Water heating - Wikipedia

Where hot-water space heating boilers are installed, domestic hot water cylinders are usually heated indirectly by primary water from the boiler, or by an electric immersion heater (often as backup to the boiler). In the UK these vessels are called indirect cylinders, or direct cylinders, respectively. Additionally, if these cylinders form part of a sealed system, providing mains-pressure hot water, they are known as …

Boilers can be classified into the following configurations: Pot boiler or Haycock boiler/Haystack boiler: A primitive "kettle" where a fire heats a partially filled water container from below. 18th century Haycock boilers generally produced and stored large volumes of very low-pressure steam, often hardly above that of the atmosphere.These could burn wood or most often, coal. Efficiency was very low. Flued boiler …

Boilers heat water, and provide either hot water or steam for heating. Steam is distributed via pipes to steam radiators, and hot water can be distributed via baseboard radiators or radiant floor systems, or can heat air via a coil. Steam boilers operate at a higher temperature than hot water boilers, and are inherently less efficient, but high-efficiency versions of all types of furnaces and boilers are currently …

Electric boilers use electricity to operate the heating element which then provides central heating and hot water in the home. Electric powered boilers are an ideal solution for properties which have restricted or no access to the mains gas supply. One main benefit of electric boilers is that they are energy efficient, no separate flue or chimney is required meaning that heat is not lost and they do not require the burning …

This is the most common form of heating in the UK. A single boiler heats up water that is pumped through pipes to radiators throughout the house as well as providing hot water to the kitchen and bathroom taps. Most boilers run on mains gas, but in areas where mains gas is not available, the boiler can run on oil, LPG (tank gas), coal or wood
