What to Look for Before Buying Thermostat?

What to Look for Before Buying Thermostat

Your ideal thermostat may depend on factors beyond the price, design, or explicit features. The buying guide will help you identify the factors.

Electronic or Hydronic?

As far as radiant floor heating is concerned, there can be two types, which are electric and hydronic. When purchasing a thermostat for floor heating, make sure the thermostat is designed to function in accordance with the radiant heater’s type.

Is Going ‘Smart’ Mandatory?

Definitely not! In the age of smartphones and gadgets, smart home devices seem desirable. However, it all depends on your comfort.

If you are not comfortable navigating smartphone apps or smart home systems, you would be better off saving some money and purchasing the non-smart versions of the device.

Smart thermostats, however, are the best option for places where the temperature fluctuates heavily.

Keeping in sync with the weather, these thermostats can help save hundreds of annual utility bills! If the weather in your area is relatively stable, you will suffice with a manual thermostat.


Not all heating systems or wiring configurations are compatible with all thermostats available on the market. It is best to get the compatibility checked by a professional before you shell out the big bucks.

Energy Usage

Some thermostats give you usage reports which cover your energy consumption as well as costs incurred. If you are interested in monitoring your usage, search for these models, which mostly belong in the ‘smart’ category.

Other Features

Some thermostats offer tempting features like built-in Alexa or Spotify or traffic alerts. While these thermostats are marketed in a way that makes them seem indispensable, focus on the benefits you demand from your device to avoid paying for features that will go unused in your home.

Frequently Asked Questions

What is a C-wire? How can I identify the C-wire for DIY installation?

Common, or ‘C’ wires, supply 24V electricity in North American standards. They are required for Wi-Fi-enabled thermostats, and this particular type requires extra power to run smoothly.

If your C-wire is not in use already by other devices, it may be tucked away neatly inside the wall. Look behind your thermostat, furnace, or so on to find the wire.

In most cases, the wire will be black or blue in color – however, that is not true for all common wires.

Will radiant heating ruin hardwood floors?

Radiant floor heaters only emit temperatures that are higher than that of the room itself. The temperature being emitted does not fluctuate widely;

hence your floors will not contract or expand beyond its capability. Rest assured that your hardwood floors will remain as they are!

Why is radiant heating the best option?

This is where grade 7 physics kicks in – further down the source of heat is, more even the heating will be.

Thus, when heat radiates from the floor, it warms up all the furniture and the air itself evenly, resulting in a comfortable ambiance.

Radiant floor heating provides superior comfort but does not demand regular, tedious maintenance. It also operates more efficiently relative to other heating options.

How much does it cost to have radiant floor heating installed?

It can cost about $7 to $12 dollars per square foot on average.

Does it make sense to have a separate cooling and heating system?

That is probably the most efficient way to go on about it. Separate systems don’t put undue pressure on a single system; that way, both systems serve for a longer time.

You can also pick the best air conditioner as well as the best heater without compromising on features.

Final Words

Radiant floor heating is one of the most popular options for overall home heating. And your investment in such a system only deserves the best thermostat for radiant floor heating for efficient usage and optimum results.

We hope the guide has answered most of your questions, and you’re well on your way to make your home warm and cozy.
