Buying Guide
BTU per foot and space planning
- Calculate room BTU needs by square footage and ceiling height. Higher ceilings or large windows may require more output per foot.
- Baseboard heaters typically deliver steady radiant and convection heat. Look for models offering a mix of radiant warmth and air movement for even distribution.
Choosing between traditional cast-iron aesthetics and modern convection units
- Cast-iron pedestal components add historic charm and stability; they pair well with older radiators.
- Convection-based baseboards are often slimmer, easier to install along walls, and better for contemporary interiors.
Electrical requirements and installation considerations
- Confirm voltage (120V vs. 240V) and available electrical service in your space.
- Wall-mounted units save floor space, while floor-mounted or low-profile options suit small rooms under windows.
- Ensure proper clearances from furniture and drapes to maximize efficiency and safety.
Space and layout considerations
- Longer baseboards provide more uniform heat along walls; shorter units suit compact rooms.
- Under-window placement enhances heat distribution where cold drafts occur.
