Today, most gas fires built or "manufactured" in factories are designed as "direct exhaust" fires. These energy-efficient ventilation systems have replaced older designs and are actually the main style of fireplaces used in houses built nearly 20 BC. 30 years. These fireplaces also offer the ideal opportunity to refurbish or extend space utilization. Do you believe your house needs a directly ventilated fireplace? 

Fully enclosed chimneys that can inhale new air and eliminate combustion byproducts from the building are direct ventilation chimneys. The two primary types of chimneys are direct ventilation: coaxial and hills. The first type, coaxial, consists of tubes in a tube, and the outside is used as an inlet and an outlet through the inner tube. The second type of chimney with direct exhaust, collinear, consists of two longitudinal pipes, one of which is used exclusively as a suction pipe and the other as a dedicated exhaust pipe.

There are various advantages to both fundamental forms of direct ventilation. Each method can avoid problems such as hypoxia and bad desires. In addition, these fireplaces do a good job with high requirements for energy efficiency.

Main characteristics of a direct ventilation chimney

The direct-ventilated chimney has a "sealed" inlet and outlet. This equipment pulls air out of the home, releases it to the exterior, and radiates heat within for effective design. Unlike traditional or B-shaped chimneys, the performance of direct ventilation chimneys-the chimney will not have much influence on the airflow and air pressure in the house.

Ventilation considerations

Metal straight vents can be rigid or flexible, depending on installation requirements and the manufacturer's instructions. These ventilation slots can lead to the ceiling through the exterior wall, or they can be guided by electrical ventilation slots to avoid obstacles or excessive distance. When installing direct ventilation, a stone fireplace is not required, but the distance from the fuel must be maintained according to the manufacturer's instructions.

Power considerations

Most gas fireplace runs on gas and needs no electricity for basic operations, directly ventilated. A simple and dependable millivolt valve system combines the continuous modeling light to provide a secure design. headlight or electronic ignition system. In addition, most newer equipment has a flashing warning light, which uses electricity to light the warning light and turn on the equipment; then the pilot will go out after use to save fuel and extinguish any continuous flames.

How to set up a direct drawer?

The installation of directly ventilated fireplaces must be carried out by trained professionals to ensure safe operation. Always examine information about direct ventilation adjustments from the equipment manufacturer. Note that a special ventilation system must be employed to ensure the correct installation of every fireplace. This operation is made easier by a certificated installer, however, the documentation for each chimney gives specifications and ventilation tables. Although the direct ventilation system is simple and straightforward, we know that each Installation has its own parameters that may generate unique installation challenges. This is another reason to negotiate with us and certified installers.

Are fireplaces direct wind power efficient?

Directly ventilated chimneys are energy efficient for a variety of reasons, not least because directly ventilated chimneys do not draw heat/air from the room, but are a self-sufficient heating device. Therefore, the working efficiency of some of them is as high as 70%. Those chimneys also work better than standard or 'decorative' vented gas blocks, which lose the bulk of the heat through the chimney.

How much does the fireplace cost to run?

Fireplaces are usually measured in British Thermal Units per hour. The usage of natural gas normally amounts to 100 000 BTU in thermal units. With this in mind, many direct exhaust chimneys have a nominal capacity of 20,000 BTU/h to 30,000 BTU/h, which is approximately 1/5 to 1/3 of the heat output of natural gas or a gallon of propane.

As of November 2019, the U.S. government estimates typical hot gas costs of around $1.06, which results in 20 to 35 cents per hour of the cost of natural gas. Approximately 91,000 BTU per gallon. According to US government data, by 2019, the price of volumetric LP will be between US$2.00 and US$2.50 per gallon, which means that the price of chimney bars will be between 40 and 83 cents per gallon.
