Portion of letter of referral from another satisfied customer:
I wanted you to know how much my wife and I apprecciated the outstanding job you and your staff did in the installation of our Solar Hot Water system on our house... Now that the system has been installed a couple of months, and I have seen the economic benifits from my monthly gas bill, I can see that the payback will be a pretty short time period...

A Radco solar hot water heater in the Phoenix AZ metro area will provide a great return on investment, save energy, save money, reduce your carbon footprint with green solar energy. A solar water heater can be a power backup for utility system failures, and qualifies for Federal solar tax credit & Arizona State solar system tax credits.

If you have an old water heater that needs to be replaced, it usually costs less to install a new solar water heater as its replacement than to replace it with a new water heater of the same type. Help make America energy independent. Support our nations's Alternative Energy Initiative and buy an American produced solar water heater.

Every home has to have hot water, wouldn’t it be nice to heat it for free? With a Radco solar water heater you can!

The Radco solar water heater system is a 8-gallon closed circuit, which circulates water through a heat exchanger and the solar panel on the roof. The hot water from the solar panel heats the heat exchanger. The cool water in the water heater tank is then circulated through the hot heat exchanger and brought up to temperature for use in the home.

A solar water heater can produce more than 50% of the hot water requirements for a typical residential home (in the Phoenix AZ metro area it can be over 90%), qualify for APS solar rebates or SRP solar rebates, 30% Federal Solar Tax Credit (no maximum cap as of January 1st, 2009), and $1000 Arizona Solar Tax Credit.

Solar heating reduces water heating bills up to 50% or more and extends the life of your current hot water heater by dramatically reducing scaling. Solar systems add value to your home and protects against rising energy costs. Save money and the environment.

Qualifies for Federal solar tax credit & Arizona State solar tax credit. Exempt from Arizona State sales tax. No increase in your Arizona property tax assessment. SRP solar system rebates & APS solar system rebates. HOA approved. Ready for a change? Order your Radco Solar Water Heater Today!

DRAINBACK Heat Transfer Tank

Radco DBHX 6000 Series Drainback Heat Exchange Modules
Operates a solar water heating system by transferring solar energy to a storage water tank. The Radco DBHX 6000 series drainback systems have these strengths:

• Allows most any solar collector and water storage tank to   become a drainback system.

• Modular design translates to lower labor costs for installation   and less space requirements for installation.

• Provides automatic and fail-safe freeze protection.

• Works well in most climates.

• Power is not required for the drainback freeze protection to   work.

• Does not need propylene-glycol to protect from freezing   temperatures.

• Low maintenance - No need for propylene-glycol or rust-inhibitor   fluids translates to less maintenance requirements.

• The closed-loop to solar panels protect the collector's fluid   passages from mineral build up caused by "hard" water --where   water contains an excessive amount of dissolved minerals.

• SRCC approved designs.


Heat Transfer Tank

Radco has developed a mechanical control package for drainback systems. This Drainback Heat eXchange module (DBHX) is a factory-assembled unit which provides:

• A single-walled heat exchanger

• Collector fluid reservoir

• Solar collector fluid circulator pump

• Hot water booster circulator pump

• Differential temperature controller unit.

All of these abilities are assembled into one attractive module.

Most any solar collector and any water storage tank can be combined to form a Drainback system.

Solar Energy Technology

Solar energy refers to the use of the sun's rays rather than electricity, oil, kerosene or natural gas to provide heat for a wide variety of uses. Sunlight strikes and heats an "absorber" surface within a "solar collector". The water to be used flows through the absorber that has been warmed by the sun and picks up the heat from it. An analogy is often made to a garden hose that sits in the Phoenix sun and then heats the initial water passing through it.

Solar Panel

For the heating of household water a flat panel is used that is made up of small tubes. The size and number of tubes as well as the material of the absorber effect how well the sun's warmth is captured and transferred to the water. (This is referred to as the thermal performance rating of the product.)

