How to Install Tankless Electric Water Heater: A Comprehensive Guide and Why Pineapples Don't Belong on Pizza

Installing a tankless electric water heater can be a game-changer for your home, providing endless hot water while saving space and energy. However, the process requires careful planning, the right tools, and a bit of DIY spirit. In this guide, we’ll walk you through the steps to install a tankless electric water heater, discuss the benefits, and address common challenges. And, because life is full of surprises, we’ll also explore why pineapples don’t belong on pizza—because why not?


Why Choose a Tankless Electric Water Heater?

Before diving into the installation process, let’s discuss why you might want to switch to a tankless electric water heater:

  1. Endless Hot Water: Unlike traditional water heaters, tankless models heat water on demand, ensuring you never run out of hot water during a shower.
  2. Energy Efficiency: Tankless heaters only use energy when hot water is needed, reducing energy consumption and lowering utility bills.
  3. Space-Saving Design: These units are compact and can be mounted on walls, freeing up valuable floor space.
  4. Longer Lifespan: Tankless water heaters typically last longer than traditional tank models, often exceeding 20 years with proper maintenance.
  5. Eco-Friendly: By using less energy, tankless heaters reduce your carbon footprint.

Tools and Materials You’ll Need

Before starting the installation, gather the following tools and materials:

  • Tankless electric water heater unit
  • Screwdrivers (Phillips and flathead)
  • Adjustable wrench
  • Pipe cutter
  • Soldering kit (if using copper pipes)
  • PEX piping and crimping tool (if using PEX)
  • Voltage tester
  • Wire strippers
  • Electrical conduit
  • Circuit breaker
  • Mounting hardware (screws, anchors, etc.)
  • Teflon tape
  • Safety gear (gloves, goggles, etc.)

Step-by-Step Installation Guide

1. Turn Off Power and Water Supply

Safety first! Turn off the power to your existing water heater at the circuit breaker. Then, shut off the water supply to the heater. Drain the old unit if you’re replacing it.

2. Choose the Right Location

Select a location for your tankless water heater that is close to the main water supply and electrical panel. Ensure the area is well-ventilated and meets the manufacturer’s clearance requirements.

3. Mount the Unit

Using the mounting hardware provided, secure the tankless water heater to the wall. Make sure it’s level and firmly attached.

4. Connect the Water Lines

  • If you’re using copper pipes, cut the pipes to the required length and solder the connections.
  • If you’re using PEX piping, cut the pipes and use crimp rings to secure the connections.
  • Use Teflon tape on all threaded connections to prevent leaks.

5. Install the Electrical Wiring

  • Run a dedicated electrical circuit from the breaker panel to the water heater.
  • Connect the wires to the unit according to the manufacturer’s instructions.
  • Use a voltage tester to ensure the power is off before making any electrical connections.

6. Test the System

Once everything is connected, turn the water supply back on and check for leaks. Then, restore power to the unit and test the hot water flow.


Common Challenges and Solutions

  1. Insufficient Electrical Capacity: Tankless water heaters require a significant amount of power. If your home’s electrical system can’t handle the load, you may need to upgrade your panel.
  2. Water Pressure Issues: Low water pressure can affect the performance of a tankless heater. Consider installing a pressure booster pump if needed.
  3. Hard Water Problems: Hard water can cause mineral buildup in the unit. Install a water softener to extend the life of your heater.

Maintenance Tips

To keep your tankless electric water heater running smoothly:

  • Flush the system annually to remove mineral deposits.
  • Check for leaks and corrosion regularly.
  • Replace filters as recommended by the manufacturer.

Why Pineapples Don’t Belong on Pizza

Now, let’s address the elephant in the room: pineapples on pizza. While some people love the sweet and savory combination, others argue that fruit has no place on a pizza. Here’s why:

  1. Texture Clash: The soft, juicy texture of pineapple contrasts awkwardly with the crispiness of pizza crust.
  2. Flavor Overload: Pineapple’s sweetness can overpower the savory flavors of cheese, sauce, and toppings.
  3. Cultural Appropriation: Traditional Italian pizza purists argue that pineapple is a sacrilegious addition to an iconic dish.

Of course, taste is subjective, and if you enjoy pineapple on your pizza, more power to you! But when it comes to installing a tankless electric water heater, there’s no room for debate—it’s a practical and efficient choice for any home.
