Is Hydronic Heating Energy Efficient?
As consumers become more eco-conscious there is a growing demand for product options with a lower environmental impact. One of the main home comforts that significantly contributes to our carbon footprint is home heating. However, if you’re looking for a solution that’s kinder to the environment, hydronic heating is the perfect option.
Hydronic heating functions by using water to heat the room. The process begins in the boiler; then circulates hot water around the home through a pipe distribution system, with heat emitted from radiators and underfloor heating.
So, what makes hydronic heating so efficient?
Hydronic systems emit heat through thermal radiation underfoot or close to floor level, providing warmth while maintaining lower ambient room temperatures. The system cleverly manages by transferring heat without the need for forced air circulation, thereby increasing energy efficiency and reducing heat loss. Win-win.
Heat conduction through water
Water is an excellent conductor of heat, this is maximised by insulated circulating pipes to ensure there is minimum heat loss. When the water cools, it is effectively recycled back into the boiler to be reheated.
With zoning capabilities, you can turn off less used radiators and set individual temperatures for each room to save energy and costs. When the room reaches the set temperature, the heating turns off and only restarts when the temperature drops, ensuring you maintain a comfortable heat at all times.
The Nest Learning Thermostat is a great example of a device that maximises energy performance. It learns your schedule within a week of use and then self-programs to ensure your home is heated how you like it, when you like it.
Traditional gas-fueled boilers produce heat by burning natural gas, resulting in carbon dioxide and water vapor production. These end up escaping through the boiler’s flue, taking a huge chunk (20-30%) of heat with them.
In comparison, condensing boilers achieve extra energy efficiency by extracting the heat that would typically be lost from the carbon dioxide and water vapor. This collected heat is then used to pre-heat the water before it returns to the boiler.
At Hunt Heating we stock the Immergas Intec System and Combi Internal and External models which are efficient condensing boilers. The combination boilers afford you the ability to provide all hot water requirements from one, reliable source.
