Costly building alterations
A ground-source borehole, a district heating connection or extensive alterations can make replacing your heating expensive. We assess another option for your building.
Server heating for existing and new buildings
Heat from
computing power.
Need to replace your heating, but a heat pump or district heating is not an option? DecentralHeat uses the heat from liquid-cooled high-performance computers for space heating and hot water. The computing power generates revenue that can help cover your running costs. We take care of the technology and operation.

Where we fit
When replacing your heating gets complicated.
For homes, hotels, commercial premises and public buildings. Particularly worth considering where conventional solutions face constraints at the site.
Limited options at the site
A lack of outdoor space, unsuitable ground or high heating temperatures can complicate planning. A server heating system is installed in a suitable plant room.
Specific restrictions
Listed buildings or restrictions on structural alterations can make a different approach worthwhile. Permission is assessed for each project with the relevant authorities and specialists.
How it works
One electricity supply. Two benefits.
High-performance computers do computing work and generate heat for your building. That computing work can generate revenue: the Compute Return. Revenue allocation is agreed contractually for each project. Depending on the agreement, it can help cover your running costs. Your heat demand determines how much the system runs.

Heat demand controls the computing load.
01 · Compute
Liquid-cooled high-performance computers provide computing power and generate heat. Their output adjusts to the heat demand.
02 · Transfer heat
A separate primary circuit and a plate heat exchanger transfer the heat to your water-based heating system and hot water supply.
03 · Benefit from Compute Return
Revenue from the computing power is allocated according to the agreement for each project. Depending on that agreement, Compute Return can help cover your running costs. The amount depends on the market and operation and is not guaranteed.
Three models
Start compact. Expand in modules.
DH-5 for small applications and supplementary heating. DH-50 and DH-150 are modular from 20 kW. Heat load, heating temperature and electrical capacity determine the choice.
up to 5 kW
DH-5
The compact server heating system with 5 kW heat output. Particularly suited to supplementary heating in single-family homes, tiny houses, pool heating and small businesses.
Explore DH-5
20-50 kW
DH-50
The DH-50 delivers up to 50 kW of heat, modular in 10 kW steps from 20 to 50 kW. It is suited to building heating and smaller commercial properties and integrates into existing heating systems.
Explore DH-50 / DH-150
20-150 kW
DH-150
The DH-150 delivers up to 150 kW of heat, modular in 10 kW steps from 20 to 150 kW. Typical uses include apartment buildings, hotels, neighbourhood schemes, indoor pools, commerce and agriculture.
Explore DH-50 / DH-150Three models, one principle. The choice depends on your heat load, required temperature and electrical connection. The maximum and guide values below come from the August 2026 flyers; they do not replace a design tailored to your project.
The three models comparedA starting point
Could server heating work for your building?
These five points give you an initial guide. We can work through anything you do not yet know together during the initial assessment.
Start Quickcheck- 01
Water-based heating
If your building uses radiators or underfloor heating, it already meets an important requirement. A heat storage tank is usually useful too.
- 02
Suitable for existing radiators too
Flow temperatures up to 85 °C according to the datasheet. The temperature that is achievable and appropriate for your building depends on the hydraulics and operating conditions.
- 03
The right electrical connection
The larger the system, the more electrical capacity it needs. We check together whether your existing connection is sufficient.
- 04
Enough space
The system is installed in a boiler or plant room. We check which model fits and how it can be brought into position.
- 05
Internet for remote support
A stable internet connection enables remote monitoring, so operation can be supported and checked remotely.
Questions
Frequently asked questions.
What you may want to know before deciding: suitability, operation, costs and next steps.
All questionsDoes it fully replace my oil or gas heating?
That depends on the building and its heat demand. Server heating can fully replace the existing heating or work alongside it. In a combined system, the second heat source can provide extra heat on very cold days, for example. It can also act as a backup if one system is temporarily unavailable. For larger projects, several DecentralHeat units can be designed to provide reserve capacity. We assess the options based on past consumption, the required heating temperature, existing equipment and the desired level of reliability.
What happens in summer when no heat is needed?
The system is designed for continuous operation, but runs according to heat demand. If the building needs no heat, it switches off.
What does the system cost?
The purchase price, integration and service are quoted for each project. There are also ongoing electricity and maintenance costs. After your enquiry, we discuss heat load, existing equipment and the site. We then clarify planning requirements and any site visit needed to prepare an offer. We do not promise a fixed saving or payback period.
What happens after I enquire?
