If the loan is not a secured debt on your home, it is considered a personal loan, and the interest you pay usually isn't deductible. Your home mortgage must be secured by your main home or a second home. You can't deduct interest on a mortgage for a third home, a fourth home, etc.VERVIEW. If you're a homeowner, you probably qualify for a deduction on your home mortgage interest. The tax deduction also applies if you pay interest on a condominium, cooperative, mobile home, boat or recreational vehicle used as a residence.
A gas heating system is less expensive to operate than an electric unit. Natural gas is a cheaper form of energy than electricity and over the past few years, the cost of natural gas has actually decreased. However, a gas-powered unit will require a larger initial investment than an electric unit.Gas heating systems generally heat the home faster than electric units.atural gas is a cheaper form of energy than electricity and over the past few years, the cost of natural gas has actually decreased.

A furnace works by blowing heated air through ducts that deliver the warm air to rooms throughout the house via air registers or grills. This type of heating system is called a ducted warm-air or forced warm-air distribution system. It can be powered by electricity, natural gas, or fuel oil.Inside a gas-or oil-fired furnace, the fuel is mixed with air and burned. The flames heat a metal heat exchanger where the heat is transferred to air.he best gas furnaces and boilers today have efficiencies over 90%. The efficiency of a fossil-fuel furnace or boiler is a measure of the amount of useful heat produced per unit of input energy (fuel). Combustion efficiency is the simplest measure; it is just the systemâs efficiency while it is running.
