What Temperature Should I Set My Radiator To?

Setting your radiator temperature and smart heating system to the right level can be challenging. Not only can recommendations vary from room-to-room, but advice can also be subjective to personal comfort preferences.

It’s important because setting temperatures too low can mean a chilly home and the need to frequently boost the heating, reducing efficiency. But setting radiator temperatures too high means higher energy costs and uncomfortably warm rooms. So, is there a way to achieve balance with Wiser?


How to get the best radiator temperature control

Typically, the common rule for radiator temperature control is to aim to have each room somewhere between 18C (64F) and 21C (70F). In most homes, these central heating settings should be comfortable, and for others, only slight adjustments would normally need to be made to achieve a preferable temperature.

With Smart TRVs, finding the right setting for your radiator and adjusting temperature levels is straightforward. Using the Wiser App, you can change settings for each smart radiator thermostat remotely, and you can set up Multi-Zone Heating Schedules. This means that each room’s radiator can be set to the ideal temperature with ease and could Save up to 18% Energy Usage.

Room-by-room control

Multi-zone smart TRVs are the easiest way to set your heating temperatures room-by-room, with schedule automation and app control, whilst traditional radiators only offer manual control to achieve this. As you may imagine, recommended radiator temperature settings can vary for different parts of your home.


Living Room

One of the most popular areas of any home, many people like their living room a bit warmer, with average room temperatures ranging from 19C (66F) to 21C (70F). Some people even prefer to set this slightly higher, which is why we’d suggest checking out our Smart Radiator Thermostat Efficiency Tips to ensure you don’t waste energy in this room.



Meanwhile, bedroom radiator temperatures are best set a bit cooler to help you get a good night’s sleep, normally around 18C (64F). This can, however, drop as low as 15C (59F) depending on sleeping preferences. Precision is often key with heating controls when it comes to the bedroom, which is one of the ways Smart TRVs Prove Their Worth.



It’s recommended that for babies and young family members, you keep their rooms slightly warmer than most bedrooms, with The Lullaby Trust recommending no less than 16C (61F), but no more than 20C (60F) to keep infants safe from overheating. According to the NHS, a temperature of around 18C (64F) is ideal for young children’s comfort and safety.

However, if you know in the summer the nursery gets warmer, you can adjust the bedclothes your baby is wearing to suit the current temperature, and smart radiator temperature control display each room temperature for easy monitoring.


Other rooms

Smart radiator thermostats are great for balancing out temperatures throughout your home. But, to maintain energy efficiency, you can set bathrooms to a lower temperature as the heat produced by showers and baths is usually enough to maintain a sufficient temperature for the relatively short time these rooms are used. And, for less frequented rooms such as guest rooms, using Smart Modes to schedule heating only for when they’re being used is a good way to avoid wastage.
