Cons
- Professional Installation Mandatory: Requires a dedicated 240V circuit and hardwiring by a qualified electrician, adding to upfront cost.
- Substantial Power Draw: Its 10KW consumption demands adequate electrical service; older buildings may require panel upgrades.
- Ceiling-Mount Limitation:The fixed installation lacks portability, making it unsuitable for temporary or multi-location heating needs.
The TEMPWARE heater performs reliably under continuous use, with its adjustable louvers ensuring even heat distribution. The ECO mode stands out by modulating power based on real-time temperature, balancing comfort and efficiency. It is best suited for permanently installed applications in well-insulated workshops or warehouses where consistent, high-capacity heating is critical. Minor drawbacks include the lack of a plug-in cord and the need for sufficient ceiling clearance for optimal airflow.
The value lies in its industrial-grade durability and powerful output that cheaper alternatives cannot match. This unit is ideal for the serious DIY enthusiast or professional requiring dependable primary heat for a spacious workshop year after year.
