What to check before placing an order — written by BestDealz sourcing analysts.

Choose smart thermostats wisely to ensure optimal performance and compatibility for your home.

Check Voltage Compatibility — Ensure the thermostat supports 220V for standard South African homes to avoid electrical issues.
Consider Wi-Fi Connectivity — Verify that the thermostat connects to your home Wi-Fi for remote access and app functionality.
Look for Energy Efficiency Ratings — Select models with high energy efficiency ratings to save on utility bills over time.
Review Warranty and Support — Check the warranty period and customer support options to ensure reliability and assistance when needed.
Choose the Right Sourcing Class — Decide between Class A for quick local delivery or Class B for cost-effective factory direct options.

What is the difference between Class A and Class B sourcing?

Class A offers local stock with faster delivery, while Class B ships directly from factories, including customs and VAT.

Do smart thermostats require professional installation?

Some models can be self-installed, but professional installation is recommended for optimal setup and integration with existing systems.

Are smart thermostats compatible with all heating systems?

Not all thermostats work with every system; check compatibility with your specific heating or cooling setup before purchasing.
