Tip & How-To about Heating & Cooling

Why are my equipment rating numbers important.

Rating numbers indicate the efficiency of heating and air conditioning equipment and are directly related to the amount of energy a specific model uses. The higher the rating, the more efficient the product, and the lower your heating and cooling bills can be. The federal government establishes rating guidelines and sets minimum efficiency levels. For cooling, the rating is SEER (Seasonal Energy Efficiency Ratio). For heat pumps, the rating is HSPF (Heating Seasonal Performance Factor). Gas furnaces are rated with AFUE (Annual Fuel Utilization Efficiency).

Riello 40 burner giving off black smoke,new pump and nozel installed same problem?


Black smoke indicates a lean burn - meaning that the fuel to air ratio is to great for optimal combustion. This will cause a soot condition in the heat exchanger very quickly and drop efficiency. Too much air will make the burn to lean. The oil burner technician will do a smoke test and adjust the air intake damper on the burner motor as part of an annual tune up that includes setting the amount of carbon dioxide, excess air, stack temperature, draft and more. Doing so will provide the most efficient transfer of energy in the fuel to heat your building and prevent premature failure of the burner and furnace. To do this properly, you need the right test equipment - it can not done by "eyeballing" it.

What size oil furnace is needed for 1200 square feet?


75000 to 85000 btu Or British thermal pound.
Two units of measure are important in sizing an oil furnace. The first is the British Thermal Unit or BTU, which represents the energy needed to raise the temperature of one pound of water by one degree Fahrenheit at normal atmospheric pressure. The input capacity of an oil furnace is often stated using this unit of measure. The second number is the fuel efficiency rating, which is expressed as a percentage. This represents the amount of energy that gets converted to heat, with higher numbers being better. To determine the energy output in BTUs per hour, multiply the input BTU by the efficiency rating. For example, a furnace with 100,000 BTU of input and an efficiency rating of 89 produces 89,000 BTUs of output. One with an efficiency rating of 80 and the same input amount, produces only 80,000 BTUs of output.

I have a RUDD UPNE-042JAZ. How many tons is that?


That is a 3.5 ton heat pump at 13 SEER.
A S.E.E.R. (Seasonal Energy Efficiency Rating) is the rating and performance standards that have been developed by the U.S. government and equipment manufacturer's to produce an energy consumption rating that is easy to understand by consumers. It has a universal formula and conditioning that can be applied to all units and compensates for varying weather conditions.

Basically, the lower the S.E.E.R. rating, the more energy (electricity) is required to produce the desired effect.
