As the days get shorter and colder, the question of when to switch the heating on begins to arise.

There is no one answer to suit us all, but our heating pros advise that instead of turning to the calendar, you should tune into certain conditions in your home instead.

Here's how to work out exactly when to switch on your home heating types this fall to keep you comfortable and balance energy use.

When to switch heating on

The best time to start taking steps to keep a home warm all day will depend on several factors, including, but not limited to, the weather, your home and attic insulation, your daily activities, your health and personal preferences.

As a result, there is no one set date to switch heating on, says Reuben Saltzman, owner and CEO of Structure Tech Home Inspections. Instead, you should check the conditions in your home.

He explains, 'Once your indoor temps are consistently dipping below 65°Fahrenheit, or you're just plain uncomfortable, it’s time to fire up your heating system. The temperature range of 65-68°F is a sweet spot for comfort, moisture control, and energy use if you are looking to make heating more efficient.'

A small digital home thermometer, from Walmart, can help you keep tabs on your indoor temperature throughout the year.

Reuben continues, 'Another sign you want to look out for is morning condensation on windows or exterior walls.

'Cold interior surfaces drive condensation and mold, not just the outdoor temperature, so keeping the inside above that point matters. But when it gets very cold outside, you'll probably need to bump up the temperature on your thermostat to stay warm.'

Turning your heating on when you first notice these signs, rather than putting it off, not only keeps you healthy but also protects your home from damp. Plus, it is quicker and easier to warm up a home that is not absolutely frigid.
