Worcester's gas, oil and LPG ranges consist of regular boilers, combination boilers and system boilers; these are wall-hung, floor-standing or externally sited. Worcester's solar water heating range was released in 2005, with the ground source heat pump range being released in 2007 and the air source heat pump range being released in 2008. [10]
return-tube boiler: fire-tube boiler with multiple small fire-tubes that reverse the direction of gas flow within the boiler. Individual tubes are not folded: there is usually a furnace, a combustion chamber that reverses the flow, then the tubes return from that. The Scotch is a well-known example of this type.

One advantage of a boiler is that the furnace can provide hot water for bathing and washing dishes, rather than requiring a separate water heater. One disadvantage to this type of application is when the boiler breaks down, neither heating nor domestic hot water are available. Air convection heating systems have been in use for over a century.
Fire crews were dispatched to the 370 Main St. building in response to a master box at around noon Wednesday, Worcester Fire Assistant Chief Adam Roche said. Firefighters heard reports of a fire ...
Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.

The thermal expansion is from top to bottom and with the usage of grate firing the grate firing the thermal expansion difference is minimised there by manifesting the sealing between grate and the boiler. The shorter path of water supply to the riser tubes leads to faster and more reliable operation on different loads and a quick start up. [1]
