With water heaters, the same symptom can have different causes. A lack of hot water may be related to the heating element, the thermostat, the thermal protection, the electrical supply or another part of the system.
In case of a leak, it is important first to establish where the water is coming from. A leak around the flange or the connections is a different problem from a leak related to the tank itself. That is why every repair starts with diagnostics.
The technician checks the components related to the specific symptom, and you receive information about the fault found and the recommended repair. When the fault allows it, the repair is carried out at your address. You can also read RotoRem customer reviews.

I am very pleased with Rosen. Even though his schedule was full, he managed to come and repair the water heater. I called him in the morning and after lunch between 15.20 and 16.20 he bought and replaced 2 radiators. The water heater works perfectly.

Water Heater Faults We Repair
Water heater does not heat the water
When the water heater has power but the water stays cold, we can check the heating element, the thermostat, the thermal protection and the electrical connections. A burnt-out heating element is one of the possible causes, but it should not automatically be assumed that it must be replaced.
Water heater heats the water weakly
If the water warms up but does not reach the normal temperature, or heating takes significantly longer, the cause may be related to the heating element, the temperature control or build-up around the heating element. Before any repair, the specific condition of the appliance is checked.
Water heater trips the circuit breaker
If the circuit breaker or protection trips when the water heater is switched on or while it is heating, the water heater must be inspected before it is used again. The cause may be the heating element, an electrical leakage, a wiring connection or another electrical component.
Water heater leaks
First, it must be established where the water is coming from. The leak may be around the flange, the gasket, the safety valve, the water connections or another part of the water heater. If the problem is related to the tank itself, the technician must judge whether the repair is technically and economically justified.
Leak around the flange
The flange gives access to the heating element and other internal components. In case of a leak around it, the gasket, the fastening, the condition of the flange and the contact surface must be checked. It is not enough to simply tighten it without finding the cause.
Safety valve releases water
A certain amount of water from the safety valve during heating may be related to the normal rise in pressure, but constant or unusual discharge should be checked. It should not automatically be assumed that the valve is faulty – the conditions under which the leak appears need to be examined.
Water heater overheats the water
If the water becomes unusually hot or the water heater does not stop heating normally, the temperature control system must be checked. Possible causes include the thermostat, the thermal protection or another control component.
Water heater switches off before the water is hot
Switching off too early may be related to the temperature control, the thermal protection, the heating element or another fault. Diagnostics need to establish at which point heating is interrupted and how the appliance reacts afterwards.
Water heater heats very slowly
A longer heating time may be related to the heating element, its power rating, build-up around it or another problem in the system. In older water heaters, the condition of the internal components must also be assessed.
Water heater does not turn on
When there is no indication and heating does not start at all, we can check the power supply, the electrical connections, the thermal protection, the thermostat and the other components in the circuit.
Water heater makes unusual noise
Noise during heating may be related to build-up around the heating element or to other conditions inside the water heater. The noise alone is not enough to determine the cause and must be considered together with the other symptoms.
Water Heater Diagnostics in Varna
Diagnostics aim to establish the cause of the problem before any components are replaced.
Depending on the symptom, we may check:
- the heating element;
- the thermostat;
- the thermal protection;
- electrical connections;
- the power cable;
- the flange;
- the gasket;
- the safety valve;
- the water inlet and outlet connections;
- the presence of a leak;
- the condition around the heating element;
- limescale build-up;
- anode protection, where the construction allows it;
- the overall condition of the water heater.
After the inspection, you receive information about what was found and what repair is recommended.

| Part or system | Commonly related problem |
|---|---|
| Heating element | Water does not heat / heats slowly |
| Thermostat | Incorrect temperature |
| Thermal protection | Water heater cuts out or does not start |
| Flange | Leak at the bottom |

Important: the same symptom can be caused by different components. The exact repair and the required parts are determined after diagnostics.
Water Heater Heating Element Replacement
The heating element converts electrical energy into heat and is one of the main components of an electric water heater.
When it fails, symptoms may include cold water, insufficient heating, the protection tripping or the heating cycle being interrupted.
Before replacement, the heating element must be tested, because similar symptoms can also be caused by the thermostat, the thermal protection or an electrical fault. When a replacement is needed, a component suitable for the specific model is used.
Thermostat and Thermal Protection
The thermostat takes part in controlling the water temperature, and the protective components play an important role in the safe operation of the appliance.
When there is a problem, the water heater may not heat, may cut out too early, may overheat or may not restart after the protection has tripped. Before replacement, we check which component is causing the specific behavior.
Water Heater Leaks
Not all leaks have the same cause or the same repair. It is important to establish whether the water is coming from a connection, a valve, the flange, the gasket or the tank itself.
In case of a leak around the flange, it may be necessary to check the gasket and the condition of the related components. If there is a suspected problem with the tank itself, it must be assessed whether a repair is reasonable.
Water Heater Descaling (Limescale Removal)
Over time, mineral deposits can build up on the heating element and other internal parts. The amount depends on the operating conditions, the water and the period of use.
When the water heater is opened, the technician can assess the condition of the heating element and the presence of build-up. Cleaning is carried out when it is necessary and suitable for the specific appliance.
Water Heater Anode Protection
In water heaters with a magnesium anode, the anode protects the tank against corrosion. Its condition can be checked during suitable maintenance or when the water heater is opened for another repair.
No universal replacement interval is set without taking into account the model, the manufacturer's instructions and the operating conditions.
Water Heater Installation and Removal
Water heater installation
When installing a new electric water heater, the following may be carried out:
- positioning and suitable mounting;
- checking the water connections;
- installing or checking the safety valve;
- connection according to the specific installation;
- filling and checking for leaks;
- a test run of the appliance.
Removal of an old water heater
When the appliance is being replaced, the old water heater can be switched off, drained, disconnected from the water connections and safely taken down.
Types of Water Heaters We Service
Vertical water heaters
One of the most common types for the home. The repair depends on the construction, the capacity and the specific fault.
Horizontal water heaters
The layout of the components and the way they are mounted can differ from vertical models.
Compact water heaters
Models for under-sink installation. Diagnostics are carried out according to the specific model and access to the components.
