The Enviro-Pak Heat Recovery Water Heater is connected to a water heater and an air conditioner, or refrigeration compressor. The excess hot waste gas is diverted through our vented double-wall heat exchanger, where it safely and efficiently heats domestic hot water dramatically reducing the use of the existing water heating system. Enviro-Pak also delivers longer compressor life and greater A/C or refrigeration system efficiency. Because Enviro-Pak returns the hot gas to the cooling system at a much lower temperature, the compressor doesn’t work as hard to cool it. The system draws less power, and work load is reduced-increasing efficiency by as much as 3 SEER. Enviro-Pak is ideal for residences, businesses, industry and any establishments where AC (1.5-5 ton) use occurs most of the year. Earthday.net has calculated that 42% of household energy costs go toward heating and cooling and another large percentage is used to run the hot water heater. This kind of unit would make it possible for anyone, including business and industry, to make their AC or refrigeration system immediately run more efficiently while it heats the water for showers, washing or any hot water use. ENVIRO-PAK is also perfect for retrofit projects and for consumers looking reduce their carbon footprint and save money. The typical payback can be from less than a year to 3 years.   ENVIRO-PAK houses our patented TRU-TWIST twisted tube technology, making it more efficient than any HRU previously available. Because of its compact size, one is able to tuck it under the arm and carry it to any building site. Provides free hot water Increases air conditioning & refrigeration efficiency Small footprint for applications up to 5 tons Fully insulated vented double-wall heat exchanger. Controls and pump mounted and wired for simple installation Isolation valve kit available for water and refrigerant connections Powder Coat CRS Steel (Stainless steel also available) enclosure for long life and durability Indicator lights for operation and safety diagnostics Whisper quiet operation Low pressure drop through water side of heat exchanger Compatible with R-22 and Ozone-friendly HFC-R410a air conditioning refrigerant and R-134a for refrigeration systems High limit and freeze-stat controls Factory assembled and packaged 5 year limited warranty on heat exchanger Assists in meeting LEED goals ETL , CSA listed, UL approved WARRANTY: These new boxed units have a 5 year warranty on the heat exchanger. MOUNTING/LOCATION: ENVIRO-PAK Heat Recovery Units are for both indoors or outdoors and may be installed in any conditioned area where the unit is not subject to freezing temperatures such as basements or laundry rooms. They must be mounted vertically and located higher than the condensor for proper drainage in the offcycle.  All models contain a water high limit control factory set at 155 F to prevent scalding and are equipped with freeze protection.     CIRCULATOR PUMP: ENVIRO-PAK Heat Recovery Units contain a low wattage direct drive single stage circulator with replaceable cartridge. Standard Models use a Taco 006 series circulator. This pump has the highest reliability in its class and its self lubricating feature with no mechanical seals makes it practically maintenance free. The pump has patented (Patent # 5664939) internal flow check (IFC) system which prevents reverse or gravity flows. This eliminates the need for external in-line flow check and also helps in improving the system performance. This UL listed circulator delivers flow to 9 GPM and head to 9 feet with 3250 RPM, 0.025 HP, 230/50-60/1. PERFORMANCE RATING: At standard operating conditions (e.g. R-22, 275 psig discharge pressure, 90°F entering water temperature) the unit will produce 8-10 gallons of hot water per ton per hour of compressor run time. The performance rating of the unit is as per ARI-470:2001 standards. The UL listed heat exchanger can be used for R-22, R-134A, R-500, R-502 and R410A refrigerant.
