Electric Insta Flow Tankless Water Heaters- BUILDING PRODUCTS Magazine (5/12/2009)
- Electric Insta Flow point-of-use tankless water heaters are 98 percent efficient, says the firm. Digital microprocessor technology controls the temperature of the water, and the temperature can be pre-set to prevent scalding without mixing valves. The units come in three capacities--Insta Temp, Insta Flow, and Insta Flow Micro--and are also available in a wide range of models to fit the desired application. 800-447-4962.
Gas Direct-Vent Tankless Water Heater- BUILDING PRODUCTS Magazine (5/12/2009)
- The RTG-66DV gas direct-vent, tankless water heater is designed for homes with two or three bathrooms. A concentric venting system simplifies installation by expelling the byproducts of combustion through a 3-inch exhaust pipe inside the 5-inch intake run. The unit can deliver water at a rate of 6.6 gallons per minute. The product uses natural gas or liquid propane. Energy factor: 0.82. 334-260-1500.
Tankless Water Heater- BUILDING PRODUCTS Magazine (5/12/2009)
- The Energy Star-rated N-0841MC tankless water heater yields 93 percent energy efficiency, versus 60 percent of a typical tank water heater, due to its Hybrid Super Heat Exchanger--a stainless and copper heat exchanger fused into one. The unit, which uses gas or propane, delivers up to 11.1 gallons per minute at a 35-degree temperature rise and 8.4 gallons per minute at a 45-degree temperature rise. Energy factor: 0.94. 877-986-6748.
- Greywater System
- BUILDING PRODUCTS Magazine (5/12/2009)
- The Clivus Greywater System includes a Greywater Dosing Basin as the collection point for all of a home's greywater. Made of rigid plastic, it contains level switches and an effluent pump or gravity siphon (where sufficient slope is available). When an amount of greywater sufficient to create a 11/2-inch flooding dose within the irrigation chamber has collected in the dosing basin, the pump (or gravity siphon) engages. Because the irrigation chamber is flooded throughout its length, water and nutrients are carried evenly to surrounding plants. 800-425-4887.
Gas-Fired TK-3 Pro Tankless Water Heater- BUILDING PRODUCTS Magazine (5/12/2009)
- The gas-fired TK-3 Pro is designed to withstand space-heating and domestic recirculation systems in residential applications. It starts heating water at flow rates as low as 0.5 gallons per minute, but it can generate an unlimited supply of hot water at a maximum flow rate of 7 gallons per minute. The unit measures 13.8 inches wide and weighs 40 pounds. It can be installed inside or outside and can be direct-vented. Energy factor: Natural gas: 0.827; LP: 0.833. 888-882-5244.
Tankless Water Heater- BUILDING PRODUCTS Magazine (5/12/2009)
- The R75Lsi delivers continuous hot water on demand up to 7.5 gallons per minute. The unit features a redesigned commercial-grade heat exchanger, an integrated condensate collector, an integrated digital temperature controller, and direct electronic ignition with no pilot light. The combustion unit is sealed, so it doesn't use interior combustion air. Two units can be connected together without a control board. The whole-house unit measures 10 inches by 14 inches by 26 inches and weighs 46 pounds. The temperature can range from 98 to 140 degrees. Energy factor: 0.82. 678-829-1700.
Tempra Electric Tankless Water Heater- BUILDING PRODUCTS Magazine (5/12/2009)
- The electric Tempra whole-house series comprises six tankless water heater models, from 12 kW to 36 kW, that can be installed in homes with one to four bathrooms. The smallest capacity unit has one heating module, the mid-range models have two heating modules, and the largest capacity units have three heating modules, which are all wired back separately to the electric panel. The temperature and flow sensors feed their readings into the water heater's microprocessor control; the microprocessor prevents the temperature from deviating from the set point. The tankless water heaters, which the company says are nearly 100 percent efficient, save 15 percent to 20 percent on water heating costs compared to a tank water heater. Energy factor: 0.99. 800-582-8423.
Series Four Electric Tankless Water Heater- ebuild (5/11/2009)
- The Series Four large-capacity electric tankless water heater is rated at 99 percent efficient. The whole-house unit features microprocessing temperature control. The flow activates each of the EX380T2T2's heating elements in stages based on hot water demand. Thermostatic control delivers unlimited hot water at precise outlet temperature. Energy factor: 0.99. 800-543-6163.
- Hybrid Air-Conditioning System Powered by Solar Energy or Electricity Reduces Energy Use 60 Percent
- ebuild (5/8/2009)
- DuCool is launching the DuHybrid air-conditioning system which is powered by solar thermal energy or electricity to reduce the energy required for cooling by up to 60 percent compared to standard air conditioning. The DuHybrid system combines desiccant dehumidification with evaporative or geothermal cooling to eliminate the need for conventional mechanical cooling. It utilizes solar thermal energy when available and automatically switches to electric power when needed. The DuHybrid system can also be integrated with a cogeneration system and can be powered by other renewable energy sources or waste heat.
Building Products Top 100- BUILDING PRODUCTS Magazine (5/8/2009)
- The need for product innovation doesn't stop in a down economy, and last year building product manufacturers continued to serve customers with plenty of new, valuable introductions for the home and the jobsite. And if Building Products' annual Top 100 list is any indication, contractors looking to differentiate and innovate welcomed that information.
