We're a family-owned and operated company based right here in Longmont. That means when your hot water heater quits on a freezing Front Range winter morning, you're not calling some faraway call center. You're calling neighbors who understand Longmont homes, our hard water, and the way Colorado winters push heating systems to their limit. Whether you need a quick repair, a brand-new install, or help deciding between tank and tankless, our licensed and insured plumbers are ready to help.
Our Water Heater Services in Longmont
Water heaters are one of those things you don't think about until they stop working. That's why EP Plumbing, Heating & Air offers full-service care, everything from diagnostics and repairs to full replacements and preventative maintenance. Below is a closer look at what we do.
Water Heater Installation and Replacement
Sometimes a repair just doesn't make sense anymore. If your unit is over 10–12 years old, rusting at the base, or you're calling for service every few months, replacement is usually the smarter long-term choice.
We handle water heater installation in Longmont CO for every type of system:
- Gas water heaters – fast recovery rates and lower operating costs
- Electric water heaters – simple, reliable, and great for homes without gas lines
- Hybrid heat pump water heaters – excellent energy efficiency for the right home
- Tankless units – endless hot water in a compact footprint
Proper sizing matters more than most people realize. Too small and you run out of hot water. Too big and you're wasting energy every single day. We look at your household size, fixtures, and habits before recommending a unit.
Every water heater replacement we perform includes correct venting, an expansion tank when needed, a working pressure relief valve (T&P valve), and a full safety inspection. We install to Colorado code and pull permits where they apply, so your system is safe and legal from day one.
Common signs it's time to replace:
- Frequent, costly repairs
- Rusty or discolored water
- Visible leaks or corrosion at the tank
- Rising energy bills
- The unit simply can't keep up with demand
Water Heater Repair
Many problems don't require a full replacement, just an experienced hand and the right part. Our water heater repair in Longmont covers issues big and small, including:
- No hot water – often a failed heating element, pilot light, or thermostat
- Water won't stay hot – frequently caused by sediment buildup or a bad thermostat
- Leaking tank or fittings
- Rust-colored water – can point to a failing anode rod or corroded tank
- Rumbling or popping noises – a classic sign of hard water sediment
- Pilot light or gas burner troubles
- Pressure relief valve or expansion tank problems
Our technicians run a full diagnostic to find the true cause, not just the symptom, then give you honest options. If a $150 part will get you a few more good years, we'll tell you. If the unit is failing, we'll be straight with you about that too.
Tankless Water Heater Services
A tankless water heater heats water on demand instead of storing it in a tank. Water flows through the unit, gets heated instantly, and keeps flowing as long as you need it. No more running out mid-shower.
Why homeowners love them:
- Endless hot water for back-to-back showers and big laundry days
- Energy savings since there's no tank losing heat all day
- Space savings, these units mount on a wall
- Long lifespan when maintained properly
That said, tankless isn't right for every home. Larger families with high simultaneous demand sometimes need multiple units or a properly sized model. We walk you through it honestly so you know what to expect.
We also repair tankless systems. Because our hard water causes mineral scale to build up inside the heat exchanger, tankless units need periodic descaling. If your tankless unit is throwing error codes or losing performance, we can diagnose and fix it.
Water Heater Maintenance and Flushing
A little maintenance goes a long way. Longmont's hard water leaves mineral sediment at the bottom of your tank, and over time that layer forces your unit to work harder, waste energy, and wear out faster.
Our maintenance visits include:
- A full water heater flush to remove sediment buildup
- Anode rod inspection (the part that protects your tank from rust)
- Pressure relief valve testing
- Thermostat and heating element checks
- Expansion tank inspection
- A general safety and efficiency review
Annual maintenance can:
- Reduce surprise repair costs
- Extend the life of your water heater
- Improve energy efficiency
- Keep your hot water supply steady and reliable
Think of it like an oil change for your water heater, cheap insurance against an expensive breakdown.
What Affects Water Heater Costs
One of the most common questions we hear is about the 50-gallon water heater replacement cost in Longmont. The honest answer? It depends. Pricing varies based on:
- Repair versus full replacement
- Tank size and fuel type (gas vs. electric)
- Tankless versus traditional units
- Installation complexity and venting requirements
- Any needed plumbing modifications or code upgrades
- Permit requirements where they apply
- Emergency versus scheduled service
The best way to get an accurate number is an on-site evaluation. We provide free estimates so you know exactly what to expect, no surprises.
