Save energy with a Boiler Gas Saver
New Central Heating Boilers today are the most energy efficient that they have ever been. A new A-rated high efficiency condensing boiler will boastan efficiency rating of around 90%. However, a lot of heat is still lost through the flue outlet.
A new innovative product has been designed to capture this heat and use it to help make hot water for domestic use. Designed and manufactured in Britain, the Zenex GasSaver gives more usable hot water than a usual solar hot water system.
The GasSaver is fitted to the top of a domestic boiler and works by capturing waste heat from the exhaust gases to warm the water in the tank. These are then passed through a flue and pumped back into the system, which preheats the cold water going into the boiler.
The temperature of this water is kept below 50 degrees, giving an increase in efficiency over typical condensing boilers, whose performance drops if the water is above that temperature. The result is a boiler that uses less energy.
Installation should be relatively straightforward, a basic knowledge of plumbing should suffice. Another bonus is zero maintenance (no moving parts) or electrical supply (no electrician). New-builds and total refurbs may be the GasSavers natural home. It may be difficult to install onto existing boilers, unless you are ready for a bit of hassle. Another consideration maybe the GasSavers unsightly apprearance. Aesthetics shouldnt really figure when saving money (and the planet) but the unit does look a little uncomfortable on top of the boiler.
According to the manufacturers, the cost of the unit could be recovered within 3-5 years (compared to 20-40 years for Solar) With energy prices thought to rise by up to 25% in the next five to ten years installing a GasSaver (which could save you 50% on your gas bill) may be a wise investment.
