Low Carbon Heating Systems to Choose for Eco-Friendly Homes

Making the proper choice for warming your house is no easy task. Similar to choosing the appropriate attire for a big occasion, there are many factors to consider and there are instances when you must make a quick decision, particularly when the ideal installation time is drawing near. Although a little daunting, don’t worry—we’ve got you covered.

And guess what? If you’re eligible, the UK government might just treat you to some central heating grants to help keep your home energy-efficient and cosy. Especially with the recent uptick in gas and energy prices, it’s crucial to consider sustainability into your calculations. 

Here, we’re going on a journey to discover the various ways homes stay warm in the UK. We’ll be sorting through the options to find the best one. Think of it as a smart move for your wallet in the long run! Let’s dive into the warmth.

1. Heating Boilers

When it comes to heat pumps, you’ve got two buddies to pick from: air source and ground source. It’s like having a menu with two delicious options for keeping your favourite taste and flavour. 

And you know what’s cool? They’re not just good for the planet; they’re also a breeze to install and won’t break the bank! Let’s know each type a bit with pros and cons of each.

a. Air Source Heat Pumps

Air source heat pumps are like magicians in the heating game. They work a bit like ground source heat pumps, but instead of pulling energy from the earth, they snag it from the air. What’s cool is that they keep working their magic even when the temperature drops way below zero – now that’s impressive!

Though they use electricity to run, here’s the sweet part: they produce more energy than they use. It’s like getting a bonus in the energy efficiency game, around three times!


  • Easy Installation, quick and straightforward setup.
  • Versatility in both heating and cooling for year-round comfort.
  • Low Operating Costs
  • Compact and doesn’t require extensive space.


  • Variability: Performance can be influenced by external temperatures.
  • Noise Levels: Some units may generate noise during operation.
  • External Aesthetics: Outdoor units may impact the visual appeal.

b. Ground Source Heat Pumps

Ground source heat pumps are like the undercover agents of heating, with a sneaky network of underground pipes. A special mix of antifreeze and water cruises through those pipes, slurping up energy from the earth. 

This energy is like a power-up, warming up water that goes to your taps or radiators, or gets saved for a cosy moment later.


  • Consistent Efficiency: Maintain high efficiency year-round.
  • Quiet Operation: Generally quieter than air source heat pumps.
  • No Outdoor Space Impact: Buried underground, preserving aesthetics.
  • Long Lifespan: Typically have a longer lifespan.


  • Installation Costs: Initial installation can be expensive.
  • Space Requirements: Requires sufficient outdoor space.
  • Complex Installation: Installation involves ground excavation or drilling.
  • Performance Variability: Efficiency may decrease in very cold weather.

2. Solar Heating

Harnessing solar power for heating is not just effective; it’s the top choice if you’re all about being eco-friendly and kind to the environment at home. A solar heating system taps into the sun as its main source, waving goodbye to the need for natural gas or electricity. 

It’s like having a system that’s pollution-free and emits no greenhouse gases once it’s up and running. This system uses cool gadgets to turn solar energy into heat and electricity, storing it up for whenever you need a toasty home. It’s like having the sun on speed dial for warmth!


  • Eco-friendly source – zero carbon emission
  • Substantial saving on energy bills
  • No additional cost (except little maintenance)


  • Requires highly skilled professionals for installation and maintenance.
  • Immensely heavy on the pocket.
  • Always need storage and backup maintenance.
  • Weather dependent

3. Natural Gas Heating

These heating units are champs at running safely without being energy guzzlers. But, like all heroes, they need a little check-up every few years to keep performing at their best. Regular checks and servicing are the secret to their long-lasting efficiency!


  • Cost-Effective: Often cheaper than electricity for heating.
  • Quick Warm-Up: Heats up spaces quickly.
  • Availability: Widely available in many areas.
  • Reliable: Provides a steady and reliable heat source with less carbon emissions.
  • Versatile: Works for heating and cooking.


  • Non-Renewable: Natural gas is a finite resource.
  • Infrastructure Required: Requires gas lines for installation.
  • Safety Concerns: Potential safety risks if not handled properly.

4. Underfloor heating

There are two cool types to choose from: warm water underfloor heating and electric underfloor heating. It’s like having a menu of warmth options for your floors!

a. Water-based heating

It’s like having a secret network of pipes playing hide-and-seek beneath your floorboards. These pipes team up with a heating system, like a trusty boiler or a heat pump. 

Now, here’s where the magic happens – warm water gets sent on a journey through those pipes, turning your whole room into a cosy paradise. It’s like having a toasty floor hug from below!


  • Even Heat Distribution: Uniform warmth across the entire floor.
  • Energy Efficiency: Operates at lower temperatures, enhancing efficiency.
  • Space-Saving: Eliminates the need for visible radiators.
  • Comfortable Warmth: Provides consistent and luxurious warmth.
  • Design Freedom: Offers flexibility in interior design.


  • Installation Cost: Initial setup can be relatively expensive.
  • Installation Time: Takes time to install, causing potential disruptions.
  • Flooring Restrictions: Certain flooring materials are more compatible.
  • Maintenance Complexity: Repairs may require lifting flooring.
  • Initial Warm-Up Time: Slower to heat up compared to some systems.

b. Electric heating

Electric underfloor heating operates in a similar fashion to its water-based counterpart. Instead of pipes, this system features installed wires that heat up when the system is turned on. It’s like having a cosy warmth network right under your floor. 


  • Efficiency: Almost 100% of electricity is converted to heat.
  • Installation Ease: Often simpler to install than other systems.
  • Individual Room Control: Allows independent temperature control for each room.
  • No Emissions: Produces no direct emissions.
  • Low Initial Cost: Can be more cost-effective upfront.


  • Operating Costs: Typically higher long-term operational costs.
  • Energy Consumption: Can be less energy-efficient than some systems.
  • Maintenance Challenges: Repairs might involve complex lifting flooring
  • Limited Capacity: Suitable for small spaces and certain flooring types only.
  • Dependency on Grid: Relies on electricity grid stability.


These heating champs we mentioned are like the wizards of warmth for your home. They’re eco-friendly, won’t make a mess, and with some TLC, they stick around for the long haul, saving you tons on bills. Pick the one that suits your vibe, and always call in the experts to work their magic!
