Optimize heating and save heating costs

Have hydraulic balancing carried out: optimize the amount of water

The radiators on the lower floors are warmer than on the upper floors? The individual components of the heating system, i.e. the heating pump, lines and body, could not be precisely matched to one another. Often a much too large amount of water is transported through individual radiators and too little arrives in others. This is inefficient, increases the heat loss from the heating system and increases the power consumption of the circulation pump.

Hydraulic balancing saves approx. 5% heating costs

In this case, hydraulic balancing is recommended: Hydraulic balancing optimizes the amount of water in the pipes and radiators. This will heat all rooms in the building evenly and you can use an annual Savings of 5% on your heating costs calculate.

Hydraulic balancing is generally useful for all buildings - regardless of the age of the building! Hydraulic balancing is particularly recommended for condensing boilers. Because these devices only work extremely efficiently when the return temperatures are as low as possible. If natural gas is used as fuel, this temperature should be below 56 ° Celsius.

Important: The hydraulic balancing should be carried out by a specialist company with appropriate experience.

There are 2 procedures:

  • With the simple method, the heating requirement of all rooms, also known as the heating load, is estimated. The heating is optimally adjusted on the basis of this estimate. It is particularly suitable for existing buildings.
  • The second method is much more precise and therefore more recommendable, but also more expensive. The heating load is calculated exactly for each room. This precise procedure is suitable for both existing and new buildings. It can be subsidized as part of construction supervision.

Adapt heating control to requirements

If the control of your heating system is not optimally set, this can result in higher heating costs or temperatures that are too low. The control automatically adapts the generation and distribution of heat to your current needs so that the energy source (e.g. gas or wood pellets) is used as efficiently as possible. You can set it correctly, for example Save 5% on your heating costs. The prerequisite for this is that the heating system is set correctly. Then it delivers the desired room temperature fully automatically.

Set the flow temperature correctly

The flow temperature of the heating system can be adjusted to the ambient temperature. This happens either depending on the measured outside temperature (weather-dependent) or the room temperature (room temperature-dependent). In the case of weather-compensated control, a Temperature sensor on the outside wall of the building, the control via the current temperature. The colder it is outside, the higher the flow temperature. This allows an experienced specialist company to set the so-called heating curve for each building according to the renovation status and your personal needs. If the setting is correct, the desired room temperatures are achieved and energy consumption is minimized at the same time. Ideally, the flow temperatures should be set as low as possible so that the rooms are still warm enough when the thermostat valves are fully open - usually level 5! Even in very well insulated buildings, the individual setting of the heating is important in order to save energy and costs.

Modern regulations can also be connected to the Internet: Weather forecast tools then inform you in advance about upcoming temperatures. This allows you to react to temperature fluctuations even faster than with the outside temperature sensor - and save more energy.

The heating control can also be over Time programs, also set "timer". Then you can set the heating to night setback or night shutdown depending on the time of day or personal needs. With night setback, the boiler and pump continue to run at a low temperature, with night shutdown they remain off.

So-called self-learning controls even adapt to fluctuating outside temperatures. They automatically determine when the heating must start with night setback or with heating so that the specified room temperatures can be reached at the right time.

It is also possible to control modern heating systems using a smartphone or tablet. You can use it to control the temperature when you are out and about when nobody is at home. This saves energy costs and increases comfort when the heating is already warm when you come home.

5 tips for setting up the heating system

  1. Set different reduction times for working days and weekends for controllers with a weekly program.
  2. Adjust the heating control to the summer and winter time. New regulations usually do this automatically.
  3. Are you going on vacation? In summer you should switch off the heating control for hot water on the day before departure. In winter it is good to switch on the frost protection or setback mode if you are absent for a longer period of time. Please note, however: It can take 1 to 2 days to heat up a cooled down building.
  4. If it is cold outside: Make sure that the temperature in the house does not drop below 16 ° Celsius when you switch it off at night. If it does: switch to night reduction.
  5. If it's rather mild outside: Switch from night setback to night shutdown.

Replace heating pump: reduce power consumption

The heating pump keeps the heated water circuit running between the boiler and the radiators. It is therefore often referred to as the "heart of heating". A modern high-efficiency pump can be installed Save up to € 120 a year.

Heating pumps work about 6,000 hours a year; mainly in winter. They are quiet but powerful consumers of energy. Older pumps with an output of 80 to 100 watts or more cause around 10% of the average power consumption in the household. Hydraulic balancing can also drastically reduce the energy consumption of the old pump.

High-efficiency pumps use 90% less electricity!

In most cases, however, replacing them with a modern high-efficiency pump is the most economical solution: Modern high-efficiency pumps consume 90% less electricity! 15 watts or less are now sufficient for them. Because: modern, regulated pumps adapt their speed to the actual demand, while old pumps always run with the same output.
