The boiler is heating. The tenant freezes.

The boiler is heating. The tenant freezes.


Without hydraulic balancing, many heating systems are inefficient. Boiler and pump work under full load, but many rooms remain cold.

Who does not know that: freezing cold outside. The thermostat is ready to go - and it should be warm and cozy inside. Nevertheless, the heater does not get hot and the stall stays cold. Many residents of penthouses or floors far from the boiler room know how to sing a song about it. But hardly any consumer knows the hydraulic balance and knows how to gain heat and save energy!

Hydraulic balancing helps against heat loss

But why is the radiator only lukewarm? Why do 16, 17 degrees prevail in the room? The answer has to do with simple physics. The water from the heating system seeks the path of least resistance. It leads first through short and thick pipes rather than through long and thin pipes as well as through radiators closest to the boiler. This means that the boiler-side heaters get too hot, but too little at the rear end.

Often, homeowners can help themselves by increasing pumping power or setting a higher flow temperature in the boiler. The heat effect is however only small. And the residents get hot at best when looking at the higher heating billing and the electricity bill for the pump. In addition, the unequal distribution of pressure and heat often causes unpleasant noise on the valves, such as glaciers or hisses.

Heating engineers re-regulate heat distribution

Hydraulic balancing solves these problems efficiently. The qualified heating engineer first collects the data for each individual room. It calculates the required heating load, ie heat and hot water volume. In addition to the room size, it takes into account the insulation of walls, doors, windows and ceilings. It is usually sufficient to hand over the blueprints to the craftsman. The specialist in the heat source, the heat pump and the radiators then provides the corresponding presettings.

The costs for hydraulic balancing are limited. For a detached house of about 150 square meters can be expected with about 500 euros. With savings of up to 25 percent compared to unregulated heating systems, the costs pay for themselves in a very short time. Conversions are usually not necessary. However, hydraulic balancing will be promoted in conjunction with other reorganization measures through KfW loans. And in view of the average of three times oversized heating pumps and in many cases 80 percent to powerful boilers, even these interventions pay off in the long run.
