  4. Budget: Of course, cost is always a factor. While higher-end models like the Cadet 240 might offer more features and better efficiency, they also come with a higher price tag. Balance your heating needs with your budget to find the best option for you.

Remember, the goal is to find a heater that provides the right amount of heat for your space while consuming as little energy as possible. Once you’ve chosen the right heater, it’s time to think about where to place it and the thermostat for optimal performance.

Placement of a Heater and Thermostat

When it comes to heating your space efficiently, the placement of your baseboard heater and thermostat is just as important as the type of heater you choose. Here’s how to determine the best locations for your heater and thermostat.

Heater Placement

Baseboard heaters are designed to heat the air at the coldest part of your room, which is typically along the floor on an exterior wall or under a window. As the heater warms the air, it rises and circulates throughout the room, pushing cooler air back down towards the heater. This process, known as convection, helps distribute heat evenly throughout the space.

To ensure your baseboard heater works effectively, position it on an exterior wall or under a window. Avoid placing furniture or drapes in front of the heater, as these can obstruct the flow of heat and potentially create a fire hazard. Also, ensure there’s at least a foot of clearance between the heater and any items in the room to allow for proper heat circulation.

Thermostat Placement

The thermostat controls the operation of your baseboard heater, turning it on and off based on the room’s temperature. To accurately gauge the room’s average temperature, place the thermostat on an interior wall, away from the heater, windows, and doors. This prevents it from being influenced by drafts, direct sunlight, or the heat from the heater itself, which could cause it to turn the heater off prematurely or keep it running longer than necessary.

While some people choose to place the thermostat directly on the heater, this isn’t typically recommended. The heat from the heater can affect the thermostat’s temperature reading, leading to less accurate temperature control. If you do choose to place the thermostat on the heater, ensure it’s on the opposite end from where the heater’s wiring is connected.
