Heating Controls for Low-Carbon Systems

Home / Heating Controls for Low-Carbon Systems

Choosing the best thermostatic control for your air source heat pump (ASHP) is crucial for maximising comfort, efficiency, and cost savings. Here's a guide to help you navigate the options:

Understanding your needs: 

Basic vs. advanced features: Do you want a simple controller with basic temperature settings, or do you desire advanced features like scheduling, weather compensation, and remote access? 
Budget: Thermostats range in price, so set a budget and prioritise features within your limit. 
Compatibility: Ensure the chosen thermostat is compatible with your specific ASHP model and technology. 
Lifestyle: Consider your daily routine and how you utilise heating. Opt for scheduling features if you have a variable routine. 

Types of thermostatic contols: 

There are four main types of thermostats

  1. Programmable: Offer schedule features for different times of day or weekdays. 
  2. Smart thermostats: Connect to Wi-Fi for remote control, weather updates, and integration with smart home systems. 
  3. Modulating thermostats: Adjust heating output gradually for improved comfort and efficiency. 
  4. Wireless thermostats: Offer flexibility in placement and installation. 

Key features to consider: 

We would recommend that you consider the following factors when choosing a thermostat control.

Accuracy: Choose a thermostat with high-temperature accuracy for optimal control. 
Display: Opt for a clear and easy-to-read display, especially for frequent adjustments. 
User interface: Look for a user-friendly interface, especially if you're not tech-savvy. 
Connectivity: Consider integration with smart home systems or voice assistants for added convenience. 
Additional features: Explore options like occupancy sensors, geo-fencing, and humidity control for further optimisation. 

Basic users: Consider user-friendly, programmable thermostats like the EPH CP4 – OpenTherm® Programmable RF Thermostat.
Tech-savvy users: Explore smart thermostats like the Honeywell HR914 Wireless Radiator Controller. The HR91 Radiator Controllers are extremely sophisticated and have the ability to sense when a window is opened and how long the room takes to reach a set parameter. This allows the Evohome controller to understand exactly when to turn the heating on or off to optimise energy efficiency.
Efficiency seekers: Invest in a modulating thermostat like the Tado Smart Thermostat or Daikin Intelligent Thermostat for precise control and improved efficiency. 

Tips for choosing the right thermostatic control: 

Consult your installer: Ask your ASHP installer for recommendations based on your system and needs. 
Read reviews: Check online reviews and user feedback to gauge real-world experiences with different models. 
Compare features and prices: Take your time to compare features and prices across different options before deciding.
