Tankless Water Heaters
Tankless Water Heater Services in Topeka and Lawrence, KS

Need a new system or service for an existing unit? We handle tankless water heater installation, repair, replacement, and maintenance. A properly sized tankless water heater can provide hot water on demand while reducing the space needed for a traditional storage tank. Our team helps homeowners evaluate hot water needs, fuel options, and budget to determine the right solution. We also provide complete plumbing services for homes throughout the region.
Tankless Water Heater Installation
Tankless water heater installation should be handled by a licensed plumber. The system must be sized correctly for the home's hot water demand and connected to the appropriate plumbing, electrical, gas, and venting systems.
Dunco helps homeowners choose equipment based on household size, water flow requirements, fuel type, and budget. A gas tankless water heater and an electric tankless water heater each have different installation requirements, making proper sizing and professional installation important for long-term performance.
Tankless Water Heater Replacement
Tankless water heater replacement may be the right choice when an existing unit develops recurring repair issues, struggles to keep up with demand, or no longer operates efficiently. Some homeowners replace an older tankless unit. Others transition from a traditional storage tank to a tankless system.
When comparing options, Dunco can help evaluate both tankless systems and other water heater services to determine the best fit for your home.
Tankless Water Heater Repair
Tankless water heater repair is needed when the system produces no hot water, delivers inconsistent temperatures, displays an error code, develops a leak, or shuts down unexpectedly.
Low water flow, ignition issues, mineral buildup, and heat exchanger problems can all affect performance. If your tankless water heater is not heating properly, professional diagnosis can identify the cause and recommend the appropriate repair. We also provide plumbing repairs when related plumbing issues contribute to the problem.
Tankless Water Heater Maintenance
Routine tankless water heater maintenance can help protect system performance and extend equipment life.
Maintenance includes flushing tankless water heater systems to address mineral buildup, inspecting components, checking water flow, and verifying safe operation. Regular service can reduce unexpected breakdowns and identify developing problems before they become larger repairs.
Benefits of a Tankless Water Heater
Many homeowners choose a tankless water heater because it offers convenience, efficiency, and space savings.
- Hot water on demand without storing heated water in a large tank.
- Compact equipment that requires less space than many traditional systems.
- An energy-efficient water heater may help reduce energy consumption depending on household size, usage habits, fuel type, and equipment selection.
- No large storage tank taking up floor space.
Like any water heating system, performance depends on selecting equipment that matches the home's hot water demand.
