   A heat exchanger brings the heat from the burner to the water. Its job is to bring heat to the water without having contact with the water, similar to boiling water in a pot. An exhaust stack takes the hot gases and transfers them away from the boiler. Boiler controls are there to make sure the hot water or steam is produced in a safe way. [5]

3. Electrode boiler - Wikipedia

   en.wikipedia.org/wiki/Electrode_boiler

   All electrical energy is converted to heat. An electrode boiler has a very quick response time. As it doesn't directly generate pollution, no pollution control system is needed. [2] As compared to other boilers, electrode boilers experience little thermal stress. [3] Electric boilers have few components making it easier to control and maintain.

4. Tankless water heating - Wikipedia

   en.wikipedia.org/wiki/Tankless_water_heating

   Combination or combi boilers combine the central heating with domestic hot water (DHW) in one device. When DHW is used, a combination boiler stops pumping water to the heating circuit and diverts all the boiler's power to heating DHW.

6. Water heating - Wikipedia

   en.wikipedia.org/wiki/Water_heating

   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 and direct cylinders, respectively. Additionally, if these cylinders form part ...

   Chillers and cooling towers are used either separately or together as means to provide water cooling, while boilers heat water. A recent innovation is the chiller boiler system, which provides an efficient form of HVAC for homes and smaller commercial spaces. A hydronic fan unit heater used for maintaining warmth within an industrial setting.
