Common myths about air source heating systems

Air source heating systems (ASHPs) are becoming an increasingly popular choice for homeowners across the UK. Known for their energy efficiency, eco-friendliness, and cost-saving potential, they offer an appealing alternative to traditional heating systems. However, despite their many advantages, several myths continue to cloud the understanding of this innovative technology. At Custom Renewables, we want to clear up these misconceptions and help our customers discover the real benefits of air source heating.

Myth 1: Air Source Heating Doesn’t Work in Cold Climates

Fact: One of the biggest misconceptions about air source heating is that it’s ineffective in cold weather. However, modern ASHPs are designed to operate efficiently even in freezing conditions. Thanks to advancements in technology and specially designed refrigerants, air source heat pumps can extract heat from the air even when temperatures drop as low as -25°C.

Although their performance may slightly decrease in extreme cold, ASHPs still outperform traditional heating methods, such as electric heating, and can effectively keep your home warm during the colder months.

Myth 2: Air Source Heating is Expensive to Install and Maintain

Fact: While the initial installation cost of an air source heat pump can be higher than that of a conventional gas boiler, the long-term savings and government incentives often make the investment more affordable. In fact, many households find that the cost of installing an ASHP becomes comparable to that of a traditional system when factoring in energy savings and available grants.

Air source heat pumps are also low maintenance, requiring only an annual service. With their longer lifespan compared to traditional boilers, they provide lasting value and reduce the overall cost of home heating in the long run.

Myth 3: Air Source Heating Requires Major Modifications to Your Home

Fact: Many homeowners are concerned that installing an air source heat pump will involve significant disruption or costly home modifications. However, the installation process is relatively simple. At Custom Renewables, it is important to us minimise disruption to your home wherever possible. In most cases, the outdoor unit of the heat pump requires only a clear space with good airflow. The indoor unit can be integrated into your existing heating system with minimal adjustments to pipes and fittings.

Myth 4: Air Source Heating Systems are Noisy and Unsightly

Fact: Earlier models of air source heat pumps were often associated with noise, but this is no longer the case. Modern ASHPs operate at noise levels similar to a refrigerator, making them suitable for most residential environments. The outdoor units are compact and can be discreetly placed in your garden or on the exterior of your home.

Thanks to technological advancements, planning restrictions on air source heat pumps have been relaxed. In most cases, the noise level is no longer an issue. This means the outdoor unit can be installed closer to the boundary of your property without causing any noise disturbance.

Myth 5: Air Source Heating Isn’t as Reliable as Traditional Heating Systems

Fact: Air source heat pumps are reliable, robust systems built to perform year after year. With minimal maintenance and longer lifespans than traditional boilers, ASHPs are designed for longevity. Furthermore, because they operate using electricity rather than gas, they are not subject to the same risks of fuel shortages or leaks. This ensures consistent performance year-round.

6 easy ways to make your home more energy efficient

As energy costs continue to rise, many homeowners in the UK are looking for ways to make their home more energy efficient & reduce consumption without sacrificing comfort. Thankfully, there are several effective, straightforward strategies to make your home more energy efficient, save money, and contribute to a healthier environment. Here’s how you can start making a difference today.

1. Take Advantage of Smart Home Technology

One of the easiest and most effective ways to cut energy use is by incorporating smart home technology. Devices like smart thermostats and smart lighting systems are designed to adapt to your lifestyle, ensuring that energy is only used when necessary. A smart thermostat, for example, can lower the temperature when you’re not at home or adjust based on your schedule, keeping your home comfortable without wasting energy. Similarly, smart lights can automatically turn off when you leave a room, preventing electricity waste.

By setting up a smart system that learns your routine, you’ll be able to manage your energy usage more efficiently, which can lead to significant savings over time.

2. Invest in Energy-Efficient Appliances

Upgrading to Energy Star-rated appliances is another great way to reduce your energy consumption. These high-efficiency appliances use less power while still delivering the same high performance you need. Whether it’s your fridge, washing machine, or dishwasher, choosing energy-efficient options means you’re using less electricity, which lowers your monthly bills.

By replacing older appliances with modern, energy-efficient models, you’re making a smart investment that will pay off in long-term savings and help reduce your household’s carbon footprint.

3. Seal Drafts and Insulate Your Home

Good insulation is key to making your home more energy efficient. Heat loss through gaps and poorly insulated walls can cause your heating system to work overtime, driving up your energy bills. Simple upgrades like sealing draughts around windows and doors and adding insulation in your loft and walls can make a significant difference. Proper insulation helps to keep your home warm during the winter and cool during the summer, reducing the need for constant heating or air conditioning.

