Self Regulating

2 Key Points in Pitch What do we mean by self regulation? How does it work? So what!!

3 What do we mean The heater varies its power output in response to temperature temperature power

4 How does it work Variable resistance product resistance temperature

5 How does it work According to Ohms Law P = V² / R As resistance increases power decreases As temperature increases power decreases

7 So what!! Self-regulating benefits – will not overheat or burn out (reliable) – can be overlapped (ease of installation) – provides heat when and where needed (energy efficient) – rapid start-up (less downtime) – uniform temperatures (energy efficient) – cut-to-length (ease of installation)
