Cast iron boilers can last 30 to 40 years in well-maintained systems, but modern high-efficiency condensing boilers operate at AFUE ratings of 90–98%, compared to 70–80% for older atmospheric units. When a boiler is aging, experiencing repeated failures, or simply no longer meeting the home's heating load, replacement with a modern condensing unit can significantly reduce fuel costs while improving comfort. HVAC Pros. handles boiler replacement in Campbellsport, WI including full removal of the existing unit, installation of the new boiler and associated controls, flue modification (condensing boilers use PVC venting rather than a traditional chimney flue), and system commissioning including pressure testing, air bleeding, and control programming. We match the new boiler's output to your home's heat loss not just the old unit's nameplate BTU to ensure it performs optimally in your specific system.
Combination (combi) boilers represent a particularly compelling option for homes in Campbellsport, WI with space constraints, as they provide both heating and domestic hot water from a single compact unit, eliminating the need for a separate water heater. However, combi boilers are sized differently than dedicated heating boilers domestic hot water demand is the sizing driver and improper sizing leads to performance complaints about hot water delivery. HVAC Pros.'s installation approach accounts for both the heating load and the peak domestic hot water demand before any equipment is specified. We also evaluate whether the existing distribution system piping, radiators, baseboard, or radiant tubing is compatible with the new boiler's operating temperature range, since modern condensing boilers perform best with lower system water temperatures than older atmospheric units were designed for.
