7 Mistakes to Avoid During Water Heater Installation

Installing a water heater correctly is a crucial task that requires attention to detail and precision. Mistakes during installation can lead to inefficiency, safety hazards, and even costly repairs. Here are seven common mistakes to avoid for smooth water heater installation.

1. Ignoring Local Building Codes:

One of the biggest mistakes during water heater installation is disregarding local building codes and regulations. Each region may have specific requirements regarding water heaters' placement, venting, and safety measures. Ignoring these codes can result in failed inspections, fines, or legal issues. 

Before starting the installation, thoroughly research and comply with the local building codes to ensure the installation is done correctly and safely.

2. Improper Sizing:

Choosing the wrong water heater size is a common mistake that can lead to inefficiency and increased energy costs. Installing a water heater that is too small for the household's needs will result in insufficient hot water supply, especially during peak demand periods. 

On the other hand, installing a water heater that is too large can lead to unnecessary energy consumption. Properly sizing the water heater based on the household's hot water demand is crucial to ensure optimal performance and energy efficiency.

3. Neglecting Ventilation Requirements:

Proper ventilation is essential for safe operation and efficient performance of water heaters. Neglecting ventilation requirements can lead to carbon monoxide buildup, fire hazards, and poor indoor air quality. 

Ensure that the water heater installation is done in a well-ventilated area and follow the manufacturer's guidelines for venting specifications. It's also important to regularly inspect and maintain the vents to prevent blockages and ensure proper airflow.

4. Incorrect Pressure Relief Valve Installation:

The pressure relief valve (PRV) is a critical safety component of a water heater, as it helps prevent excessive pressure buildup inside the tank. Improper setting up of PRV in water heater installation can compromise its functionality and pose a safety risk. 

Ensure that the PRV is installed correctly according to the manufacturer's instructions, with proper piping to direct the discharge away from the heater and safely to the floor or drain. Additionally, test the PRV after installation to verify its correct operation.

5. Skipping Insulation:

Insulating the water heater and hot water pipes is often neglected during installation, but it can greatly improve energy efficiency and reduce heat loss. 

Without proper insulation, the water heater must work harder to maintain the desired temperature, leading to increased energy consumption and higher utility bills. Install insulation blankets on the water heater and insulate the hot water pipes to minimize heat loss and improve overall efficiency.

6. Forgetting to Flush the Tank:

Before installing a new water heater, it's essential to flush the tank to remove any sediment or debris that may have accumulated inside. Neglecting this step in water heater installation can lead to reduced efficiency, diminished performance, and even premature device failure. 

Follow the manufacturer's instructions to properly flush the tank and ensure it is clean before installation. Flushing the tank will help prolong the water heater's lifespan and maintain optimal performance.

7. Not Hiring a Professional:

Attempting a DIY water heater installation without the necessary knowledge, skills, and tools can result in costly mistakes and safety hazards. While DIY installation may seem like a cost-saving option, hiring a professional plumber or HVAC technician is often best. 

A qualified installer will ensure that the water heater is installed correctly, according to local codes and manufacturer guidelines, minimizing the risk of errors and providing safe and efficient operation.
