“RESOURCE SAVER” DISHWASHER (MODEL GU3600XTV) MANUFACTURER: WHIRLPOOL
D
ishwashers are a technology that has made great efficiency leaps thanks to computerized controls and innovation. They’ve become quieter, “smarter,” and
much more miserly about water use. Whirlpool’s latest top-shelf dishwasher raises the bar
once again. What we like about the product isn’t simply the Resource Saver wash technology developed by Whirl- pool, which employs care- fully managed use of water jets and adaptive cleaning cycles, but also the durability engineering. It’s designed for lifelong performance, with a stainless steel interior and rugged and flexible trays. Based on a typical dish-
washer made before 2000, the Whirlpool Gold uses one- third the natural resources to
do the same job. www.whirlpool. com/catalog/category.jsp?cat=108

While the efficiency of most appliances has improved dramatically over the past decade, dishwashers have been among the most improved. Models such as the Whirlpool product featured demonstrate that even greater improvements are both possible and essential.

QUIK TRAK RADIANT PANEL SYSTEM MANUFACTURER: UPONOR
T
he concept behind Quik Trak panels is simple. It’s a ready made system for installing radiant heating. If you’ve been debating whether adding radiant heat is practical in a ret-
rofit job, this product helps bring the cost and complexity down. Quik Trak consists of plywood panels 7” wide x 48” long x
½” thick, attached to an aluminum transfer sheet. In the center of each panel is a groove designed for 5/16
” Wirsbo hePEX plus
tubing. The panels are installed staggered, similar to a hardwood floor, and the line includes return panels that allow you to run the tubing as a continuous loop. The system is less resource and labor intensive than in-slab radiant systems, and also has a faster response time. Because the system is so
lightweight and low profile, it can also be used as a wall heating system, an interest- ing option for bathroom remodels.

RADIANT HEATING: HOW IT WORKS
In an efficient hydronic radiant floor installation, a manifold separates heated water into different zones by way of independently controlled valves that are part of a central manifold. (Illustration:
