What’s the hydraulic balance?

It consists in the balance of the water flow in its water heating network thanks to an efficient repartition.

Which is the cause for the imbalance in a hot water circuit?

The cause of this bad flow repartition is the disparity of the pressure losses between the different paths of the water in the installation. These pressure losses are caused by the floors of the building, the diversions of the pipe network.

Why is it important to balance the hydraulic balance?

You observe that the radiators on each floor or the one located at the bottom of your residence (the farthest respect to the dispensing pump of your boiler), don’t work properly or are cold.

Water always choose the shortest way. This is why the first water column or the first heating equipment (radiator) are supercharged and the columns and the equipment at the bottom of the network are undercharged. Energy is not only wasted, but also the comfort of the residence is affected.

A good installation include also:

  • Energy saving
  • Optimal ambient temperature
  • Good heat efficiency
  • No flow noises
  • •Optimal aptitude for the system regulation

How to balance the hydraulic balance?

There are many different solutions to balance the hydraulic network.

- Regulation or pre-regulation corner/right holder:

They must be installed on the heater outlet.

Install it on each radiator of the network: it allows to regulate the water flow opening more or less the valve. It also allows to isolate the radiator in order to perform works without emptying the rest of the installation.

- Thermostatic body with pre-regulation:

They are to be installed at the radiator entry: They allow the installation of a thermostatic head and the regulation of the incoming water flow.

To simplify your life, the manufacturer Honeywell propose some radiator equipment kits composed of:

  • A thermostatic head
  • A thermostatic body
  • Regulation corner holder