In addition to the solar panels, the other major parts of a solar heating system include the circulation system and the storage tank. For solar hot water heating systems, the hot water tank is the storage tank and in some situations (e.g., with gas solar hot water systems) an additional storage tank is required.
  • With many people now focussed on reducing their carbon footprint, there has been increasing interest in renewable energy. Arguably the best and most cost-effective way to do this is to install a solar water heating system.
  • A solar water heater is over 5 times more efficient at capturing the sun's energy and converting it to usable power than photovoltaic (PV) systems
  • Water heating accounts for a significant percentage of the total energy used in a typical single-family home. An electric water heater is one of the biggest energy users of all appliances in the home.
  • Solar energy is an environmentally friendly source of power and in the Phoenix metro area there is a lot of it.
  • A Solar water heater does not pollute. By investing in one, you will be avoiding carbon dioxide, sulphur dioxide, nitrogen oxides, and the other air pollution and wastes created when your utility generates power or you burn fuel to heat your water.
  • When a solar water heater replaces an electric water heater, the electricity displaced over 20 years represents more than 50 tons of avoided carbon dioxide emissions alone.
  • Solar energy provides an energy backup, enabling you to continue getting power even when utility electric power or natural gas supply is disrupted.
  • Lowest maintenance costs (minimal)
  • Longer lifespan due to fewer moving parts and no corrosion
  • Cleanest, safest and quietest source of energy
  • Lowest operational costs (energy is free from the sun)
Solar water heating systems are becoming more and more cost effective due to recent rises in energy prices. Depending on how much hot water you use, the system will generally pay for itself within 5 years in the Phoenix metro area. In addition, houses with eco-friendly features tend to stand out in the market and sell more quickly. You should notice an immediate reduction in your utility bills. Costs can be offset even further by government tax credits and utility rebates which will help people install a solar water heater. If you are looking for a way to reduce your carbon footprint and save money in the long term, solar water heating could be perfect for your needs!

Should I use photo electric panels to power my water heater?
Under average conditions, to get 15 kWh out of photovoltaics you would need a 3 kw system, batteries and inverters. At about ten bucks per watt that comes to $30,000. So cost of energy from the photovoltaic system is six times as high as that from the solar hot water system. Why would anyone put the former on their roof without the latter?

Why use a Solar Water Heater if I am installing PV Panels?
We use lots of devices to convert energy from one form to another. A gas boiler converts the chemical energy of the gas into heat energy to warm your home. A car engine converts the chemical energy of petrol, or diesel, into mechanical energy of motion. None of these energy conversions is 100% efficient, with the missing energy usually appearing as heat. Indeed, an ordinary light bulb only converts about 5% of the electrical energy into light and a typical car engine only manages to turn about 30% into movement. The more times you convert energy from one form to another the more of it is likely to get lost along the way. Solar Thermal uses the sun to directly heat water, which is why it is more efficient, cost-effective, and far more affordable than PV.

Solar Hot Water Systems have a much lower entry cost than PV Systems. Typically, the average household can install a Domestic Solar Hot Water System for under $8,000, offsetting more than 80% of their annual water heating costs, saving you hundreds of dollars. To match these savings with a PV System, an initial investment of tens-of-thousands of dollars would be required, not to mention applications for net metering and connection to the electric utility. There are no such requirements with Solar Hot Water Systems. Additionally, Solar Hot Water Systems make better use of the available roof space than a PV System. A typical Solar Hot Water System will produce the equivalent of 600 watts per square meter, while a PV System will produce only 100 watts in the same space.
Additional Solar Energy Resources

The National Renewable Energy Laboratory, provides a number of resources by which to learn more about solar energy and solar hot water heating systems for your home. They also offer the Renewable Resource Data Center which provides numerous resources on solar radiation including an extensive collection of renewable energy resource data, maps, and tools. There is also biomass, geothermal, solar, and wind resource data for locations throughout the United States.

Department of Energy
The US Department of Energy Consumer´s Guide to Energy Efficiency and Renewable Energy provides additional information on Solar Hot Water Heaters and Solar Swimming Pool Heaters.

The The Energy Improvement and Extension Act of 2008, signed by President Bush on October 3rd 2008, offers consumers and businesses federal tax credits beginning in January 2006 for purchasing fuel-efficient hybrid-electric vehicles and energy-efficient appliances and products. Most of these tax credits remain in effect through 2016.

Consumers who purchase and install specific products, such as energy-efficient windows, insulation, doors, roofs, and heating and cooling equipment in the home can receive a tax credit of up to $500 beginning in January 2006.

The EIEA also provides a credit equal to 30% of qualifying expenditures for purchase for qualified photovoltaic property and for solar water heating property used exclusively for purposes other than heating swimming pools and hot tubs. The credit shall not exceed $2000.

As of January 1st, 2009 - No maximum cap on the 30% credit !

Improvements must be installed in or on the taxpayer's principal residence in the United States. Home improvement tax credits apply for improvements made between January 1, 2006 and December 31, 2008 2016.

The Database of State Incentives for Renewables and Efficiency website provides a searchable comprehensive database of state, local and utility based incentives.
