As someone deeply committed to reducing my carbon footprint, replacing my gas boiler with a Daikin heat pump was a decision I made after careful consideration. Here are the key reasons behind my choice and my experience so far.

Reducing My Carbon Footprint

The environmental impact of a gas boiler became increasingly hard for me to accept. Knowing that every time I turned on the kitchen tap, even for just a few seconds of warm water, the boiler would ignite and burn gas was unsettling. This inefficiency weighed on me, prompting me to seek a more sustainable solution.

Fortunately, I already have solar panels installed, and I wanted to make the most of the energy they generate. A heat pump allows me to use solar energy to heat my home and water, creating a living environment that is not only comfortable but also sustainable. This alignment with my values made the switch an easy decision.

Cost Savings

One of the most significant benefits I’ve noticed is the substantial reduction in my energy bills. During the coldest months, my energy bills have decreased by 30%. For a home in a colder climate like Edinburgh, this represents a significant saving. Over time, the cost-effectiveness of the heat pump further validates my decision.

Improved Indoor Comfort

Living in Edinburgh, where the climate is cold and summers are mild at best, maintaining a consistently warm indoor environment is essential. Unlike a gas boiler, the heat pump ensures a steady and comfortable temperature throughout the year. The difference in comfort is remarkable, as my home now feels warm and inviting no matter how harsh the weather outside.

Reliable Hot Water Supply

Daikin supplied a 250-litre water tank as part of the installation, and its performance has been exceptional. With an optimised piping configuration, I tested the system with a 20-minute shower—not my usual routine but a deliberate test to push the limits. The heat pump maintained the water temperature perfectly, meaning there was no drop in temperature even after the shower. This ensures that multiple people can shower one after another without waiting for the tank to reheat.

Even with the heat pump set to stop heating the water, the 250-litre tank provides ample capacity for a bath, a shower, and kitchen cleaning. This flexibility and reliability have far exceeded my expectations.

The Importance of a Knowledgeable Installer

The installation was carried out by The Glasgow Heat Pump Company, and I cannot recommend them highly enough. Darren, the owner of the company, brought a wealth of expertise to the project. His meticulous planning and system design were instrumental in making the installation seamless and minimising disruption to my home’s interior.

Darren also helped debunk some of the misinformation I had received from other sources, providing clarity and confidence in the process. His attention to detail during the design and commissioning of the system ensured that everything worked perfectly. Without a doubt, Darren is the only technician I would wholeheartedly recommend to my family and friends. His professionalism and care have made this transition a genuinely positive experience.

Recently, Darren came back to upgrade several key radiators so they are intentionally oversized for the flow temperature my heat pump prefers. Moving to larger emitters means each room now reaches and maintains 23°C effortlessly, all while the system continues to sip the same amount of electricity. If you are planning a similar retrofit, don’t overlook emitter sizing—matching radiators to low-temperature heat pumps is one of the simplest ways to unlock extra comfort and efficiency.

Daikin recently published a case study about my Edinburgh installation, highlighting how the Glasgow Heat Pump Company helped me turn a new-build with a gas boiler into a blueprint for low-carbon living. They captured several details that resonate with this post:

  • Holistic sustainability – the Daikin Altherma monobloc, rooftop solar PV, and home battery now work together so effectively that even winter energy bills are often pennies, compared with the £120 per month I used to spend on gas.
  • Smart control – I rely on the Daikin Onecta app (and voice control) to monitor consumption and adjust the heating schedule remotely, something the case study calls out as a “game-changer”.
  • Practical support – the Scottish Government grant of £7,500 covered a significant portion of the installation, and I contributed roughly £7,000 myself. Darren handled the paperwork and integration, which Daikin emphasises as critical for homeowners who want to move quickly.

Final Thoughts

Switching from a gas boiler to a Daikin heat pump has been one of the best decisions I’ve made for my home. It’s not only reduced my carbon footprint but also lowered my energy bills and improved my quality of life. If you’re considering a similar change, I strongly encourage you to consult with The Glasgow Heat Pump Company. Darren and his team bring unparalleled expertise and a customer-first approach that you can trust.
