* Electricity rates vary from place to place. If you know the electric rate charged by your utility, we would be pleased to calculate your hourly cost.

* Many gas fireplaces advertise 70-80% efficiency. This means that 20-30% of the energy supplied to the units is vented outside.

It is important to remember that most fireplaces are selected as an auxiliary source of heat and rarely as the primary heat source in a dwelling.

Symphony in conjunction with your primary heating system
The Symphony Fireplaces produce about 4500 BTU of total heat.* Working in conjunction with the home's primary heating system, the Symphony 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.

Symphony heating an area by itself
The Symphony Fireplace has been sized to suit most applications. The area it will heat depends on the temperature differential that you are trying to maintain between the inside heated area and the outside. Assumming the Symphony is the only heat source available and you have average insulation. (R12 walls/R20 ceiling) then the chart below applies:

Example #1 (Refer to chart)
On a cool evening with an OUTSIDE TEMPERATURE of +50°F/+10°C, the Symphony Fireplace can comfortably maintain a +75°F/+24°C INSIDE TEMPERATURE in a ROOM SIZE up to 700 sqft/64.7sqm. For example, the room could be 20' x 35' or 6.1m x 10.6m.

Example #2 (Refer to chart)
In cooler seasons, with OUTSIDE TEMPERATURES reaching +32°F/0°C, the Symphony Fireplace can warm a 435 sqft/40.4 family room to an INSIDE TEMPERATURE of +72°F/+22°C. For example, the room could be 29' x 15' or 8.8m x 4.6m.

Example #3 (Refer to chart)
On those really cold days when the OUTSIDE TEMPERATURE dips to -4°F/-20°C, the Symphony Fireplace can take the winter blues away by comfortably heating a 242 sqft/22.4 sqm living room to an INSIDE TEMPERATURE of +68°F/+20°C. For example, the room could be 12' x 20' or 3.6m x 6.1m.

* The blower units on many gas units are very powerful (and noisy) in order to disperse higher heat production.

Whether the Symphony Fireplace is being installed into one of the many attractive "no-tools-required" mantels or into an existing fireplace opening, installation is fast and easy!

* Many other fireplaces have very limited or no flame adjustments at all.

* In many gas unites, 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 warmer climates they many not come on at all unless the thermostat is set higher than the room temperature.

* Most gas fireplaces transmit heat by radiation from the heated glass panel which provides high close range heat, and by convection when the fan cycles on and off, as controlled by the thermostat.

* Most other fireplaces require ongoing costly maintenance which must be performed by qualified service technicians.
