Boiler & Hydronic Heating Services

If your home or building relies on radiant heat, you know how important it is for your boiler system to operate safely and efficiently. At Minnesota Plumbing, we specialize in boiler service, hydronic heating repairs, and system upgrades that keep your space warm and comfortable during even the harshest Minnesota winters. Whether you’re dealing with inconsistent heat, rising energy bills, or a complete system failure, our team is here to help with expert solutions and honest advice.

Hydronic heating systems are known for their quiet operation, even heat distribution, and long-lasting performance. But like any mechanical system, they require regular maintenance and prompt repairs to perform at their best. Our licensed professionals are trained to work on all types of boilers, radiant floor systems, and zone controls—so whether your setup is decades old or brand new, we have the experience to service it properly.

Expert Boiler Repairs

Boiler problems can range from minor annoyances to major disruptions, especially during the peak of heating season. If you notice unusual noises, fluctuating temperatures, or water leaks around your boiler, don’t wait. Our team can quickly diagnose the issue and provide a targeted repair that restores performance without unnecessary upsells or delays.

Common boiler problems include low pressure, faulty thermostats, pilot light issues, expansion tank failure, and mineral buildup. We carry many common parts on our trucks, allowing us to resolve most boiler issues on the first visit. If a replacement is needed, we’ll explain your options clearly and help you make the best long-term decision for your home and budget.

For hot water radiators, baseboard heat, or in-floor systems, we also inspect and repair associated components like air vents, zone valves, and circulation pumps to ensure the entire hydronic system is working efficiently from start to finish.

Radiant Floor Heating Service

In-floor heating is one of the most comfortable and efficient ways to warm your home, but it requires specialized knowledge to install and maintain. If you’re experiencing cold spots, uneven heating, or slow response times with your radiant system, Minnesota Plumbing can help.

We service both electric and hydronic radiant floors, including PEX tubing systems that circulate warm water beneath the surface. From system flushing and air purging to pump replacements and sensor calibrations, we’ll restore your system’s performance and keep every room at the perfect temperature.

If you’re considering radiant heat for a remodel or new construction project, we can also help design and install a custom system that meets your space and energy needs. We work closely with contractors and homeowners to ensure every detail—from layout to control—is built for long-term comfort and efficiency.

Boiler Replacement & System Upgrades

If your boiler is more than 15 years old, requires frequent repairs, or struggles to heat your space effectively, it might be time for a replacement. Today’s high-efficiency boilers offer major improvements in performance, energy savings, and reliability.

At Minnesota Plumbing, we install top-rated boilers from trusted brands and ensure they’re properly sized and integrated with your existing distribution system. Whether you’re replacing a cast iron unit or switching from forced air to radiant heat, we’ll guide you through the upgrade with clear communication and transparent pricing.

We also offer system upgrades like programmable thermostats, smart zoning controls, and energy-efficient circulators to help you get more from your heating system year-round.

Preventive Maintenance for Boilers

Routine maintenance is essential to keeping your boiler and hydronic system running efficiently and safely. Our maintenance services include pressure checks, expansion tank inspection, flushing of mineral buildup, thermostat calibration, and pump testing. Annual tune-ups help catch minor issues before they turn into costly breakdowns—and they often extend the lifespan of your system significantly.

If you rely on your boiler to heat both your home and your domestic hot water, regular inspections are even more important. We’ll make sure all safety controls are functioning properly and provide recommendations to keep everything operating smoothly through the winter and beyond.

Boilers for Homes, Shops & Small Businesses

Boilers aren’t just for homes—we also service radiant systems in shops, outbuildings, and small commercial spaces. If you use a boiler to heat your garage, studio, or business property, we can help ensure it runs reliably all season long. We offer repair, replacement, and maintenance services for light commercial applications, and we’re happy to work around your business hours whenever possible.

We understand that downtime can be costly, which is why we focus on fast response times, accurate diagnostics, and clean, professional workmanship on every job.
