Cup on windowsill and cold weather outside

In our last article we talked about smart heating controls and the convenience of remote, programmable heating for your home. In this one we want to introduce you to weatherstat or weather compensation controls in a little more detail.

Some heating controls, as we have discussed, will learn your habits and adjust the heating accordingly. Some will also use GPS on your phone to detect when you have left the house, to time the heating and water perfectly. What if, on top of all this, your controls knew what the temperature was, not just inside but also outside, and could regulate your heating accordingly? This is what weather compensation controls do.

Weather compensation controls have a sensor on the outside of your house as well as thermostats indoors. This outdoor component transmits data about the temperature outside your home to the heating controls inside. Instead of the boiler firing up or turning off when a house is too cold or too hot, a weather compensating system monitors and maintains correct flow and return temperatures, adjusting the heat output to the radiators.

By detecting changes in the outside temperature, this can reduce unnecessary fluctuations in the boiler’s operation, enabling it to work at its optimum efficiency. This reduces energy consumption and can lead to significant savings for you.

In addition, weather compensation controls provide a more even temperature within the property, preventing it getting too hot or too cold.

Components of a weather compensation control system

Weather compensation controls usually consist of a smart controller and two thermostats with internal and external air sensors. Using the data from the sensor outdoors, the controller calculates the temperature to which it needs to heat the water for the radiators in order to maintain an appropriate temperature indoors. It does this before your home starts feeling either too hot or too cold.

This helps your heating system be more adaptable and avoids a simple on/off cycle that boilers otherwise work on. On a cool night, for example, the outdoor sensors will detect the fall in temperature and send a message to the weather compensation control unit that will then use the outdoor and indoor readings to calculate the temperature to which it needs to heat the flow to the radiators.

Because the weather compensation control is operating in response to actual conditions, it can operate your boiler more efficiently. It can apply maximum heat, for instance, when the outside temperature has dropped dramatically but it can tailor its response. It will use less heat and less fuel when conditions outside are warmer. Again, this helps your boiler operate more efficiency and potentially creates savings for you.

We recommend installing weather compensation controls to increase energy efficiency and provide a more comfortable and even temperature inside the property. They are widely used in mainland Europe and are becoming more popular in the UK.
