How to compare for baseboard vs. wall heaters
- Baseboard radiators: Prioritize models that explicitly support 120V–240V line voltage and provide clear 4-wire or compatible installation.
- Wall heaters: Check whether the thermostat supports the specific wall-embedded control needs and whether multitier scheduling aligns with your daily routines.
Energy savings and usage
- Look for certificates like ENERGY STAR or stated savings percentages, and verify with your utility’s rebate programs where available.
- Consider how schedules align with your weekly patterns to maximize savings during workdays and nights.
Installation tips
- Turn off power at the breaker before wiring. Abide by local electrical codes and, if unsure, consult a licensed electrician.
- Use the provided installation guides and videos from the manufacturer to ensure correct wiring and mounting.
