Central heating in Valjevo
A well-designed central heating system warms every room evenly, uses less energy and stays quiet. AQUATIM installs complete heating systems - from the heat source through the distribution to the radiators - and makes sure every part works in harmony.
The system starts at the heat source. We install gas condensing boilers, pellet and solid-fuel boilers, and combined solutions, depending on what you have available and how much you want to spend on fuel. Each boiler comes with a safety group, expansion vessel and a correctly sized circulation pump - without those a system runs, but not the way it should.
Distribution is run to suit the building - copper or multilayer (PEX/AL/PEX) pipe for surface installations, or in-floor routing for new builds. Radiators are sized to each room's heat loss, not by guesswork, and every one gets a thermostatic valve so you can set the temperature room by room. Larger living rooms and bathrooms often need a stronger radiator than people expect.
Once everything is connected we fill, bleed and balance the flow across the branches - so the last radiator in the run heats as well as the first. Only after commissioning and a pressure check do we consider the job finished.

From practice
From practice: in a family house in Mionica we replaced a worn-out wood boiler with a condensing gas boiler and balanced the existing radiators - the heating bill fell and the house now warms evenly across both floors.
How we work
Step 1
Sizing & proposal
We assess heat loss and propose the heat source and radiator layout.
Step 2
Boiler install
We install the boiler with all ancillary equipment and a flue for the combustion products.
Step 3
Pipework & radiators
We run pipe and hang radiators with thermostatic valves for per-room control.
Step 4
Balancing & handover
We fill, bleed and balance the system, then show you how to operate it.
Frequently asked questions
Can you replace just the boiler and keep my radiators?
Yes, if your existing radiators and pipework are sound. Before the swap we check they are sized for the new boiler and, if needed, flush the system so the new pump doesn't pull old sludge.
Why does one radiator stay cold while the rest work?
Usually it's air trapped in the radiator or unbalanced flow. Bleeding and re-balancing the branches normally fixes it; if not, we check the valve for blockage.
Burst pipe, dead boiler, leaking AC?
Call and tell us the problem - you'll know the price before we start. Based in Valjevo, we come to you wherever you are in Serbia.
