Professional Water Tank Installation in Bournemouth & Poole
Senior Heating Services provides reliable water tank installation for homes and businesses in Bournemouth and Poole. From replacing old or faulty tanks to fitting new systems as part of upgrades or extensions, our engineers ensure safe installation and long-lasting performance.
How A Water Tank Works
A water tank stores and supplies hot or cold water, helping your heating and plumbing system run efficiently. In many homes, tanks are used alongside boilers to ensure a steady supply of hot water, particularly in properties with multiple bathrooms or higher usage needs.
The system works by filling the tank from the mains supply and distributing water where needed. Hot water tanks are heated either directly through an immersion heater or indirectly via a boiler. Cold water tanks act as storage, maintaining consistent pressure and supply.
Correct installation is essential for safety, efficiency, and compliance with building regulations, which is why it should always be carried out by qualified engineers.
Benefits Of A Power Flushing
Reliable Hot Water Supply
A properly installed tank ensures a steady flow of hot water, even in homes with higher demand.
Improved Water Pressure
Tanks help maintain consistent pressure, reducing fluctuations during peak usage.
Long-Term Durability
Quality installation and correct sizing extend the lifespan of your system.
Tailored to Your Property
We install tanks that suit the specific requirements of your home, whether compact cylinders or larger capacity units.
What We Use
At Senior Heating Services, we understand that loft space can sometimes be limited, which is why we recommend water tanks designed to fit neatly through loft hatches. The tanks we install are supplied with Byelaw 30 kits, ensuring your water is protected against contamination from dust and insects.
If you have an outdated or unsafe tank, we can replace it with a modern alternative, keeping safety and reliability a priority. For restricted lofts, we offer long tanks (coffin tanks) or even dual smaller tanks where space is particularly tight.
Our tanks are supplied with:
- Snap-on lids for protection and ease of access
- Float-operated valves (4 ½”) for overflow and hot water vent pipes
- 22mm pipework connectors
- Part 2 ball valves (BS1212 standard)
- Angled service valves
Every installation is covered by a 12-month warranty for added peace of mind.
To achieve the best water pressure, we construct strong supporting frameworks and ensure tanks are installed at the correct height. Tanks are always mounted on a firm base and securely braced to hold maximum capacity without distortion.
All tanks are manufactured from durable polyethylene and are available in a wide range of sizes to suit your property and water system.

Everything you need to Know
A water softener removes the calcium and magnesium minerals that cause hard water, replacing them with sodium ions through a process called ion exchange. Hard water causes limescale build-up in pipes, boilers, and appliances, reducing their efficiency and lifespan. Senior Heating Services installs water softeners across Bournemouth, Poole, and Dorset areas where hard water is a well-documented issue helping protect your home’s plumbing and heating system long term.
Yes Bournemouth, Poole, and the wider Dorset area are classified as hard to very hard water regions. This means your water contains elevated levels of calcium and magnesium, which causes limescale accumulation in boilers, hot water cylinders, taps, and appliances over time. Installing a water softener protects your heating system, extends appliance life, and can reduce energy bills caused by limescale-coated heating elements. Senior Heating Services can assess your property and recommend the right unit.
A vented (open) water tank is fed by gravity from a cold water storage cistern, typically located in the loft, and relies on height for pressure. An unvented water tank is connected directly to the mains supply, delivering higher and more consistent pressure without needing a loft tank. Senior Heating Services installs both types and will advise which suits your property based on your water pressure, available space, and hot water demand across Bournemouth and Poole.
A standard cold water tank replacement or new loft tank installation typically takes between 2 to 4 hours for a straightforward job. Installing a new hot water cylinder or unvented system may take a full day, depending on pipework requirements and access. Senior Heating Services engineers carry out most water tank installations in a single visit, with all components including Byelaw 30 kits, ball valves, and pipework connectors supplied and fitted on the same day.
The cost of a water tank installation varies depending on the type of tank, its size, and the complexity of the installation. A basic cold water storage tank replacement generally starts from around £200–£400 including labour, while unvented hot water cylinder installations can range from £800 to £2,000 or more depending on the unit and access. Senior Heating Services provides free, no-obligation quotes with fully transparent pricing no hidden charges or call-out fees serving homes and businesses across Bournemouth and Poole.
Yes in a positive way. Softened water significantly reduces limescale build-up inside your boiler’s heat exchanger, pipes, and radiators, which is one of the most common causes of reduced efficiency and boiler breakdowns in hard water areas like Dorset. Pairing a water softener installation with a boiler service or power flush from Senior Heating Services gives your system maximum long-term protection and helps maintain manufacturer warranty compliance.
The right tank size depends on the number of occupants, bathrooms, and peak hot water demand in your property. As a general guide, a household of 1–3 people typically needs a 120–150 litre cylinder, while larger homes with 4+ people and multiple bathrooms may require 180–250 litres or more. For loft installations with limited access, Senior Heating Services can supply long-profile tanks (coffin tanks) or dual smaller tanks to fit through standard loft hatches without compromising capacity.
Yes water softeners require periodic top-ups of block or granular salt, typically every 4 to 8 weeks depending on household water usage and softener capacity. The resin bed should be checked annually, and the unit should be serviced every 1 to 2 years to ensure optimal performance. Senior Heating Services can advise on the right maintenance schedule for the unit installed and is available for ongoing servicing across Bournemouth, Poole, and the surrounding Dorset area.
