Modern systems are frequently used by builders and homeowners seeking balanced, effective heating solutions. The Tichelman loop, also referred to as the associated heating system, is one example of such a system. The capacity of this technique to provide uniform and even heating throughout a property makes it stand out.
A special kind of heating system design known as the Tichelman loop makes sure that every radiator or heating element gets the same quantity of hot water, which results in even heat distribution. In contrast to conventional systems, which may have trouble providing enough heat to radiators located further away from the boiler, the Tichelman loop solves this problem with its ingenious plumbing design.
The supply and return pipes of the Tichelman loop run in parallel, allowing for a balanced water flow through a number of radiators. This design makes sure that every radiator heats up uniformly and reduces temperature dips. As a result, the heating environment is more efficient and comfortable, using less energy and giving you better control over the temperature inside.
Comprehending the fundamentals and advantages of the Tichelman loop can assist you in making well-informed decisions regarding your heating system. Discovering the benefits of this cutting-edge system can revolutionize the comfort and energy efficiency of your house, regardless of whether you’re thinking about upgrading or installing it from scratch.

What is the Tichelman Loop
A dead-end heating system, in its traditional form, is one in which the boiler receives the already-cooled water returning from the radiator through one pipe (the supply), and the radiator receives the hot water entering through another (the return). As a result, this type of system is known as two-pipe. However, a third pipe is occasionally added to two.
It’s true that a one-pipe system can also be a dead end. But putting it into practice is really challenging. Furthermore, installation errors typically result in a significant reduction in heating efficiency. As a result, it is only employed in dire circumstances where there is no other option. Additionally, knowledgeable artisans install it.
The design is also known as the Tichelman loop in heating because of the way the coolant flows through the pipes. Additionally, this can be utilized because the coolant in the return is still just cooling and producing heat. The reverse flow of water is typically linked to pool and underfloor heating systems.
When there are a lot of radiators, a dead-end circuit with a circulation pump is typically utilized. That is when it works best. However, a lot of homeowners install overhead wiring for natural water flow because they want to be energy independent. The figure below depicts one of the schemes.
The system is split into two branches because there are a lot of batteries. Better circulation is encouraged by this. Additionally, a circulation pump is required if all 11 batteries are connected to a single circuit.
Types of dead-end systems
You can have a vertical two-pipe dead-end heating system. In this instance, a riser that is vertically positioned and originates from the boiler penetrates the levels of a multi-story building. Additionally, each floor already has batteries attached to it.
However, the radiator loses heat as it gets farther away from the riser. due to a drop in the coolant circulation rate. As a result, it turns out that the room after this one will be cooler than the one with the main line.
It is thought that the Tichelman system is still economical in a two-story home. Furthermore, if the building has multiple stories, a pump is already necessary. As a result, horizontal design makes more sense. It is, after all, much simpler to connect the heating device to the forward and return pipelines. Considering that the lines correspond to the pipe and connecting element dimensions.
Advantages and disadvantages
Hydraulic-wise, the associated heating system is regarded as the best. The network as a whole is extremely well balanced because the water travels the same distance from each radiator. However, it is far more difficult to calculate and install than a dead end. Furthermore, the project’s implementation will be far more expensive.
A private home’s dead-end heating system can be computed quite easily. in particular, the horizontal version. Its installation will require fewer materials. Furthermore, any homeowner who is capable of handling a tool can complete the task by themselves.
The following are the principal benefits of heating using the Tichelman scheme:
- Versatility of use.
- Possibility to use a smaller pipe diameter for the main line.
- Excellent system efficiency.
- Possibility of adjusting the heating of the battery in each room.
- Easy to calculate and lay out the circuit.
- Possibility to use return for heated floors.
There are only two significant flaws in the system. The heating of the pipeline is a little delayed if a lot of radiators are connected to it. The battery may also experience stagnant zones. This is because the coolant’s natural speed decreases over the pipeline’s lengthy length.
These are very simple problems to solve. Creating distinct branches within the system is sufficient. The circuit must be calculated so that there are no more than six radiators in any one branch. After that, a pump won’t be needed to assist with the coolant flow.
The definition of a dead-end heating system (Tichelman Loop) is given in the video.
My installation recommendations
I’ll skip over the widely accepted guidelines for performing plumbing work. It is true that they vary based on the pipe material selected. But there are a few things you should pay close attention to in order to avoid making mistakes and paying more for adjustments.
The following designations are typically found on the drawings: DN15 or DU15. This is how experts mark the pipe’s internal diameters. They are the ones from whom the entire plan is derived. If the designation Ø26×3 is discovered, the pipe’s outer diameter and wall thickness are indicated by the first and second numbers, respectively.
The coolant may simultaneously come to a dead stop along multiple branches. If the home adopts a similar plan, an adjustable shut-off valve is mounted on the radiator at the end of each line. It is imperative to choose taps with a fitting that allows the system to partially empty of water.
Which type of system you install—a pumping system or a gravity system—is irrelevant. The pipeline slope needs to be maintained in each of them. Two millimeters per linear meter suffice in the first scenario. The slope ought to be 5 mm in the second, at the same interval.
Remember that there are various models of radiator thermostats if you use one. Under natural gravity, higher throughput products are produced. You risk losing your natural circulation if you make the incorrect decision.
And finally, some guidance. When laying a line from the penultimate radiator to the dead end, use the pipes with the smallest diameter. You must pay attention to the people who are on the front lines.
The following video will demonstrate how to accurately compute heating using the Tichelman scheme:
The reverse return system, sometimes referred to as the Tichelman loop, provides an incredibly effective means of heating your house. It ends the common problem of uneven heating by making sure that each radiator receives an equal amount of water. Because of this, it’s a great option for both big and small heating systems, giving the entire room a constant warmth.
The Tichelman loop’s ease of use in system balancing is one of its main advantages. In contrast to conventional configurations where each radiator needs to be precisely adjusted, the Tichelman loop self-balances. This lessens the need for continuous maintenance in addition to saving time and effort during installation.
The potential for energy savings is an additional benefit. The system keeps all radiators at the same temperature, so your boiler doesn’t have to work as hard to make up for cold spots. This may result in less energy being used, which would lower heating costs.
The efficiency and dependability of your heating system can be greatly increased by incorporating the Tichelman loop into your design. This approach offers a reliable solution that can be tailored to meet different heating requirements, regardless of whether you’re planning a new installation or upgrading an old one. For contemporary heating systems, the Tichelman loop is a wise option due to its simple implementation and demonstrated efficacy.
The reverse return system, commonly referred to as the Tichelman loop, is a very effective heating system design that is perfect for guaranteeing even heat distribution throughout buildings. Because of this design, pressure differentials in the system are reduced and all radiators can heat evenly. The Tichelman loop enhances the overall performance and energy efficiency of the heating system while making installation and maintenance easier by looping the supply and return lines in the opposite directions.
