Traditional heating systems are among the numerous sources of pollution. The last few decades have made this realisation a reality.
Traditional boilers are known to experience dangerous leakages of carbon monoxide and this can lead to poisoning. The air pollution from the waste gases emitted by these boilers depends on the fuel used to produce heat. Fossil fuels have always powered heating systems, and this has been one of the major contributors of air pollution. Despite many boilers relying on fossil fuels, people are now embracing green heating solutions.
Utility bills usually seem high after long winter months and have a tendency to come when least expected. An inefficient boiler is a major reason for such high bills.
Replacing an old boiler system with a green system can be expensive to install but is cheaper to run in the long-term. Thus an eco-friendly boiler is ideal for reducing your carbon footprint and a smart money saver.
Benefits of Eco Gas Boilers
Experts in the heating, ventilation, and air conditioning industry (HVAC) have to contend with the
challenge of constantly evolving technology. Some of the benefits of this alternative option for heating include:
Reduced emissions – Eco boilers have made it easy for HVAC engineers to comply with emission protocols. These boilers are engineered in a way that protects both the end user and environment.
Highly efficient – State of the art technology for manufacturing eco-boilers help reduce heat loss and improve heat transfer. Boiler controls such as thermostatic radiator valves can control room temperature more efficiently.
Maximum fuel-cost savings – Green boilers use less fuel for the same amount of work. With an energy rating of 90%, you’re sure to make significant savings in the long run.
Smart design and innovation – Advanced design and engineering have allowed the production of smaller boilers that take up less space for installation, and less noisier to operate.
Types of Eco Boilers
There are two main types of eco boilers – biomass boilers and condensing boilers. They’re engineered to help reduce your carbon footprint.
Eco Biomass Boilers
To produce heat in a biomass boiler you will need to burn wood and other renewable organic materials.
In contrast to older wood-burning stoves and fireplaces, modern biomass burning stoves are more efficient for water heating needs. Automatic biomass boilers can also control the amount of air and fuel needed to produce heat. However, you will need a bigger space to store the boiler together with firewood and logs for fuel.
Eco Condensing Boilers
Most new boilers these days are the condensing type. A-rated condensing models will see you exploit the available scrappage schemes. Modern boilers are more superior and efficient unlike traditional guzzlers as they smartly recycle heat that would be wasted.
You can power a condensing boiler by either gas or oil. The boilers come in various sizes and are compact enough to fit in different sites. They also require minimum maintenance. As a result, many homeowners are switching to condensing boilers due to their practicality. There are three types of condensing boilers:
- Combi boilers: Combination boilers are the most common type and are popular for running both your central heating and hot water from one unit. They don’t need a separate hot water storage cylinder or cold water feed cistern and therefore take up less space than heat only boilers. The main disadvantage is the time lag between turning on the tap, getting hot water, and limited flow rate. This boiler is most suitable for larger homes.
- Heat only boilers: This boiler type is ideal for powering radiators. They need to be connected to a separate hot water storage system that has a hot water cylinder, and a cold water cistern. This boiler is suitable for larger homes.
- Oil boilers: They’re less common than gas boilers but equally efficient. They’re more common in the countryside where homes are not connected to the main gas supply. Most oil boilers are fueled by kerosene and are floor standing. They also come in both combi and heat only condensing models.
Is it Time to Change Your Boiler?
Choosing the right time to replace your boiler is important not only for future energy savings but also for a greener and clean environment. Always take the advice of a qualified engineer if he advises you to consider replacing your boiler.
Fuel Efficiency – Your energy bills can contribute up to 60% of your boiler expenses each year. If you suspect your energy bills are high in relation to the functioning of your boiler, consider switching to an eco-friendly type.
Boiler emissions – Newer eco-friendly boilers have lower emissions and still maintain a high-efficiency rate to do the work required without worrying about AQMD limits.
Innovative designs – Eco boilers are engineered to prevent energy loss which occurs during the standard combustion process. Boiler inefficiencies such as radiation loss, start-up loss, and exhaust loss make it more expensive to run a boiler. Eco boilers are insulated against this kind of losses.
Which is the Best Brand Type?
A brand to avoid is Keston as 80% of owners have had issues with this boiler within 4 years of buying it.
This range offers a high A-rated efficiency. It comes in various sizes to suit different households. For example, the ecoTEC plus 824 is suitable for medium-sized, semi-detached homes. EcoTEC plus 937 is suitable for detached three to four bedroom units. The ecoTEC range is easy to use and service, and provides a combination of high efficiency, low nitrogen oxide emissions, and ease of use.
Glow Worm – Part of the Vaillant Group
Produces eco-friendly heat pumps and solar systems. The Glow-Worm Ultracom is A-Rated with over 90% efficiency. It also ticks the right boxes for efficiency, low emissions, ease of installation, servicing and use.
Grant Vortex Pro Combi 26
This A-rated 90% efficient model comes in various sizes to suit your home needs. The oil-powered Grant Vortex Pro Combi 26 loses less heat from its casing and emits less nitrogen oxide. Proper maintenance of your gas boiler could become law in future.
The big question is whether gas will still be the fuel for the future
Despite its fossil nature, gas experts predict it will still be around, as we will continue to innovate and make it as green as possible. 80% of UK homes are connected to a gas supply thus it may be a while before an alternative purely renewable fuel for heating homes is adopted.
