Why Installing Water Heaters Right Matters
Installing a water heater might seem straightforward, but it’s more complex than just hooking up a tank and turning it on.

Choosing the Right Water Heater for Your Needs
Before installation, you need to pick the right water heater type. There are several options, each with pros and cons depending on your space, budget, and hot water demand.
Types of Water Heaters

Tankless Water Heaters
These heat water on demand without storing it. They are compact and energy-efficient.
Pros: Endless hot water, space-saving, energy-efficient
Cons: Higher initial cost, may require electrical upgrades
Heat Pump Water Heaters
These use electricity to move heat from the air to heat water, making them very efficient.
Pros: Energy-efficient, environmentally friendly
Cons: Higher upfront cost, needs space with good airflow
Solar Water Heaters
These use solar panels to heat water, reducing energy bills significantly.
Pros: Renewable energy, low operating cost
Cons: High installation cost, dependent on sunlight
Factors to Consider
Household Size: Larger families need bigger tanks or multiple units.
Energy Source: Check what’s available and cost-effective in your area.
Space: Some units require more room or special venting.
Budget: Balance upfront cost with long-term savings.
Once you’ve chosen the right type, you’re ready to plan the installation.
Preparing for Installing Water Heaters
Preparation is key to a smooth installation. Here’s what you should do before the installer arrives or before you start if you’re tackling it yourself.
Check Local Codes and Permits
Waukesha has specific plumbing and electrical codes. Make sure you or your installer are familiar with these. Sometimes, a permit is required for water heater installation to ensure safety and compliance.
Gather Necessary Tools and Materials
If you’re doing the installation yourself, you’ll need:
Pipe wrenches and pliers
Pipe cutter and tubing
Teflon tape and pipe sealant
Soldering kit (for copper pipes)
Electrical tools (if electric heater)
Venting materials (for gas heaters)
Pressure relief valve and expansion tank
Turn Off Utilities
Before starting, turn off the water supply and power or gas to the existing water heater. Drain the old tank completely to avoid spills.
Plan the Location
The water heater should be installed in a place that’s accessible for maintenance but protected from freezing temperatures. Proper ventilation is critical for gas models.

Step-by-Step Guide to Installing Water Heaters
Here’s a straightforward overview of the installation process. Remember, if you’re not confident, hiring a professional is the safest choice.
1. Remove the Old Water Heater
Turn off power/gas and water supply.
Drain the tank completely using a hose.
Disconnect water lines and vent pipes carefully.
Remove the old unit.
2. Position the New Water Heater
Place the new heater on a stable, level surface.
Ensure it’s close to existing plumbing and venting points.
3. Connect Water Lines
Attach cold water inlet and hot water outlet pipes.
Use Teflon tape or pipe sealant to prevent leaks.
Install a new pressure relief valve if not pre-installed.
4. Connect Gas or Electrical Supply
For gas heaters, connect the gas line and check for leaks with a soapy water test.
For electric heaters, connect wiring according to the manufacturer’s instructions.
5. Install Venting (Gas Heaters)
Attach vent pipes securely to direct exhaust gases outside.
Ensure proper slope and clearance as per code.
6. Fill the Tank and Check for Leaks
Open the water supply and fill the tank.
Open a hot water faucet to let air escape.
Inspect all connections for leaks.
7. Power On and Test
Turn on the gas or electricity.
Set the thermostat to the recommended temperature (usually 120°F).
Monitor the heater for proper operation.
When to Call a Professional for Water Heater Installation
While some handy homeowners might feel comfortable installing a water heater, there are many reasons to hire a licensed plumber or technician:

Maintaining Your Water Heater for Long-Term Performance
Installation is just the beginning. To keep your water heater running smoothly, regular maintenance is essential.
Simple Maintenance Tips
Flush the Tank Annually: Sediment buildup reduces efficiency and damages the tank.

Check the Anode Rod: Replace it every few years to prevent tank corrosion.
Inspect for Leaks: Look for water pooling or rust around the unit.
Adjust Temperature Settings: Keep it at 120°F to save energy and prevent scalding.
When to Replace Your Water Heater
Most water heaters last 8-12 years. Signs it’s time for a new one include:
Frequent repairs
Rusty or discolored water
Inconsistent water temperature
Strange noises from the tank
Upgrading to a newer, more efficient model can save money and improve comfort.
