Reliable Hot Water Cylinder Installation in Bournemouth & Poole
At Senior Heating Services, we provide professional hot water cylinder installation for homes and businesses across Bournemouth, Poole, and the surrounding areas. Our engineers supply and fit both vented and unvented systems, ensuring you have the right solution for your property’s hot water needs. Whether you’re upgrading an outdated tank or installing a new cylinder as part of a heating system, we guarantee safe and efficient installation.
Benefits Of A Heat Pump
Reliable Hot Water Supply
Cylinders store heated water, ensuring you always have hot water available when you need it.
Improved Water Pressure
Unvented cylinders can provide mains pressure hot water to multiple taps and showers at once.
Energy Efficiency
Modern cylinders are insulated to reduce heat loss, helping lower energy bills.
Flexible Options
Available in a range of sizes and configurations to suit different homes and usage demands.
Types of Hot Water Cylinder
Vented cylinders work with a cold water storage tank, usually located in the loft. Water is fed from the storage tank into the cylinder, where it is heated and then distributed to your taps. Because they rely on gravity, water pressure can be lower unless a pump is added. Vented cylinders are cost-effective, straightforward to install, and easy to maintain.
Key benefits:
- Reliable flow of hot water
- Can be paired with a pump for stronger water pressure
- Simple and affordable installation
- Low maintenance requirements
Unvented cylinders connect directly to the mains water supply, providing hot water at mains pressure throughout the home. They do not require a cold water storage tank in the loft, making them a good choice where space is limited. Modern unvented systems are sealed and use either an internal air bubble or an external expansion vessel to manage pressure safely.
Key benefits:
- High water pressure for multiple taps and showers
- Flexible installation options, no loft tank required
- Delivers hot water quickly and efficiently
- Saves space, ideal for modern homes
At Senior Heating Services, we supply and install both types of cylinders and can advise on the best option based on your home’s size, water usage, and budget.
Which is Right for My Home?
The best choice depends on your property and household needs. A vented cylinder is often suitable for older homes with existing loft tanks and simpler systems, offering an affordable solution. An unvented cylinder, on the other hand, is ideal for modern properties or busy households that demand high water pressure for multiple bathrooms and showers running at the same time.
At Senior Heating Services, we can assess your home and recommend the most efficient and practical option to ensure reliable hot water every day.

Everything you need to Know
A: A hot water cylinder is an insulated tank that stores heated water, ready for use at taps, showers, and baths. You need one if your home uses a system boiler or conventional boiler — these boiler types heat water and store it in a cylinder rather than providing it on demand. If you currently have a combi boiler, you don’t have a cylinder, as combis heat water instantly from the mains. Cylinders are ideal for larger homes with multiple bathrooms where simultaneous hot water demand is high. Senior Heating Services can advise on the right setup for your property during a free pre-installation assessment.
A: A vented cylinder relies on a cold water storage tank, typically in the loft, and uses gravity to feed water into the system making it simpler and cheaper to install, but producing lower water pressure unless a pump is added. An unvented cylinder connects directly to the mains water supply, delivering hot water at full mains pressure to every tap and shower without needing a loft tank. Unvented systems are better suited to modern homes with multiple bathrooms. Senior Heating Services installs both types and will recommend the most practical option based on your property’s layout, water pressure, and household demand.
A: Hot water cylinder installation in the Bournemouth and Poole area typically costs between £600 and £1,500, depending on the cylinder type, size, and complexity of the installation. Unvented cylinder installations tend to sit at the higher end due to the additional pipework, pressure vessel, and compliance requirements involved. Replacing a like-for-like vented cylinder is generally more straightforward and affordable. Senior Heating Services provides free, no-obligation quotes with fully transparent pricing and no hidden charges. Call 07900 930 999 to arrange your assessment.
A: A standard like-for-like hot water cylinder replacement typically takes between 3 and 6 hours and is completed in a single visit. A more complex installation — such as switching from a vented to an unvented system, or fitting a cylinder in a new location can take a full day, particularly if additional pipework or upgrades to pressure systems are required. Senior Heating Services will give you a clear time estimate before work begins, and our engineers aim to complete every installation with minimal disruption to your home.
A: Yes unvented hot water cylinders must be installed by an engineer who holds a specific G3 Unvented qualification, as required by Part G of the Building Regulations. This is a legal requirement in the UK. Unvented systems operate under mains pressure and include safety devices such as pressure relief valves and expansion vessels, which must be correctly installed and tested by a qualified professional. All Senior Heating Services engineers hold the necessary qualifications to install unvented cylinders safely and in full compliance with current Building Regulations.
A: A well-maintained hot water cylinder typically lasts between 20 and 25 years, though the lifespan varies depending on water quality, usage levels, and how regularly it has been serviced. Common signs that a cylinder needs replacing include discoloured or rusty hot water, visible leaks around the tank, inconsistent water temperature, or a cylinder that is no longer heating water efficiently. If your cylinder is over 15 years old and showing any of these symptoms, Senior Heating Services can assess it and advise on whether repair or full replacement is the more cost-effective option.
A: Yes a hot water cylinder can be heated independently using an electric immersion heater, which works like a large kettle element inside the tank. This is useful as a backup when the boiler is out of service, or as the primary heat source in properties without a gas supply. However, electric immersion heating is generally more expensive to run than gas-heated systems, so it is best used as a secondary or emergency option. Senior Heating Services can install or replace immersion heaters as part of a cylinder installation or as a standalone job across Bournemouth, Poole, and Dorset.
A: Cylinder size is determined by the number of people in the household and the number of bathrooms. As a general guide, a 120-litre cylinder suits 1 to 2 people, a 150-litre cylinder is appropriate for a small family of 3 to 4, and a 200-litre or larger cylinder is recommended for households of 5 or more, or properties with multiple bathrooms and high simultaneous hot water demand. Choosing a cylinder that is too small results in running out of hot water during peak use. Senior Heating Services assesses your household’s usage patterns and recommends the correctly sized cylinder before any installation is carried out.
