Item number: 2500000136894 View all Tonzon products > View more: Reflective foil > Boiler foil from Tonzon Boilers and water heaters are often already insulated, yet they still frequently reach temperatures of over 30 degrees Celsius on the outside. Because they are so much warmer than the surrounding area, they constantly lose heat. This means they need to be heated more to maintain the desired temperature. TONZON has a simple solution: hang reflective foil around the boiler to block heat loss. The foil can be attached with magnets. This way, it can be easily removed when it's time for maintenance.
