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 flow rate comparable to that of 65 kW boiler used with a 250 litre storage cylinder. The SE system operates like a traditional combi system but has two added Zenex innovations to give both flue gas heat recovery from the Zenex GasSaver and also a high DHW flow rate capability over selected period...

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 gases into a condensate store of some 7 litres. The incoming cold mains water passes through one heat exchanger in the store and another in the flue and heat is transferred so as to pre-heat the DHW. The water is heated to a temperature as high as 80C after which it is mixed with cold mains water to red... [read full article]
