Abstract
A boiler is disclosed comprising a heat exchanger having a plurality exchanger modules which are plugged in upper and lower headers connected in the heating circuit of a central heating system. The headers are secured to the rear wall of a casing and the modules are slidably mounted in guideways in the casing. Upper and lower latch bars are biased to their latching positions for preventing the modules from being uncoupled with the headers under pressure in the heating circuit. The exchanger modules may be installed and removed separately without the need of any tools.
Claims16
A gas- or liquid-fired hot water boiler for a central heating system, said boiler comprising a housing containing a combustion chamber;
- a heat exchanger communicating with said combustion chamber and connected between an inlet header and an outlet header adapted to be connected respectively to a return pipe and a supply pipe of a central heating circuit;
- and gas flue means for exhausting combustion gases, the improvement wherein:
- said heat exchanger comprises at least two plug-in exchanger modules, means for coupling each of said modules to each of said headers, and hand-operable latch means cooperable with said exchanger modules for locking said exchanger modules in their plugged-in position.
