All You Want To Know About Ventless Gas Heaters

As the name suggests, a ventless gas heater does not involve a venting system. It works by retaining, re-heating and re-circulating the heated air, present in the room rather than venting it out. These devices usually utilize the oxygen present in the room to be heated, for supporting the combustion process. Thus, a ventless heater does not involve exchanging of air with the outside environment. This unique feature of retaining, re-heating and re-circulating the warm air make these heaters highly fuel efficient.

On the other hand, a conventional heater continuously takes in the oxygen from air outside the room and vents out the smoke produced as a result of the heating process. But this venting also dissipates away the heat produced in the room and thus conventional devices are somewhat less efficient than the ventless devices.

• Since no air is being exchanged with the outside environment, a ventless heater does not consist of pipes, unlike conventional heaters.
  

• In terms of fuel efficiency, ventless heating devices stand at a much better position than conventional devices.
  

• A ventless heating device can be mounted on a wall or kept on a floor surface as a stand-alone unit, but a conventional heater always needs an outdoor wall with proper venting system for installation.
  

• The use of ventless heating devices is still not accepted in many places such as California.
  

• Contrary to the conventional devices, a ventless heating device involves minimal degree of emission and is smoke free.
  

• Conventional heaters are still more preferable in terms of safety as there are no chances of accumulation of harmful gases like carbon monoxide in the room being heated with these devices.

1.Ventless gas heaters are highly fuel efficient (up to 99.9% efficiency) as they work by reusing and re-circulating the heated air without making any contact with the outside air.
2.Such devices are eco-friendly as the fuel used in these types of devices is either propane or natural gas, both of which are considered as clean fuels.
3.Owing to the high efficiency, such heaters cause a substantial reduction in the fuel cost for the user.
4.Since there is a minimal loss of heat to the outside environment, such heaters provide the user with a greater degree of warmth inside the room.
5.Since no electricity is being used to operate these heaters, such heaters work even in power failures.

1. If the room in which the ventless gas heater is placed is not well ventilated, it can lead to damaging effects such as rise in the carbon monoxide levels which can have substantial deteriorating effects on the body. Other possible harmful effects include asphyxiation, which stands for a drop in the level of oxygen.
   

2. Using ventless gas heaters lead to a significant rise in the humidity level in the area being heated that could make your walls and ceilings look soggy.
   

3. The installation of ventless gas heaters involves technicalities and should be carried out strictly according to the instruction booklet. Consult a professional if required.
   

4. Ventless gas heaters usually have high costs of maintenance unlike traditional gas furnaces.
   

5. The service and maintenance usually requires professional assistance, preferably at a service center.
   

6. You may need to take special precautions in regard to where your gas heater is being placed. Because such heaters cannot be used within constricted rooms and places consisting of combustible materials such as garages and high traffic areas.

1. Wall Mounted

   -

   This type is suitable for you if your room consists of large walls, but do not consider it as an option if the surface area of the walls of your room is small. You also need to assure yourself that the unit does not make any contact with combustibles.
   




2. Freestanding Type

   -

   This type is supposed to be kept as a stand-alone unit. The advantage over wall mounted type is that these are more portable than them. The limitation is that they take up a significant floor area and is within the reach of children.
   




3. Display Type

   -

   This type encompasses a wide range of gas heaters with customized designs suiting specific needs of specific users.
   

• Blue Flame Heaters -

  Consist of a ribbon type burner. These are either stand-alone or wall mounted type and works on conduction principle.
  

• Radiant Heaters -

  Consist of ceramic/porcelain plates and works by radiating heat to the nearby objects.
  

• Gas Logs -

  Designed for those of you who would like to stay with the classic look of a fireplace while staying away from the ash clutter produced in a wood log based fireplace. But in terms of efficiency, they are not preferable.
  

• A Vent less Heater Can Also Be Designed To Run Using Electricity.

Using a ventless heater is definitely one of the most preferable options for achieving fuel efficiency, but they are still considered to be unsafe from the medical perspective due to few incidents of carbon monoxide poisoning in the past. Owing to this fact, the use of such devices has been banned in states such as Massachusetts and California.

You need to take special precautions, while using these heaters in constricted rooms, as there are high chances of asphyxiation in such cases. You may also have to consider various safety measures while installing such heaters in places with high presence of combustible materials such as garages.

You should always look for modern safety features while buying a ventless heater. One of the key feature, you need to look for is oxygen depletion sensor (ODC) which puts the device in an off-mode in case the level of oxygen falls below the safety level. Other such features include low pressure controls (LPC), thermocouple and tilt controls.

Unlike conventional heaters, ventless gas heaters demand a proper maintenance at regular periods. However, if you choose to overlook this fact, it would sooner or later result in reduction in the efficiency of your device and may also lead to problems of incomplete combustion in your device. Such negligence on your part would surely cost you more, as it would lead to more serious potential defects in the future.

A heating system apart from heating your room, also aims to create a comfortable climate in your room including the controlling of humidity levels as well as pollution.

• a dehumidifier appliance in your room
  

• and implying the aspiration principle, as per which your room would have less chances of developing humidity if the humid air is thoroughly mixed with the dry air inside the room.

Ventless gas heaters are among the best heating solutions available in the market today, in terms of efficiency and cost effectiveness. All you need is correct installation and proper maintenance of your device. So if you are looking for some space heater, which, is able to heat up your space efficiently and cost-effectively without harming your environment, then a ventless gas heater is what you need.
