Taco is pleased to announce the latest addition to our online educational program for members of the FloPro Team it's a 4-part series on designing and installing Mutli-Temp, Multi-Load Hydronic Heating Systems.In this presentation, you'll learn how to best pipe, wire and control a system requiring multiple temperatures and multiple loads. You know, one of those jobs. This real world presentation gives you practical, easy to understand solutions for challenging systems. The focus is on putting together a system that is simple, understandable and repeatable, which in turn puts money in your pocket.You'll near the dynamics of primary-secondary piping for cast iron boilers, and "moose-antler" piping for modulating-condensing boilers. You'll learn how to best control different water temperatures using everything from simple tempering valves, to motorized mixing valves, to variable speed injection mixing."Multi-Temp, Multi-Load Systems" is the third addition this fall to the "Videos" section of the FLOPROTEAM website. ...

Viessmann Group, Allendorf/Germany, one of the leading international
manufacturers of heating systems, says that 13.6 million old heating
systems need to be replace by 2020 if Germany wants to reach its
climate protection targets. To date only
600,000 heating systems are replaced every year, according to
Viessmann. A company spokesperson said the heating sector with its
share of 38% of the total German energy consumption (electricity: 21%,
transport: 28%, other sectors: 13%) would be given too little
consideration in the climate protection debate. (source)

The European Union and its Member States have committed themselves to
achieving a 20% share of renewable energy in Europe's final energy
consumption by 2020. As only three renewable sources (biomass,
geothermal and solar) generate heat, it is crucial to clarify how these
different sectors can contribute to the renewable energy target. A new
study being released this autumn – Study of the Potential of Solar
Thermal in Europe, which has come from two Austrian bodies (AEE –
Institute for Sustainable Technologies and Vienna University of
Technology) examines the growth that can come from solar. (continue)

Organic rankine cycle using Honeywell’s 245fa refrigerant turns heat from
solar panels into electricity
MORRIS TOWNSHIP, N.J., Oct. 28, 2009 – Honeywell (NYSE: HON) announced
today that its Genetron® R-245fa refrigerant is being used to help homeowners
generate electricity from the sun’s heat while offsetting energy costs.
Honeywell’s energy-efficient refrigerant is being used in an organic rankine
cycle (ORC) called the 35Z Micro Power Plant, manufactured by Germany-based
Turbolina GmbH & Co. KG. The 35Z Micro Power Plant has a unique design that
uses water heated by thermal solar panels to evaporate the refrigerant, which
in turn drives a turbine to generate electricity. Because no fuel is burned to
create the electricity, the unit does not produce any carbon dioxide emissions.
The remaining heat from the 35Z can be used to supply heating and hot
water. (continue)
