Sustainability has long been a buzzword thrown around in climate change workshops and conferences. But it’s now become an issue that concerns almost everyone on the planet.

In this post, we’ll examine how embracing eco-friendly boiler solutions might help you save a penny while doing something positive for the future of humanity.

We’ll also explore at least two other lower-carbon emission solutions that you can adopt to help Mother Earth in some way.

What Are Eco-friendly Boilers?

Eco-friendly boilers are a type of boiler designed to maximize energy efficiency while staying environmentally friendly. Examples of eco-friendly (up to a point) boilers include electric boilers, condensing boilers, biomass boilers, hybrid boilers, and hydrogen-ready boilers.

One could be forgiven for thinking that eco-friendly boilers are truly green options that cause zero harm to Mother Nature. However, today’s boiler technology hasn’t advanced to a place where they’d release zero emissions.

Fortunately, scientists and researchers are working hard to address the hindrances that stand on humanity’s path to a sustainable, greener, cleaner, carbon-free future.

The Future of Eco-friendly Boilers: What Does It Look Like?

The future of eco-friendly heating systems looks pretty bright. As more efficient heating technologies emerge down the road, people will want to ditch their older, less efficient, and less reliable systems for better fuel converters, more environmentally friendlier, and better money-saving choices.

Government policy will definitely play a significant role in how the future of home heat production turns out. Governments such as those of the U.K. and U.S. are encouraging homeowners to switch to greener heating solutions. And it’s reasonable to predict that other governments will follow similar paths.

We might see a massive shift from less efficient heating and cooling systems to more efficient ones, such as heat pumps. And if market forces and other economic factors cause gas prices to increase by an appreciable margin, gravitating towards more cost-effective water and space heating technologies would be a no-brainer.

Different Types of Eco-friendly Boilers

There are at least five kinds of eco-friendly boilers, namely:

  • High-efficiency condensing boilers
  • Electric boilers
  • Biomass boilers
  • Hydrogen boilers
  • Hybrid home heating systems

Let’s briefly look at each of these eco-friendly boilers.

1. Condensing Boilers: Eco-friendly, But Not Exactly Green

Condensing boilers are greener/better for the planet compared to their non-condensing counterparts, but they’re not the most eco-friendly options.

Modern condensing boilers aren’t 100 percent green. They work by combusting fossil fuels such as gas. Which means they don’t have a zero carbon footprint. If you’re looking for a totally carbon-free home heating solution, definitely install a different system.

With that being said, some newer condensing boilers can be extremely efficient.

Some options have an energy efficiency rating of up to 94 percent, according to heatable.co.uk. No more than 6 percent of fuel gets released as exhaust fumes. And that’s amazing.

What Makes Condensing Boilers Eco-friendly?

According to IOPScience, boilers with a higher condensing fraction demonstrate a better thermal efficiency rating. Condensing boilers cool the water vapor in the exhaust gases/flue gases. As the water vapor condenses, the system recovers some of the lost energy as latent heat.

This recovered latent heat plays a super important job. It preheats your water before it gets back into the boiler. You’ll save some energy and money in the final analysis.

While an A-rated condensing boiler is still not a wholly green energy source, it’s still a way greener boiler compared to an ancient G-rated one operating at, say, 65 percent.

As a household that’d like to contribute toward environmental preservation while saving a buck, upgrading to a condensing boiler could make sense.

2. Electric Boilers: They’re Definitely Green, But…

They’re not 100 percent green, even though everyone says they are. To be clear, the best electric boiler converts pretty much 100 percent of the power they receive to heat and doesn’t emit carbon dioxide and other environmental pollutants. Also, no exhaust fumes are released from these eco-friendly boiler systems, and there are almost no energy losses.

If an electric boiler uses electricity generated using 100 percent renewable energy sources such as solar power or hydropower, that water heating system could be accurately described as completely eco-friendly, green, or clean.

Electric boilers could be 100 percent eco-friendly if the electricity comes from renewable energy sources such as water or solar power. However, electric power generation in the U.S. and many other countries isn’t a zero-carbon footprint affair. Most of today’s electric power comes from combusting fossil fuels.

Before you splurge on an electric boiler, ask yourself how reliable the grid in your corner of the world is and how much it costs. For many people across the world, using electricity to run electric boilers can be quite expensive. So this isn’t always a viable option for everyone.

3. Biomass Boilers: Can be Carbon-Neutral

Biomass boilers burn wood chips, logs, or pellets to produce heat that heats households. If communities can replace trees at a faster rate than they cut them down, biomass boilers could be a pretty clean heating solution.

Unlike conventional boilers that rely on fossil fuels for heat generation, biomass boilers consume organic materials, majorly wood.

