Heat substation maintenance, repair and installation
A heat substation controls a building's heating and hot water production and connects district heating to the building's internal piping. If the substation's automation or heat exchanger isn't working correctly, the result is either a cold building or an unreasonably high heating bill.

For apartment buildings and business clients
With a maintenance contract client, we know the site's equipment and history, meaning a faster fix when heat is lost on a cold night. Substation maintenance can be combined with a housing association's general heating system maintenance.
How to recognise a heat substation problem
- The building heats slowly or unevenly across floors
- Hot water temperature is unstable
- The heating bill has risen without reason
- Pump noise or visible leak traces come from the substation
What affects the maintenance scope
Scope is affected by the substation type (residential, commercial or industrial building), the age of the automation, and whether the substation is single- or multi-stage. The price is confirmed before work begins, based on an inspection of the site.
A heat substation isn't the same as an apartment's heating system
The heat substation is a whole-building device: it receives heat from district heating and passes it on to the building's heating and hot water circuits. The client is usually a housing association, management company or building owner, not a single apartment.
If the problem is only in one apartment — one cold radiator, quietly circulating heat — the solution starts with the apartment's heating system or radiators. But if heat is uneven throughout the building or hot water fluctuates, it's worth starting with the substation and its automation settings.
Frequently asked questions
- How often should a heat substation be maintained?
- At least once a year, before the heating season. For higher-load sites, it's worth checking the substation twice a year.
- Do you also maintain smaller commercial premises substations?
- Yes, we service both large apartment building substations and smaller commercial and industrial building solutions.
- Who orders heat substation maintenance in an apartment building?
- Usually the housing association board or the management company responsible for the building's technical systems. An individual apartment owner can call us, but coordinating the work goes through the building's representative.
