District Heat Transfer Stations - ratiotherm Smart Energy Systems

Innovative network concepts with local heating

ratiotherm specializes in the development of products for the use of cold or sliding heat networks in the field of heat pumps. The idea behind this is to generate fewer network losses by centrally tapping a source and then distributing the heat via a pipe system. The temperature required for drinking water and heating purposes is generated by our specially developed heat pumps. Based on a classic groundwater or brine heat pump, these local heat transfer stations are specially equipped for use in innovative network concepts (Heating Network 4.0). The systems are characterized by the possibility of integrating a classic transfer station for local heating (60-95°C) into the system. We also manufacture special solutions according to customer requirements.

The advantages of the district heating heat pump at a glance:

Significant reduction in grid losses

FAQ: Questions & answers about district heating heat pumps

When is cold local heating worthwhile?

Cold local heating is particularly suitable when heating and cooling requirements occur simultaneously at as many times of the year as possible. This is the case, for example, when residential buildings require hot water (heating) and air conditioning (cooling) in summer.

How much does it cost to connect to the local heating network?

How much does it cost to connect to a local heating network? The cost of connecting to a local heating network or switching from an existing heating solution to local heating can be around $8,000 to $15,000.

Is local heating promoted?

As part of the federal subsidy program for efficient buildings (BEG), grants of 30% to 70% are available if you replace your old heating system with a local or district heating connection. Grants and loans can be applied for through KfW (Kreditanstalt für Wiederaufbau).

How does local heating get into the house?

How does the heat get into the house? Local heat is transported to consumers via a well-insulated pipe system. Water is usually used as the heat transfer medium. The main pipe is usually laid underground along roads and paths.

Is local heating environmentally friendly?

Local heating or district heating is a very climate-friendly way of heating, as CO² emissions are lower than with oil or gas heating. How environmentally friendly the heat actually is depends entirely on the fuels used to operate the heat generation systems.
