Before installing a hot water heater, there are a few important things to understand that can affect your comfort, energy usage, and long-term costs. First, know what type of system fits your home best — standard tank or tankless. Tank heaters are generally more affordable upfront, while tankless models offer better energy efficiency and continuous hot water, but may require additional setup.

Next, check local building codes and permit requirements. In many areas, water heater installations must follow strict safety standards, especially for gas models. Working with a licensed professional ensures everything is up to code and safely installed.

It’s also important to consider the size of the unit. A heater that’s too small won’t meet your household’s needs, while one that’s too large could waste energy. Water pressure, ventilation, and location (such as garage, closet, or attic) all play roles in proper setup.

Finally, ask about warranties and maintenance. Some models require routine flushing or servicing to extend their life and maintain performance.

Gas vs. Electric: Which Type Should You Choose?

Choosing between a gas and electric water heater depends on your home’s setup, energy costs, and hot water needs. Each type has its own strengths, and understanding the differences can help you make the right call.

Gas water heaters typically heat water faster and recover more quickly after heavy use, making them ideal for larger households. They’re generally more cost-effective to operate if your area has low natural gas rates. However, they require proper ventilation and may involve higher upfront installation costs — especially if you’re switching from electric.

Electric water heaters are easier to install and don’t require venting, which can be a plus for tight or indoor spaces. They’re also very efficient at converting energy into heat, but may have slower recovery times compared to gas. In areas with high electricity rates, long-term operating costs may be higher.

Other factors include environmental impact — electric heaters can be powered by renewable energy, while gas produces direct emissions. If you’re considering solar or future energy upgrades, electric may offer more flexibility.

If your home already supports one type, sticking with it can reduce installation complexity. Still, it’s worth comparing efficiency ratings, available rebates, and long-term operating costs to make the most informed choice for your household.

Common Code Requirements and Safety Considerations

Installing a water heater isn’t just about connecting pipes — it also requires meeting local building codes and following safety standards to protect your home and family. Whether you’re using gas or electric, there are several common requirements to be aware of.

Proper venting is essential for gas water heaters. Exhaust gases must be safely directed outside to prevent carbon monoxide buildup. Vent pipes need to be the correct size, slope, and material, and any changes to the system must comply with current codes.

Expansion tanks are often required if your home has a closed plumbing system. These tanks relieve pressure caused by water heating and help prevent damage to pipes or the water heater itself.

Seismic strapping may be necessary in certain regions to secure the unit and prevent tipping during an earthquake. Drain pans and discharge piping are typically required when a heater is installed in an attic or other interior space, helping contain and redirect leaks safely.

Electrical and gas connections must be done correctly, using shut-off valves, proper grounding, and pressure testing when necessary. Water heaters must also be installed at specific clearances from walls, appliances, and combustible materials.

Working with a licensed professional helps ensure every detail is handled properly — not just for efficiency, but for long-term safety and compliance.
