VIESSMANN BOILERS
The name Viessmann stands for products of top quality and highest technological advancement in the heating and refrigeration industries. In thirteen production plants in Germany and abroad, Viessmann manufactures a comprehensive range of heating products comprising all system components required by today's progressive heating technology. The Viessmann concept of design-matched product components has, in fact, set the standard in the industry. The Viessmann Group is also one of Europe's largest manufacturers of walk-in freezers, refrigerators, and coolers.
Viessmann boilers distinguish themselves through maximum operating reliability. Viessmann's double-wall sandwiched heating surface, which counteracts the formation of condensation and prevents corrosion damage, has proven itself in over a million installations.
Here are examples of Viessmann's quality design and construction.
The Principles of Comfort and Savings:
Weather-Responsive Controls and Low Temperature Boilers
by Stan Patey
When a heating professional comes to your home for a boiler replacement or when designing a new heating system, he or she must first determine the heat loss of your home. There are two ways that contractors try to determine heat loss. In a replacement situation some people try to measure the existing radiators or heating baseboards. Measuring the radiators makes the fatal assumption that the original heating contractor put in the exactly right amount of heating equipment.
A heat loss survey is a more complete and scientific calculation that considers the size of your home, the type of insulation in the walls, ceilings and floors, the type and size of our windows and doors. The last part of the equation is the temperature you want to maintain and the coldest temperature you could expect to have outside.

What does a Viessmann boiler cost?
It depends on when you measure , before it is installed or after its been installed and running.
For the homeowner, Viessmann is the best investment in the marketplace for many reasons. You pay more up front to get a lot back in return over time. Generally, an investment is just that way. The more invested the more returned.
For the heating professional, they get the ability to sell and install the best heating equipment in the world that gets installed without incident or callback.

How much will I save with a Viessmann boiler?
The answer to that is not found in just the comparison of the rating of one boiler to another. (The AFUE number.) There is so much more to system efficiency. AFUE (Annual Fuel Utilization Efficiency) is a testing method developed by the American boiler manufacturers that does not measure such significant variables such as: operation above 140 degrees F; accrual control method; delta T other than 20 degrees; boiler insulation (and its effect on standby loss on the boiler); length of burner cycle; presence of a sludge settlement zone; the ability to burn clean or proper sizing.
AFUE Testing Numbers This test is conducted in a laboratory where all tested boilers are run for 30 minutes to warm them up. Then only chimney losses are measured. The calculations which follow assume 8 minute firing cycles while running 140 degrees F out of the boiler and 120 degrees F back in. A "delta T" of 20 degrees. This is a condition that rarely, if ever, happens in the real world. Both the higher supply water temperatures and lower delta T values hurt efficiency. Both are common. Moreover, it is a fact that any combustion appliance takes several minutes to reach its steady state combustion efficiency. Few run that long in the field. Finally, the test ignores any and all losses of heat into the boiler room! If you pulled the insulation off the boiler, you would get a higher rating.
