Despite their title, modern day warm water boilers do not really boil water in the standard manner. Ratherthey heat water into a particular temperature to be utilised together with a forced air heating system. In reality, the majority of new hot water boilers double up as forced air heaters and sometimes, steam boilers as well. However, older houses with elderly radiators may still have water boilers that really just boil water to create steam.
Water boilers have to, therefore, always be kept below a good enough supply of water so thatthey can keep producing steam without becoming over-stocked. The main drawback of a water boiler is that it uses around ten times as much water as a forced air heating system. Also, water boilers are much more energy efficient compared to their forced air cousins and so, may even be more economical to operate in the long run.
The essential benefit of a water boiler however, is the use of water instead of air to create heat. As long as you have a steady supply of water, the boiler will never stop producing heat. A water boiler doesn’t need a lot of space as it is very simply hung out of your roof or inside the wall of your house (if it is connected to the ceiling). If you choose to install a water boiler, then you’ll need to hire a plumber to install it to you. In case you’ve got an older radiator then the very first thing you should do is remove any damaged tubes and pipes. A busted tube won’t heat your water and also will just cause your water boiler to operate inefficiently – a busted radiator can even cause damage to your property.
