Factors To Consider While Choosing The Thermostat

Whether you have a gas or electric heater, with a thermostat, you maximize its efficiency. But you can’t just go to the market and purchase any thermostat heater, rather you need to consider multiple factors for choosing the right one. 

Heating System Compatibility

Your choice of thermostat mainly depends on its compatibility with the heating system. The heating system and thermostat must be compatible to obtain temperature comfort and savings on your bills. Not all thermostat heaters support all types of heating systems. Choice also varies if you have a one-stage or two-stage heating system. 

You may require different thermostats if you have a separate heating and cooling system or zone control. It is mainly a concern when opting for a smart thermostat with HVAC.

Energy Efficiency Features

One of the goals for investing in a thermostat heater is to save on energy and energy bills. The modern thermostat comes with energy-efficiency features, including remote control, WiFi connection and remote access using a smartphone, along with automatic time and temperature control features. Some thermostats also have additional energy efficiency features such as power cycle, filter replacement reminders, and using data to set the temperature and vacation scheduling properties automatically. 

You must also check Government’s energy smart tips to save on energy bills. 

Budget Considerations

Your choice of a thermostat is highly influenced by how much you are willing to spend on buying one. A manual thermostat costs around $ 80, while the smart and most modern ones cost up to $400. Installation charges are charged separately, further increasing the price. 

Due to budget constraints, you may want to give up on quality features that save energy and money in the long run. A thermostat can help save up to 10* on energy bills. In short, one should select a thermostat heater with excellent features within the budget and offering energy efficiency.

User Friendliness And Control Options

It is important that a thermostat with the most advanced features has great control options and is easy to use. Users can control thermostat heaters using remote controls on their smartphones or computer. You can also set up automatic settings using temperature sensors to turn on and off the heating system automatically. 

Melbourne’s Climate Considerations

The average annual Melbourne temperature is 14.8 °C. The city experiences cold days when the temperature falls to freezing point in winter and some hottest days too when the temperature reaches 40  °C. or above. The wide range of temperatures makes it mandatory to control indoor temperature. While choosing the thermostat, you must select the one that allows setting temperature to a broader range so the internal temperature is not too cold or too hot for the family members.

Additional Features and Compatibility

You may wish to get a lot of features with your new thermostat, but here is a catch. A complex thermostat is prone to more errors and malfunction. But at the same time, they are beneficial for temperature control and energy saving. You must choose a modern thermostat with advanced features that is compatible with the existing heating and cooling system and other smart devices at home. 

Always select thermostat heaters with good features and from reputed brands that offer warranty and excellent after-purchase services.

Installation And Professional Assistance

Although many thermostats come with a DIY instruction label allowing them to install a thermostat on their own, it is a challenging job, and you may require professional help.
