With all that being said, if there are no extreme factors involved, the average run time for a furnace is 10-15 minutes per cycle. Your furnace may need to run two to three times an hour to maintain your desired temperature if your home has average insulation.
Why does my emergency heat keep coming on?
Why did my emergency heat setting kick on? Your emergency heat setting automatically turns on when outside temperatures drop below a certain temperature, usually 30 degrees Fahrenheit. If you need to manually turn it on, you should call an HVAC professional to get your heat pump fixed.

What should the fit value be on a rickardair electric heater?
The Fit column indicates the maximum fitted heater size recommended, the Adjust value indicates the maximum heater setting recommended to achieve a 15°C (VAV) or 10°C (CAV) heat rise and the Set column is the MLM Heater Output % value required to achieve a 15°C (VAV) or 10°C (CAV) heat rise.
How does phase angle firing affect heater life?
It is the most precise method of control. Phase angle firing can increase heater life up to seven times depending on heater type. Phase angle firing also allows options such as soft start, voltage limit and current limit. These options are not available with any other means of control. 2
What happens when you use a relay to turn on a heater?
Remember, a heating element is made of wire in most cases. If you use a mechanical relay to turn on your heater, it will cycle on or off within 30 seconds or longer. The heater will expand and contract, getting more and more brittle each time. This is called thermal shock. Temperature overshoot may also occur.
How does a TRIAC switching set work on an electric heater?
This is done by means of a triac switching set (current valve) which varies the heater output capacity by cycling the power supply to the heater on and off – Pulse Width Modulation (PWM). This switching takes place over a cycle of approximately 2 seconds and always occurs at zero voltage to avoid radio frequency interference and voltage spikes.
Why does my spa heater run for 15 seconds?
