The Low-Loss Header, also known as a Hydraulic Balancer, is designed to separate the circulation of the boiler from the heating system, making it ideal for medium to high-power systems (from 40 kW). It supports multiple boilers and various heating circuits, such as floor heating, radiators, and hot utility water. The hydraulic balancer ensures independent operation of pumps, eliminates the need for separate flow balancing, and incorporates desilter and air vent functions to enhance system performance and protect the boiler from low-temperature corrosion.

Operational Modes:

1. When the heat requirement equals the boiler’s output: system is balanced.
2. If heating demand is less than the boiler’s output: return water from the balancer signals the boiler to reduce power.
3. If demand exceeds boiler output: increased pump suction signals the boiler to increase power.

SHE Hydraulic Separators – Headers for Central Heating Systems

A properly designed central heating system should deliver reliable, efficient, and energy-saving performance for many years. One of the key components responsible for achieving these results is a hydraulic separator. This essential element is widely used in both modern and upgraded heating installations, ensuring the stable and efficient operation of the entire system.

SHE hydraulic separators are suitable for heating systems powered by solid fuel boilers, condensing boilers, and heat pumps. In solid fuel boiler installations, they effectively protect the boiler against excessively low return water temperatures, helping to extend the service life of the heating equipment and improve its reliability.

What Is the Purpose of a Hydraulic Separator?

The primary function of a hydraulic separator is to hydraulically separate the heat source circuit from the heating distribution circuit. This allows flow rates and pressure differences between the individual circuits to be balanced, enabling each circuit to operate independently and efficiently.

Hydraulic separators are particularly beneficial in installations where the required flow rate on the heat source side differs from that of the heating system. They are also an excellent solution for underfloor heating systems, where the temperature difference between the supply and return water is relatively small.

Hydraulic separators are commonly used in:

• systems with wall-mounted boilers equipped with integrated circulation pumps,
• compact heating units with a low water volume,
• heating systems featuring multiple heating circuits.

By maintaining the correct water flow rate, a hydraulic separator effectively separates the boiler circuit from the heating circuit, resulting in improved system stability, enhanced operating efficiency, and greater user comfort.
