How to Choose a Perfect Thermostat for Your Steam System?

Don’t assume that all thermostat is incompatible with the steam system. So, while picking the best thermostats for the steam heat system, you have to be careful. Making a wrong choice means you have to pay extra bucks for your HVAC system.

Below are a few factors that you must keep in mind.

Installation

Most thermostats will not give you a hard time to install it. In fact, without proper electrical knowledge, you can install a thermostat. All you need to do is, read the instruction manual and install the thermostat. Even you will find installation process videos of a few thermostats on YouTube.

But, installation is also challenging in a few expensive and fancier models since they require specialized wiring ad connections. To install this type of thermostat, you may need to hire a professional. You also need to know if the connections require C-wiring or not.

Compatibility

Is your boiler well-matched with the thermostat model that you have selected? To be on the safe side, choose for a thermostat model that contains 2H/2C, since most of the time, they have to work with fuel. Also, learning about the source such as gas or electricity or wood, or oil is similarly essential.

Manual vs. Programmable

First of all, ask yourself, do you need a programmable or manual thermostat?

A programmable thermostat will be a good option if you stay at home on weekends and away for any purpose on weekdays. At this point, a programmable thermostat will allow you to save energy since unnecessary heating of the house will not happen.

Alternative Uses of a Programmable Thermostat

The prime responsibility of a programmable thermostat is to assist you in saving energy. It offers you an energy-efficient home. Apart from that, the programmable thermostat has alternative uses too.

Ensures Comfortable Temperature

Using a programmable thermostat, you will enjoy a consistent temperature at your home for the whole day. A programmable thermostat adjusts the home temperature according to the outside temperature. Also, you can customize the temperature settings as per your preferences. Its efficient performance ensures that you will always have a comfortable temperature in your home.

Controlling the Temperature Remotely

Some programmable thermostats are available with a Wi-Fi option, and you can control these thermostats from anywhere if you have active internet service.

Sometimes you may need to stay in a place for a more extended period than expected, and you can easily control the home temperature using the Wi-Fi feature. Even when you are at work and need to change the temperature for any reason, you can comfortably do so with this feature.

HVAC Warns

It is expected that most of the time, we forget to change the HVAC system filter. Some models are designed so that they are eligible to notify you when it is time to change the HVAC system filter. Some models are also available, which can give you notification of HVAC system servicing or checking.

Customize Zones

Some homes have multiple weather zones, and a programmable thermostat is a great option to ensure these homes’ energy efficiency. You will feel comfortable at any corner of your home with a programmable thermostat.

Where not to place a Thermostat?

Installing a thermostat in the wrong place will create a big difference between comfort and efficiency. You have to install a thermostat in a position where the thermostat can perform effectively. Your HVAC system will not work efficiently if the thermostat installation happens in the wrong place.

Installation Places to be Avoided

You mustn’t install a thermostat in the following locations.

Doors and Windows: Avoid installing your thermostat near your doors and windows. This way, the outside air’s hidden temperature may get measured by your thermostat, instead of measuring the inside temperature of your home. Even when the exterior door is opened, temperature fluctuation will frequently happen, giving you a false reading.

Moreover, if your thermostat comes in contact with direct sunlight, you will land with a high electricity bill in summer.

Outdoor Walls: Similarly, avoid thermostat installation in an outdoor wall. In summer, the exterior wall temperature will be high, and in winter, the temperature will be low. As a result, your HVAC system will run inefficiently, and the electricity bill will be high.

Supply Vents: A thermostat will get confused if it is installed over or below a supply vent. It is because the supply vent’s air will be either warmer or cooler compared to your home’s overall temperature. Your HVAC system will frequently turn on/off because of the frequent fluctuation of the temperature. And finally, you will feel discomfort in your home.

Un-used areas and hallways: Unfortunately, many people install a thermostat in hallways. This is not an ideal place to install a thermostat. Now you might be thinking, what is the problem if I install a thermostat in a hallway? In fact, hallways are narrow and long; airflow is less in this area. Which means the temperature of a hallway is not the average temperature of your whole house. Then a thermostat will work to make the hallway temperature comfortable, not for the entire home.

TV Set’s and Lamps: Thermostat should be placed away from TV sets and lamps; the U.S. Department of Energy gives this recommendation. Both the TV set and lamp discharge a little bit of heat, which can mislead your thermostat. This way, in summer, your air conditioner will work for a long time, and you will get a huge electricity bill.

Bathroom and Kitchen: Generally, steam and heat are high in kitchens. The thermostat will think that the home temperature is the warmest, and in summer, you will get high bills. And in winter, since the kitchen is the warmest, your home temperature will not decrease. Installing a thermostat in the bathroom and kitchen is similar to installing it near the doors and windows. Frequent turning on and off will happen to the thermostat, and thus thermostat’s lifespan will decrease.

So, you have already got ideas of where you mustn’t install a thermostat in your home. Keep in mind that installing it in a place where the temperature is not cold or too hot will give you the best result. And position your thermostat 50” – 60” high from the ground.

In order to get the best result from your thermostat, don’t install it in those locations mentioned above.
