Germantown is a Washington County village with German immigrant heritage, 1970s–1980s ranch neighborhoods along Appleton Avenue, and rural-to-suburban transition zones. For homeowners throughout Washington County who rely on a boiler for home heating — or who want to add one — Burkhardt Heating, Cooling, Plumbing & Electric brings over 60 years of experience installing and replacing boiler systems across southeastern Wisconsin. older Germantown ranches with gravity or early forced-air systems benefit most from modern high-efficiency condensing boiler upgrades.
High-Efficiency Condensing Boilers
Today's condensing boilers are a major step forward from the cast-iron systems that heated ranch homes, raised ranches, and split-levels for decades. Standard boilers waste a significant share of fuel energy through exhaust gases. A condensing boiler captures that waste heat by cooling exhaust until it condenses, extracting an additional round of energy before venting. The result: AFUE ratings of 90–98%, versus 60–80% for older equipment. For Germantown homeowners heating through long Wisconsin winters, that efficiency gap has a measurable impact on annual energy bills.
Radiant Floor Heating
High-efficiency condensing boilers pair naturally with radiant floor heating systems, which warm floors and objects directly rather than circulating hot air. The result is even temperature distribution, no cold spots, and a comfort level that forced-air systems can't replicate. Washington County homeowners adding finished basements, tile floors, or open-concept spaces are increasingly including radiant floors — and a properly sized condensing boiler is the most efficient way to power them.
Steam-to-Hot-Water Conversions
Many of the older ranch homes, raised ranches, and split-levels throughout Germantown were originally heated by steam boiler systems. Steam systems are more complex to maintain, prone to comfort inconsistencies, and typically less efficient than modern hot-water systems. Converting to a hot-water condensing boiler with updated distribution improves comfort, simplifies maintenance, and cuts fuel consumption. Burkhardt crews have completed hundreds of these conversions across the Milwaukee metro.
Right-sizing matters: an oversized boiler short-cycles and wears out faster; an undersized one can't keep up on January nights. Our technicians perform a full heat-loss calculation before specifying any new system.

Radiant Heating Systems
Many boiler systems in Southeastern Wisconsin power radiant floor heating — one of the most comfortable and energy-efficient heating methods available. Our technicians are experienced with hydronic radiant systems, including in-floor tubing, baseboard radiators, and cast iron radiator systems found in older Milwaukee-area homes. Whether you need radiant system repairs, zone valve replacement, or a new radiant floor installation, we handle the complete system.
We work on all boiler brands including Weil-McLain, Burnham, Buderus, Lochinvar, Navien, Slant/Fin, Crown, Peerless, and Utica. From cast iron steam boilers in older Milwaukee homes to modern high-efficiency condensing units, we've seen and repaired them all.
How do I know if my Germantown home's boiler should be replaced rather than repaired?
Boilers typically last 15 to 25 years with proper maintenance. Replacement usually makes more economic sense when: the system is over 20 years old, repair costs exceed half the cost of a new unit, efficiency has declined noticeably, or the system requires frequent service calls. Our technicians will give you an honest assessment of whether repair or replacement is the better investment.
Can a new boiler handle both heating and domestic hot water in my Germantown home?
Yes. Many modern condensing boilers can be configured as combination (combi) units that handle both space heating and domestic hot water, eliminating the need for a separate water heater. This is particularly attractive in Germantown homes with limited mechanical room space. We'll evaluate your home's hot water demand and heating load to determine whether a combi unit or separate systems are the better fit.
