Lochinvar Boiler Configurations We Install

We install and service Lochinvar boiler systems for residential space heating and domestic hot water. Lochinvar’s lineup covers several configurations, so we can match the right unit to your home’s layout and heating load rather than defaulting to a one-size-fits-all approach.

High-efficiency condensing boilers: These units capture heat from exhaust gases that standard boilers vent away, which can help lower operating costs and support a higher AFUE efficiency rating.
Combi boilers: A combi boiler handles both space heating and on-demand domestic hot water in a single compact unit, freeing up significant space compared to running a separate boiler and water heater.
Wall-mounted boilers: Ideal for homes with limited mechanical room space, wall-mounted models keep the footprint small without sacrificing output.
Floor-standing boilers: Suited to homes with higher heating demands or where wall mounting isn’t practical.
Modulating boilers: These units automatically adjust their output to match your home’s actual heating demand rather than cycling fully on and off, which can improve both efficiency and comfort.

Our technicians also work with all makes and models of residential boilers, including gas, electric, and high-efficiency condensing units, so if you have a system outside the Lochinvar lineup, we can still help.

Free Estimates, Financing & Same-Day Service

We offer free estimates on boiler installation and replacement so you know exactly what to expect before any work begins.

Our team answers calls 24/7 and schedules same-day appointments, including weekends, across Arvada and the surrounding Greater Denver Area.

Signs Your Boiler Needs Replacement

Not every boiler problem calls for a full replacement, but some warning signs point clearly in that direction. Knowing what to look for helps you act before a minor issue becomes a heating emergency.

Frequent or escalating repair costs: One repair can be reasonable. A pattern of repairs in a short span often signals a boiler nearing the end of its service life.
Rising energy bills without explanation: A boiler that’s losing efficiency works harder to deliver the same heat, and that shows up in your utility costs.
Uneven heating: Rooms that never reach a comfortable temperature or have significant variation across floors can indicate a failing or undersized unit.
Unusual noises, leaks, or visible corrosion: Banging, kettling, or physical deterioration are common signs of boiler failure that shouldn’t be ignored.
Carbon monoxide detection: This is a safety emergency. Shut the system down immediately and call for an evaluation before restarting.

When you’re not sure whether repair or boiler replacement in Arvada makes more sense, we’ll give you an honest evaluation. Our goal is the right long-term answer for your home, not the most expensive one.

What Professional Boiler Installation Involves

A boiler installation isn’t just an equipment swap. Several technical and regulatory steps help the system run safely and at peak efficiency.

Sizing the Right System

Proper sizing comes first. We use a Manual J load calculation, a standardized method that accounts for your home’s square footage, insulation, window area, and local climate, to verify the replacement unit matches your actual heating demand. An oversized or undersized boiler creates comfort problems and efficiency losses regardless of how well it’s installed.

Permits, Inspections & Code Compliance

The City of Arvada requires a building permit for residential boiler replacements and new installations, and that permit must be approved before work begins. Installations exceeding 200,000 BTUs also require a separate permit and inspection from the State of Colorado. Our licensed, insured team handles the permitting process as part of every installation, so the work is inspected, documented, and code-compliant, including gas connections, venting, and all associated work.

Keeping Your Boiler Running After Installation

A new boiler is an investment, and regular maintenance protects it. Routine service helps the system run efficiently, can extend its service life, and is often required by manufacturers to keep equipment warranties valid. Skipping annual tune-ups can void coverage you paid for.

Our Service Club membership makes ongoing care straightforward. Members get priority scheduling, exclusive discounts on repairs, and annual tune-ups that keep the system dialed in year after year. It’s a simple way to stay ahead of problems rather than react to them.
