Phase Change Floor Tiles for Passive Solar InspectAPedia®  -     Q&A on use of phase-change floor tiles for passive solar slab design Sol-Ar-Tile, polymer-resin concrete tiles for floors & ceilings using Colloidal Materials' pouches Questions & answers about phase-change floor tiles for passive solar heating systems Solar Age Magazine Articles on Renewable Energy, Energy Savings, Construction Practices

Passive solar floor heating: This article discusses the use of phase-change floor tiles for passive solar floor design

Accompanying text are reprinted/adapted/excerpted with permission from Solar Age Magazine - editor Steven Bliss. Our page top photograph shows a horrible radiant floor slab insulation scheme installed by a Minnesota contractor - this radiant floor system never worked because the tubing was placed too deep in the concrete slab and the insulation system was incomplete.

Readers should see FLOOR, CONCRETE SLAB CHOICES and also see SLAB INSULATION, PASSIVE SOLAR and other articles at SOLAR ENERGY SYSTEMS. Contact us to suggest text changes and additions and, if you wish, to receive online listing and credit for that contribution.

Passive Solar Floor Tile Choices - Phase-Change Tiles

Floor Coverings for Passive Solar Thermal Mass Floors

The question-and-answer article below paraphrases, quotes-from, updates, and comments an original article, (see links just above) from Solar Age Magazine and written by Steven Bliss.

Question:

A few years ago I read about floor tiles with phase-change salts inside their hollow cores for use over thermal-mass slabs in passive solar heating designed homes. An upcoming project I'm involved in could benefit from such a project. Could you please supply me with information on suppliers or manufacturers of phase-change floor tiles for use over insulated slabs? -- Gary Higgins, North Windham ME

Answer:

We mentioned Sol-Ar-Tile™ in Solar Age articles in February 1982 (p.40), and May 1983 (p. 69).

The manufacturer, Ar-Lite Panelcraft Inc., (formerly Architectural Research Corp.), uses Colloidal Material's pouches in polymer resin concrete tiles for floors and ceilings.

Penwalt Corp. produces and packages phase-change materials that can be embedded in floors, ceilings, and walls.

• "Passive Solar Home Design", U.S. Department of Energy, describes using a home's windows, walls, and floors to collect and store solar energy for winter heating and also rejecting solar heat in warm weather.
• "Solar Water Heaters", U.S. Department of Energy article on solar domestic water heaters to generate domestic hot water in buildings, explains how solar water heaters work. Solar heat for swimming pools is also discussed.
• "Heat Exchangers for Solar Water Heating Systems", U.S. DOE describes the types of solar water heater heat exchange methods between the sun and the building's hot water supply
• "Heat-Transfer Fluids for Solar Water Heating Systems", U.S. DOE, describes the types of fluids selected to transfer heat between the solar collector and the hot water in storage tanks in a building. These include air, water, water with glycol antifreeze mixtures (needed when using solar hot water systems in freezing climates), hydrocarbon oils, and refrigerants or silicones for heat transfer.

• "Solar Air Heating" U.S. DOE also referred to as "Ventilation Preheating" in which solar systems use air for absorbing and transferring solar energy or heat to a building
• "Solar Liquid Heating" U.S. DOE, systems using liquid (typically water) in flat plate solar collectors to collect solar energy in the form of heat for transfer into a building for space heating or hot water heating. The term "solar liquid" is used for accuracy, rather than "solar water" because the water may contain an antifreeze or other chemicals.