This easy-to-do improvement will help retain the warmth in winter and keep your home cooler in summer, making your space more comfortable year-round while cutting down on energy use.

4. Utilise Natural Heating and Cooling

Make the most of natural resources to reduce your reliance on heating and cooling systems. During the winter, let the sun warm your home by opening curtains or blinds to allow natural light to flood your living spaces. On sunny days, this can help maintain a comfortable temperature without having to turn on the heating.

In the warmer months, use strategic landscaping or shading techniques, such as planting trees or installing shading devices, to keep your home cool and protect it from the sun’s heat. These natural cooling methods can reduce the need for air conditioning, making your home more energy efficient and saving money.

5. Adopt Simple Energy-Saving Habits

Sometimes, small changes can make the biggest impact. By adopting a few energy-saving habits, you can significantly reduce your overall energy consumption. Turn off lights when you leave a room, unplug devices that aren’t in use, and opt for energy-efficient LED light bulbs, which use far less electricity than traditional bulbs.

Additionally, consider air-drying clothes instead of using a tumble dryer, and reduce your washing machine’s temperature for smaller loads. These small changes may seem insignificant, but they add up over time and make a noticeable difference in your energy bills.

6. Explore Renewable Energy Options

For a more long-term solution, consider investing in renewable energy sources like solar panels or heat pumps. Solar panels harness energy from the sun, while heat pumps extract heat from the ground or air to heat your home. These renewable options can greatly reduce your reliance on the national grid, leading to lower energy costs and a more sustainable home.

Though the initial installation cost can be significant, renewable energy systems often pay for themselves over time through reduced utility bills and potential incentives from government schemes.

Conclusion

Boosting your home’s energy efficiency doesn’t have to be difficult or expensive. Whether it’s using smart technology, upgrading to energy-efficient appliances, or making simple changes to your habits, there are plenty of ways to reduce your energy consumption and save money.

What are the benefits of solar panels?

In recent years, solar energy has become one of the most popular and reliable renewable energy sources worldwide. With an increasing awareness of the environmental and financial advantages of using solar power, more homeowners are making the switch to solar panels. But what exactly are the benefits of installing solar panels on your property? Let’s explore the key reasons why adopting solar energy could be a smart choice for you and the planet.

1. Lower Your Electricity Bills

One of the most appealing benefits of solar panels is the reduction in electricity costs. Solar energy harnesses the power of sunlight, which is free, abundant, and renewable. Once you’ve covered the initial installation cost of the solar system, you will see a significant drop in your electricity bills. This is because solar panels generate their own electricity, reducing or even eliminating your reliance on the grid.

Over time, the savings can add up significantly, especially as energy prices continue to rise. Many homeowners report that their solar systems cover a large percentage of their energy needs. In some cases even providing enough electricity to power their entire home.

2. Reduce Your Carbon Footprint

Solar panels are a clean and sustainable energy source. Unlike fossil fuels, which emit harmful pollutants when burned, solar power is a completely renewable resource. By switching to solar energy, you are significantly lowering your carbon footprint.

A typical solar panel system on a home in the UK can save around one tonne of carbon dioxide emissions per year. While this figure may vary depending on the size of the system and the region, it’s still an impactful contribution to the fight against climate change. To put it into perspective, that’s the same as driving 3,600 miles – or making the round trip from London to Bristol 30 times.

By investing in solar panels, you are not only saving money but also contributing to a cleaner, healthier environment. This long-term commitment to sustainability helps reduce global greenhouse gas emissions, supporting the transition toward a carbon-neutral future.

3. Earn Money by Selling Excess Energy

One of the lesser-known benefits of solar panels is the ability to sell excess electricity back to the grid. If your solar system produces more electricity than your household needs, you can export the surplus energy and get paid for it. This is made possible through the Smart Export Guarantee (SEG). The SEG is a government program that allows homeowners with solar panels to earn money by selling electricity they don’t use.

This can be a great way to offset the cost of your solar system installation. The rate at which you are paid for the energy you export can vary depending on your energy supplier and the terms of your contract. It is always a good idea to shop around for the best deal.

4. Increase Your Home’s Value

Installing solar panels can also increase the value of your property. Potential homebuyers are increasingly looking for eco-friendly features. Having a solar power system installed makes your home stand out in the real estate market. Not only does this improve your home’s sustainability credentials, but it can also save prospective buyers money on their future energy bills.

According to some studies, homes with solar panels can see a boost in resale value, with some estimates suggesting a return on investment of up to 4% more than comparable homes without solar installations.

