Smart Thermostats: Real Comfort And Real Cost Savings

Definition of Smart Thermostat

Before looking very closely at the properties of a thermostat, it may be useful to determine exactly what a thermostat is and what is not. A thermostat is a device that automatically regulates temperature or activates a temperature regulating device based on temperature readings. Basically, it is a thermostat (hopefully) that will automatically control heating or cooling in an area to maintain a certain temperature range. A thermometer inside the thermostat triggers the electric switches; this activates or deactivates a heating and/or cooling equipment.

An effective thermostat is a thermostat that helps you save on heating and cooling costs in your home. The best thermostat can set the parameters you want and set on your own without thinking about it yourself. Or at least very little pursuit. Therefore, in reality, the best type of thermostat intelligently regulates your heating and cooling processes, while also regulating your comfort level and even to some degree your budget.

Older thermostats are capable of regulating the temperature of your home well or accurately, even if it is wise. Even the most basic modern thermostats do a better job of controlling the temperature in your home, resulting in better comfort for your wallet. What’s more, energy-saving thermostats can reduce your energy bills by up to 20%, which means that a new thermostat pays for itself quickly.

Now, when you think that an intelligent thermostat has something to offer, even above and beyond the more modern, energy-efficient one, increase your comfort level by one more degree. Smart thermostats will cost more than the start, but they give you convenience and convenient features (temperature control or A / C, anyone’s volume control, anyone?) And very real energy cost reductions.

Thermostats for years

The following is a summary of the five main types of thermostats available in homes today – what they are and what they offer:

  • Mechanical Thermostats – These are the oldest versions of thermostats and are technologically least developed and therefore least costly. They use a bimetallic strip to measure the temperature and, based on these readings, will adjust the heating or cooling accordingly. They are usually found in old houses and apartments.
  • Non-Programmable Thermostats – These thermostats are relatively inexpensive in themselves. They need a person to adjust the temperature settings manually, but some non-programmable thermostats are digital thermostats with digital operation. Unfortunately, this type of thermostat does not help reduce energy costs unless someone is standing and making day and night adjustments.
  • Programmable Thermostats – This type of thermostat requires you to preset or program your heating and cooling preferences. The thermostat then adjusts the temperature automatically according to these preferences. This programmability frees you from various areas and ways: (1) time, because once you have programmed the thermostat, you no longer have to worry about automatic adjustment, (2) no need for comfort and (3) no need for money. prevents you from heating or cooling.
  • Wireless Thermostats – The cost of these thermostats begins to increase because their technological capacity and requirements are somewhat more complex than previous thermostats. Wireless thermostats allow you to remotely adjust the temperature of your home; this is particularly useful and useful when you are away from home or if you have pets or other individuals who may need a certain temperature in your home (for example, babies, disabled or disabled individuals). or the elderly). Wireless thermostats give you a significant freedom in controlling your home’s temperature, as well as the opportunity to truly reduce energy costs.
  • Smart Thermostats– This type of thermostat is relatively new in the world of thermostat and comes with higher price tags, with increasing technological capacities. However, it is easily debated that these prepaid costs are quickly compensated for with energy savings due to intelligent functionality. Basically, an intelligent thermostat will learn what your home’s temperature preferences are during the day and night, and then adjust the temperatures accordingly. There are various things about what a smart thermostat will do for you and what it won’t do for you, depending on the model you choose, but some use motion detection technology to determine if someone is in the room and adjust the temperature to the motion.

How to Choose the Best Thermostat for You

Although smart thermostats are attractive for many reasons, they may or may not be the best option for you and your space. So how do you decide which thermostat to buy? Here are the basic outlines of the important issues and steps you should take:

Identify the current HVAC system.

Before taking any steps to select a good thermostat, you need to know which thermostats will be compatible with your existing heating, ventilation and air conditioning (HVAC) system. You need to know if your HVAC system fits in one of the following categories:

  • Stage 1 – A system where heating and air conditioning units are separated.
  • 2 Stage – Also referred to as Multi-Stage Heat or Cooling, this is a system with both high and low speed heating or cooling units.
  • Direct Line Voltage – This means that your heating and / or cooling system is running on a 110 or 240 DC power supply; This is more common in older homes to provide power to the thermostat.
  • District Heating and Cooling – Also called Zoned HVAC, this is a single HVAC system controlled by individual thermostats in different areas.

Determine which equipment the thermostat should control.

On the surface this may seem very simple (doesn’t the thermostat just control the heater and the air conditioner?), It may or may not be very simple. For example, some thermostats are designed for furnace control only, while others will work most effectively in controlling both the furnace and air conditioning, a heat pump, or other equipment. Don’t worry – the thermostat manufacturer will clearly identify compatible HVAC systems.

Determine if you need Line Voltage or Low Voltage.

These are two primary types of thermostats and their differences are important. Line voltage thermostats are specifically designed for single heating systems. These include heating systems such as basic card heaters and radiator valves. Low voltage thermostats are often used in central heating and cooling systems using gas, oil or electricity. These are usually more efficient and accurate thermostats with programmable options.

Check C-wire compatibility.

C cable or general cable is an extra wire that provides power to activate extra smart thermostat features such as touch screen. The thermostat you are interested in may or may not require a C wire and may or may not be present in your existing system. If you’re not sure about any of these, you may want to consider calling the home of one of the professionals to check your current system and the new thermostat you want to install.
