Warmth That Rises From the Floor

Radiant floor heating design and installation for homes and commercial spaces in Minneapolis, St. Paul, and surrounding areas

When you walk barefoot across a tile floor in winter and feel warmth instead of cold, that is radiant heating. Minn Mechanical Contractors LLC designs and installs in-floor radiant heating systems for homes, garages, workshops, and commercial buildings in St. Paul. Instead of blowing hot air through vents, radiant systems warm the floor itself, which then radiates heat upward to create even, comfortable warmth throughout the room.

We install radiant floor heating during new construction and remodeling projects in St. Paul, placing tubing or heating cables under tile, hardwood, or concrete before the finished floor goes down. The system connects to a boiler or water heater and runs quietly without ductwork, fans, or moving air. You get consistent heat that does not dry out the air or create cold spots near windows and exterior walls.

Installation That Fits Your Floor Type

We start by designing the radiant loop layout based on your floor plan, room use, and heat loss calculations for Minnesota winters. In St. Paul, radiant systems are commonly installed in bathrooms, kitchens, basements, mudrooms, and garages where even heat and dry floors make a noticeable difference. Tubing is secured to the subfloor or embedded in a concrete slab, then tested for leaks before the finished floor is installed.

Once the system is running, you will notice your floors stay warm to the touch, rooms heat evenly from floor to ceiling, and your thermostat can be set lower because radiant heat feels warmer than forced air at the same temperature. Provides even, comfortable heat for Minnesota winters means you stay comfortable without the drafts or noise that come with traditional furnaces and ductwork.

Radiant heating works well with tile and stone, and can also be installed under engineered hardwood or laminate with proper insulation underneath. Systems are zoned by room or area so you control temperatures independently without heating the entire house. We also pair radiant floor heating with high-efficiency boilers and smart thermostats to reduce energy use and give you control from your phone.

What Homeowners Want to Know

Radiant heating is different from forced air systems, so it helps to understand how it works and what to consider during installation.

What rooms work best with radiant floor heating?
Radiant heating works best in rooms with tile or concrete floors such as bathrooms, kitchens, basements, and mudrooms. It is also popular in garages and workshops where keeping the floor warm and dry matters more than fast heat-up times.
How long does it take for radiant heat to warm a room?
Radiant systems take longer to heat up than forced air because they warm the floor mass first, usually one to two hours depending on floor type and insulation. Once warm, the floor holds heat longer and provides steady comfort without cycling on and off.
What kind of boiler do I need for radiant heating?
You need a boiler or water heater that can maintain consistent low-temperature water flow through the radiant loops. Many high-efficiency condensing boilers work well with radiant systems because they operate efficiently at lower water temperatures.
Can I install radiant heating under hardwood floors?
You can install radiant heating under engineered hardwood or laminate, but not under solid hardwood because it can warp from heat and moisture. Proper insulation under the tubing is required to direct heat upward and protect the flooring.
Why is radiant heating a good choice for Minnesota winters?
Radiant heating provides even warmth without blowing air, which helps during long Minnesota winters when forced air systems can dry out indoor air and create drafts. It also works well in spaces like garages and basements that are harder to heat with ductwork.
