HEATING REPLACEMENT & MODERNISATION
Heating replacement and modernisation from Berlin-Lichtenrade
Would you like to replace your heating system? TK SHK supports heating replacement and modernisation in Berlin and Brandenburg – from assessing the existing setup to commissioning. For houses, apartment buildings and commercial premises.

New equipment needs to work with the existing installation. We clarify which parts can be retained and what work your project requires – from replacing a single heat source to modernising central heating plant.
To get started, tell us the building type, location, existing system and preferred timeframe. Photos of the equipment, rating plate and plant room help with the initial discussion.
Heat demand, heat emitters, hot water and available space determine the solution. We define the scope of replacement, connections and other work, and clarify interfaces with other trades.
The installation sequence, necessary interruptions and commissioning are agreed for each project. The relevant checks, documentation and an introduction to using the system are included in the work carried out.
An air-to-water heat pump must suit the building. We consider heat emitters, hot water demand and the installation location together, for new builds and heating upgrades in Berlin and Brandenburg.
Existing radiators or underfloor heating are included in the planning. The key factors are how much heat the rooms need and how it is distributed.
The outdoor unit, storage tank and pipe routes need a suitable installation space. We consider space, sound and hot water demand together.
We coordinate the controls with the heat distribution and explain how to use them. On request, we consider app control, schedules and smart home features, depending on the equipment and system.

Radiators and underfloor heating are essential parts of your system. We consider the right heat emitters alongside your existing pipework.
Replacement, connection and testing, tailored to the room, building and planned heating system.
Underfloor heating for new builds and renovations. The construction and installation are planned around your building.
Heat emitters, pipes and the heat source need to work together. We assess the whole heating system and agree the scope of the upgrade.

Would you like to replace your heating system or keep and modernise suitable components? Describe whether the work concerns the heat source, radiators, hot water provision or heat distribution. We coordinate the scope for private homes, apartment buildings and commercial properties.
Your heating technology, heated floor area and desired result are helpful starting points. For several radiators, please state the number and rooms. Costs and scheduling depend on equipment selection, pipe modifications, removal and access. For communal heating, we involve owners, property management and occupants in the coordination. We clarify which work belongs together and which components can remain before preparing a quotation. We coordinate your preferred timeframe with material availability and installation conditions.

Good to know
Photos of the system, rating plate and plant room help us make an initial assessment. For a reliable quotation, we also need to clarify connections, available space and the scope of work you require. After your enquiry, we will discuss which documents or site visit are needed.
That depends on the rooms’ heat demand, the existing heat emitters and the required system temperatures. We check the existing system and include suitable components in the planning. We do not assume that all radiators need replacing.
Interruptions may be needed during replacement. Their duration and timing depend on the system and the scope of work. We clarify this before installation; for apartment buildings, this includes access arrangements and coordination with property managers and occupants.
Yes. We modernise central heating plant, central hot water systems and heat distribution. The number of homes, information about the existing system and any available plans help us prepare. More about projects for property managers and owners’ associations.
Room size, required heat output and existing connections need to suit the planned system. Tell us the number of radiators and the location. If the heat source is being replaced at the same time, we coordinate both measures.
Yes. For gas boiler replacement, we consider the existing appliance, connections, flue system and hot water supply. We clarify which solution and adjustments are suitable for your building on a project-by-project basis. Read more about replacing a gas boiler.
Tell us the building type, approximate living area, location and postcode, existing heating system and the change you would like to make. The system’s age, manufacturer and model, plus annual energy consumption if known, help us prepare. For a heat pump, details of radiators or underfloor heating and photos of the plant room and proposed installation location are useful. We use this information and an assessment of the installation space to clarify the appropriate equipment, scope of work and an individual quotation.

Modern heating technology





Replacing a radiator is more than just swapping a visible component. Connections, mounting, spatial conditions, and required heat output must be compatible. We examine the existing installation and tailor the new solution to the room and heating system. This results in an implementation that integrates technically and visually into the building.

Careful planning considers the room layout, connection positions and future use. It provides the basis for a suitable heating solution and coordinated installation.




A floor heating system later disappears beneath the finished floor – but its planning remains decisive. Pipe routing, available installation height, and supply of individual rooms must be considered early. The visible installation is therefore only part of a carefully prepared heat distribution.



At the heating circuit distributor, the individual circuits of a surface heating system converge. Flow indicators and control components clearly show that comfortable heat requires coordinated distribution. We consider the design and adjustment in connection with the rooms, the heating surfaces, and the entire system.

Translated from German
“I had my old gas boiler replaced with a new combi boiler and I am really happy. An appointment was arranged quickly and installation went smoothly. The old boiler was removed and the new one installed straight away. The heating and hot water work perfectly again, and everything was left clean. The price was also as discussed beforehand. I can definitely recommend them 👍”
