For the most part, selecting the right heating equipment is generally determined by the ease of access to fuel such as natural gas, propane gas and electricity. Over the years, the rising cost of energy has also become a determining factor. Finally, local climate conditions will play a role as well. Forced air gas furnaces are generally preferred in climates where the weather is severe. However in regions with mild temperatures that rarely reach the freezing point, a heat pump can be a feasible substitute.

Furnace efficiency is measured by its Annual Fuel Utilization Efficiency (AFUE) rating in percentage, which is a federal standard intended to offer end users a simple way to compare different brands and models of furnaces. The rating itself shows the percentage of fuel that is converted to useful heat energy during the combustion process. For instance, a furnace that has a gas input of 100,000 BTU (British Thermal Unit) and a 90% AFUE rating utilizes ninety percent of its total gas input and exhausts only ten percents waste gas. This rating also applies to other gas appliances such as boilers and water heaters.

On the other hand, a heat pump provides both heating and cooling from the same equipment. As an alternative to burning fuel to generate heat, the refrigeration cycle absorbs heat energy from the outdoor air even at lower temperature and transfers it into the indoors. This process is best described as the opposite of how a normal air conditioner works by removing heat from where it is least wanted and dump it to a place where it makes little or no difference. The efficiency of a heat pump is determined by its Heating Seasonal Performance Factor (HSPF), which is a calculation that weighs heat output relative to the electric power that is consumed. A higher HSPF rating is indicative of a more efficient piece of equipment.

New Furnace or Heat Pump Installation

It’s imperative that when installing a new gas furnace complete set of load calculation is considered to establish the load requirements for every room in your home. While it’s not an unusual practice to equate the rating of existing equipment, the calculated load of an entire house provides an adequately balanced air distribution and temperatures throughout the living spaces.
