Installing a water heater isn’t just about convenience — it’s about safety and efficiency. Mistakes during installation can lead to leaks, electrical hazards, or equipment failure. In this article, we’ll break down what you need to know before installing a water heater to make sure the process goes smoothly and the system performs properly.
1. Choosing the Right Water Heater
First, you need to decide on the type and size of the unit:
- By type: tank (storage) or tankless (on-demand)
- By power source: electric, gas, or hybrid
- By capacity: 30–150+ liters — depending on household size and usage
For most apartments, a 50–100 liter electric storage water heater is sufficient.
2. Preparing the Installation Site
The unit should be installed on a stable wall, near plumbing and electrical connections.
- Avoid mounting on drywall without reinforcement
- Ensure easy access for maintenance and future repairs
- Wall-mounted units should have adequate height from the floor
3. Electrical Requirements
Water heaters are high-power devices and must be installed safely:
- Use a dedicated power line with proper grounding
- Install a circuit breaker and GFCI protection
- Upgrade the wiring if needed, especially for older homes
4. Plumbing and Water Supply
The plumbing setup should ensure consistent pressure and leak-free operation:
- Install a check valve and pressure reducer to protect the system
- Use quality fittings and sealants
- Connect using flexible hoses or metal-plastic piping
5. First Startup Checklist
Before turning the unit on:
- Make sure the tank is completely filled with water
- Inspect all joints and connections for leaks
- Run a test cycle to check temperature, pressure, and performance
