Hardwood floors can dry out and suffer damage due to thermal expansion. The sensor is used to provide the following options: Tekmar thermostats also include the option to install a floor temperature sensor. Their thermostats use Pulse Width Modulation and Indoor Temperature Feedback technology to periodically pulse the floor with the right water temperature so that the floor maintains a steady constant temperature, thereby maintaining optimal comfort. It can be quite unpleasant riding this temperature rollercoaster! The result is the floor tends to shoot past the air heating temperature when heating and then does not turn back on until the floor temperature is cold. These thermostats turn on the radiant floor when the air is below the temperature setting, and shut off when it’s above the temperature setting. Regular forced air heating thermostats are not well suited to operating radiant floor heating systems. The water valves should be identified to indicate which plumbing fixture is being controlled from that specific valve. They also have individual shut-off valves allowing to turn-off a single fixture or a specific conduit without affecting other areas of the building. These centralized systems are made of adapters, end caps, and fittings that normally are designed or specified in customized manifolds depending on the intended application. Manifolds are used to distribute water in radiant, snow-melting, and hydronic applications. Plumbing manifolds are that central place where water is distributed into smaller pipes and sent through the radiant heat system. Manifolds are like the “heart” of a radiant floor system. Since the Onix does not expand or contract with temperature changes, it is the quietest system around.Īs long as the tubing chosen is installed properly and per the manufacture’s recommendations, the radiant heat system will perform beyond expectations. It is the only product that can be installed under a frame floor with no additional accessories required (no heat transfer plates, no special clips). It’s the most diversified product in the market today. This product is typically used in slab or thin-slab applications, but can also be installed under a frame floor with the use of heat transfer plates or clips.įor under joist or where complex bends are needed like stairs in a snow and ice melt system we us Watts Radiant’s Onix tubing. We typically use two different varities of tubing in our floor loops. Zone controllers: Low voltage controllers for managing multiple calls for heat from different zones in the home.Zone valve: Control hot water circulation through multiple heating zones.Service Valves: All for servicing of the system without a complete shut down.Mixing Valves: To temper outgoing domestic hot water from or to help control radiant floor heat temperature.Dirt separator: The dirt separator removes these dirt particles, collecting them in a large collection chamber from which they can be flushed even while the system is in operation.Air elimination components: Automatic air purging devices referred to as air scoops, air purgers, or air separators vary in internal design, but all are intended to capture air in hot water piping, sending it either to an expansion tank or to an air bleeder/air vent.Pressure relief valves: Safety device prevents boiler explosions by releasing temperature and pressure if other safety controls fail.Expansion Tank: Boiler expansion tanks are metal tanks of varying sizes that are installed to absorb the initial pressure increase that occurs when the boiler water heats up.Circulator Pumps: Force hot water through the plumbing system.The boiler and floor loops will have many small very important components installed with them. Modern boilers also have built-in logic that will operate your radiant floor on “cruise control”, slowly changing the water temperature based of information it receives from an outdoor temperature sensor. The heat required by most residential radiant floor heating systems can vary greatly, boilers are the best choice for matching the heat output to the load. Modern boilers on the other hand, are specifically engineered to operate at these lower water temperatures, increasing your energy savings and comfort. What equipment is required for radiant floor heating?īoiler selection is critical, and it is important to know that conventional boilers work in a much hotter range, losing efficiency, and requiring protective measures to prevent damage to themselves or the floor.
