The Comfort Of Radiant Without The Mechanical Room

Enjoy the simplicity of electric indoor floor heating and turn cold concrete floors into a welcoming comfort. SlabHeat, by Watts Radiant, is ideal for basements, garages, sunrooms, offices, warehouses, and countless other interior slab projects.

Operating a SlabHeat system couldn't be easier. Simply connect a SunStat Control or Relay directly to the SlabHeat cable with either 120 or 240 VAC line power. Each SunStat automatically turns the system on and off when needed.

What Is Electric Slab Heating?
SlabHeat is an electric heating cable used solely for indoor applications. It is perfect for new construction or remodeling projects.

  • Can be installed in a slab cap, a new slab or over an existing slab. 
  • Cable can be spaced depending on your warming needs. 
  • Single point connection.
  • Available in 120VAC and 240VAC

Reducing Boiler Noise

What causes boiler noise?

Boiler noise is usually the result of limescale deposition within the heat exchanger of a boiler. This condition is worsened if magnetite is also present in the system, as this combines with the limescale to form a much harder deposit. Other sediment-forming debris such as sand and brick dust entering the system during installation can also become part of the hardened deposit. Local water conditions also play an important part, particularly the scale-forming solids dissolved in the supply water.

Boiler noise is directly related to the rapid condensation or implosion of steam in water. Localized boiling develops on the surface of the deposit, and small steam bubbles are created that make a rattling noise as they leave the surface and travel around the system.

When installed into existing systems, new boilers can become excessively fouled soon afterwards by oxide sludge present in the system water. Replacing a boiler can disturb soft sludge and loosen sediment in other parts of the system, causing it to be transported by the system water and re-deposited in the new heat exchanger.

The same phenomenon can occur as a result of circulator replacement if flow rates change. The risk of sediment and sludge deposition in new boilers can be avoided by cleaning the system as part of the installation process.

What should be done?

Fernox DS40 System Cleaner selectively dissolves oxide sludge without attacking metals commonly found in central heating systems. However this acid-based cleaner should only be used in new installations.

Older systems that have been untreated for periods of time may have existing leaks that are temporarily plugged with corrosion debris. Installations with a history of radiator corrosion failures should not be acid cleansed, as other radiators are likely to have deep corrosion pits or complete perforations.

Older installations can be substantially improved, however, by dispersing the sludge with Fernox Cleaner F3 or Powerflushing Cleaner F5 , followed by power flushing with plain water.

After removing all soft sludge from older installations separate boiler de-scaling may be helpful. In order to do this, the radiators should be isolated after which the system can be descaled over a period - up to 24 hours.

This should be followed by rinsing with plain water and neutralizing to passivate the surfaces within the system. Fernox DS40 System Cleaner and Neutraliser can be used in this process.

After cleaning, the entire system should be re-treated using Fernox Protector F1 to eliminate the causes of boiler noise.

Premium Reflective Bubble Insulation That Can Be Used Virtually Anywhere!

Space Age insulation, by Insulation Solutions, is rolled, easy-to-use insulation designed to create a more comfortable living/working space and help cut down on energy costs. Adding a radiant barrier to existing insulation can boost the overall R-value of the building by preventing radiant heat gain. Conversely, in the winter, radiant barriers assist with keeping the space warm by reducing heat loss. Unlike mass insulation, Space Age contains no itchy fibers and cuts easily with a knife or scissors. Available in double bubble and single bubble configurations, Space Age is manufactured in convenient sizes so waste is minimized and installation is simplified.

Common applications include attics, walls, HVAC ducts, water heaters, pole barns, metal buildings, marine/RV, radiant heating and crawl spaces. Depending on your given application(s), Space Age is available with single-sided or double-sided reflectivity.
