated in m3\/h, calculated based on system power and \u0394T).<\/p>\n

Also note that certain water-glycol mixtures used in floor heating circuits may affect pump efficiency.<\/p>\n

2. Quick installation<\/strong><\/h3>\n

Installing a circulation unit takes much less time than having all individual components installed. Installation should be done as instructed, which can be summarised as follows:<\/p>\n

1.\u00a0\u00a0 \u00a0Prepare and clean the surface where the circulation unit is to be placed.
2.\u00a0\u00a0 \u00a0Remove the insulation shell from the circulation unit in order to access the connections.
3.\u00a0\u00a0 \u00a0Attach and seal the screws. Apply gaskets. Tighten all pipes.
4.\u00a0\u00a0 \u00a0Assemble the insulation shell and connect power.
5.\u00a0\u00a0 \u00a0Turn on the pump. Make sure it is working correctly, and that there are no leaks in the system.<\/p>\n
