How Weather Compensation Can Make Your Home More Energy Efficient

Published On February 4, 2019 | By Mary Carlisle | Home improvement

The UK has seen a massive growth in energy efficient homes in the past few years. Renewable energy such as rooftop solar panels, wind turbines, solar water heating and solar air conditioning have made a big impact to the environment as well as reducing electricity use and costs. In this article we are going to focus on weather compensation and how it can make your home more energy efficient.

What is Weather Compensation?

Weather Compensation is a form of communication between an external temperature sensor and the boiler. It works by registering the temperature outside, with the help of the sensor, and adjusting the temperature inside accordingly. The controller alters the heat supply around the house, to all the radiators, keeping the temperature constant inside throughout the day.

How Does it Work?

This type of central heating works by keeping the house typically between 18 and 21 degrees, no matter the weather. The outdoor sensor picks up on any drops in temperature and sends a signal to the boiler. The boiler operates at a lower or higher temperature, adjusting the radiators accordingly to maintain the room temperature and to compensate for heat loss.

Is it Cost Effective?

According to Phil from Enhanced Energy Solutions “This is a question people ask frequently. Transitioning from any type of central heating to a weather compensation method is very cost effective and has shown to save between 10% and 30% on the overall gas bills.”

Is Weather Compensation Suitable for Older Buildings?

Older buildings tend to have a more rapid heat loss, but unless the temperature gets exceptionally low on the outside, weather compensation will work just as well in a new building or an older one.

Is it Difficult to Set Up?

The outside sensor is attached to the wall using one or two screws. A low-voltage wire is then run from the sensor to the boiler and clipped into two ports. The boiler then can detect the changes in temperature and automatically adjusts the weather compensation mode.

What are the Key Advantages?

  • Lower gas bills
  • A comfortable home
  • No need to constantly adjust the temperature manually
  • Cooler radiators
  • Constant hot water
  • A quieter boiler


The need for weather compensation systems depends highly on your circumstances. Homes with inhabitants that stay in most of the day, or with infants and elderly people, benefit more from it than homes that are left empty for long periods of time. The larger the consumption, the bigger the financial return will be.
