Your Wireless Thermostat Buying Guide

A smart heating system can keep your home toasty with less effort on your part – and with less of a drain on your power bill. Our guide highlights the best tips to choose a wireless thermostat that you will love!

Does Screen Size Matter?

Yes, it matters. You will need to see the temperature and other information that is being displayed on the screen. A thermostat with a big screen usually comes with more detailed information and can be easily viewed, even if you have sight issues.

Backlighting is another important feature because it makes the screen much easier to read in the dark.

The Features Of Your Thermostat

Wireless Thermostat Buying Guide

The best smart thermostats offer a wide array of features. These normally include automatic scheduling and room sensors for temperature, humidity and proximity. There’s also geolocation technology, Auto-Adapt technology and even Heating Boost technology.

Those are just the tip of the iceberg. But it’s important to know what you need from a thermometer and one important feature is compatibility with heaters and boilers (and possibly smart devices if you require remote control).

Another thing is user-friendliness. There are plenty of wireless thermostats that are exceptionally easy to operate and they provide excellent results. Why sit with an overly complicated device?

How is it Mounted?

You can save yourself a lot of frustration and effort by only buying a thermostat that is easy to install. Check for models that can be mounted on any surface, including shelves and walls. These are also normally portable so you can move it to another location and reinstall it without a problem.


Q: How does a wall thermostat work?

A: Thermostats use thermal expansion to control your cooling and heating system. Materials that expand when hot and contract when cold is used to bridge the connection of the electric circuit. The alternation in the size of these materials helps the thermostat regulates temperature. This can be achieved through either using bimetallic strips or gas-filled bellows.

Q: How do wireless thermostats work?

A: Wireless thermostats work by establishing a connection with your internet. This allows wireless access between the thermostat and your smartphone or computer. That way, you can control the thermostat setting from anywhere directly on your smartphone, tablet or PC.

Q: How does a room thermostat work?

A: A house thermostat manages room temperature according to the temperature of the air circulating the home. When the surrounding air is warm, the thermostat signals the heating system to cool down. When the temperature of the surrounding air is cold, it will alert the boiler to fire up, heating the room/house.

Q: How to connect the smart thermostat to the boiler?

A: Mount the receiver inside the boiler and run the wires from the receiver to the mains zone valve. To the transformer, run two more wires from the receiver, then link to the thermostat using the step by step DIY manual guide instructions.

Mount the thermostat to a wall inside and away from heat-producing electronics and windows. Finally, program the thermostat with the desired settings and adjust wirelessly and remotely whenever necessary.

Q: How to use a central heating thermostat?

A: Warm up the house only when you’re going to be in it. In other words, set the schedule to begin at least 30 minutes before you will arrive. A 30-minute early turn off schedule also helps if you want the room to cool down before bed.

Also, focus on heating only the places you use the most frequently. Keep furniture and curtains away from the heating system to allow even circulation. Turn the thermostat and heater off when you leave for a long time. If you are away in winter, activate 30-minute, low-temperature settings to come on twice a day.

Q: How to use central heating controls?

A: Electric storage heater commands are usually of two types; an input and an output button. The input button should be set on low in warmer weather (and high during colder days). The output button should be set low during sunny days and at bedtime.

Gas central heating(C/H) systems have four main parts; the C/H dial, the timer, the radiator valve and the thermostat. The dial can be used to turn the heat off or on. The timer allows you pre-set the period your heating system turns on, without using the dial. Each C/H system has instructions on how to set their timer and the dial. The radiator valves can be turned high or low also, giving more temperature control.

You can use the dial or buttons on the thermostat to choose the best temperature.

Q: How to replace a central heating room thermostat?

A: Before proceeding, make sure the thermostat will fit in the old location and turn off the circuit breaker. Remove the thermostat from its mounted position and then remove the mounting plate from the back of the thermostat. Disconnect the wires from the old thermostat, taking note of their exact locations before connecting these to the same place on the new thermostat.

Replace the mounting plate with that of the new thermostat, making sure the wires are threaded correctly through it. Attach the unit to its place on the base mounting plate by carefully snapping it back. Then, turn on the circuit breaker and test the thermostat settings. Check the wiring and afterwards test again.

If you experience more problems, contact a company technician for help.
