When the tubing circuits are crossed over the center of the joist cavity, have the system designer use nail plates to protect the radiant circuits from being punctured.
Climate Controls The following climate controls will minimize expansion and contraction during and after installation of the floor. This will monitor the room and keep the relative humidity at an even level, which will keep the equilibrium moisture content of the floor stable.
Heat Transfer Point Control: The system designer also should install a set point control that will monitor the wood floor temperature. The set point control should either reduce the system water temperature or temporarily cycle the system off to prevent overheating the flooring if equipment malfunctions. Exterior Thermostat: An exterior thermostat is recommended to protect the perimeter of the system from condensation absorption during the spring and fall when rapid temperature changes may occur.
Once the subfloor, tubing and climate controls have been installed, the heating system should run for at least 72 hours to bring the house to the desired relative humidity.
Temporary, unvented sources of heat - such as propane-fired "salamanders" - can add excessive amounts of water vapor. Avoid them if possible, but if they must be used, leave windows open to vent the humidity. A water heating system that can be either a standard boiler, water heater, a geothermal heat pump or even solar panels. The ability of the radiant heating system to either adequately heat the facility, or to simply warm the floor, without damaging the wood, must be taken into account when specifying a radiant heating system within any facility.
These are some of the most important variables to keep in mind when specifying or installing a wood floor over any radiant heating system:. The types of wood flooring best suited for under-floor radiant heat systems should be accounted for to ensure long-term performance.
Species Both in solid and engineered flooring options, certain species are known for their inherent dimensional stability such as mesquite, black cherry, black walnut, and others. Less stable species such as hickory, beech, and maple are less suitable for use over radiant heat.
Cut Wood is a hygroscopic and an anisotropic material, meaning it takes-on and throws-off moisture, and it shrinks and swells dependent on these changes in moisture differently in each direction. Wood shrinks and swells the most circumferentially around the growth rings tangentially , about half as much across the rings radially , and only minuscule amounts along the grain longitudinally.
The way in which it is cut from the tree for solid flooring is classified as plainsawn, quartersawn, riftsawn, livesawn, or end-grain. Quartersawn and riftsawn wood flooring are more dimensionally stable in width than plainsawn or end-grain wood flooring.
Width Wood changes dimension proportional to the width of the plank. Narrow boards expand and contract less than wider-width boards of the same species and cut.
Flooring Type Engineered wood flooring is, in general, more dimensionally stable than solid wood flooring. However, not all engineered wood flooring is recommended or appropriate for use over radiant heating systems. Engineered flooring with a less-stable wear layer species such as hickory, beech, and maple are not normally best suited over radiant heat unless otherwise suggested by the flooring manufacturer.
The cut and thickness of the wear layer lamina peeled, sliced, or sawn may also affect how the floor performs over radiant heat. Radiant Heating and Solid Hardwood Floors Radiant heat is usually not recommended for application with solid woods since being a natural material, exposure to high levels of moisture and extensive fluctuations in temperature result in contractions and expansions. Selection of wood The choice of wood type is quite important, and this becomes apparent once you understand the impacts of the available options.
Boards are cut from logs in two ways, these are; Quarter-sawn: The grain runs vertically Plain-sawn: The grain runs horizontally Plain-sawn woods, upon exposure to temperature variations, expand from side to side, and this will more likely than not lead to cupping and gaps.
Engineered Hardwoods For the installation of hardwood flooring over radiant heat, engineered woods make the better choice. Benefits of Radiant Heating with Wood Floors In-floor radiant heating systems are quite reliable and durable, plus they provide evenly distributed and set temperatures, which consequently assists in the preservation of hardwood floors and offer the possibility of lasting for up to 35 years.

Or call us at or Relating to the internal heat of the Earth. The water of hot springs and geysers is heated by geothermal sources. There are many advantages to geothermal energy. Geothermal energy is renewable energy because once water or steam is used, it can be pumped back into the ground.
It is also clean energy. Geothermal power plants, unlike plants that burn fossil fuels, do not produce greenhouse gases that can be harmful to the atmosphere. A geyser is a vent in the Earth's surface that periodically ejects a column of hot water and steam. A lava fountain is an example of the amount of heat stored in the Earth. Geysers, lava mountains and hot springs are all natural examples of geothermal energy. The three main uses of geothermal energy are: 1 Direct Use and District Heating Systems which use hot water from springs or reservoirs near the surface.
Geothermal Energy Disadvantages. Potential emissions — Greenhouse gas below Earth's surface can potentially migrate to the surface and into the atmosphere. Surface Instability — Construction of geothermal power plants can affect the stability of land.
Geothermal energy isn't entirely renewable—it will run out when the Earth does. In about 5 billion years. These nations generate the most geothermal power, based on their percentage of total power produced including fossil fuels and other renewable sources. Advantages of Geothermal Energy.
