What are the furnace rating?

sometimes known as the efficiency of the fleet, the evaluation of the furnace concerns the less overall quality of specific brands or types of furnaces than the annual efficiency of the fuel use of available furnaces from the brand to brand and model to model. Evaluation of furnaces is basically a way to determine the comparative cost efficiency in terms of fuel use, each of the numerous models of domestic heating. The furnace evaluation is useful in comparing types, oil or gas, as well as brands and models of household heating systems.

The furnace evaluation is based on a comparison of two or more furnaces of different manufacturers based on measured fuel use of each furnace. This use is calculated by the annual efficiency of fuel use (AFUE). On the other hand, Pec B receives a 90%factor. Of course, this means that Pec B uses 90% of the fuel for heating the house and 10% waste. Pec B is therefore a more efficient furnace than the furnace and when it comes to the use of fuel.

although specificDomestic heaters may have a better furnace rating, fuel efficiency than others does not mean that they are the most durable or least expensive installation. In other words, although fuel -efficient, these furnaces with a higher rating may not be the best overall value on the market.

on 1. January 1992, however, the US Department of Energy (DOE) ordered to have an evaluation of furnaces for all household heating systems after this date have a minimum of 78%. Mobile home heaters must have a furnace rating of 75% or better. This is of course in response to the age of environmental protection NCY (EPA), as well as increasing costs and decreasing fuel reserves for home heating.

Gas boilers have been found to have a slightly better furnace rating on average than oil boilers. Oil boilers are better than non -data boilers. Hot air -forced furnaces are usually rated somewhat lower than either forced hot water systems or steamgroping.

Determination of a specific type, not to mention the specific brand of home heating system, is sometimes a difficult choice. The rating of the furnace helps homeowners to choose the best possible heater for money.
