Limit overnight heating

As part of your Smart+ subscription, you can choose to 'Limit overnight heating' in the Heating settings section of the Homely app.

This feature is designed to stop your home heating above your next morning’s target temperature overnight, helping maintain a slightly cooler sleeping environment.

However, while this may sound appealing, we don’t generally recommend using ‘Limit overnight heating’, as it can reduce your heat pump’s overall efficiency and increase energy usage.

Why we advise against using it

Heat pumps work most efficiently when they maintain a steady temperature using lower flow temperatures over longer periods.

When overnight heating is limited, your heat pump often has to work harder in the morning to bring your home back up to temperature. This can:

• Use more energy
• Increase heating costs
• Put additional strain on your system

Although you may notice a cooler home overnight, this comfort benefit can lead to higher overall energy consumption.

If you'd still like to limit your overnight heating

If you’d still like to try it, here’s how to turn it on:

1. Open the Homely app
2. Tap the Heating tab
3. Go to Heating Settings
4. Toggle on ‘Limit overnight heating’

Important: To ensure ‘Limit overnight heating’ works as expected, it’s important to leave a clear gap in your overnight heating schedule. This may mean adjusting your existing schedule to avoid overlapping heating periods.

We’ve included an example below to show how this could look in practice.

Final Thought

While ‘Limit overnight heating’ is available, we'd generally suggest sticking to your standard heating schedule to get the best performance from your Homely system.

Avoiding this feature helps your heat pump run more efficiently, can reduce energy costs, and  helps reduce unnecessary strain on the system.
