Finding the Sweet Spot: The Best Heat Pump Temperatures for Year-Round Comfort and Efficiency

Getting the most out of your Carrier Toshiba heat pump system isn’t just about staying warm in winter or cool in summer — it’s also about setting the right heat pump temperature for comfort, health, and energy savings.

So, what is the best temperature to set your heat pump to? Here’s a simple guide to help you create the ideal environment for every room and every time of year.

Winter Comfort Settings

Recommended temperature: 20–22°C during the day

During the colder months, it’s tempting to turn the heat right up — but setting your heat mode to around 20 to 22 degrees Celsius is usually enough to keep your
home cosy without overworking your system or increasing your power bill.

For sleeping:
Keep it a little cooler overnight – around 18–20°C is ideal. This helps your body stay in a deeper sleep, while still keeping the chill away.

For young children or the elderly:
Aim for around 21–22°C to ensure extra comfort and avoid the cold.This is especially important in homes with vulnerable family members, where maintaining a stable indoor temperature can support health and wellbeing.

Helpful Tip:
Using the timer function or WIFI App function can help you warm the home just before you wake up or return home — without leaving the heat pump running continuously, which improves energy efficiency.

Summer Cooling Settings

Recommended temperature: 19-21°C during the day

In summer, it’s all about staying cool without freezing the room. Setting your heat pump cooling mode to 19-21  degrees Celsius is the sweet spot — it’ll keep the space comfortable while also using less energy.

Avoid setting it too low (like 16–18°C), as this can cause your air conditioning unit to work harder, leading to higher power bills and unnecessary wear.

For sleeping:
A temperature around 19°C is usually comfortable for most people at night in summer. If your room tends to get stuffy, using the "dry" or "fan" mode can help reduce humidity levels and keep things fresh.

Study and Learning Environments

If you or your kids are working or studying from home, the temperature of your space can actually impact focus and productivity.

Recommended temperature: 20–22°C
This is considered the best range to help maintain focus without feeling
sluggish or distracted. Consistent indoor temperatures can help create the right environment for learning and work.

Efficiency Tips for Every Season

• Use your heat pump’s auto mode if you’re unsure — it will help maintain a consistent temperature with minimal effort.
• Close doors and curtains to keep heat in during winter and block out sunlight in summer.
• Keep your heat pump filters clean — a dirty filter makes your heat pump work harder and less efficiently.

Regular heat pump servicing helps keep everything running smoothly and extends the life of your system.

By setting your Carrier Toshiba heat pump to the right temperature for the season and your space, you’ll enjoy year-round comfort — while keeping your energy consumption and power bills in check.
