Oconomowoc — the crown jewel of Lake Country — has attracted Milwaukee-area families as a resort destination since the Victorian era. The lakefront estates along Lac La Belle, Fowler Lake, and Oconomowoc Lake Road include some of the oldest and most architecturally significant homes in Waukesha County — properties with 100-year heating histories that have seen coal, oil, and gas boilers come and go over the generations.
Victorian-era Milwaukee summer estate conversions in Oconomowoc often retain original cast iron boiler infrastructure — radiators, supply mains, and return piping — even when the boiler itself has been replaced. Newer boilers piped to old distribution systems can create compatibility challenges that require experienced diagnosis. Interior subdivision development along Summit Avenue and eastern Oconomowoc from the 1990s and 2000s reflects modern construction with forced-air as the primary system, but custom homes throughout the city increasingly specify radiant floor heating.
Burkhardt Heating, Cooling, Plumbing & Electric serves Oconomowoc from our Brookfield location, reaching the city in about 30 minutes via I-94. We work on all types of boiler systems found in Oconomowoc — from original cast iron steam configurations in lakefront estates to modern condensing boilers in newer radiant floor applications. Pressure system failures, circulator pump wear, zone valve malfunctions, and steam trap problems are all within our daily service scope.

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: Weil-McLain, Burnham, Buderus, Lochinvar, Navien, Slant/Fin, Crown, Peerless, and Utica.
My Oconomowoc lakefront home has original radiators from the 1920s. Can they work with a new boiler?
In most cases, yes. Cast iron radiators are very durable and compatible with modern hot water boilers. The key is proper sizing and piping configuration — a new boiler must be matched to the existing distribution system's flow and temperature requirements. Burkhardt handles historic system boiler replacements regularly in Lake Country.
My Oconomowoc home has radiant floor heat and the boiler is showing an error code. What should I do?
Note the error code and call Burkhardt at 414-206-3049. Do not simply reset the boiler without understanding the cause — repeated resets without diagnosis can damage boiler components. Our technicians have diagnostic tools for all major modulating boiler brands and will identify the root cause.
How do I prevent my Oconomowoc boiler from failing during a Wisconsin cold snap?
Annual maintenance is the single best prevention. A pre-season tune-up checks combustion, safety controls, pressure components, and expansion tank condition — addressing wear before it becomes a failure. Burkhardt recommends scheduling boiler maintenance in September or October, before the heating season demand peaks.
