Upgrading to a tankless water heater is a smart investment for homeowners looking for energy efficiency, endless hot water, and space savings. But before making the switch, it’s essential to understand the installation process, requirements, and what to expect. Proper installation ensures optimal performance, longevity, and energy savings.
In this guide, we’ll walk you through everything you need to know about installing a tankless water heater, from preparation to post-installation maintenance.
Why Choose a Tankless Water Heater?
Unlike traditional water heaters that continuously heat a large tank of water, tankless water heaters provide hot water on demand. This means:
✅ No more running out of hot water – Perfect for large families and high-demand households.
✅ Lower energy bills – No standby heat loss, making them 30-50% more efficient than storage tanks.
✅ Space-saving design – Wall-mounted units free up valuable floor space.
✅ Longer lifespan – With proper maintenance, tankless water heaters last 20+ years, compared to 10-15 years for traditional models.
But to enjoy these benefits, professional installation is key. Let’s break down the process.
Step 1: Evaluating Your Home’s Compatibility
Before installing a tankless water heater, a professional will assess your home’s existing plumbing, gas, and electrical systems to ensure compatibility. Here are key factors to consider:
- Fuel Type: Tankless water heaters are available in gas and electric models. Gas units require proper ventilation, while electric models need dedicated circuits.
- Water Demand: The size and flow rate (GPM) of your unit should match your household’s hot water needs. A professional assessment helps determine the right capacity.
- Location & Space: Tankless units are compact but require strategic placement for efficiency and accessibility.
- Water Pressure: Most tankless systems operate best within a 30-80 psi pressure range. A pressure regulator may be needed if your home’s water pressure is too high or too low.
If any upgrades or modifications are necessary, your installer will discuss them before moving forward.
Step 2: Preparing for Installation
Once the assessment is complete, pre-installation preparation begins. This may involve:
🔹 Upgrading Gas Lines or Electrical Wiring – Some homes need a larger gas line or a dedicated electrical circuit to support the tankless unit.
🔹 Installing Proper Venting – Gas-powered models require a ventilation system to safely expel exhaust gases.
🔹 Shutting Off Water & Power – Before installation, the old system is drained and disconnected.
Your technician will ensure all permits and codes are met before proceeding with installation.
Step 3: Installing the Tankless Water Heater
The installation process typically takes 4-8 hours and includes:
1️⃣ Mounting the Unit – The compact water heater is installed on a wall, usually near the existing plumbing and power sources.
2️⃣ Connecting Water Lines – New cold and hot water lines are connected to ensure proper water flow.
3️⃣ Fuel Source Connection – Whether gas or electric, the system is connected safely and tested for leaks or electrical issues.
4️⃣ Setting Up Ventilation – If required, exhaust vents are installed to direct gases outside.
5️⃣ System Testing & Calibration – Once installed, the unit is tested to ensure it delivers hot water efficiently and meets demand.
A professional installer will fine-tune settings for maximum energy efficiency and optimal performance based on your home’s specific needs.
Step 4: Post-Installation Tips & Maintenance
Once your tankless water heater is installed, follow these maintenance tips to keep it running efficiently:
✔ Flush the System Annually – Mineral buildup from hard water can reduce efficiency. A yearly descaling flush keeps the unit in top shape.
✔ Clean or Replace the Filter – Many models have inline water filters that need periodic cleaning.
✔ Check for Error Codes – Most units have digital displays that notify you of maintenance needs.
✔ Monitor Venting (For Gas Models) – Keep exhaust vents clear of debris to ensure proper airflow and safety.
✔ Schedule Professional Inspections – A licensed technician can identify early signs of wear and perform preventive maintenance.
By following these simple maintenance steps, your tankless water heater can last over two decades while keeping energy costs low.
