4th Generation District Heating

The future district heating system is called 4th Generation District Heating or 4GDH. Our new generation systems offer several improvements and opportunities through smart control systems, ability to use new energy sources and two-way district heating.

The main district heating projects in the future will concentrate in recovery and use of waste heat. A plant generating a lot of waste heat will be able to use the excess heat in heating the property. In addition, it can be sold to the district heating network to be used in heating the neighbourhood houses. Naturally the same technology is available for residential properties, which can also recover heat and barter it in the network.

New innovations for better heating

We have long experience in manufacturing and selling high quality district heating solutions. During this time, we have constantly developed our company and products.

We have upgraded our reliable, high-quality Unis and GST substations to the next generation as well as introducing new, energy efficient innovations.

FiksuGST is a fourth-generation district heating substation, which is equipped with an intelligent Fiksu Control System. The remotely controlled system enables close monitoring of the whole heating system and its optimization.

FiksuGST’s sister model, HybridREADY, offers an option to upgrade the heating system to a hybrid system later. HybridREADY is also equipped with a smart control system.

Adding smart features to district heating equipment is just one way of improving the efficiency of district heating. New innovations to e.g., heat transfer technology can also boost efficiency and bring down heating costs and emissions.

Control is everything

The whole system works efficiently under intelligent control system. Our versatile Fiksu Control System offers advanced monitoring, IoT applications and artificial intelligence to provide comprehensive information on the operation of the property’s entire heating system.

The utilization of the collected data benefits the entire district heating system. For example, property-specific data enables the power plant to estimate consumption peaks, thus making production more predictable. A fourth-generation district heating substation is no longer just a heating but also a data substation.

Simply put, 4GDH is a more flexible, open and environmentally friendly way of heating than its predecessors.

Mid-Cooling Connection improves efficiency

3-step Mid-Cooling Connection (MCC) is a groundbreaking innovation developed by HögforsGST. The new connection improves district heating’s efficiency and Delta T by circulating the hot supply water first through the domestic hot water heat exchanger, then through the heating circuit, and then through the domestic hot water heat exchanger. This three-step process ensures that the energy in the district heating network is discharged to the building as efficiently as possible

Hybrid heating offers flexibility

The range of individual properties’ heating solutions is more flexible than ever. Current technology allows us to utilize of multiple heat sources alongside of district heating. These are called hybrid systems.

Hybrid heating can be compared to a hybrid vehicle. Like a car that switches between different energy sources according to need, a heating system can choose between district heating and a heat pump, for example. Our factory tested HybridHEAT system is an excellent option for any property looking for an easy upgrade to their heating system.
