HVA Topeka delivers expert tankless water heater installation for families and businesses across Topeka and surrounding Kansas communities. Installing a tankless unit differs fundamentally from traditional tank replacement. Your existing gas line may be undersized by one or two pipe sizes, your home’s venting infrastructure may require complete redesign, electrical circuits need dedicated capacity, and water line expansion tanks become necessary in some installations. Most homeowners underestimate installation complexity and attempt DIY setups that fail to meet local codes, void manufacturer warranties, or create safety hazards. Our experienced technicians handle every technical requirement so your tankless system delivers reliable performance for its entire 20-year lifespan.
Your home’s gas supply line is likely sized at half-inch diameter, adequate for your previous tank water heater’s modest BTU requirements. A tankless unit demands 60,000 to 199,000 BTU depending on capacity, requiring gas line upsizing from half-inch to three-quarter inch or even one-inch diameter. This upsizing isn’t optional or cosmetic. Undersized gas lines create pressure drop that starves your tankless burners of adequate fuel, reducing heating capacity by 30-50%, triggering ignition problems, and violating manufacturer specifications. Professional gas line sizing using manufacturer calculation tables, pressure testing, and fitting assessment determines your exact requirements. Improper sizing causes your new tankless unit to fail within months.
Traditional tank water heaters vent through existing chimneys or simple wall vents. Tankless units produce lower-temperature exhaust unsuitable for standard chimneys, requiring dedicated direct venting or power venting systems. Concentric venting, where intake air and exhaust gas flow through a single pipe within a pipe assembly, provides the cleanest installation with minimal wall penetrations. This approach requires precision drilling through rim joists or walls, proper flashing installation, and outdoor termination hood positioning to prevent exhaust recirculation. Poor venting design causes carbon monoxide concerns, system shutdowns, and weathering damage that costs thousands to repair.
DIY tankless installation voids manufacturer warranty, potentially costing you $3,000-$5,000 if the unit fails within the first 2-3 years. Improper gas line sizing reduces capacity and triggers safety shutdowns. Incorrect venting creates carbon monoxide hazards and equipment failure. Inadequate electrical circuits cause burnouts and fire risk. Professional installation ensures compliance with all manufacturer requirements and local codes, protecting your 20-year equipment investment.
Unlike traditional tank water heaters occupying entire closets or utility room corners, tankless units mount on walls taking approximately one-quarter the physical space. This frees utility room space for storage, other mechanical equipment, or simply opens up your basement. The compact size also enables installation in attics, crawlspaces, outdoor walls, or tight garages impossible with tank models.
Tankless systems heat water only on demand, eliminating the 24-hour standby losses of tank models keeping 40-50 gallons constantly hot. This on-demand approach delivers 24-35% energy savings compared to traditional tanks, reducing water heating costs by $150-$400 annually depending on household usage. For larger families with simultaneous shower and laundry usage, the unlimited hot water supply means no more cold showers or scheduling conflicts.
