Buderus solar is one of the largest and most reputable manufacturers in the world. They have been manufacturing and designing solar water systems for over 25 years, and continue to invest in research and development to bring innovative, high quality, solar products to the market.
A Buderus solar thermal system for hot water consists of a solar collector, a pump station, and an indirect hot water storage tank. The solar collector, which is located on the roof, collects the sun’s energy and transfers the heat to the storage tank via the tanks internal heat exchanger. The storage tank in turn allows the hot water to be stored until it is used. The controller activates the system’s pump when there is enough solar energy to create hot water. Even on a cloudy day, light penetrates the cloud layer and heats up the solar collectors.
An existing Buderus wall hung or floor standing boiler can be combined into the solar system as a back-up for domestic hot water. The solar system can also complement the boiler for space heating by reducing the number of boiler starts, saving on costly fuel.
A typical Buderus residential solar hot water system using 2-4 collectors takes about 1-2 days to install depending on location and roof type. Larger commercial systems take longer because of the scale, equipment, and labor required. The typical life expectancy of a Buderus solar hot water system is 20-30 years. If the system is properly maintained, it can last over 30 years. Every 5 year, the heat transfer fluid should be checked and replaced. The pipe insulation and controller settings should also be checked as part of the annual system check-up.
A residential solar water heater will offset greenhouse gas emissions by about 1,600 pounds of carbon dioxide (CO2) per year. That’s equal to the amount of CO2 released by an average vehicle every 1,700 miles!
BALTIMORE – In an atmosphere that some said felt like the original Continental Congress of 1776, Oilheat leadership from Maine to South Carolina stood one at a time to set the industry on a new cleaner, greener and more sustainable course. The historic collaboration assembled oilheat associations and stakeholders to formally adopt long-term goals, including expanding Bioheat®.
“It is an exciting time for the industry,” said Peter Carini of Champion Energy of New York. “As an industry, we face many challenges, but most of them can be met if we embrace this exciting opportunity to create a new product that will be environmentally responsible and competitive, ensuring that our industry will be a part of the solution to the energy security and climate change challenges that face our Nation.”
Primarily used as a transportation fuel, biodiesel, which is already ultra low sulfur, can be blended with regular No. 2 heating oil or low sulfur heating oil. Blends of biodiesel and heating oil are called Bioheat. Bioheat offers a seamless way to reduce emissions and move to a cleaner burning home heating option.
At the national oilheat industry policy summit, oilheat leadership including National Oil Heat Research Alliance, the New England Fuel Institute, and Petroleum Marketers Association of America approved a statement formally embracing cleaner burning fuels, like Bioheat, as well as endorsing an ultra low sulfur standard and solar technology. The resolution calls for changes to heating oil, including that by July 2010, all heating oil will be mixed with a bio component to ensure that at least 2 percent of the fuel is renewable, with goals to increase levels over time.
“Bioheat is another way biodiesel is working to reduce our dependence on foreign oil, to seamlessly introduce cleaner fuel alternatives and to implement sustainable energy solutions,” said National Biodiesel Board CEO Joe Jobe. “We applaud the oilheat industry for formally recognizing the outstanding potential for Bioheat and biodiesel as an important part of our country’s energy future.”
The Bioheat market, at a 5 percent blend, has the potential to increase demand for biodiesel by 450 million gallons annually. Nationally recognized institutions such as the Brookhaven National Laboratory, US Department of Energy’s National Renewable Energy Lab, Massachusetts Oil Heat Council, Abbott & Mills Oil Company, NOCO, New York State Energy Research and Development Authority, (NYSERDA) and NORA have thoroughly tested Bioheat.
Results have demonstrated blending home heating fuel with biodiesel, Bioheat fuel, is seamless and transparent to the heating oil network and works in home and commercial heating systems with no adverse operational characteristics. Some of Bioheat’s benefits include:
