condensing gas boilers overview
If you have access to mains gas, then gas will undoubtedly be the best and cheapest option to provide most of your heat. In a gas-fired condensing boiler, the water is heated through the heat of combustion, just as with non-condensing boilers. The resulting flue gases are normally passed into the chimney. As a result, the energy contained in the flue gas is lost. However, condensing technology exploits these gases, which consist to a large extent of hot water vapour. It extracts the flue gas heat and feeds the energy obtained into the heating circuit. In order to gain energy, water vapour must condense. It does this at a temperature of below 56 °C. The condensing boiler cools the steam through a specially designed heat exchanger. The energy gained is used to preheat the cold heating water. The hot water then passes into the primary heat exchanger where it is heated further to reach the desired temperature. During this process, small amounts of waste water occur which must be disposed of. The acidity of the waste water is so low that it can be conducted into a normal drainage system without further neutralisation.
Access to mains gas?
Gas-fired condensing boilers are normally your best and cheapest option when you have access to mains gas. Gas systems can be very successfully combined with solar thermal technologies, but are only normally financially viable when you have a large demand for hot water. If you are off the gas grid, LPG is an option, but not normally the most cost effective one when used to produce very large amounts of heat. LPG can be combined very successfully and cost effectively with an air source heat pump, to provide back up and to cover the very coldest 20% of the year. LPG can also win the argument when clients are looking for very fast response times and where convenience is paramount.
what is biomass?Biomass is biological material derived from living, or recently living organisms. In the context of biomass for energy this is often used to mean plant based material, but biomass can equally apply to both animal and vegetable derived material.
why use biomass?Biomass is a renewable, low carbon fuel that is already widely available throughout the UK. Its production and use also brings additional environmental and social benefits.
but is it really sustainable?Yes! As plants grow, each molecule of carbon dioxide they absorb from the air ends up as one atom of carbon in the plant, and two atoms of oxygen which are returned to the atmosphere. When the biomass is burned, each atom of carbon combines with two atoms of oxygen to give one molecule of carbon dioxide.
what type of boiler?There are many different types of biomass boilers available, to suit every application so it may be easiest to first consider the three different types of fuel – wood pellets, wood chip & logs.
biomass is often chosen for older houses requiring large amounts of heat
Take advantage of the Renewable Heat Incentive to cover the cost of your transition to biomass. With the current Domestic RHI payments set at £0.122 per KWh, this could mean annual payments of over £3,000, for 7 years, for a standard family house with a heating requirement of 25,000KWh indicated on the EPC. Combine this with interest free loans, significantly reduced fuel costs when compared to oil, LPG or electricity, the financial arguments to transition to biomass, are worthy of very serious consideration. To find out more click here, or get in touch. For Non-Domestic installations the RHI payments last for 20 years and the return on investment can be very significant.

what we do
Green Star Energy Solutions Ltd. is a is a company that specialises in taking a holistic look at the specific energy requirements of your home or business and matching this to a perfect renewable solution, where viable. We are a small renewable energy company, whoes objective is to reduce the energy bills of rural householders and businesses, enabling our clients to capitalise on the RHI and other government incentives, while reducing their CO2 emmissions. As a new company, reputation is everything to us, and we aim to earn a the best reputation, and exceed the expectations of our clients. We were established in 2014, with the main objective of addressing the large number of properties in the central belt that do not have access to mains gas, and are running on oil of electric heating systems. With the introduction of The RHI in April 2014, it has never before been so financially beneficial for house holders and businesses to move over to renewables – we’d like you to help you with this transition!
