Ever wondered what it takes to switch to a tankless water heater? These systems are energy-efficient, provide endless hot water, and take up less space. But before you make the jump, you need to understand the plumbing and electrical setup required. At Better Water Heaters, we specialize in tankless water heater installation in Los Gatos and know exactly what it takes to get your system up and running.

Let’s walk you through the key plumbing and electrical requirements so you can make an informed decision.

Why Does the Installation Matter?

A tankless water heater isn’t a simple plug-and-play system. It requires a proper setup to function efficiently and safely.

● If the plumbing isn’t done right, you could face water pressure issues.

● If the electrical system isn’t up to code, your unit may not get enough power.

● Gas-powered units need proper ventilation to prevent carbon monoxide buildup.

By understanding these requirements, you’ll avoid costly mistakes and ensure your heater operates at peak efficiency.

Plumbing Essentials: What You Need to Know

A tankless water heater works differently from traditional models, meaning your plumbing setup needs a few tweaks.

1. Pipe Sizing Matters

Unlike conventional tanks, tankless units heat water on demand, requiring a higher flow rate. Your existing pipes might not be large enough to handle the increased demand.

● Water Supply Lines: Many homes need to upgrade to ¾-inch pipes for better flow.

● Gas Lines (For Gas Units): You may need to upsize to ensure proper fuel delivery.

2. Proper Drainage for Condensation

If you choose a high-efficiency gas unit, it produces condensation that must be drained. We install a proper drainage system to prevent water buildup and corrosion.

3. Shut-Off Valves and Isolation Kits

Shut-off valves allow for easy maintenance and emergency shut-offs. An isolation kit is also essential for flushing out mineral buildup, extending the life of your unit.

Electrical Setup: Are You Ready?

Even if you opt for a gas-powered tankless water heater, you’ll still need electricity to power the controls and ignition system. Here’s what to check:

1. Voltage and Amperage Requirements

● Electric models require a dedicated circuit and higher amperage (typically 120-240V).

● Gas models only need a standard 120V outlet for ignition and controls.

Before installation, we assess your home’s electrical panel to ensure it can handle the new load.

2. Dedicated Circuit for Safety

Your water heater should not share a circuit with other appliances. A dedicated circuit prevents overload and potential power failures.

3. Grounding and Surge Protection

Electrical fluctuations can damage your heater. We always recommend grounding the unit and adding a surge protector for extra protection.

Practical Tips for a Smooth Installation

Want to make sure your installation goes off without a hitch? Follow these steps:

✔ Check Your Home’s Water Pressure – Low pressure can impact performance.

✔ Confirm Gas Line Capacity – If you’re switching from electric to gas, your home must have the proper gas line size.

✔ Ensure Proper Venting – Gas units need outdoor venting to safely remove exhaust gases.

✔ Hire a Professional – DIY installs can lead to code violations, leaks, or safety hazards. Let Better Water Heaters handle it!

FAQs

1. Can I replace my traditional water heater with a tankless one without modifying my plumbing?

Not always. Many homes require pipe upgrades to meet the higher flow demand.

2. How much electricity does a tankless water heater use?

It depends on the model. Electric tankless heaters require a dedicated 240V circuit, while gas models need minimal electricity for ignition.

3. Do I need a permit for tankless water heater installation?

Yes. Local building codes require permits for both plumbing and electrical work. We handle all the paperwork for you.
