Thermostat FAQs
Selecting the Right Thermostat:
Which thermostats are available?
The three main types of thermostat available are manual thermostats, programmable thermostats, and smart home thermostats.
Is a smart thermostat worth the money?
We certainly think so. Smart thermostats utilise a range of clever features that can save the average household around 8% on heating and cooling bills.
Which thermostat works with Alexa?
Almost every smart thermostat we sell is compatible with the Amazon Alexa voice assistant. Despite this, always check compatibility with the thermostat manufacturer before buying.
Which thermostat works with Google Assistant?
Whilst most smart thermostats work well with Google Assistant, Google Nest thermostats are fully integrated and gain advanced functionality when paired with other Google Assistant devices, such as the Google Nest Hub.
Thermostat Usage FAQs
Why is my thermostat not working?
If a thermostat isn’t turning on or the display is dark, try replacing the batteries first. If your thermostat doesn’t use batteries, check for a tripped breaker or a blown fuse in the electrics panel. If you’re still having trouble, consult your thermostat manufacturer or call a professional.
What’s the ideal thermostat temperature?
The energy saving trust recommends a thermostat temperature of between 18 and 20 degrees celsius during winter months.
What happens to a smart thermostat when the WiFi goes down?
Smart thermostats are not completely dependent on WiFi, and will continue to function even without internet connection.
You will not be able to control the thermostat through your phone or smart hub without WiFi, but you can still change the temperature through the device itself.
Do smart thermostats work with any smartphone?
Smart thermostats work with almost all smartphones that apps can be installed on. This includes iOS and Android devices. If you cannot install the required app for your smart thermostat, try updating your device to the latest firmware version.
How should I clean my thermostat?
Thermostats can be kept clean with a microfibre cloth. Do not use excessive liquid cleaners or sprays.
Thermostat Installation FAQs
What’s a C wire?
A common wire (C wire) is an extra cable that supplies 24V electricity to a thermostat. Most smart thermostats and some programmable thermostats require them to enable certain features.
Are thermostat wires AC or DC?
Thermostat wires are 24V AC.
Where should I install a thermostat?
Thermostat installation guidelines recommend installing thermostats 1.50m above the floor. Thermostats should not be installed in recesses, shelving, behind doors or curtains, directly above heat sources, or in direct sunlight. Most thermostats are situated in the hallway or lounge of a property.
Who Can Install a Thermostat?
In the UK, installing a thermostat on a heating system, particularly a boiler, involves working with electrical wiring and potentially the gas appliance itself. Due to the inherent risks, it’s highly recommended to use a qualified professional.
The most common and safest option for installing a thermostat connected to a gas boiler, is a Gas Safe registered engineer. They are qualified to work on gas appliances and their controls, which is essential for ensuring the installation is done correctly and safely, without compromising the boiler's function.
A qualified electrician is also a suitable choice, as thermostat installation primarily involves electrical work. They’re trained to handle wiring safely and can ensure the new thermostat is correctly connected to your heating system.
Can I Install a Thermostat Myself?
While some sources suggest it can be a DIY job, it is generally not recommended in the UK, especially for a boiler system. The risks include:
- Electric shock: Working with mains voltage electricity is dangerous and can be fatal if not done correctly.
- Damage to the heating system: Incorrect wiring can cause permanent damage to your boiler or heating controls.
- Invalidating your boiler warranty: Many boiler manufacturers require that any work on the system be carried out by a Gas Safe registered engineer to maintain the warranty.
- Safety regulations: UK building regulations and safety standards for electrical and gas work are strict. A professional will ensure the installation is compliant and safe.
So, to ensure safety, compliance, and proper function, always use a Gas Safe registered heating engineer or a qualified electrician for thermostat installation in the UK. Many reputable companies employ professionals with both gas and electrical qualifications, making them a one-stop-shop for these jobs. Always ask to see their ID card or certificate before they begin work.
How to Set up a Thermostat
Setting up a new thermostat is a multi-step process that a professional installer will follow to ensure it functions correctly and safely with your heating system. While the exact steps can vary based on the type of thermostat (e.g. smart vs. traditional) and the heating system, it’s important to get a qualified professional for this job to ensure the new thermostat is a reliable, safe, and an efficient control unit for your home's heating system.
What do I need to install a smart thermostat?
In order to install a smart thermostat, you’ll need:
- A compatible heating system (check with the thermostat manufacturer before buying)
- 2.4GHz WiFi
- A smartphone, tablet, or smart hub
- Most smart thermostats require a C Wire or a nearby power socket
Do you need WiFi to set up a smart thermostat?
If WiFi is not available, or if you’re installing a smart thermostat in a new build, it is still possible to install and set up smart thermostats through the unit itself. Most smart thermostats function like regular programmable thermostats without WiFi.
