A Comparison of SEER HVAC Systems

SEER, brief for Seasonal Energy Efficiency Ratio, is just a metric representing the energy efficiency of ac units. Adopted in 1979 and today prominently displayed on the Department of Energy’s yellow EnergyGuide sticker attached to each of new air-conditioning units, the SEER rating offers an at-a-glance means for consumers to comparison shop among different makes and models of cooling processes. SEER calculates the amount of heat energy extracted from a home at BTUs divided by the kilowatt hours of electricity consumed. Units are tested in a range of outdoor temperatures in 67 degrees Fahrenheit to 102 degrees Fahrenheit, and effects are averaged within the 1,000 operating hours believed to be typical for a 125-day annual cooling season. The higher the ensuing SEER numeral, the more energy-efficient the cooling function of this unit.

Central Air-conditioning

When SEER was adopted, the average rating for a central air conditioner was SEER 6. In the decades since, air conditioning technology steadily progressed, energy conservation awareness rose, and the SEER minimal conditions were revised. In 1992, federal law mandated a minimum SEER rating of 10 for all central air-conditioning units sold at the U.S.. In a revision issued in 2006, the minimum SEER rating was upped to 13. Central air conditioner using a SEER 13 score are considered standard efficiency units, while those using SEER 14 or over are classified as high-efficiency. The evaluations for high-efficiency central air conditioners top out about SEER 23.

Heat Pumps

A heat pump supplies both cooling and heating. When operating in cooling system, heat pump efficiency is rated by the SEER scale. As with central air, the identical national minimum SEER 13 applies to all heat pumps sold in the United States, and heat pumps with heat modes rated as large as SEER 24 are readily available. Efficiency of the heat function in a heat pump is rated by the HSPF, short for Heating System Performance Factor. Generally, heat pumps with higher SEER evaluations will even have high HSPF evaluations.

Ductless Mini-Splits

Ductless mini-splits utilize heat pump technology into state individual rooms without ports. The indoor component of a ductless mini-split system contains a compact atmosphere air handler containing a coil and compressor fan. The handler is linked by 2 refrigerant lines that stretch through an outside wall to an exterior casing which holds the compressor and outdoor coil. A single outdoor unit can serve up to four indoor air handlers in individual rooms. Unlike a central air-conditioning system in which one air handler accomodates the entire home and disperses cool air through ductwork, ductless mini-splits typically offer the highest available SEER, together with SEER ratings as high as 26.

Window Air Conditioners

Window air conditioners are rated by a simplified variant of SEER named EER, brief for Energy Efficiency Ratio. Like SEER, this figure expresses the power extracted from a home expressed in BTUs divided by the kilowatt hours of electricity consumed at one fixed outdoor temperature at one time. The calculation isn’t averaged over variable temperatures during a 1,000-hour cooling season (such as SEER is), thus EER is recognized as to be less accurate predictor of true efficiency in real world conditions. The federal minimum EER rating for window air conditioners is 9.8, and the most efficient available units offer EER ratings of just over 11.

How to Set a Water Softener to Regenerate

A water softener can remove hard mineral deposits in a home’s water source, particularly if the water comes from a well. Not only does the delicate water feel better on the skin, but soft water retains mineral deposits from building up in water heaters, washing machines and other household appliances, thus extending their usable life. You can set a water softener to regenerate at a specific time which best fits your family’s schedule.

Remove the lid and refill your water softener’s salt hopper with softener salt, then shut the lid to keep debris out of the salt hopper.

Have a sample of the difficult water before moving through the softening process to determine how much sodium your softener will require for each recharge cycle. If the test shows results in parts per million (PPM), then divide the PPM worth by 17.1 to determine the grains per gallon (GPG). Establish your water softener’s hardness dial (sometimes referred to as a brine control) to match the GPG figure determined by the water test.

Pull out the timer knob and set the present time on the water softener’s timer dial. Then place the time on the 24-hour regeneration dial when water is used in your family.

Determine the average quantity of water used daily in your family using the graph found within your softener’s operation manual. Then set the purifier dial up referring to the number of days between recharges dependent on the use chart.

Price to Replace a Boiler Circulator Pump

A circulator pump moves hot water through the radiators to heat the rooms, back into the boiler to be reheated of the household, in the heating . A circulator is made up of an electric motor coupled to a water pump, with the motor switched on when the thermostat calls for heat and turned away again as soon as the heating requirement was satisfied. Circulator pumps continue for several years but eventually will wear out and require replacement.

Replacement Price

Estimated costs of replacing a boiler circulator pump vary based upon the model and make of pump that your system demands and the quantity of labor involved with the replacement. Replacing a circulator pump can cost as much as $750 as little as $400 or more for the parts and labor in the time of publication. Price of the circulator pump itself drops based on the version your machine requirements.

Grants for Green Home Improvements

Green home improvements offer you an assortment of benefits to homeowners in addition. An energy-efficient home reduces spending and might make the home more attractive to prospective buyers, according to”U.S. News and World Report.” The federal government has initiated many different tax incentives and grants for green home improvements, as have state organizations and local energy firms. Funding for green home improvements is very likely to last, as energy-efficient technology and products continue to emerge.

Energy Star

Energy Star, a program supplies home improvement grants in the form of a tax credit. Consumers who purchase appliances receive a tax credit of 30 percent of the overall cost. Consumers who install solar power systems, small wind turbines, geothermal heat pumps or fuel cell systems receive 30 percent of the overall cost, with no limitation on the return. Although grants for new utilities like biomass stoves, heating and air-conditioning units, insulation, roof, doors, windows and water heaters die in December 2010, additional programs continue till 2016.

California Energy Commission

California residents are entitled to receive home improvement financing from the California Energy Commission’s Emerging Renewables Program. The grants are especially geared toward solar power, and provide financing for installation of wind or fuel cell electricity systems. The grants are available to consumers, as well as colleges properties and companies. For fuel cell systems, consumers receive a $3 rebate per watt. For solar wind systems, consumers receive a $3% rebate before April 6, 2011, at which point the rebate declines to $2.50 per watt. For solar wind systems that exceed 10 kilowatts, consumers receive a $1.50 per watt .

Southern California Gas Company

The Southern California Gas Company delivers green home improvement rebates to homeowners who upgrade home appliances with energy-efficient products. Qualifying products include dryers and dishwashers, low-flow showerheads, insulation, furnaces and water heaters. Grant amounts vary by product, ranging from $15 to get an energy-efficient showerhead to $200 to get a new furnace. All appliances must meet with the qualifications of the Energy Star program. Southern California Gas Company also supplies improvement programs for low-income renters and homeowners under the Direct Assistance Program.
