By-pass tube De Dietrich 7680825

The by-pass tube is a crucial component in many heating systems, allowing water to circulate around the boiler even when radiator valves are closed. This helps maintain a minimum flow rate, protecting the heat exchanger from overheating and ensuring stable operation. Ideal for system balancing and maintenance, this tube is often used during installation or replacement of boiler spare parts. Its precise design ensures compatibility with a range of setups, making it a valuable addition to any heating engineer's toolkit for efficient system management.
