Radiant Heat Install Pt 2/5 | Control Panel | MAD County Build

This is part two of our radiant heat system installation. Today, we are diving into the process of setting up the control board, exploring the differences of fittings and connections, and making thoughtful decisions about thermostat types for optimal efficiency.

Now, let's dive into the details of our radiant heat system installation. Unboxing the control board marks the initiation of our endeavor. The control board, the brain of our system, is carefully mounted. We take extra care to ensure a secure and stable installation, considering its critical role in managing our multi-zone heating system. The control board is our central command, managing heating elements across different zones and responding to the signals from our carefully placed thermostats.


Transitioning to fittings and connections, our choice of using brass fittings and PEX pipes is a result of a careful planning process. These materials are selected not only for their durability but also for their efficiency in managing a seamless connection between the manifolds and pumps. Each connection is secured, considering the specific requirements of our system.

Adding another layer of stability, we introduce support brackets. These brackets not only enhance the structural integrity of our setup but also serve as a testament to the meticulous nature of our installation process. The goal is not just functionality but a visually clean and organized arrangement that reflects the professionalism of MR Post Frame.


As we progress, the focus shifts to the thermostats – the conduits through which we interact with our radiant heating system. The house circuits are wired with precision, with an emphasis on flexibility. We employ an 18/8 or 18/5 wiring setup, ensuring spare wires for potential future adjustments or replacements. The two-house circuits, representing zones three and four, are integrated into our system.

Now, let's talk about the heart of our heating system – the thermostats. A critical decision lies in choosing between in-slab sensors and air sensors. For the garage, where fluctuations in temperature are expected due to frequent door openings, an in-slab sensor seems important. This sensor is embedded in the concrete, providing a direct measure of the slab temperature and ensuring the system responds accurately to environmental changes. For other areas, an air sensor will do, functioning similar to traditional forced-air systems.


The versatility of the thermostats equipped with concrete sensors is highlighted. They offer a unique ability to be programmed for both air and concrete temperature. This versatility ensures that our heating system remains adaptive to changing conditions, creating a balance between efficient operation and optimal comfort. With all thermostats wired and our system ready for operation, we finish this phase of the installation process. The planning and attention to detail lay the foundation for a reliable and efficient radiant heat system.


Part three will take us into boiler installation in. Stay tuned for a comprehensive exploration of this important component that completes our radiant heat system.
