Benefits of Using the Best Thermostat for Heat Pump with Auxiliary Heat

Benefits of Using the Best Thermostat for Heat Pump with Auxiliary Heat Infographic

When you are going to purchase a piece of the thermostat, definitely at the beginning you will think, what benefit it will give me. The advanced designed thermostat has a lot of benefits that you can deny the importance of using at your home. Let’s find out the benefits of the best thermostat.

Saves energy bills:

The first and foremost benefit of using a thermostat is, you can save your electricity bills if you use it correctly. Using their programmable feature, you can control the temperature, turn on/off of your home appliances. When you are not at home, but unwillingly you have kept your air conditioner on. You can close it off simply by pushing the button of a thermostat. They will automatically adjust your home temperature when you are sleeping.

Their HVAC system is skilled enough to give you a comfortable temperature before you come home from outside or wake up in the morning.

Comfortable scheduling:

You will find 3 types of the programmable thermostat on the shelves of stores. They will provide you with different types of convenient scheduling based on your requirement. Firstly, the 7-day thermostat model is most suitable for those households where a different schedule is maintained every day. Secondly, 5-2 model thermostat is perfect for a setting where there are separate settings in 5 weekdays and 2 weekends. And the last model is 5-1-1, where families have multiple schedules for 5 weekdays and each weekend has a different schedule.

Precise, controlled temperature:

A programmable thermostat will give you an accurate temperature than an old, analog fashioned thermostat. According to a study done by the Air Conditioning Contracts of America stated that an analog thermostat would give you +/-5° variance about the temperature. Whereas, a programmable thermostat will provide maximum +/-1° deviation. Programmable thermostats are more accurate than the analog ones.

Now, maybe you are thinking, this +/-5° is not a matter of headache. But if I say you are unknowingly using more energy and thus you are getting ghost electricity bill. Can you deny it? You can’t, because you don’t know what should be the correct temperature for your home. If you own an analog thermostat, replace it immediately. It will not take much time to return you the profit.

Controlling the motion, light sensors, and humidity:

You will find a thermostat that will adjust the temperature based on the occupancy. These devices will become idle if there is no presence of light or motion in a home. A dehumidifier or humidifier thermostat can keep the humidity level in a comfortable position automatically as per your requirement during summer or winter.

Do you know the range of an ideal humidity level? The range is 30% – 50%. If the humidity level doesn’t remain within this range, it may lead you to several problems like damaging the structure of your home. You may start facing an allergy and asthma problem.

Remote temperature controlling:

A Wi-Fi accessible thermostat will allow you to control it through your smartphone or pc or tablet. Thus, you don’t need to be in front of the thermostat. Whenever you need to control the system, you can complete it efficiently.

The lockable setting of temperature:

Using this benefit, you can take more precise control over your programmable thermostat. Some thermostat comes with lockable settings of temperature that will allow you to lock the temperature level. And thus, someone simply can’t change the temperature unexpectedly. This will let you save your cost too.

Enhance the efficiency of your home:

A thermostat will let your home become more efficient throughout the full season. It means you are efficiently utilizing your resources. You are preserving your systems, and thus your appliances will last longer.

So, today’s advanced thermostats are not only controlling your temperature, but also they are well enough to make your life comfortable and relaxed.

How to Get the Most Benefit from Your Thermostat?

Thermostats units are available with different features. They are temporary, hold, and vacation settings. When you are out of home or on vacation, choose vacation mode. If you are staying at your home without going anywhere, select the temporary method. The hold feature will change the setting, and the thermostat will not come in a workable mode until completing a 24 –hour cycle.

Thermostats that run with batteries, do a periodic check to get rid of any system failure due to less battery.
Choose and select the energy-saving settings at least for 8 hours continuously to get the maximum efficiency.

Thermostat Maintenance Checklist

To get a capable thermostat, you need to do regular maintenance of it. And this maintenance should be your DIY project.

  • Adjusting temperature setting: There will always be a difference between a cooling temperature and a heating temperature. You should set up the temperature without changing it frequently.
  • Keep the outdoor unit always clean: After finishing every season, don’t forget to clean the outdoor area. Because, during every season, debris and other dirty items may accumulate in the outdoor unit. If any debris or dirt is creating an unpleasant environment in the outdoor area, don’t forget to clean it. Also, don’t think about planting anything within 4/5 feet of the outdoor unit.
  • The air filter needs regular cleaning: A clean air filter confirms that your heat pump will work smoothly. Thus, you will get an impressive performance from your thermostat throughout the season. Your heat pump will remain safe from any types of damage. So, periodically cleaning the air filter is mandatory.
  • Give a well-rinse to the condenser: If you find dirt or dust is building up after the winter, summer and spring season, don’t forget to wash it thoroughly. Before giving it a rinse, make sure to turn off the system. Also, confirm; you gave well-rinse using a hosepipe. Also, you shouldn’t use high pressure because due to this, the fan may bend.

You will never regret if you spend much more time on taking regular maintenance of your device. Regular maintenance will confirm the longevity of your devices.
