Top Hot Water System Installation & Repair related questions
No need to provide tools or equipment. Your Tasker will arrive with everything needed for the job. As for the cylinder, it’s up to your agreement with your hired plumber whether you’ll provide it or they’ll source it for you. Make sure you’ve discussed this prior to the actual installation day.
The installation process, from the area inspection to the installation itself, can run between one to three days. If there’s no underlying issue to address, it could be completed within a single day.
Yes! If you run a business and have more jobs than you can handle, feel free to hire Taskers to assist you. Discuss the scope of work and the skills you need when posting a task. That way, it’s easier to match with suitable experts.
Installing a hot water system yourself isn’t ideal. This type of job involves compliance with UK building regulations and safety requirements and requires proper certification. Unless you’re a certified plumber or specialist, you may be better off booking a qualified expert through Airtasker instead.
The size of the system you need depends on the number of people in your household, plus how much they use hot water. A good rule to follow is to allow for 30–40 litres of hot water per person for a gas system or 55–60 litres for an electric system. Consult your hired plumber for an accurate recommendation.
You may still have hot water for a short period. Typically, in a power cut, the water will remain warm for one to two hours. But this largely depends on your usage, as well as the temperature outside.

What do hot water system installation services include?
A complete hot water system installation service covers everything required to set up a safe, reliable system in your home. This service includes the following steps:
Inspecting the area
The installation begins with a detailed assessment of the chosen spot for your tank and its components. The plumber will ensure the area can support the cylinder’s weight and meets all local building regulations. If the space is inadequate, they can help you find a suitable alternative location for the system.
Preparing for the hot water system installation
Once the location is confirmed, your plumber will prepare for the installation of the hot water tank. If needed, they may create a reinforced platform to support the weight of the tank. You can also hire a carpenter to work on this separately to lessen your plumber’s load.
Before proceeding with the installation, your Tasker will shut off the water, gas, or electricity, as necessary. They will then measure the area and cut pipes or wires to the right sizes. They may also have to cut holes into walls or floors for the pipework.
Installing the cylinder
When preparations are done, your plumber will set the cylinder or tank in its designated position. They’ll carefully avoid damaging any components or nearby pipes during this stage.
Fitting the components
Once the cylinder is installed, your Tasker will attach pipes, wires, and important components like the Temperature and Pressure Release valve, expansion vessel, and immersion heater. You can expect them to strictly follow UK regulations and best practices to ensure the system is safe and fit for long-term use.
Testing the system
After the installation of the hot water tank, your plumber will test the entire system. This is to check whether hot water flows smoothly and at the correct pressure through all taps and showers. Any issues with temperature or pressure will be addressed right away. This process will be repeated until the system works without fault.Â
With your hot water now sorted, why not consider making your home an even more comfortable place to live in? Insulation installers are also available on Airtasker to help you achieve year-round warmth while lowering those energy bills.

Issue: Intermittent Hot Water Failure - Heatrae Sadia PremierPlus Unvented Cylinder I have a Heatrae Sadia PremierPlus unvented electric hot water cylinder with an external Aquasystem expansion vessel. The issue is intermittent: * Sometimes there is no hot water at all. * The system occasionally starts working again by itself. * Sometimes I can get it working by turning the electricity off and on or repeatedly using the Boost function. * When it starts working again, it can take several hours before hot water is available. * No obvious leaks are present. * The expansion vessel appears intact, but I am unsure if it is related.
We’ve received an excellent service from Egzon. He was very quick to spot the issue and organize the fix for it. Highly recommend.
