Despite their name, modern day warm water boilers do not actually boil water in the traditional method. Rather,they heat water to a certain temperature to be used in conjunction with a forced air heating system. In fact, most new hot water boilers double up as forced air heaters and in some cases, steam boilers too. However, older homes with elderly radiators may still have water boilers that really only boil water to produce steam.
As such, if your home has a water boiler although not a forced air heating system then the boiler will simply be a storage tank filled with water that will eventually require replacement or repair. Water boilers must, therefore, always be stored below a good enough source of water so they can keep producing steam without getting over-stocked. The most important disadvantage of a water boiler is that it uses around ten times as much water as a forced air heating system. Also, water boilers are a lot more energy efficient compared to their forced air cousins and so, may actually be cheaper to run in the long run.
The essential advantage of a water boiler however, is the use of water instead of air to produce heat. Provided that you have a steady source of water, the boiler will never stop producing warmth. A water boiler doesn’t need a good deal of room because it’s very simply hung from your roof or inside the walls of your home (if it’s attached to the ceiling). If you decide to put in a water boiler, then you will need to hire a plumber to install it to you. In case you have an old radiator then the very first thing you should do is remove any damaged tubes and pipes. A busted tube will not heat your water and also will just cause your water boiler to run inefficiently – a busted radiator may even lead to damage to your property.
