The new type of boiler is a condensing boiler. Condensing boilers are more efficient than traditional boilers, as they are able to capture and reuse the heat that is normally lost in the flue gases. This means that they can operate at higher temperatures and still achieve the same level of efficiency. Condensing boilers also have a much lower carbon footprint than traditional boilers, making them a more environmentally friendly option. Additionally, condensing boilers are quieter and require less maintenance than traditional boilers.
