Sure, thermal mass provided by a slab is great, and concrete is a better conductor of heat than wood. Some purist installers think that the only way to make radiant work is to pour a slab over the tubing, whether that be a concrete slab on grade or a lightweight Gyp-Crete slab over plywood subfloor. There is some debate that different methods of installing in-floor radiant systems provide varying levels of responsiveness, comfort and efficiency. For a house, the temperature of the air is taken into account by giving a minimum and a maximum to the concrete slab, in this way if an outside door would remain open when it is very cold, the floor would stop rising when it would reach the maximum temperature of the slab.By Rocky DiTommasso, Northeastern Supply.Thus, the air flow created during the opening of the door will not trigger the start of the system, the temperature of the slab has not necessarily decreased. The temperature of a garage is usually set according to that of the slab.This information can be obtained from your electrician or from the boiler manufacturer’s brochure.Ī floor sensor takes into consideration the temperature of the concrete slab in order to adjust the room temperature. What is the power of the circuit breaker required to power the boiler ? What is the use of an outdoor temperature sensor ?īy being informed of the variations of the outside temperature thanks to the probe, the boiler can adjust the temperature of the water / glycol of its tank and thus allow to offer more heat to the slab in cold weather and avoids the problems of overheating when the weather becomes milder An outdoor temperature sensor is also supplied with the boiler The Mini Ultra boiler is a smart model that only heats the water in its tank when a thermostat requires it, which saves energy. A circuit breaker installed on the top of the boiler makes it possible to extinguish it in the spring and to reignite it in the fall. If we tell it to heat the water to 100 degrees F, it will heat the tank water to 100F continuously. The mini BTH is similar to a small 2 gallon hot water tank. Which boiler to choose, Mini BTH or Mini Ultra ? Here is the required diameter of the boiler inlet / outlet piping depending on the area to be heated:ģ000 ft2 to 5000 ft2: 1 1/4 in diameter Info tips The diameter of the inlet and outlet pipes are therefore generally 3/4 inch, which does not allow sufficient flow for floors with an area greater than 1500 ft2. Instant water heaters are designed to heat domestic water.Heating with a hot water tank means heating 40 to 60 gallons continuously, which increases heating costs.These appliances do not have CSA approval for heating.Some might be tempted to use a standard hot water tank or a domestic water instant water heater to reduce the cost of purchase but avoid making this mistake.Possibility of using a probe to adapt to variations in the temperature of Canadian winters (the temperature of the water / glycol varies with the outside temperature).The boiler modulates the heating power of the water / glycol according to demand.Exceeding this length, the temperature difference between the out and the return may be too great, which will make some parts of the floor cooler and therefore less comfortable. The maximum length of a loop is 300 feet. We often hear about loops and zones, what is the difference between the two ?Ī loop is a length of pipe that goes back and forth through the floorĪn area is a section of the floor (usually a room) consisting of one or more loops controlled by a thermostat. If the pipes are installed between the joists we calculate the total area multiplied by 2.If the pipes are installed at a distance of 9 inches, we calculate the total area multiplied by 1.5. If the pipes are installed at a distance of 12 inches we calculate the total area multiplied by 1.2 (example: 500 ft2 x 1.2 = 600 feet of pipes).How to calculate the amount of piping required ? Reduces corrosion that can occur in the system and increases component life.We use our own line of PEX piping, which makes our prices very competitive.
