The best and most concise info we found on the web is at http://www.epsea.org/mass.html And, yes it can be incorporated into the PyramoduleTM as the sketch on this website will show.

If you live in a region that has long cloudy spells, a backup heater will be needed. The system could still be economically practical if it is reasonable in price. A quality solar heating system will pay for itself many times in energy savings and tax credits may apply. A solar system must not detract from the architecture of the building or it will lower real estate value. Click here for more information.

Thermal mass is the ability of a material to retain heat. The thick walls of an Earth Block building create thermal mass, protecting the occupants from extreme temperatures with a building that stays cool in the summer and warm in the winter. Heating and cooling requirements in an Earth Block building are substantially reduced in an Earth Block home.

We will refer your enquiry to a one of our installation engineers who will contact you to offer you a no-obligation quotation after surveying your home. The engineer is not a salesman and will not seek to pressure you into buying. We do hope, however, that you will only ask the engineer to call if you are seriously interested in our solar power systems.

Rear fill" refers to the presence of depth and ambiance in music. A properly designed system using two channels will reproduce original rear fill on the source without rear high frequency drivers. Since recordings are made in two channels, that is all you will need to reproduce it. What is captured at the recording session (coincident pair mics, Blumlein mic patterns, etc.) by a two channel mic array will capture the so called rear fill or ambiance.

Yes. Just be sure that you drink more water and add vitamins to your daily diet as you will be perspiring in each sessions and you will need to replace your vital minerals and vitamins. Yes. By allowing a little moisture on your skin, your skin is protected from dehydration and skin dryness after your daily or occasional thermal session.

Great question! We hear this all the time and it is why the Sierra meter is such a popular a choice by scientists and technicians “in the know”. Sometimes the pressure based flow transducers are called Volumetric or Mass Flow Meters. A pressure based meter is essentially a "Volumetric" device with the addition of the corrections required to compensate for the flowing gas, pressure, temperature and other second and third order effects.

While it is true that solar energy is "free" - the cost of heating a swimming pool by this method is not free! There are several issues which must be considered. The solar panel location should be North facing with approximately 25 degree inclination. The panel area should equal the pool area. A Pump is necessary to raise the pool water to the panel system, and ideally a temperature differential set-up to tell the pump when to start (and stop).

Buy a system that has been tested and certified by either the Solar Rating and Certification Corporation or the Florida Solar Energy Center. Get details from the contractor on the warranty for the system - what it covers, how long it is in effect and where you can get parts and support. Be sure the installers are licensed solar contractors with good references. Contact some of their customers and make an appointment to look at the installations.

No. A Solar Heating System for your pool is a closed system that re-circulates the water in your pool. Solar Systems for domestic hot water needs are completely different and separate.

Currently approved solar heating systems for pools are trellis structures incorporating pipes or flat laying panels. Committee approval must be granted for all solar installations.

A pool cover prevents evaporation loss, particularly at night. The cover traps the solar heat that has been added during the day. This is very complementary to the solar system. The solar system can be viewed as actively adding heat. The cover retains that heat passively. [Top]

With the increasing costs of energy and a desire for environmental friendliness, some customers are turning to the sun as a way to heat their domestic water. While Bradford White Corp. does not manufacture complete solar heating systems, Bradford White does manufacture a solar water heating storage tank for use with solar systems. This tank takes the heated water from the solar panels and uses it as a heat source instead of conventional gas, oil or electric heat sources.

Whether the connecting pipes are properly and adequately insulated, otherwise the hot water will cool as it travels along the un-insulated pipes. The insulated pipes must be covered with aluminum cladding. If there is any denting or damage, attend to it. For leakage in the storage tank, collector, distribution pipeline and the hot water faucets in the home. This may be the cause for inadequate hot water. Contact the manufacturer, as all leakages must be stopped immediately.

Yes, under normal circumstances. An additional storage tank will be required to be installed to pre-heat the cold water prior to entering the existing tank.

Solar (sun) radiation travels to earth by electromagnetic waves at the speed of light (186,286 miles per second or 300,000 kilometers per second). The electromagnetic spectrum carries different kinds of rays (gamma, x-ray, visible, infrared, etc.) each with a different wavelength between 0.1 to 150 micrometers long (a micrometer, μm, or a micron is one millionth of a meter) and each with its own frequency.

This has been determined in laboratory tests. We have test results from public sector as well as private sector laboratories with test conditions and results. The latest one is a consolidated test report prepared by the Department of Mechanical Engineering at the University of South Carolina. a) By measuring temperatures before and after the application, one will quickly realize that an ASTEC roof is much cooler than an 'ordinary' roof.

A solar system consists of a solar collector, a regulator, a multistage pump and a very good insulated hot water tank. The collector on the roof collects the energy from the sun with its absorbers and transfers it via a solar medium (glycol MH – the non-poisonous type). The heat is transferred through copper pipes into the solar storage tank. The solar station with its built-in regulator transports the heat via a heat exchanger, into a solar storage tank.

A well-planned and well-designed solar system can give a maximum of 70% saving on water heating during a year. From about May to the end of October, it is possible for a solar system to cover 100% of all hot water needs. For the remainder of the year, a reduced output is expected. The cold water supply, however, will be preheated and the rest of the hot water will come from the existing method of water heating that we can supply, without any loss of comfort.

Businesses that use large quantities of hot water can experience dramatic cost savings by going solar. Laundromats, apartment buildings, restaurants, factories and hotels are examples of some of our most satisfied customers. Many of these businesses use the majority of their hot water when the sun is shining and are ideal for solar.

Solar is simple, fully automatic, completely reliable and requires no regular maintenance for 20-30 years. It is possible that you may need a service call over that time, but there is no need to change the fluid, clean the panels, or oil the pumps. We have been in business for 30 years and the majority of our systems from the 1970s and early 1980s continue to harvest the sun at peak performance. We offer a:

The best solar systems (Thermomax, Filsol, AES etc.) can be expected to last 25 years or more. Thermomax use marine-grade stainless steel for external components, and 30+ years may be possible. They will pay for themselves, with many years of free energy to follow.

A Solar Thermal system can provide as much as 70-80% of your hot water needs for the year, greatly reducing the portion of your utility bill that relates to water heating -- usually natural gas. A full-size system will typically provide all the hot water needed between March and October. Beginning in 2006, a federal tax credit equivalent to 30% of the cost of installation will be available for each system placed in service (with a $2000 cap for residential systems).

A solar thermal collector, often referred to simply as “a collector”, is a device designed to receive solar radiation and convert it into thermal (heat) energy used to heat water. Generally, a collector is composed of a sturdy frame, an absorber (heat absorbing panel with channels for the water or a heating fluid), glazing (protective sheet of glass or plastic) on the sun-facing side, and insulation on the back and sides.

Yes, it is usually the most cost effective method for heating your home. This can be done in interface with a regular forced air furnace, or with a boiler for radiant floors or baseboard heat.

Solar thermal or solar hot water (sometimes referred to as “solar domestic hot water” or SDHW) is a water heating system that heats water within units called “solar thermal collectors”, either directly with sunlight or by heating a “working fluid”, such as glycol, that then heats the water. These flow to a hot water heater, which is to be used as a storage tank and for back-up heating at night or during the cold months of the year.

There are many different types of solar energy conversion systems. The two most economical, technically advanced, and easy to use are solar thermal for space and water heating, and solar electric for electrical energy generation.
