Baxi and Zenex promote technologies that improve energy efficiency of domestic boilers(12/03/2009)
The Zenex GasSaver is a flue gas heat recovery device that sits in the flueway on top of the boiler and recovers normally wasted heat energy from the flue gases. The recovered heat is stored in the GasSaver unit and used to pre-heat the cold water that supplies the domestic hot water (DHW) system. The Zenex SuperFlow is an extension to the GasSaver, which uses a 25 or 50 litre thermal store to provide an additional pre-heat function. This heat store allows a combi boiler to deliver hot water ... [more]
EST recognises the Zenex GasSaver under its Energy Saving Recommended scheme(15/10/2008)
The Energy Saving Trust (EST) has established a new product endorsement category, "Passive Flue Gas Heat Recovery Devices and Systems". It has also recognised the Zenex GasSaver under its Energy Saving Recommended scheme. The GasSaver is a simple device that fits above the boiler and recovers heat from the flue gases. It effectively condenses the steam in the gases and preheats the incoming cold main. The heat normally lost from the most modern boilers can often be seen as plumes of steam or... [more]

Zenex Super Efficient System increases DHW flow rate and reduces hot water cost(07/12/2007)
Zenex Technologies, creators of the Zenex GasSaver heat recovery device, has applied its patented CoolFlue technology to develop a new domestic hot water system that can save households over 50% of their domestic hot water (DHW) costs and provide, at the same time, a 100% increase in the DHW flow rate. The Zenex Super Efficient (SE) System is a domestic hot water system that provides flexibility and a high efficiency from its standard 32kW combi boiler together with an ‘on-demand’ high DHW ...

GasSaver reduces gas consumption required for domestic hot water(24/04/2007)
Trials show that Zenex Technologies’ GasSaver can reduce gas consumption required for domestic hot water (DHW) by up to 50%, representing significant cost savings for consumers and making a useful contribution to protecting the environment. This boiler flue attachment that recovers heat from the waste combustion gases and uses it to pre-heat the DHW supply has been awarded a patent from the UK Patent Office. The Zenex GasSaver uses a flue gas condenser to condense the water in the flue gase... [more]
