Choosing the Right Boiler Replacement in Denver

Boiler Replacement in Denver: Gas, Electric & Combi Options for Colorado Homes

Colorado winters can be harsh—especially along the Front Range—so when your boiler starts struggling to keep up, it’s time to explore your boiler replacement options. Whether your home uses a gas, electric, or combi boiler, choosing the right system for Colorado’s climate, altitude, and efficiency standards is essential for dependable comfort all winter long.

At Mac-Vik Plumbing, Heating, Electrical & Air Conditioning, we help homeowners across Denver and the surrounding areas choose, install, and maintain the ideal boiler for their homes.

This guide breaks down boiler types, trusted brands, available rebates, and how to know when replacement makes more sense than repair.

Why Boiler Selection Matters in Colorado

Colorado’s unique climate, dry air, and high elevation create special considerations for heating systems. Boilers installed above 5,000 feet need to be sized and calibrated correctly.

Boiler Replacement Options for Denver Homes

At Mac-Vik, we install and service gas, electric, and combi boilers from trusted manufacturers. Here’s what you should know about each type.

1. Gas Boilers — The Reliable Colorado Standard

Best for: Most Denver-area homes

Gas boilers are a popular choice in Colorado. They provide strong heat, work efficiently, and last a long time. This makes them great for larger or multi-story homes.

2. Electric Boilers — Compact and Low-Maintenance

Best for: Smaller homes or all-electric properties

Electric boilers provide quiet, clean, and efficient heating with minimal maintenance. Although operating costs may be higher than with gas, they’re an excellent option when access to gas is limited.

3. Combi Boilers — Heat + Hot Water in One

Best for: Homes upgrading both heating and hot water systems

Combi (combination) boilers deliver both home heat and domestic hot water from a single, energy-efficient unit. These systems are ideal for smaller homes or families looking to streamline energy use.
