Furnace Repair Toronto Services

 Forced Air Furnaces

Furnace Repair TorontoYour house can be heated with the most usual, economical, and dependable source. The forced air system is the best variant among others for adding indoor air quality options. For Services offers furnace repair Toronto services: all types of filtration, air cleaners, humidifiers, UV system, HRV, and other ventilation systems.

If your house has a radiant heating and you would like to add an air conditioning there, there is a need of installation of a forced air delivery system to distribute your air conditioning. The most usual kind of forced air heating system uses natural gas as a fuel. Other options of fuel can be oil, propane, electricity, wood, and even coal. But they are less commonly used in such systems.

Benefits:

  • Only this kind of system can be used for central air conditioning.
  • You can get the addition functions of indoor air quality, for example humidifiers, better filtration of air and ultra-violet lights.
  • There may be a dehumidification of air.
  • It requires less cost for installation and operating processes.
  • A furnace can attain higher efficiencies than other heating options.

Drawbacks:

  • There is a need of ductwork for distribution, which requires duct chases in walls and ceilings.
  • It is not quiet during the working processes.
  • Airflow can bring up allergic agents and deliver them into the air you breathe.
  • Forced air requires filtration. You must replace filters regularly.

But, by far, the typical gas furnace is the traditional forced air furnace system, which most of people know and use.

Traditional System, Which Fires With Gas

A forced air furnace pulls return air from the living place through ductwork and delivers the cold air to the furnace.

Thermostat makes a call for heating to the furnace. The burners come on, heating up a heat exchanger inside the device. Once theheat exchanger reaches a preset level of temperature, here comes on the blower or circulation fan. The cold return air goes past and around the combustion chamber picking up the warmth, and then the now hot air is delivered through ductwork back to the living place. As long as the furnace receives the call for heat, this cycle will continue.

The design of most furnaces, which work on gas, are done to provide heated air at approximately 54°C. Once the heated air gets out from the ductwork, through the registers, into the living place, it quickly mixes with the existing colder air in the area. This operation continues until the air is mixed well in the apartment, and the set-point of the thermostat has been reached; The t-stat has been satisfied. The furnace will then stop its operation process until the level of temperatures in the living space cool to a point when the t-stat calls for heat, once again.

You can find traditional forced air furnaces, which work on gas, anywhere from 40,000 BTUs to 165,000 BTUs for residential units. The blowers are also rated from 2-ton to 5-ton units. The capacity of the blower is especially critical if the furnace pulls double-duty and provides distribution of air for a central air conditioner.

In the old days, not so long ago, forced air furnaces were equipped with a standing pilot. This pilot was a small flame, which ignited the burners on a call for warmth. The pilot could consume 2,000 btu/hr.

Furnaces, which you can buy today, do not use a standing pilot and have been replaced with electronic ignition, spark igniters, or hot surface igniters. That is why nowadays process of furnace repair Toronto is much faster and easier.

AFUE Definition

The efficiency of furnace was raised due to the change away from the standing pilot. ASHRAE admits that 16% savings of energy once a natural draft furnace with a standing pilot has been replaced with a fan-assisted furnace with electronic ignition.

At one time, the efficiency of furnaces could be 55% AFUE. The minimum efficiency, which is allowable, tin our days is 80% AFUE.

Annual Fuel Usage Estimate (AFUE) means the efficiency.

Professional Furnace Installation Company80% AFUE means that 80% of the fuel burned by the unit is providing warmth for the house. The other 20% is going up the flue and heating the outside. By installing a furnace, which is rated at 94% AFUE, now 94% of money you pay for the heating is actually heating your house, and only 6% is lost to the outside.

Natural draft and fan-assisted furnaces are typically in the 80% AFUE range. These devices are open, or atmospheric, combustion units. A natural draft furnace relies upon heat rise and buoyancy to pull combustion air into the combustion chamber and force exhaust gases out the flue. A fan-assisted furnace utilizes a small fan, or inducer to pull combustion air in, and force combustion products through the furnace.

Efficiency Furnaces Of High Efficiency

Processes of venting and combustion change a little if we reach 90% AFUE or better. These furnaces are direct-vent units. That means that both intake (combustion) and exhaust air are piped directly to the outside. Indoor combustion air is not used. The combustion chambers are sealed to make the control of the process of combustion better.

The second name of such forced air furnaces is condensing furnaces. They recover waste warmth from the exhaust gases, which would normally be pushed out into the atmosphere. Such models of devices are designed with larger surface of heat exchanger, which pushes warmth from water vapor being produced during the process of combustion. Condensate, which must be disposed, is produced by these devices. It condensate water is acidic. For condensate disposal, you can use cast iron and plastic drains, but galvanized drains are not accepted.
