Frequently asked questions
Question: How efficient is the fireplace? 
Answer: Dimplex fireplaces are 100% efficient. All of the energy supplied to the unit is converted into heat, which stays in the room to keep you warm.* 
    *Many gas fireplaces advertise 70-80% efficiency. This means that 20-30% of the energy supplied to the units is vented outside. 

Question: Is it expensive to operate? 
Answer: No! Your Electric Fireplace operates for pennies a day. The flame uses slightly under 300 Watts of power. With an average electricity rate, the unit operates for a remarkable 2¢/hr providing all the ambiance and romance of a fireplace. When you choose to activate the heat feature, the total cost to operate the flame and heater is approximately 7¢/hr** (gas fireplace manufacturers regularly advertise running costs of 17¢/hr)!     
     **Electricity rates vary. 7¢/hr based on heater cycling at 50%. 

Question: Can the fireplace be easily relocated? 
Answer: Yes! Unlike gas fireplaces, which require venting fuel pipelines, your fireplace just needs to be unplugged and re-hung on the wall! When you need a change you can move it to a different room and when you move to a new home you can take your investment with you!

Question: The flame looks so real. How does it work? 
Answer: Dimplex has developed a patented technology which provides a realistic, wood-burning flame.

Question: Will the fireplace provide warmth and comfort in any room - large or small? 
Answer: Dimplex fireplaces distribute a warm, gentle, even heat over a wide area by means of a silent fan-forced heater. It will produce about 4198 BTU of total heat.# So, working in conjunction with the home's primary heating system, your fireplace is capable of taking the chill off just about any size room when required. 
    # Most gas fireplaces produce over 20,000 BTU of heat in a single room while the average size home requires only 90,000 BTU to heat the entire house. 

Question: Will the flame operate without heat? 
Answer: Yes! The flame and heater operate independently of each other. This means you can enjoy the ambiance of a realistic flame all year round!# #  
    # # In many gas units, the flame cycles off as the room temperature rises and you lose the flame effect until the room cools down again. In smaller rooms, gas fireplaces can be off a lot of the time and in the warmer climates they may not come on at all unless the thermostat is set higher than the room temperature. 

Question: Is it safe? 
Answer: Your fireplace has full electrical certification throughout North America for complete peace of mind. To ensure the safety of your family members, no combustible energy sources are used to produce the flame. This means that you never need to worry about oxygen depletion or carbon monoxide poisoning in your home and the glass remains cool to the touch to ensure children don't burn their hands on the glass. It also does not contribute to indoor moisture or mold concerns. Other features include impact resistant safety glass and safety cut out with reset controls. 

Question: Is it easy to maintain? 
Answer: Yes. Every 2 to 3 years the light bulbs, readily available at any hardware store, will need to be replaced. You should be able to do this easily yourself.^
    ^Most other fireplaces require ongoing, costly maintenance, which must be performed by qualified service technicians. 

Question: Can I install it myself? 
Answer: Yes! Just plug it in and hang it on the wall! Your fireplace plugs into any standard 120-volt outlet and does not require a dedicated circuit. It's as easy as plugging in a lamp and hanging a picture! In addition, your fireplace does not require any venting pipelines for fuel or expensive professional reconstruction to your home. Installation is fast and easy! 

Question:  Where can I put my fireplace? 
Answer:  You can put your fireplace in just about any indoor area as long as it is clean and dry. Whether you want to add ambiance to your living room, family room, bedroom, kitchen, foyer or dining room, as long as there's an outlet, there's no problem! Dimplex fireplaces are perfect for single family homes, condominiums, apartments, mobile homes or cottages.
