Boiler Service and Installation - Vodoinstalater Zagreb

Boiler Service and Installation

Boiler service and installation begin with checking the appliance type, symptoms, and connections. Depending on the findings, work may include descaling, checking the heating element, thermostat, and valve, or recommending replacement. Heating, leak tightness, and safety components are checked after the work.

Benefits of this service

Regular maintenance and descaling can help the boiler operate more consistently and efficiently

Reducing electricity or gas consumption by removing limescale buildup that reduces heating efficiency

Expert installation with proper connection to water supply, drainage, and electrical or gas systems

Replacement of worn parts such as heaters, thermostats, and safety valves before failure occurs

Final checks of heating, connections, and safety components after service

Checking the appliance model and type before arrival to select the appropriate procedure and parts

Common problems we solve

Boiler does not heat water sufficiently or at all — water is lukewarm or cold

Water leaking from the boiler — underneath the unit or from the safety valve

Inconsistent water temperature — sometimes scalding, sometimes cold

Strange noises from the boiler — popping, hissing, or gurgling during heating

Increased electricity consumption without a change in hot water usage habits

How the process works

1

Boiler inspection — checking external condition, connections, and any visible damage or leaks

2

Testing boiler operation — measuring water temperature, pressure, and heating time

3

Descaling the boiler interior and checking the condition of the heater and anode rod

4

Replacing worn parts — heater, thermostat, anode rod, or safety valve as needed

5

Re-testing operation, checking for leaks, and providing maintenance advice

When to call a professional

Water from the boiler is lukewarm or cold even after sufficient heating time

A puddle of water has appeared under the boiler or it drips from the safety valve

The boiler is producing unusual noises you have not heard before

The boiler is over 8 to 10 years old and has never been serviced

Your electricity or gas bill is noticeably higher without a change in habits

Factors that affect the price

Boiler type — electric, gas, tankless, or solar, each requires a different level of expertise

Nature of the problem — simple servicing, part replacement, or complete boiler replacement

Amount of limescale — heavily scaled boilers require more time for cleaning

Boiler location — wall-mounted boiler in an accessible spot or boiler in a tight space under a sloped roof

Brand and model — imported parts for premium boiler brands affect the final price

Work process and service details

Our boiler service and installation service is designed to provide you with maximum efficiency with minimal complication. Before any major intervention, we perform a detailed visual inspection and, if necessary, use modern devices (cameras, thermal and acoustic equipment) to reliably determine the root of the problem in your pipes or household appliances.

Before work begins, the scope, expected costs, and any limitations are explained. Work starts only after you agree to the proposed scope.

Professional equipment and tools

The diagnostic method depends on the problem: a visual inspection may be enough, while hidden leaks can require camera, thermal, or acoustic measurements. The aim is to narrow the affected area before invasive work.
