Sussex is a newer community by Milwaukee-area standards — its rapid growth during the 1990s and 2000s means most of its housing stock was built during the era of high-efficiency forced-air systems. Traditional steam or hot water radiator boilers, common in pre-1960s urban and inner-ring suburban homes, are not a regular feature in Sussex. Most homes along the N. Pine Lake Road subdivision corridor and the Pewaukee Road growth areas heat with natural gas furnaces.
That said, Sussex is not without boiler systems. Radiant floor heating — a modern hydronic technology powered by a condensing boiler — has been specified in a growing number of Sussex's upscale custom homes and higher-end production builds. Homeowners who invest in radiant floor systems appreciate the comfort they deliver, but those systems require a boiler to function, and as they age into the 15-to-20-year range, service calls become more frequent.
Burkhardt Heating, Cooling, Plumbing & Electric serves Sussex from our Brookfield location, reaching the village in about 20 minutes via I-41. We diagnose and repair condensing boilers in radiant floor applications — reading fault codes, replacing zone valves and circulators, servicing expansion tanks, and advising on whether an aging boiler warrants repair or replacement. Our technicians carry diagnostic tools for all major boiler brands.
Burkhardt is available 24/7 for emergency boiler service in Sussex. When your radiant floor system stops working in the middle of a Wisconsin winter, we respond — day or night. GreenSky financing is available for boiler replacement.

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.
My Sussex home has radiant floor heat but the boiler keeps shutting off. What should I check?
Repeated shutdowns are usually caused by a safety control detecting an out-of-range condition — low water pressure, overtemperature, ignition failure, or a sensor reading incorrectly. Do not simply reset and ignore repeated lockouts. Call Burkhardt at 414-206-3049 for an accurate diagnosis before the problem worsens.
How long do condensing boilers in radiant floor systems last in Sussex homes?
Modern condensing boilers are typically rated for 15 to 20 years with proper maintenance. Annual tune-ups — combustion analysis, heat exchanger inspection, pressure check — extend service life significantly. Burkhardt recommends scheduling boiler maintenance each fall before heating season begins.
Is radiant floor heat worth the additional cost in a Sussex home?
For many Sussex homeowners, yes — radiant systems deliver exceptional comfort with no drafts or dust circulation, and they can be very efficient when the boiler is properly sized and maintained. If you are considering adding radiant to a renovation project, Burkhardt can advise on system design and costs.