If the government of the day has a stringent tree-planting policy where more trees are planted than are cut, then a biomass boiler could truly be a carbon-neutral home heating solution. However, people in many places around the globe don’t plant twice as many trees as they fell.

Deforestation has been happening for years, which is why many regions are seeing climate change outcomes that have never been observed before. According to NASA, the world is getting warmer at an unprecedented pace. The rate of change is faster than anything that’s been recorded over the past 10,000 years.

4. Hydrogen Boilers: Could They Become the Cleanest Heating Solution of the Future?

If and when home heating technology manufacturers figure out how to produce hydrogen without emissions, it will be possible to install a fully green hydrogen boiler.

At this juncture, hydrogen-powered boilers aren’t accessible to households. Currently, it’s impossible to produce hydrogen using completely clean hydrogen production processes.

Fortunately, the research and development departments of some companies are busy looking for ways to make hydrogen boilers.

Why would hydrogen-based heating systems be a great idea? When you burn hydrogen, you get a completely harmless substance: water vapor and zero emissions. 

These boilers of the future will let consumers burn hydrogen in the same boiler system they’re using today. Proponents argue that people would be more receptive to the idea of using a new fuel than having to rip out the existing installation for a new (and perhaps more expensive) one.

5. Hybrid Heating Systems

Hybrid home heating solutions are better for the environment compared to gas-fed boilers in terms of overall efficiency and longevity.

Hybrid heating systems bring together the strengths of a heat pump and a gas boiler, enabling consumers to access the best of both worlds. This smart home heating solution emits less carbon than a traditional option or a gas boiler.

It’s programmed to run the most efficient heating option at any one time, usually the heat pump.

Modern gas boilers are efficient, but hybrids are even more efficient. Maybe you should explore this idea further to determine if switching over would be worth it.

What About Traditional Home Heating Solutions?

Traditional home heating solutions work and many are still in use in homes. But they always give the environment a harsher thrashing compared to modern, more sustainable alternatives such as highly efficient, eco-friendly boilers.

Not only are conventional boilers less efficient, but you must combust more fuel to release the same amount of energy as a more sustainable solution.

Since you have to burn more fuel, your carbon emissions increase. Consequently, the Blue Planet suffers greater harm.

Did you say that your 65 percent G-rated boiler has seen better days but still works reliably enough? Fair enough, but it definitely wastes tons of energy, which isn’t good for the environment. You’re leaking money, quite literally.

Perhaps it’s time you replaced that old thing with an option that does more good for the environment while working more reliably for you.

Benefits of Eco-friendly Boilers

  • They’re better for the environment compared to less efficient options. They push out fewer carbon emissions, making them clearly the more rational choice for Mother Earth.
  • Your home becomes a more comfortable place to live since you’re counting on a more reliable water and room heater.
  • Since a greener boiler converts fuel to heat more efficiently, there’s less energy loss, which helps you save money.

Downsides to Using Sustainable Energy Solutions 

  • Sustainable energy solutions such as biomass boilers can lead to massive deforestation if not handled with care, worsening climate change.
  • Installation costs for heat pumps, hybrid boiler systems, and biomass can be pretty prohibitive for many people.
  • Some installations, such as biomass boilers, require lots of space. They may, therefore, not be the best lower-carbon heating system for tiny homes.

Other Low-carbon Heating Systems

  • Heat pumps
  • Thermal heating panels

Let’s take a closer look.

Heat Pumps: A Worthy Alternative to Existing Heating Systems

Credible data shows that switching from an existing inefficient home heating and cooling system to a heat pump can save the average single-family home about $557 per year on utility bills. Actually, in some places, such as West Virginia, people could save even more money, up to roughly $887.

The same dataset further asserts that replacing the existing heating and cooling technology could create millions of jobs, about 6.6 million4.

It’s estimated that changing to heat pumps could cut home heating-related carbon emissions by 142,000,0004 metric tons per year. This number translates to a 14 percent reduction4 in the home energy sector and a decrease in total U.S. emissions of 3 percent.4 

So, what prevents many homeowners from switching over to heat pumps? It’s mainly because heat pumps are pretty pricey, and gas prices aren’t too high.

If the government installs a program that incentivizes heat pump adoption in the future, people could abandon fossil fuels and inefficient heating and cooling systems for more eco-friendly boilers such as heat pumps.

Thermal Heating Panels

They aren’t the same as solar panel systems, but thermal heating panels (aka solar domestic water heating systems) rely on the sun’s energy to provide heating. And solar energy is a totally FREE, zero-carbon source.

Most systems like these are easy to integrate into the existing home heating infrastructure and can help you save a decent amount of energy over time. You will save money because this system can have you spending up to 60 percent less energy.