5. Energy Independence and Reliability

Another significant benefit of solar panels is the increased energy independence they provide. By generating your own electricity, you are less reliant on the national grid. This is particularly beneficial during times of energy shortages or price hikes. For those living in rural or remote areas, solar panels can offer a more reliable source of electricity when the grid might be less dependable.

In addition, many homeowners choose to complement their solar systems with energy storage solutions, such as solar batteries. These allow you to store excess electricity generated during the day for use at night or during periods of high demand. This adds an extra layer of energy security and helps ensure that you can still rely on solar power even when the sun isn’t shining.

6. Take Advantage of Government Incentives and Schemes

Governments around the world, including the UK, offer various incentives and rebates for homeowners who choose to install solar panels. These financial incentives are designed to encourage the adoption of renewable energy, making it more affordable for people to switch to solar power.

In the UK, the Smart Export Guarantee (SEG) is one example of such an incentive, but other programs like low-interest loans and tax credits may also be available, depending on your location and the type of system you install.

Before proceeding with your installation, it’s always a good idea to check if there are any financial incentives or government programs that can help reduce your upfront costs or provide you with ongoing financial benefits.

7. Low Maintenance and Long Lifespan

Once your solar panels are installed, they require very little maintenance. Most solar systems are designed to last for 25 years or more, with minimal upkeep needed throughout their lifespan. Occasionally, cleaning your panels or having a professional inspection can help ensure they are operating efficiently. Beyond that, there’s not much you need to worry about.

The durability of solar panels also means they continue to generate energy for decades, offering long-term benefits both financially and environmentally.

Conclusion

In summary, the benefits of installing solar panels go far beyond just reducing your electricity bills. They help reduce your carbon footprint, provide an opportunity to earn money by selling excess electricity, and can even increase your home’s value. Plus, with government incentives, low maintenance requirements, and the potential for long-term energy independence, solar panels are a wise investment for homeowners looking to embrace a cleaner, greener future.

Whether you're motivated by cost savings, environmental concerns, or energy independence, solar panels offer a wide range of advantages. This makes them a smart choice for many homeowners.

Are heat pumps worth it?

You may be wondering whether a heat pump is worth it?

A heat pump will typically save you money over its lifetime, compared to a gas boiler. This means you can actually cut your costs by going green.

This is down to a combination of rising gas prices, the government’s Boiler Upgrade Scheme, the increasing efficiency of heat pumps, and the need to replace a boiler after 10 years – unlike an air source heat pump, which generally lasts 20 years.

Heat pumps will massively cut your carbon emissions, future-proof your house from future boiler bans, and provide you with a consistent year-round supply of heat.

Let’s look at each of these factors in turn.

Helping to navigate the changing cost of energy

Heat pumps are between 300% and 600% more efficient than gas boilers, but they’re powered by electricity, which currently costs four times more than gas in the UK.

However; it's important to note that heat pump owners can utilise renewable energy-specific tariffs that will have you paying less overall.

The future of energy pricing is hard to predict, so it’s worth comparing your monthly electricity bills currently to a renewable energy tariff and see what savings you can expect to make.

Available grants to help lower the cost

The Boiler Upgrade Scheme is the main heat pump scheme for those in England and Wales, offering £7,500 towards the cost of £7,500.

This can significantly lower the installation cost of heat pumps.

The application for the scheme is installer-led, with the installer applying for the grant on the property owner’s behalf.

A heat pump will help you stay ahead of any potential boiler ban

It is believed that the Boiler Upgrade Scheme was created with a view to ban gas boilers however the current government has vowed to scrap this in favour of financial incentives to install low-carbon technologies, like heat pumps.

Moving to a heat pump now helps you stay ahead should any ban come into place in the future.

The growing demand and increased efficiency

The popularity of the Boiler Upgrade Scheme highlights the growing demand for heat pumps.

In fact, according to the latest figures from the government, as of November 2024, the total figure of applications since it began in April 2022 is over 62,000.

Such a big demand carries the risk of manufacturers increasing prices.

However the positive effect of a thriving market is that manufacturers are able to constantly invest in technology meaning Heat pumps are becoming more and more efficient which would net you an even higher amount of energy bill savings over a machine’s lifetime.

Our final verdict: Is a heat pump worth the investment?

Heat pumps are incredibly efficient, can cool and heat your home, and can create energy from air, ground or water – three completely renewable resources.

Plus, the Boiler Upgrade Scheme means you can save money on final installation costs, helping reduce the overall cost. There’s little work for you to do, too, as we will apply on your behalf.

At Customer Renewables, we work closely with every client to discuss their individual requirements and make sure that a Heat pump is the right choice for their home.
