Boiler Installation & Replacement
Boiler Installation and Replacement in Kansas City and Lenexa, KS
When a boiler system reaches the end of its service life, or when repair costs make replacement the better long-term investment, Lutz handles the complete installation process: assessment, system selection, removal of the old unit, installation, startup, and system testing. We work with both steam and hot water boiler systems and carry experience with the full range of residential heating configurations common in older Johnson County neighborhoods.
Modern high-efficiency condensing boilers represent a significant efficiency improvement over the systems they replace in most mid-century Kansas City homes. If your home has a boiler that is 30 or more years old, a new condensing unit will reduce your heating costs meaningfully. Call (913) 631-2667 or schedule a consultation online.
When Boiler Replacement Makes Sense
Boilers last longer than most other home heating equipment. A well-maintained cast iron boiler can deliver 30 to 40 years of service. The decision to replace is typically driven by one or more of the following:
- The boiler is leaking from cracked sections in the cast iron heat exchanger. This is structural damage that repair cannot address cost-effectively on an older unit.
- Repair costs on a single service call are approaching $1,500 or more on a system that is already 25-plus years old.
- The boiler operates at 65-75% AFUE efficiency and energy bills reflect that gap. Modern condensing boilers operate at 90-95% AFUE or higher.
- The heating system is being upgraded as part of a whole-home renovation, and the existing boiler configuration does not match the new scope.
- Parts for the specific boiler model have become difficult to source, making continued repair impractical.
If repair is still the right answer, we will say so and fix it. See our boiler repair page for how we approach that evaluation.
High-Efficiency Condensing Boilers: What They Offer
Standard non-condensing boilers vent hot exhaust gases through a metal flue, losing a significant portion of the heat generated in the combustion process. Condensing boilers extract a second stage of heat from those exhaust gases, cooling them to the point where water vapor condenses out. That recovered heat is what drives the efficiency rating to 90-95% AFUE or above.
The practical result is a significant reduction in natural gas consumption for the same heating output. For a Johnson County home spending $1,500 or more per year on gas heat, the utility savings from upgrading to a condensing boiler can reduce payback time on the system to seven to ten years, depending on current AFUE and heating load.
High-efficiency condensing boilers also vent through PVC pipe rather than metal flue, which simplifies installation in many older homes where the original chimney flue has deteriorated or been abandoned.
Steam to Hot Water Conversions
Some homeowners with older steam boiler systems choose to convert to a hot water (hydronic) system when the steam boiler requires replacement. This involves replacing the boiler, converting or replacing radiators for hot water compatibility, adding a circulator pump, and modifying the distribution piping. The conversion eliminates the operational complexity of a steam system and makes the heating system more compatible with modern high-efficiency boilers.
This is a more involved project than a straight boiler replacement and requires careful assessment of the existing radiators and piping. We evaluate every conversion project individually before recommending it.
Integration with Plumbing and Domestic Hot Water
Some homeowners choose to combine a new boiler installation with an indirect water heater, using the boiler to produce domestic hot water as well as space heating. This is an efficient approach for homes that are already investing in a high-efficiency boiler and want to consolidate their heating equipment. Our team has the plumbing background to handle the integration of heating and domestic hot water systems in a single project.
Frequently Asked Questions
How much does a new boiler installation cost in Kansas City?
A standard hot water boiler replacement in the Kansas City area typically ranges from $4,000 to $9,000 installed, depending on system size (BTU output), efficiency rating, brand, and installation complexity. High-efficiency condensing boilers and steam system replacements tend toward the higher end of that range. We provide a specific written quote after assessing your home and existing system.
How long does a boiler installation take?
A standard boiler replacement typically takes one to two days. Complex projects involving steam-to-hot-water conversion, significant piping modifications, or integration with a domestic hot water system may take longer. We will give you a realistic timeline during the assessment.
Is a high-efficiency condensing boiler worth the extra cost in Kansas City?
For most older Johnson County homes replacing a 65-75% AFUE system, yes. The utility savings from a 90-95% AFUE system are meaningful on the scale of a Kansas City heating season. The premium cost of a condensing unit over a standard non-condensing boiler typically pays back in six to ten years in heating bill reductions, and the system continues producing savings for the remainder of its 20-year service life.
Can I switch from a boiler to a forced-air furnace?
Yes, though it is a larger project than a boiler replacement. Converting to forced-air heating requires designing and installing a ductwork system throughout the home, which adds significant cost. Some homeowners prefer to stay with hydronic heat because radiator systems provide comfortable, even warmth and do not circulate dust. We can assess both options and give you a realistic cost and comfort comparison. See our furnace installation page for information on the forced-air path.
Does Lutz install boilers in older homes in Prairie Village, Fairway, and Westwood?
Yes. These neighborhoods are exactly where most of the residential boiler replacement work in Johnson County occurs. Our technicians are familiar with the range of older heating configurations in these homes, including the steam systems found in pre-1940 construction.
Is financing available for a new boiler?
Yes. Financing is available for qualifying homeowners. See our financing page for options, or ask during your installation consultation.
