Central Heating Boiler | Boiler - Hot water boiling system​


A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation.

    Two houses but only one boiler?

    Evening All, I have a customer who wants a modern oil boiler fitting to replace his ancient one. The big problem is he's divided his house into two with a holiday cottage next door.
