Grants for a hot water boiler

Take advantage of Énergir’s grants for natural gas boilers – the most effective hot-water heating solution. With its precision, reliability, speed and energy performance, the natural gas hot water boiler helps you improve your building’s performance while reducing your energy bill.

The advantages of a condensing boiler

Condensing boilers reuse part of the available latent heat energy, which makes them highly energy efficient.

To benefit from the high efficiency due to condensation, the boiler must be installed on a heating system that provides a return water temperature to the boiler of 55 °C (131 °F) or less. The indoor/outdoor control of temperature via an external sensor also optimizes the operation of the boiler for space heating applications.
