Additional Information on Air Source Heat Pumps

Heat Pump vs. Gas Boiler: Choosing the Right Option

When deciding between a heat pump and a gas boiler, understanding the key differences can help you make the best choice for your home and lifestyle. Heat pumps are an excellent option for eco-conscious homeowners, but factors like your property’s size and insulation quality are important to consider. Not sure which heating system is right for you? Read our in-depth Heat Pump vs Gas Boiler guide to help you make an informed choice on what’s best for your property. 

Air Source Heat Pump Regulations & Compliance 

Understanding air source heat pump regulations is essential for smooth installation and ongoing system performance. Here’s what you need to know: 

  • Planning permissions: Most properties are allowed one air source heat pump under permitted development rights, but specific planning permissions may vary by location. Always check your local requirements. 
  • Certification standards: All installations must comply with the Microgeneration Certification Scheme (MCS) to ensure high-quality workmanship and adherence to industry standards.  
  • Regular servicing: Routine servicing is vital for maintaining efficiency and safety and is also a key requirement for upholding your heat pump’s warranty. 

Navigating compliance can feel overwhelming, but our team is here to help simplify the process to ensure your installation meets all required standards.

Air Source Heat Pump FAQs

How does an air source heat pump work step by step?

These systems absorb heat from the outside air to warm your home and hot water, even in temperatures as low as -15 °C. They use electricity to power a cycle that heats a refrigerant, transforming it from liquid to gas, then compresses the warmth to heat your home. 

Are air source heat pumps worth it?

Yes! With an energy efficiency of over 350%, air source heat pumps are an excellent investment for eco-conscious homeowners looking to reduce energy bills and environmental impact.   

Why is my electric bill so high with an air source heat pump?

High electricity bills with an air source heat pump may result from incorrect settings, insufficient insulation or the system working harder in colder weather. Regular maintenance, like cleaning filters and ensuring proper refrigerant levels, is essential to keep it running efficiently. If the issue persists, Metro Plumb engineers can inspect your system to identify and resolve any problems.  

What is the downside of the air source heat pump?

While air source heat pumps offer many benefits, some potential downsides include reduced efficiency in very cold weather and higher upfront installation costs compared to traditional systems. However, the long-term energy savings, reduced carbon footprint and reliable performance make them a worthwhile investment for many homeowners.   

Do you need a cold-water tank with an air source heat pump?

Not all air source heat pump systems need a cold-water tank. If you opt for a system providing hot water for your home, a hot water cylinder is usually required to store the heated water. However, modern setups can vary. Our skilled engineers can assess your property and advise whether a cold-water tank or an alternative solution is needed.  

Do air source heat pumps work in winter?

Air source heat pumps are designed to work efficiently, even in winter. They extract heat from the outside air to warm your home and water, even when temperatures drop below freezing.  

Do I still need a boiler with an air source heat pump?

Air source heat pumps are designed to work independently, providing heating and hot water for your property. However, in some cases, a boiler may be used alongside the heat pump as part of a hybrid system to meet higher heating demands or for faster water heating.   

How much does an air source heat pump cost?

The cost of a heat pump may vary, but there are grants and financial incentives available to support installation. For instance, schemes like the Boiler Upgrade Scheme in the UK provide an air source heat pump grant to help reduce upfront costs. These incentives make it more affordable to switch to energy-efficient heating.

Exceptional and selfless service! Kyle went above and beyond to help us during a tricky situation! Unbeknownst to us we had a damaged a pipe for years leading to a bedroom radiator, yoday ehile having some decorating done it was found and while waiting for the council to send someone to help, Kyle, who was working nearby, stepped in. He wasn’t obligated to assist as he wasn’t assigned to us, yet he kindly fixed the issue on the spot. His professionalism and empathy were outstanding, and he saved us a lot of stress. An absolute credit to his team! Please give him a payrise or promotion!!!!! He is an absolute asset to your team!!!!!! Kyle, thank you so much! If the world was made up of more people like you, it'd be a much nicer place to live!!!! Thank you!

We had a sudden loss of water into our house. Our usual plumbers had no idea what was happening. The water supply company said it was our problem. Metro Plumbing came three times and worked out that it wasn’t a dropped valve or anything and did blowback 7 times And eventually managed to Dislodge a 4 foot section of matted Tree root from inside our Water Main! There were sudden restoration of cold water through the mains pipe into the house. Honestly, without them, we would be stuck without water! They were all very pleasant and courteous and listened to the complex Story of all the previous investigations. We now need to work out where the Tree root got into the Main water supply, but that’s another matter! They came three times and spent many many hours so the price I paid in fact was incredibly reasonable
