Hot water system installation and replacement
Installing or replacing a hot water system requires skill and precision, as an incorrect setup can cause inefficiency, leaks, or frequent breakdowns. Our licensed plumbers assess your property’s requirements and provide a tailored solution, whether you’re upgrading an old system or installing a new one. With professional hot water system installation from Fluid, you get safe, efficient performance and long-term reliability.
Hot water repairs and maintenance
Experiencing leaks, fluctuating temperatures, or failing components can disrupt your hot water supply and drive up energy costs. Our licensed plumbers quickly diagnose issues and carry out hot water heater repair and ongoing hot water maintenance to prevent future breakdowns. Regular servicing ensures your system stays efficient and reliable, with long-term performance guaranteed by Fluid.
Electric, gas and instant hot water systems
Electric, gas, and instant systems are the most common in residential homes and are typically straightforward to assess when handled by an experienced plumber.
Our team works across all major system types, using accurate testing and proven fault-finding methods to identify worn parts, performance issues, or system failure and identify the root cause of the issue.
We specialise in diagnosing electrical, gas, and instant hot water systems quickly and correctly. Once the issue is identified, we explain whether a repair is suitable or if a replacement will provide better reliability and efficiency.
If you’re considering an upgrade such as switching from storage to solar or heat pump, we clearly outline your options so your system is restored properly and performs as it should long term.
Solar hot water systems
Solar hot water systems can significantly reduce energy costs, particularly in homes with good sun exposure and consistent usage. We take the time to assess how the system is operating as a whole before.
If you’re deciding whether to repair or upgrade, we clearly explain the cost, performance, and long-term considerations so you can choose with confidence.
Heat pump systems
Heat pump systems have a higher upfront cost, but for many households they can pay for themselves through lower energy bills over time. Because performance depends on correct sizing, placement, and usage, assessment is key. We help you understand expected savings, payback time, and whether a heat pump is the right long-term investment for your home.
24 hours - 'I wish I had replaced' Change of Mind Policy
If for any reason in the next 24 hours you want to change your mind. We will put the amount of money you have spent on repairs towards the replacement heater of your choice.
