Genersys Home Energy Heating System
Genersys Home Energy Systems synchronise the benefits of condensing boilers & solar panels, developed in order to provide a sustainable, efficient and "green" solution to the problem of providing heat and hot water in domestic homes throughout the United Kingdom.
Genersys technology includes real time modulation of the heat exchange pump, automatic adjustment of the boiler load to the outside temperature, sophisticated digital controllers and specially insulated heat exchange pipework.
No technology can, in the United Kingdom, provide all a domestic household's energy from renewable sources but the Genersys Home Energy System will go a long way to provide around 70% of a household's energy using the emission-free, green, clean energy of the sun.
Energy inefficiency causes environmental damage but it can be difficult to target budgets in a way that promotes energy efficiency and gives value for money. There are some organisations, such as those responsible for social housing or smaller premises in different locations where it is important to provide not only value for money but also an energy system that enables the end user to afford his or her energy bill.
This affordability is critical. Building a house that is 100% environmentally efficient is useful as a learning exercise but not terribly helpful if you have homes built years ago, occupied by people who cannot afford to keep warm or by occupants on a strict budget. One solution is to look at all the components in a home energy system and make them work together in the most efficient way.
There are three major components of an integrated home energy system: solar technology, a good gas condensing boiler, and a hot water store, which when synchronised can provide optimum money-saving efficiency.
Modern solar water heating technology is robust and mature. It collects light (both direct sunlight and the diffuse light that is available on a very cloudy day) and turns the light into heat on the absorber plate of the tubes. Over 96% of the light can be converted into heat. An absorber plate contained within a near perfect vacuum or a highly insulated panel, allows it to accept light but prevents any of the heat from escaping. The heat is pumped into the water store or direct into the boiler.
Traditional gas boilers are very wasteful of energy. They use a tremendous amount of energy making latent heat, which ends up heating the atmosphere when it is discharged outside into the fresh air by a flue. Traditional boilers were designed when fossil fuel was cheap and when no one had made the connection between dirty air and poor health or the connection between heavy fossil fuel use and global warming.
These days things are different. The best gas condensing boilers discharge hardly any latent heat into the air. Instead, the latent heat that a traditional boiler would discharge into the air is condensed, using superheated steam, and recovered for use as energy to heat the home. As a result, the best system does not waste expensive gas in order to maintain high heat in the home. This significantly reduces heating costs.
But the best gas condensing boilers do more than this. Most of the very best quality range gas condensing boilers operate at a typical efficiency of 86% but by using the special and exclusive variable controlled output some can achieve up to an amazing 98% efficiency rating.
In order to achieve the optimum efficiency from a gas condensing boiler it is necessary to control the temperature of the water returning to the gas boiler. This is achieved by adjusting the boiler output or the pump speed or by a combination of both.
Let us take an example: when you use a gas or electric fires to heat up a building, as outside temperature gets warmer you turn the fire down. This not only allows the room to maintain the right temperature but also reduce energy costs. If you were using gas central heating you could not turn a traditional boiler output down by adjusting the gas valve.
However, some systems incorporate an integral compensating and modulating digital controller that automatically adjusts the output of the boiler according to the outside temperature and the boiler load requirements. This integrates with a modulating variable speed air pump so that the right amount of air is mixed with the gas for optimum burning efficiency, according to load requirements .
The air and gas mixture in a well-adjusted condensing boiler means that combustion should occur almost without visible flame and with the lowest level of pollution possible. There is no need for a wasteful pilot light.
The final piece of this technology is a variable speed water pump to circulate hot water through the radiators. A critical factor in any heat exchange operation is the speed at which the water is pumped. Pump too quickly or too slowly and there is inefficient heat exchange.
The best quality water store replaces the traditional immersion heater. It is larger than the traditional system in order to take advantage of solar energy. Wherever possible (this may to an extent be determined by individual water pressure and the design of a building).
And the result of all this technology? Well, it will not provide 100% free energy but it should provide savings of between 60% and 80% of the energy bill and around two tonnes of carbon dioxide per system per household or equivalent user of energy in business premises each year.
Clearly, large savings of emissions are desirable, but there are many households where fuel poverty is still an issue and use of this technology, giving rise to affordable fuel bills, is likely to be considered by those responsible for social housing and smaller commercial premises.
