My Hot Water heating systems sounds like water is “burbling” through it .. what gives?

Now that Heating System is here, when my system turns on, I hear water running throught the pipes. The HVAC guys have been here to bleed the system (they did it 3 times yesteraday morning) and it still sounds like water is rushing through the pipes … its not constant though …seems worse for the 10-20 seconds after the circulator kicks in. I have a relatively new system with an automatic fill and an automatic air purge. At this point, I’m wondering if I should just let it run a while .. we do get good heat … maybe it takes a while for the system to “stabilize” after being off for 1/2 year? Its driving me crazy —sounds like a leaky toilet at times.

Sounds like you still have some air in the system, as long as you are getting heat, let run and it should take the air out.

A Handbook on Low-Energy Buildings and District-Energy Systems: Fundamentals, Techniques and Examples $290 Winner of Choice Magazine – Outstanding Academic Titles for 2007 Buildings account for over one third of global energy use and associated greenhouse gas emissions worldwide. Reducing energy use by buildings is therefore an essential part of any strategy to reduce greenhouse gas emissions, and thereby lessen the likelihood of potentially catastrophic climate change. Bringing together a wealth of hard-to-obtain information on energy use and energy efficiency in buildings at a level which can be easily digested and applied, Danny Harvey offers a comprehensive, objective and critical sourcebook on low-energy buildings. Topics covered include: thermal envelopes, heating, cooling, heat pumps, HVAC systems, hot water, lighting, solar energy, appliances and office equipment, embodied energy, buildings as systems and community-integrated energy systems (cogeneration, district heating, and district cooling). The book includes exemplary buildings and techniques from North America, Europe and Asia, and combines a broad, holistic perspective with technical detail in an accessible and insightful manner.

A Solar Buyer’s Guide for the Home and Office: Navigating the Maze of Solar Options, Incentives, and Installers $14.95 Solar power, once a fringe effort limited to DIY enthusiasts, is now fast becoming mainstream. Many home and business owners are curious about solar electric and solar thermal systems, and wonder how to go about getting a clean energy generation system of their own. The vast majority will hire a professional installer to do the job. But what should they be asking of these installers? What system makes the most sense for their home or office: solar electric, solar hot water, solar heating, or some combination of these?A Solar Buyer’s Guide for the Home and Office explains the options so that property owners can make the right choices both for their energy needs and their financial security. Understanding how solar power systems work will enable readers to be informed customers when dealing with professional installers-the book also provides advice on how to select a qualified installer and understand the expanding variety of tax credits and other incentives that are popping up around the country.The market for solar systems has been growing at an exponential rate and strong tax credits ensure continued growth even in a sluggish economy. Many of those who would like to catch this undeniable wave of the future are held back by widespread confusion. A Solar Buyer’s Guide for the Home and Office clears the air, allowing property owners to move forward with confidence to make their homes and offices more comfortable, environmentally sound, and secure against wild swings in energy prices.

An Investigation of Pv Powered Brushless DC Motors for Solar Pumping – An Autonomous and Elegant Integration of Electric Motor and Pump for Use with $76 Typical solar domestic hot water systems use a liquid working fluid to transfer heat from the solar collectors to the hot water storage tank. This book presents the results of a detailed investigation of a unique design and integration of electric motor and pump to circulate the liquid working fluid. The motor’s energy source is electricity that is generated from the sun by a photovoltaic module, creating an autonomous heating system. The design under review is a brushless DC motor that utilizes the magnet of a “mag-drive” pump as its rotor. This motor and pump technology, and integrated design results in both increased component utilization and increased reliability. The power switching devices of the motor perform commutation and maintain the photovoltaic module at the maximum power point. The pump magnet acts as the magnetic coupling and the motor rotor. Increased reliability is achieved through the use of solid state power electronics for commutation and the replacement of a dynamic pump seal with a static O-ring seal. This investigation reviews each major component’s characteristics under a variety of conditions to identify appropriate design choices and areas for improvement.
