Radiant Heating Mechanical Systems
Pre-Assembled Boiler Boards & Complete Hydronic Mechanical Packages
Complete Hydronic Heating Systems Start with Proper Mechanical Design
A high-performance radiant floor heating system requires more than just quality radiant floor panels and tubing. While the floor distributes the heat throughout the building, the hydronic mechanical system is responsible for generating, controlling, and delivering that heat efficiently.
At Warm Brothers Inc. (WBI), we specialize in designing engineered radiant floor heating systems, including panel layouts, tubing layouts, manifold locations, zoning strategies, and complete distribution designs. However, the mechanical room is the other half of every successful installation.
A properly engineered hydronic mechanical system ensures your radiant floor operates efficiently, provides consistent comfort, protects expensive equipment, and delivers reliable performance for decades.
For customers who need a professionally engineered solution without designing an entire mechanical room from scratch, WBI proudly partners with InFloor Mechanical Solutions, a leader in custom-built hydronic mechanical packages and pre-piped boiler boards.
The Two Critical Components of Every Radiant Heating System
A complete hydronic radiant floor heating system consists of two equally important systems working together.
1. Radiant Floor Distribution System
Designed by Warm Brothers Inc.
- Radiant floor panel layout
- PEX tubing layout
- Loop balancing
- Manifold placement
- Zone planning
- Floor covering compatibility
- Heat distribution optimization
This system determines where the heat goes.
2. Hydronic Mechanical System
The mechanical room determines how the heat is produced, controlled, and delivered.
- High-efficiency boiler or heat source
- Heat pump integration
- Primary/secondary piping
- Hydraulic separator or low-loss header
- Circulator pumps
- Expansion tanks (one for potable if the system includes domestic, one for space heating)
- Air separator
- Pressure reducing valve
- Backflow preventer
- Mixing valves
- Zone valves
- Isolation valves
- Purge and fill stations
- Temperature sensors
- System controls
- Thermostat integration
- Safety relief valves
- Electrical control panel
Each component is selected and engineered to work together as one complete hydronic heating system.
Why Mechanical Design is so Important
Many people think installing radiant heat simply involves connecting a boiler to tubing beneath the floor. In reality, every hydronic heating system requires careful engineering.
Proper mechanical design considers:
- Boiler sizing
- Pump sizing
- Flow rates
- Head loss calculations
- Supply water temperatures
- Multiple heating zones
- Primary and secondary piping
- Hydraulic separation
- Expansion volume
- Air elimination
- Equipment protection
- Domestic hot water integration
- Future serviceability
- Long-term operating efficiency
A Properly Engineered Radiant Heating Mechanical Room Delivers:
- Higher system efficiency
- Better comfort
- Stable floor temperatures
- Lower operating costs
- Longer equipment life
- Cleaner installations
- Easier servicing
- Fewer installation mistakes
Simply put, the mechanical room is the engine that powers your radiant floor heating system.
Custom Pre-Piped Boiler Boards
A Professional Mechanical Room, Built Before It Arrives
Not every builder, homeowner, or plumbing contractor specializes in hydronic heating. That’s where InFloor Mechanical Solutions comes in.
Rather than sourcing dozens of components and building an entire mechanical room in the field, InFloor designs and assembles a custom mechanical board specifically for your project. Each hydronic boiler board is professionally engineered, custom built to order, and shipped ready for installation.
Depending on your project, your custom package may include:
- Pumps
- Valves
- Headers
- Expansion tank
- Air separator
- Controls
- Hydraulic separator
- Piping
- Mounting board
- Wiring (where applicable)
- Magnetic Dirt Separator
- Fill valve and back flow preventor
- Ball valve pump flanges
- Exhaust and intake air
The installer simply mounts the mechanical board, installs the boiler or heat source, connects the field piping, completes the electrical connections, and commissions the system.
The result is a cleaner installation, faster installation time, fewer field errors, and confidence that the mechanical room has been professionally engineered.

Frequently Asked Questions
What is a hydronic mechanical system?
A hydronic mechanical system is the equipment that heats and circulates water through a radiant floor heating system. It typically includes the boiler or heat source, circulator pumps, expansion tank, hydraulic separator, controls, valves, manifolds, appliance venting, and safety devices. While the radiant floor distributes the heat, the mechanical system is responsible for producing, controlling, and delivering it efficiently.
What is a boiler board or mechanical board?
A boiler board (also called a mechanical board or hydronic mechanical package) is a professionally assembled panel that contains many of the components required for a radiant heating system. Rather than building the mechanical room piece by piece on-site, the system arrives pre-piped and organized, making installation faster, cleaner, and more reliable.
Why is mechanical design important for radiant floor heating?
Even the best radiant floor layout cannot perform properly without a well-designed mechanical system. Proper mechanical design ensures the correct water temperatures, flow rates, pump sizing, and controls are used so the system operates efficiently and provides consistent comfort throughout the home.
Can my plumber install a radiant heating system?
Many plumbers can install radiant heating systems, but hydronic heating requires specialized knowledge beyond standard plumbing. A professionally engineered mechanical package helps simplify installation while reducing the possibility of piping, control, or component selection errors.
What components are included in a hydronic mechanical package?
Every project is different, but a custom mechanical package may include:
- Boiler connections
- Circulator pumps
- Hydraulic separator
- Expansion tank
- Air separator
- Mixing valves
- Zone controls
- Isolation valves
- Fill and purge valves
- Pressure relief valve
- Backflow preventer
- Temperature sensors
- Electrical controls
- Piping and mounting board
- Magnetic dirt separator
- Manifolds
- Ball valve pump flanges
- Exhaust and intake air
Each package is engineered specifically for the heating requirements of the project.
Can I install the mechanical board myself?
Many owner-builders and experienced contractors install pre-piped mechanical boards successfully. Because much of the engineering and assembly has already been completed, installation is significantly simplified. Final plumbing, electrical connections, boiler installation, startup, and commissioning should always comply with local building codes and manufacturer recommendations.
Do I still need a radiant floor design if I purchase a mechanical package?
Yes. The radiant floor system and the mechanical system are designed together but serve different purposes. WBI designs the floor layout, tubing layout, loop lengths, manifold locations, and heat distribution. The mechanical package is engineered to supply and control that system.
Can a mechanical package work with a boiler or a heat pump?
Yes. Mechanical packages can often be designed around a variety of heat sources, including high-efficiency gas boilers, gas combination units, electric boilers, air-to-water heat pumps, geothermal heat pumps, and other compatible hydronic heat sources. The mechanical design is customized to match the specific equipment and heating requirements of each project.
What are the benefits of a pre-piped boiler board?
Compared to building a mechanical room entirely on-site, a custom mechanical board offers several advantages:
- Faster installation
- Cleaner appearance
- Professionally engineered layout
- Reduced installation errors
- Easier servicing
- Better organization
- Consistent component placement
- Reduced labor time
- A project specific piping and wiring diagram
- Technical support
Does every radiant heating project need a custom mechanical package?
Not necessarily. Some experienced hydronic contractors prefer to build their own mechanical rooms.
