Installing a Water Heater the Right Way
Adding a water heater where there wasn't one before — for a new build, an addition, a converted space, or a property that's never had a proper unit — is a different job from repairing or replacing an existing one. There's no old system to reference, which means every decision, from sizing to placement to venting, has to be made correctly from scratch. Get it right and you'll have reliable hot water for well over a decade with minimal issues. Get it wrong — an undersized unit, poor venting, incorrect gas or electrical connections — and you're looking at recurring problems or a redo down the line. We'll help you choose the right size and type for your specific situation, then handle the full installation to code.
What We Help You Decide
- Tank vs. tankless, based on your household's hot water needs, available space, and budget for upfront cost vs. long-term efficiency
- Correct sizing for your home's square footage, number of bathrooms, and typical simultaneous hot water demand (showers, dishwasher, laundry all running at once, for example)
- Gas vs. electric, based on what utility connections are already available at the property and which makes more sense for your situation
- Placement and venting requirements, especially important for gas units, which have specific code requirements for exhaust and combustion air
Our Process
Walk the space with you.
We assess where the unit will go, what connections already exist, and what will need to be added.
Talk through your options honestly.
Tank vs. tankless, sizing, and fuel type all have real trade-offs — we'll lay them out clearly rather than pushing the most expensive option.
Handle permitting.
Water heater installations typically require a permit and inspection, and we manage that process as part of the job.
Install to code.
All connections — water, gas or electric, and venting — are completed to current code requirements.
Test and walk you through the unit.
Once installed, we confirm proper operation and show you anything you need to know about your new system, including basic maintenance.
What Affects the Installation
The scope of a new installation depends on a few factors: whether existing gas, water, and electrical lines are already run to the location or need to be added, the type of unit you choose (tankless installations often have different venting and electrical requirements than tank units), the distance from the unit to where hot water is needed most (affecting wait time at the tap), and any code updates required if the space wasn't previously plumbed for a water heater at all.

Why This Isn't a DIY Job
A new water heater installation involves gas or electrical connections, water line connections, and — critically — code-compliant venting, all of which require a permit and inspection in most jurisdictions. Getting venting wrong on a gas unit isn't a minor issue; it's a genuine safety concern related to combustion byproducts. Beyond safety, an installation that doesn't pass inspection can create real headaches if you're trying to close out a permit for a larger renovation or addition — getting it right the first time matters.

Tank vs. Tankless: Which Makes Sense for a New Installation
For a brand-new installation, this decision is worth taking seriously since you're not constrained by an existing setup. Tank water heaters have a lower upfront cost and are simpler to install, but they take up more space and have a finite hot water supply at any given time. Tankless units cost more upfront and have more specific installation requirements (venting and often a dedicated gas line or electrical circuit), but they take up less space, last longer on average, and provide continuous hot water rather than a limited tank capacity. We'll talk through which fits your household's actual usage rather than defaulting to one or the other.
Frequently Asked Questions
It comes down to household size, number of bathrooms, and peak hot water demand — how many showers, appliances, or fixtures might realistically run at the same time. We'll calculate this with you rather than guessing; an undersized unit means running out of hot water, an oversized one wastes energy and money.
Choosing the Right Location for Your New Water Heater
Placement matters more than many homeowners expect. A unit installed far from where hot water is used most (kitchen, primary bathroom) means a longer wait for hot water at the tap and more water wasted while it heats up. For gas units, the location also needs to accommodate proper venting and combustion air requirements. We'll help you weigh convenience, code requirements, and available space when deciding where your new unit goes.
Getting the Most Out of a New Installation
A properly sized, correctly installed water heater should give you years of reliable service with minimal maintenance. Once installed, a simple annual flush and periodic anode rod check (for tank units) will help you get the full expected lifespan out of your new system.
