How Hydronic Boilers Work
A hydronic boiler heats water and circulates it through a closed loop of pipes to radiators, baseboard heaters, or radiant floor tubing throughout your home. Unlike forced-air furnaces that blow heated air through ductwork, hydronic systems transfer heat through water -- a far more efficient medium. Water holds roughly 3,500 times more heat energy per unit volume than air, which is why hydronic heating delivers such even, consistent warmth.
The process begins at the boiler, where a gas burner or electric element heats water to a set temperature (typically 140-180 degrees Fahrenheit for radiators, or 80-120 degrees for radiant floor systems). Circulation pumps then push the heated water through supply lines to each heating zone. As the hot water passes through radiators, baseboards, or floor tubing, it releases heat into the room. The cooled water returns to the boiler through return lines to be reheated and recirculated.
Modern boiler systems use zone controllers to independently manage the temperature in different areas of your home. This means your living room can be kept at 72 degrees while bedrooms are set to 68 degrees, and unoccupied rooms can be turned down even further. Zone control maximizes comfort while minimizing energy waste -- you only heat the spaces you are using.
Types of Boilers We Install and Service
Gas Boilers
Gas-fired boilers are the most common type in the Big Horn Basin, using natural gas or propane as fuel. Modern gas boilers achieve efficiency ratings of 90-98%, with condensing models extracting maximum heat from combustion gases. Gas boilers heat water quickly and operate at lower cost per BTU than electric models.
Electric Boilers
Electric boilers use immersion heating elements to heat water. While they are nearly 100% efficient at the point of use, electricity costs more per BTU than gas in Wyoming, making them best suited for homes without gas service or as supplemental heating for specific zones.
Condensing Boilers
Condensing boilers represent the highest efficiency available in hydronic heating. They extract so much heat from combustion gases that the exhaust actually condenses, recovering latent heat that non-condensing boilers waste. Condensing boilers achieve AFUE ratings of 95-98%, making them the most economical choice for long-term operation. Navien's NCB and NHB series are condensing boilers.
Navien Boiler Expertise
Wrangler Plumbing has extensive experience installing and servicing Navien boilers, our preferred brand for hydronic heating in the Big Horn Basin. Navien's product line offers solutions for every application, from small homes to large custom residences with multiple heating zones and radiant floor systems.
Navien NCB Combi Boilers
The NCB series combines space heating and domestic hot water production in a single wall-mounted unit. This eliminates the need for a separate water heater, saving space and equipment costs. The NCB-240E provides 120,000 BTU for heating and on-demand hot water at up to 4.0 GPM -- ideal for smaller to mid-sized homes.
Navien NHB Series
For larger homes and dedicated heating applications, the NHB series delivers high-output hydronic heating with up to 199,000 BTU. These units pair perfectly with radiant floor systems and multi-zone heating configurations. The NHB series features a stainless steel heat exchanger for long-term durability.
Taco Zone Controllers
We pair Navien boilers with Taco zone controllers and circulation pumps for precise temperature management throughout your home. Taco's zone valve controllers allow independent temperature control for each heating zone, and their high-efficiency ECM circulation pumps move hot water through the system while using minimal electricity.
Advantages of Boiler Heat for Wyoming Homes
Comfort Benefits
- Even, consistent warmth without cold spots
- Silent operation -- no blower noise
- No drafts or air movement
- Does not dry out indoor air
- No dust or allergen circulation
- Zone control for room-by-room comfort
Practical Benefits
- No ductwork required
- Pairs with radiant floor heating
- Long lifespan (15-30 years)
- High efficiency (95-98% AFUE)
- Compact wall-mounted units save space
- Combi models provide hot water too
For Wyoming's Big Horn Basin climate, boiler heat offers a particular advantage: it maintains even temperatures throughout the home without the temperature swings common with forced-air systems. When outdoor temperatures drop to -20 or -30 degrees, a well-designed hydronic system keeps every room comfortable without the constant on-off cycling of a furnace.
Boiler systems also pair perfectly with radiant floor heating, delivering warmth from the floor up for the most comfortable heating experience available. Many of our clients choose a combination of radiant floors in main living areas and baseboard radiators in bedrooms and utility spaces.
Boiler Maintenance & Common Problems
Annual boiler maintenance is essential for safe, efficient operation and long equipment life. During a maintenance visit, our technicians perform a comprehensive inspection and service.
Annual Service Includes:
- Combustion analysis and burner adjustment
- Heat exchanger inspection and cleaning
- System pressure check and adjustment
- Expansion tank inspection and recharging
- Circulation pump operation check
- Zone valve testing
- Safety control verification
- Flue and venting inspection
Common Boiler Problems We Repair:
- Low system pressure or frequent pressure loss
- Circulation pump failure
- Zone valve malfunction
- Expansion tank waterlogging
- Ignition failure
- Scale buildup in heat exchanger
- Air lock in heating loops
- Thermostat and control issues
When to Replace Your Boiler
While boilers are built to last, there comes a point when replacement is more economical than continued repairs. Consider replacement when your boiler is over 20 years old, requires frequent repairs, has visible corrosion or leaks, or operates at efficiency below 80%. A new high-efficiency condensing boiler can reduce your heating costs by 20-30% compared to an older atmospheric boiler, paying for itself over time through energy savings.
We provide honest assessments of your existing boiler's condition and give you a clear comparison of repair costs versus replacement costs so you can make an informed decision.

Boiler Service FAQs
Boilers provide more even, consistent heat than forced-air furnaces. Hydronic heat eliminates drafts, cold spots, and the noise of a blower fan. Boilers also don't circulate dust, allergens, or dry air through your home. For Wyoming's cold climate, many homeowners prefer the comfortable, radiant warmth that a boiler system provides.
A well-maintained boiler can last 15-30 years depending on the type and quality. Cast iron boilers often last 25-30 years, while modern condensing boilers like Navien typically last 15-20 years. Annual maintenance is essential to achieving the full lifespan of any boiler system.
We specialize in Navien boilers, which offer excellent efficiency and reliability for Wyoming homes. Navien's NCB series combines heating and domestic hot water in a single unit, and their NHB series provides high-output heating for larger homes and radiant floor systems. We also service all other major boiler brands.
Boiler installation costs in Cody typically range from $5,000-$12,000 depending on the system type, size, and complexity. A Navien combi boiler for a smaller home may be on the lower end, while a full hydronic system with zone controls and radiant floor heating will be higher. We provide detailed written estimates.
Yes. Combination (combi) boilers like the Navien NCB series provide both space heating and domestic hot water from a single unit. This eliminates the need for a separate water heater, saves space, and reduces equipment costs. Combi boilers are an excellent choice for smaller to mid-sized homes.
