Built in thermostat Vs Non thermostat - What to choose?

When choosing infrared heaters for larger spaces, one of the most common questions we are asked is whether to choose a built-in thermostat heater or a non-thermostat heater controlled by a separate thermostat.

This decision is especially important for applications such as warehouses, churches, large halls, workshops, and even residential spaces such as conservatories and open-plan kitchens.

Both options are efficient and reliable, but they are designed for different layouts, usage patterns, and control preferences. Below, we break down the differences so you can choose the right solution for your space.

Built-In Thermostat vs Non-Thermostat Infrared Heaters

Control and Zoning

Both built-in thermostat heaters and non-thermostat heaters can offer WiFi control. The key difference lies in how that control is applied.

Non-thermostat infrared heaters are typically hardwired to a single external thermostat, such as the Netmostat Smart Thermostat. This allows multiple heaters to be controlled together as one heating zone.

This approach is ideal for large spaces where you want:

  • One consistent temperature across the entire area
  • Centralised on/off control
  • Timers and schedules applied to all heaters at once
  • Reduced risk of heaters being left on accidentally

In contrast, built-in thermostat heaters are controlled individually. Each heater manages its own temperature using its internal sensor and WiFi control.

This makes them better suited to:

  • Smaller rooms or single-heater installations
  • Zoned environments such as workstations
  • Spaces where heaters are not always used at the same time
  • Situations where flexibility is more important than uniformity

Energy Efficiency and Running Costs

Both systems are energy efficient when installed correctly, but efficiency is achieved in different ways.

With non-thermostat heaters connected to a central thermostat, energy efficiency comes from:

  • Preventing overheating across large spaces
  • Ensuring all heaters switch off together
  • Maintaining stable temperatures without manual intervention

This is particularly important in commercial and industrial environments where heating costs can escalate quickly.

With built-in thermostat heaters, efficiency is achieved through selective use. You only run the heaters you need, when you need them. This works well in zoned layouts where occupancy changes throughout the day.

Ease of Use and Day-to-Day Management

Managing multiple heaters individually can become impractical in larger spaces. Built-in thermostat heaters require each unit to be adjusted separately, which increases the chance of heaters being left on unintentionally.

Non-thermostat heaters simplify daily operation by placing all control in one place. Using a single thermostat or mobile app, you can:

  • Switch all heaters on or off remotely
  • Apply schedules across the entire building
  • Adjust temperature instantly
  • Reduce staff error in workplaces

This makes centralised control especially valuable in warehouses, churches, halls, and shared commercial spaces.

Installation and Cost Considerations

Built-in thermostat heaters are often quicker to install. Many models are plug-and-play and do not require additional control wiring. This makes them attractive for smaller projects or retrofit installations.

Non-thermostat heaters are usually cheaper per unit but require hardwiring to a thermostat. This adds installation cost but delivers long-term control benefits for larger systems.

It is technically possible to use non-thermostat heaters without a thermostat, but this removes temperature control and scheduling. For safety, comfort, and efficiency, we always recommend using a thermostat with any infrared heating system.

Which Option Is Right for You?

There is no one-size-fits-all answer. The right choice depends on how your space is used.

  • Choose non-thermostat heaters with a central thermostat if you need uniform heating across large areas and simple, reliable control.
  • Choose built-in thermostat heaters if you want flexible zoning, individual control, and minimal wiring.

Both systems are compatible with smart control, timers, and efficient infrared heating performance when correctly designed.

Conclusion

Built-in thermostat and non-thermostat infrared heaters are both excellent solutions when matched to the right environment.

For large spaces requiring simplicity and uniform heating, a centralised thermostat system is often the best approach. For zoned or smaller areas where flexibility matters, built-in thermostat heaters offer greater control.
