Installing a geyser (water heater) requires both plumbing and electrical work. Below is a step-by-step guide to help you understand the process:

Tools and Materials Needed:

Geyser (water heater)

Pipe wrench, adjustable wrench, pliers

Drill and drill bits

Teflon tape, pipe insulation

Plumbing pipes (PVC, copper, or PEX)

Pipe fittings and valves (stop valves, unions, elbows, etc.)

Wall anchors (if mounting the geyser)

Circuit breaker and electrical wiring (for electric geysers)

Safety valve and pressure relief valve


Step-by-Step Installation Process:

1. Choose the Location:

The geyser should be installed in a location close to the point of use to minimize heat loss.

Ensure there is enough space for proper ventilation, especially for gas geysers.

Avoid installing it directly over electrical switches or outlets.


2. Turn Off Water and Electricity:

Shut off the main water supply.

For electric geysers, turn off the power supply at the circuit breaker.


3. Mount the Geyser (if wall-mounted):

Drill holes in the wall and use wall anchors or brackets to securely mount the geyser.

Ensure the geyser is installed at a height that allows easy access to the controls and maintenance.


4. Connect the Plumbing:

Use Teflon tape to wrap the threads of the geyser's inlet and outlet connections.

Connect the cold water inlet pipe to the geyser’s inlet using the appropriate pipe (PVC, copper, or PEX).

Connect the hot water outlet to the appropriate pipe leading to the taps or shower.

Install a pressure relief valve on the hot water line to prevent excessive pressure buildup.


5. Install a Drain Valve (Optional):

You may want to install a drain valve at the bottom of the geyser to make maintenance and cleaning easier.


6. Connect the Electrical Wiring (For Electric Geysers):

Ensure the power is off before working with electrical wiring.

Connect the geyser to the power supply using the correct gauge wire. Ensure the wiring is properly grounded.

Connect the geyser to a dedicated circuit breaker with the correct amperage rating (usually 15-30 amps).

Make sure a thermostat is installed to regulate the temperature.


7. For Gas Geysers (If Applicable):

Connect the gas line to the geyser, ensuring there is a proper shutoff valve for safety.

Install a ventilation system to expel exhaust gases outside the home.


8. Test the Installation:

Turn on the water supply and fill the geyser tank with water.

Open the hot water taps to remove any trapped air from the system.

Turn on the power (for electric geysers) or light the pilot (for gas geysers).

Wait for the water to heat up and check for any leaks in the plumbing or issues with electrical connections.


9. Insulate the Pipes:

For better energy efficiency, insulate the hot water pipes to minimize heat loss.


Safety Considerations:

Pressure Relief Valve: Always install a pressure relief valve to prevent the geyser from exploding due to excessive pressure.

Grounding: Ensure the geyser is properly grounded to avoid electrical hazards.

Thermostat Settings: Set the thermostat to a safe temperature (usually around 120°F or 49°C) to prevent scalding.


Professional Installation:

If you're not experienced with plumbing or electrical work, it's highly recommended to hire a professional to install the geyser to ensure everything is up to code and safe.
