3. Why do my Radiators Feel Colder than they did Before I got a Heat Pump?
Air source heat pumps work differently than traditional heating systems. They operate most efficiently at lower flow temperatures, typically around 35-45°C, compared to gas boilers which have a flow temperature of 60-80°C.
This means your radiators will indeed feel cooler to the touch but will still be hot enough to heat your home.
Before you have an ASHP installed, check if your radiators and pipework are designed for lower flow temperatures. If not, you may need to replace or upgrade them to ensure they can provide adequate heat output.
4. Should I Turn my Heat Pump off at Night?
You don't necessarily need to turn your heat pump off at night. In fact, it's often more efficient (and more comfortable) to maintain a consistent temperature, especially as these systems take a longer time to reach the desired temperature when turned back on.
However, you can save energy with the following tips:
Setback temperature: use a setback feature on your thermostat to lower the temperature at night or when you're not at home. Lowering the temperature slightly during these periods can reduce energy consumption while maintaining a comfortable environment.
Energy-efficient programming: invest in a programmable thermostat to automatically adjust the temperature based on your schedule. This ensures that your home is warm when needed and conserves energy when it's not.
5. Should I Turn My Heat Pump off While I'm Away?
When you're away from home for an extended period:
- Use holiday mode: most heat pump thermostats offer a "holiday mode" or "away" setting. Activate this mode to reduce the heat output to a minimum level. It prevents your home from freezing while conserving energy.
- Maintain a minimum temperature: if your thermostat doesn't have a holiday mode, set it to maintain a minimum temperature (e.g., around 10-12°C) to prevent frozen pipes and excessive energy usage.
- Remote control: if you have a smart thermostat, you can control your heat pump remotely, ensuring it's in an energy-saving mode while you're away.
