All solid fuel stove circuits centre around one basic principle: hot water rises through cold water (hence why when you swim in the Med the water gets colder if you dive down a few metres). In the scribble above the stove has been lit and the water within the stove (in a metal box within the stove or in the jacket of the stove) heats up.
Read MoreThe prismatic type gage glass with which most new boilers are equipped is very unlikely to break and is much easier to read, as the water appears black in the glass while the steam is white. The water gage glass must be looked at regularly every few seconds, as the water level can change quickly, especially in watertube boilers.

Read MoreTypical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers, Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel, which increases flue gas losses.
Read MoreYour domestic hot water would have been heated in the back boiler then passed back to the cylinder - eventually providing a cylinder full of hot water heated 'directly' by the back boiler. Such systems were typically unpumped - relying on gravity circulation (also known as 'Thermosiphoning' where hot water rises, cooler water falls creating
Read MoreBoth the water tube and the shell boiler operate through a three-pass system, although the following information only applies to shell boilers. Within the boilers, the flame tubes sit in water. The hot gas enters the flame tubes (first pass) and continues through an internal reversing chamber that reverses the flue gases, allowing them to move

Read MoreAutomatically operated fuel valves shall not be designed with integral manually operated by-passes unless such by-pass is of the constant pressure type. (j) The electrical circuit for boiler controls shall not exceed 120 volts and shall be 2-wire with 1-conductor grounded and have the controls in the ungrounded conductor.
Read MoreThe control of the boiler water level is tricky and even the best tuned control systems cannot always prevent a low-water condition The "water level " in a pressure vessel is actually a fairly unstable compressible mixture of water and steam bubbles that will shrink and swell with pressure changes and will actually shrink momentarily when
Read MoreAs you can imagine, the boiler (and therefore the hot water function) has to be 'on' before the heating will work. This is taken into account by the type of programmer fitted to semi-gravity systems - hot water alone can be selected but not central heating alone. Central heating can only be selected when hot water is also selected.
