It heats your central heating system directly and produces hot water for your cylinder.
A system boiler heats your central heating system directly and produces hot water for your cylinder. A system boiler, just like a regular (conventional) boiler works on the principle of stored hot water. However, a system boiler differs from a regular boiler in some important respects.

In system boilers, for example, the pump is built into rather than installed away from the boiler. Pumps in system boilers also mean that hot water is produced quickly and more economically. Expansion vessels are also built into system boilers, replacing the need for a feed/expansion tank to be installed in a loft. Safety valves, air vents and programmers are included in system boilers. System boilers. If you live in a home with more than one bathroom or require more hot water than can be provided by a combi boiler, then a system boiler could be your perfect heating and hot water solution. A system boiler pumps hot water to the radiators and a sealed hot water storage cylinder. Most of the major components of the heating and hot water system, including the pump and expansion vessel, are built into the boiler, making installation easier, tidier and more efficient, and also simplifies servicing Secondly, the hot water is pumped from the system boiler through the heating system to the radiators and hot water cylinder, resulting in a fast response and more economical running costs. The system boiler removes the need for a feed and expansion cistern. An example of a central heating and hot water system layout using a system boiler with an open-vented hot water cylinder.

Hot water from the boiler can also be directed to an indirect water heater to supply your home with hot water, to a snow melting system, or even be used to heat a pool. 1  Heat is evenly distributed in a room: no drafts or hot and cold spots as with forced air. Search. Hydronic Heating-What it is and why you want it! Hydronic heating is a safe, comfortable, economical and flexible way to heat any home. Hydronic systems circulate hot water through warming baseboards, radiators and/or radiant tubing in your floors or ceilings. Maintenance of water pressure means that system boilers are ideal for larger properties where demand for constant hot water is high. Several taps can be used simultaneously without a drop in water pressure. These types of boilers also usually large have large storage tanks, ensuring a ready supply of hot water. Expansion vessels are also built into system boilers, replacing the need for a feed/expansion tank to be installed in a loft. Safety valves, air vents and programmers are included in system boilers. The pressure vessel of a boiler is usually made of steel (or alloy steel), or historically of wrought iron. Stainless steel, especially of the austenitic types, is not used in wetted parts of boilers due to corrosion and stress corrosion cracking. 1 Flash boiler: A flash boiler is a specialized type of water-tube boiler in which tubes are close together and water is pumped through them. 2  A flash boiler differs from the type of mono-tube steam generator in which the tube is permanently filled with water. Furnaces and Boilers. Upgrading to a high efficiency furnace or boiler is an effective way to save money on home heating. Most U.S. homes are heated with either furnaces or boilers. Furnaces heat air and distribute the heated air through the house using ducts. 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. Replacing Your Furnace or Boiler. Although older furnace and boiler systems had efficiencies in the range of 56% to 70%, modern conventional heating systems can achieve efficiencies as high as 98.5%, converting nearly all the fuel to useful heat for your home.
