Almost 90 percent of all heating systems can be optimised comparatively inexpensively - with the help of hydronic balancing. Stadtwerke Gießen informed customers about what is behind this at a presentation in Pohlheim Watzenborn-Steinberg.
Giessen. Despite the heating valve being fully open, the living room remains cold in winter. At the same time, the radiator in the next room is glowing. If this sounds familiar, you shouldn't wait until winter, but ideally take action during the warm season. But what causes the big temperature difference and what can be done about it? Stadtwerke Gießen (SWG) explained this at a presentation in Pohlheim Watzenborn-Steinberg on 16 June.
"Many heating systems are not optimised for the respective building. The result: pressure differences occur in the pipework. Hot water from the boiler therefore does not flow evenly wherever it is supposed to go," explained SWG energy consultant Martin Lorenz during his presentation. He pointed out that the pressure differences can be rectified comparatively easily and cheaply - with the help of hydronic balancing.
Reduce energy costs - quickly and easily
Martin Lorenz pointed out that an incorrectly set heating system often leads to significantly higher energy consumption. This is because if some radiators remain cold, in many cases the flow temperature of the system is turned up. Costs rise and comfort suffers.
With hydronic balancing, however, the installers adjust the flow rate of the heating water in each heat exchanger - radiators or underfloor heating - to the heating requirements of all rooms. To do this, they adjust the respective flow rate according to their calculations - using pre-settable valves. These make it possible to precisely determine the flow rate in the radiator - i.e. how much water flows through the radiator per unit of time. Energy savings of around 15 per cent are possible as a result. In particular, heating systems with condensing boilers, which already work efficiently, can be further optimised with the help of hydronic balancing.
SWG offers hydronic balancing together with the Giessen Guild for Sanitary, Heating and Air Conditioning Technology - as part of the "enerGIeßen" service package.
"As a contact partner, we provide information at our customer centre and select a partner installer together with the customer," explained Martin Lorenz. The relevant guild company then records all the necessary data on the heating system at the customer's home and passes it on to the experts at SWG. During a further appointment at the customer centre, the consultants discuss how the existing system can be improved by means of hydronic balancing and draw up an offer to optimise the heating system at a fixed price. Once the customer has placed the order, the installers get to work. In a typical detached house with six rooms, the specialist company only needs a short time to install the pre-settable valves. Customers also receive a comprehensive inspection report on heat generation, heat distribution and heat transfer in their building - equivalent to the Heating CheckPlus. This service can subsequently help to realise further savings potential.
SWG can also provide information about hydronic balancing by telephone on the service number 0800 23 02 100 or in person at the SWG customer centre on the market square in Giessen. Opening hours: Monday to Friday 9 am to 6 pm and Saturday 9 am to 2 pm.
