Cheap Solar Heat
Posted by radiant heat in In Floor Radiant Heat on July 29th, 2010
Last winter my boys and I made a very cheap solar heater with a large south facing window in our second story computer/ homeschool room. We just hung a black plastic sheet on the inside of the window with curtain rods. This left about 1.5″ for natural convection to take place. It draws the cooler air near the floor and the heat just flows out the top. This room would always get warm with the sun shining in, but with just this black sheet I was able to turn off my heater (forced air) and just leave the fan on to circulate this heat throughout the house. I also used a portable fan to move heat out of that room so we could stand working in there on our computers. On sunny days with below freezing temperatures outside , I could shut off our heater from 11:00 am to about 6:00 pm and stay perfectly warm and comfortable inside the house.
ZED Floor Plan, Passive Solar Thermal Buffer Zone
Posted by radiant heat in In Floor Radiant Heat on July 8th, 2010
Zero Energy Design® coined the term “Thermal Buffer Zone” in the materials about our first ZED home in 1979. It is the extremely efficient concept that two small temperature differentials result in lower undesirable heat transfer than one large exterior envelope temperature differential. Since 1979, “TBZ” has appeared in popular architecture literature many times, but most Architects(R) still do not understand how to use it cost effectively in a zero energy building. This narrated video shows a beautiful, open, efficient, abundant-daylight floor plan, and how our refined Double Shell Thermal Buffer Zone transfers solar gain from the sunny side of the home, to the cold side of a Zero Energy Design building with NO electricity. We also describe summer Energy Recovery Ventilation solar cooling, and how we hide all solar panels and satelite dishes from view on all sides.

VELUX solar hot water installed in solar test home
Posted by radiant heat in Roof Heating on May 16th, 2010
A three collector, 120 gallon Velux solar hot water system was installed in the solar test home. Water in the solar storage tank is heated to 160 degrees using an antifreeze solution which circulates between the collectors on the roof and a heat exchanger installed inside the storage tank located in the garage. Domestic hot water is delivered at 120 degrees throughout the home summer and winter. Annually, this system generates 16 megawatts of free hot water using only sunlight.

SOLAR ENERGY Want to live “off the grid?” Harness the sun’s heat and energy with solar panels to efficiently power your home, or just offset your home’s energy use to reduce costs. GEOTHERMAL ENERGY Geothermal energy is power extracted from heat stored in the earth. This cost effective and sustainable source of energy requires no fuel, and is therefore immune to fuel cost fluctuations.

Geothermal Energy: Harnessing the Heat Beneath Your Feet
Posted by radiant heat in Geothermal Heating on May 6th, 2010
Right below your feet is a source of renewable energy that is largely untapped. It heats groundwater by conduction and convection as it travels toward the surface of the earth. Lawrence Livermore National Lab scientists Carol Bruton and John Ziagos explain how geothermal energy can be used to generate electricity or heat buildings.
