A Beginners Guide About Solar Heating

Solar heating is a type of heating that is provided by collecting energy from sunlight using solar panels or photovoltaic cells or solar PV. These are very popular due to the fact that sunlight is a renewable energy source. While they are popular because they are an environmentally friendly heating choice, many wonder how they work.

The sun’s rays contain photons. These photons interact with silicon in solar panels. When this interaction happens, electrons are released. This creates a direct current or DC. A direct current can be converted into an alternating current or AC. This type of energy can be used to run large household appliances such as a heating system.

Electricity is produced by solar panels during daylight hours when they are able to collect sunlight. This happens even when it is cloudy. If more electricity is produced than is needed, the excess is added into the main electricity grid or it is stored in batteries. This electricity can be used at night when the solar panels do not create electricity.

Overnight when panels are not producing electricity, then power is supplied to the building or home from the main grid. This way power is always being supplied.

Solar panels for heating work better on some homes better than others. Houses with southern exposure are the best for solar panels. Houses in sunny climates or houses that get a lot of sun will get more benefit for solar panels. However, solar panels will work anywhere with sunlight.

Solar panels can provide up to 40 to 100 percent of your electricity needs. These usually produce more in the summer and less in the winter.

The controls on a solar heater are a little different than a typically heat pump or other type of heating system. These controls are a little more complex. In a solar control there are sensors, motors, and switches to help run the system. These controls stop the system from freezing or from creating excessively high heat.

One con of a solar heating system is that installing heating solar panels can be more expensive up front. The upfront cost is offset because over time your heating costs will be lower.

After you have a solar heating system in place, the system has to be maintained in the same way a conventional heating unit is maintained, but with special considerations for the solar aspects of the system. You should check with your installer and dealer for any special type of  heating system maintenance.

How gas furnaces Work?

Home owners depend on their gas furnaces each and every winter to heat their homes. A gas furnace should be efficient as well as reliable, to keep the home as warm as possible each and every day. Furnaces use several electrical components to help improve the workability and efficiency of the unit and most operate the same.


One component of the furnace is the thermostat. Modern units use a digital thermostat which is connected to a thermistor. Once the temperature in the home falls to a certain degree, the thermistor will change and trigger the heating system to switch on. This process also works backwards so the unit will cut off once the maximum temperature is reached.


The heating process takes place in a furnace as part of the combustion chamber. This portion is sealed away and will draw air form the duct work that goes to the outside. It is very important for this portion to be set up correctly so the exhaust gases can be taken outside of the home to avoid health hazards inside the home.

Heat Exchanger

The main return of the unit will pull air inside, which will be taken to the heat exchanger and then warmed and returned to the home to produce the heat in the home. The air will not be returned to the inside of the home until the air reaches the desired temperature. The air will then be returned to the home through a series of duct work.


The blower is a large fan that has enough power to move a large volume of air. The blower will draw the air in and then wait for the air to heat before it will distribute the air throughout the home through the duct work.

Overall, gas furnace heating systems work basically as they did from the first time they were created. However, technology has changed, making is easier for furnaces to be installed, repaired and maintained. The gas furnace option is a great choice to heat the home as it can quickly provide warm air during those cold winter months.

It is important to have a top quality HVAC dealer in your area that can provide you with the best in heating service options. Maintenance will ensure that your unit will continue to work as it should for years to come, providing you with an efficient and proper functioning heating system!
