Water Heater Installation & Replacement

Water Heater Installation in Portland

Water Treatment Background Behind Every Installation in Portland, ME

Most plumbers swap out a water heater and move on. We start by understanding your water. FONTUS provides water heater installation and replacement for homeowners and businesses in Portland, ME and surrounding areas, bringing a water-treatment perspective to work most companies treat as a straightforward swap. Sediment load, mineral content, and water source all affect how long a water heater lasts and how well it performs, so knowing what’s in your water before sizing and setting up a new unit can make a real difference.

We handle installation, client education, and ongoing system care, so you’re not left on your own once the work is done.

Why Portland Homeowners Choose FONTUS

Our founder, Thomas Marcisso, is a licensed Merchant Marine engineer who spent years managing potable water systems on oil platforms and commercial vessels, including serving as Chief Engineer on the F/V Wizard from Deadliest Catch. That background means installation decisions are grounded in real engineering, not just a manufacturer’s recommendation.

We also know Portland’s water sources. The city’s municipal supply draws from Sebago Lake and is naturally soft, while many properties in the surrounding area draw from private wells with higher mineral content. Those differences affect which unit fits a property best and how it’s configured. We assess your actual water source before making any recommendations, and we walk you through every decision so you understand what you’re getting and why.

Water Heater Types We Install

We install electric, gas (direct vent, atmospheric, and power vent configurations), heat-pump, and tankless water heaters. Each type suits different homes, fuel sources, and usage patterns, and no single option is right for everyone.

Tank vs. Tankless

Tank-style water heaters typically last 8 to 12 years. Tankless units can last 20 years or more, with actual lifespan shaped by usage, water quality, and how consistently the system is maintained. Tankless models heat water on demand rather than keeping a stored supply hot, which can reduce energy use for smaller households but may struggle to keep pace during peak demand in larger homes running multiple fixtures at once.

Sizing for Your Household

Correct sizing depends on peak hot water demand, not a one-size rule. A household running two showers simultaneously needs a unit sized for that load. Undersizing leads to cold water mid-shower; oversizing means paying to heat water you don’t use. We size each installation to match your actual usage patterns.

Signs Your Water Heater Needs Replacement

Rust-colored water, leaks around the tank, unusual rumbling or popping noises, and inconsistent heating are all signals worth taking seriously, especially once a tank unit passes the 10- to 12-year mark. These problems don’t typically resolve on their own.

Water source matters here too. Properties on private wells in the region often have harder, mineral-heavier water that accelerates sediment buildup inside a tank. That sediment layer insulates water from the heating element, forces the unit to work harder, and can shorten its service life. If your home draws from a well and your water heater is aging, it’s worth having both the unit and your water evaluated together.

What a FONTUS Water Heater Installation Looks Like

We don’t show up with a unit already picked out. Our process starts with your water and your usage. We test for iron, manganese, hardness, TDS, pH, alkalinity, salinity, and copper, and we assess your household’s hot water demand before recommending a unit or configuration. If water quality issues would affect the new heater’s performance, we flag treatment options alongside the installation itself.

Installation in Maine must comply with the state plumbing code, which adopts the Uniform Plumbing Code with Maine-specific amendments. Most replacement and new installation work requires a permit and inspection. We handle the work to code and walk you through what was done and how to keep the system running well after we leave.

Schedule Your Free Consultation in Portland, ME

Whether your water heater is aging, actively failing, or you’re building or renovating, we can help you find the right path forward. Our free consultation includes an immediate-response water test at no upfront cost, giving you a clear picture of your water quality and a plan to address anything that needs attention.

Call FONTUS at (207) 865-8165 to schedule your consultation and water test. There’s no cost to get started, and no obligation to move forward until you’re ready.

Maintenance & Long-Term Care After Installation

A new water heater is a long-term investment, and how it’s maintained affects how long it lasts. Annual flushing to clear sediment and periodic professional inspection are standard steps, particularly for properties where mineral content is a factor.

We offer proactive maintenance plans that include scheduled inspections, adjustments, and prompt repairs to help extend the life of your water heater and protect connected plumbing and appliances. If something needs attention between scheduled visits, you can reach us without starting the process over from scratch. We stay in contact after the work is done because the goal isn’t just a successful installation; it’s a system that can perform reliably for years.
