The building expansion is required to meet forecasted growth for its cross-linked polyethylene tubing in plumbing, fire sprinkler, radiant heating and cooling and hydronic piping systems used in residential and commercial buildings.

The 24,037-sq.-ft. educational facility achieved 62 points out of a total of 79 possible points for LEED Gold -- including 8 out of 11 points for optimization of energy performance.

Girl Day is an annual celebration of girls’ interests and aptitude in science, engineering, technology and mathematics (STEM) education and potential in STEM-related career fields.

 

A dedicated website will feature information and activities relating to geothermal along with an educational video and interactive children’s activities.

A designer needs to tie in an indirect water heater to a multiple boiler system. He selects a hydraulic separator for the project and connects the piping of the indirect water heater on the same side as the boilers.

The designer’s intent was to supply a low-temperature floor-heating zone, as well as a higher-temperature baseboard zone and air handler, from a thermal storage tank heated by a pellet-fueled boiler.

An installer sets up a zoned distribution system. To keep it simple, he uses the same size piping for the headers and all the distribution circuits. The heat source is a low-mass copper tube boiler with high flow resistance.

Trends show the market for solar combisystems — systems that provide both domestic water and space heating — has potential to expand. An estimated 42,000 of these systems are installed in the United States, and the market is growing slowly.

An installer who is used to boiler replacements may view the mechanical room aspects of changing from a boiler to a geothermal heat pump the same as a boiler changeout; just swapping out one “box” for another. Unfortunately, this can lead to some significant operating problems.
