How Does the Pleasant Hearth Fireplace Work?


Quick Answer

The Pleasant Heart fireplace works by heating air using an electric heating coil and circulating the heated air throughout a space using a blower fan. The Pleasant Hearth fireplace actually works similarly to some space heaters, but it is much larger and has a higher heating capacity. A light bulb and a special plastic film produce the flickering flame effect inside the fireplace.

Full Answer

The Pleasant Hearth fireplace has two key components: the heating element and the blower. The heating element is a material that resists electrical current. When electricity passes through the heating element, the energy that gets consumed by resistance gets released from the element as heat.

The blower is a small fan inside the fireplace. When the heating element heats air, the blower removes that air from the fireplace, while at the same time drawing cold air into the heating chamber. The blower is essential for heating a large area, as without the blower, the fireplace would only effectively heat a small area around itself.

The flickering flame effect produced by the Pleasant Hearth fireplace results from a regular light bulb and a moving diffraction grating. The diffraction grating is a piece of plastic film that scatters light at particular wavelengths. As the diffraction gradient moves, it scatters light from the light bulb randomly, producing an effect that simulates natural flames.
