(NC)-Experts agree that few homeowners know their rights when it comes to door-to-door water heater sales.

EnerCare Inc., a leading provider of energy efficient products and water heater rentals, answers a few commonly asked questions on ways homeowners can protect themselves from fraudulent door-to-door water heater salespeople:

What are the warning signs that I might be dealing with a fraudulent water heater sales-person?

When a salesperson says they are from your current water heater provider, utility or local municipality, ask for identification. Organiza-tions such as Enbridge, Direct Energy and government agencies do not promote the exchange of water heaters door-to-door. If a salesperson claims they are working on behalf of one of these agencies, chances are it is false.

What steps can I take when first approached by someone trying to sell me a water heater?

Remember that you don't have to let the salesperson into your house. You have a right to ask for identification and to verify their identity by calling their employer. If the sales-person becomes rude or pushy, ask them to leave.

What are some things I should consider if I am interested in buying a water heater from a door-to-door salesperson?

Never feel pressured into signing a contract right away and always ask to keep marketing material and contracts for review.
