Having reliable access to hot water is essential in any home. While many households are familiar with combi boilers and traditional hot water cylinders, another option you may encounter when upgrading a heating and hot water system is an unvented cylinder.
Megaflo is one of the names commonly associated with this type of hot water system. However, before deciding whether an unvented cylinder is appropriate for your property, it is important to understand how the system works, what installation involves and why ongoing maintenance matters.
At Boiler Time, we specialise in unvented and Megaflo installation and maintenance alongside our wider boiler, heating and plumbing services. Slough is one of the areas we cover, allowing local homeowners to get professional support when considering changes to their heating and hot water systems.
Here is what you need to know.
What Is An Unvented Hot Water Cylinder?
An unvented cylinder is designed to store hot water for use around the home.
Unlike a traditional vented cylinder, an unvented system does not rely on a separate cold water storage tank in the loft. Instead, it is connected to the mains water supply.
The stored water can then be supplied to taps, showers and other outlets when required.
Whether this type of system is appropriate will depend on the individual property, including its water supply, available space and household hot water requirements.
This is why choosing a hot water system should involve more than simply selecting a particular cylinder. The complete setup needs to be considered.
Boiler Time provides professional heating system installation services tailored to individual homes, with advice available when selecting an appropriate system.
What Is A Megaflo?
Megaflo is a well-known type of unvented hot water cylinder.
You may therefore hear homeowners use the terms “Megaflo” and “unvented cylinder” interchangeably, although Megaflo refers to a particular product range rather than every unvented cylinder available.
At Boiler Time, Megaflo systems are specifically included within the unvented cylinder installation and maintenance services we provide.
If you are considering one for your Slough property, the important question is not simply whether a Megaflo sounds appealing. You need to establish whether an unvented system is suitable for the property and your household’s requirements.
How Is An Unvented Cylinder Different From A Combi Boiler?
One of the major differences is hot water storage.
A combi boiler generally heats water as it is required rather than storing a substantial quantity of hot water in a separate cylinder.
An unvented cylinder stores hot water ready for use.
This difference can make the two arrangements suitable for different types of homes and household requirements.
A property with several bathrooms and greater simultaneous hot water demand may have different requirements from a smaller home with one bathroom, for example.
That does not mean one system is universally better than the other.
The right option depends on the property, existing heating setup, mains water supply and how the household uses hot water.
If you are considering changing the wider heating system at the same time, Boiler Time’s boiler and heating installation service can help you consider an appropriate setup for your home.
Why Might Slough Homeowners Consider An Unvented Cylinder?
One reason homeowners explore unvented cylinders is their hot water requirements.
Modern households can place significant demands on hot water, particularly where several people need showers, baths and hot water from different outlets.
A correctly designed unvented system stores hot water so that it is ready when required.
Removing the need for a traditional cold water storage tank can also be useful in properties where homeowners want to reconsider how available space is being used.
However, every property is different.
Before deciding that an unvented cylinder is the answer, it is important to establish whether the property’s water supply and wider heating system are appropriate for the proposed installation.
Is Your Mains Water Supply Suitable?
This is an important consideration.
Because an unvented cylinder receives water directly from the mains supply, the characteristics of that supply matter to the performance of the system.
A professional installer can assess the property and determine whether the proposed setup is suitable rather than making assumptions based simply on the number of bathrooms or size of the home.
This is one of the reasons professional planning is essential.
Boiler Time specialises in central heating and hot water installations and provides advice on selecting systems according to the needs of the individual property.
What Size Cylinder Do You Need?
Choosing the appropriate cylinder capacity is another important part of the installation process.
A cylinder needs to suit the hot water demands of the household.
Installing something without considering how many people live in the property and how hot water is typically used could result in a system that does not suit the household’s requirements.
Factors that may need to be considered include the number of occupants, number of bathrooms, typical hot water use and available installation space.
Rather than simply choosing the largest cylinder possible, the aim should be to select a system appropriate for the property.
Where Can An Unvented Cylinder Be Installed?
The best location will depend on the layout of the home and the wider heating and plumbing arrangement.
One difference compared with older vented systems is that an unvented cylinder does not require the same traditional cold water storage tank arrangement in the loft.
However, that does not mean it can simply be placed anywhere.
The cylinder, associated pipework and necessary safety components all need to be installed correctly, with suitable provision for the system’s requirements.
If you are renovating your Slough home, considering the hot water system early in the project can make it easier to plan where equipment and pipework will be positioned.
Why Professional Installation Is Essential
Unvented cylinders are not a straightforward DIY plumbing project.
These systems operate with stored hot water under pressure and incorporate important safety controls. Installation therefore needs to comply with the relevant requirements and be completed by someone with the appropriate competence.
Professional installation also allows the wider heating and plumbing system to be considered.
At Boiler Time, our heating system installations are completed by qualified professionals, with the team handling setup, necessary connections and testing.
We also provide a 12-month guarantee on the work we complete, covering parts and labour.
What Does Installation Involve?
The exact installation process will depend on the property and whether an unvented cylinder is replacing an existing system or forming part of a larger heating upgrade.
Before work begins, the property and existing setup need to be assessed.
An installer can then consider where the cylinder should be located, how it will integrate with the wider system and what additional work may be required.
If you are also replacing a boiler, it makes sense to consider both parts of the heating and hot water system together.
Boiler Time’s installation service includes professional advice, setup, necessary connections and testing to ensure the completed system is operating correctly.
Can You Install A Megaflo While Replacing Your Boiler?
If you are already planning a significant heating upgrade, this can be a useful opportunity to consider your hot water arrangement as well.
Rather than automatically replacing each component with something identical, homeowners can look at how the household currently uses heating and hot water.
For example, if your family has grown or the property now has additional bathrooms, the demands placed on the system may be different from when the original boiler and cylinder were installed.
Boiler Time installs heating systems tailored to individual requirements and can provide professional advice when selecting the right boiler or heating system for your home.
Why Does An Unvented Cylinder Need Maintenance?
Installation is not the end of looking after a hot water system.
An unvented cylinder incorporates components designed to help it operate correctly and safely. These need appropriate ongoing attention.
Regular maintenance provides an opportunity for the system to be inspected and for potential problems to be identified before they develop further.
At Boiler Time, our services specifically include unvented and Megaflo maintenance as well as installation.
Keeping on top of maintenance can also make it easier to spot changes in performance rather than waiting until there is a complete loss of hot water or another obvious problem.
What Are The Signs That Your Cylinder Needs Attention?
Homeowners generally become familiar with how their hot water system behaves.
Changes in normal performance should therefore not simply be ignored.
If you experience a noticeable reduction in hot water performance, unusual noises, leaks or another change in the way the system operates, it is sensible to have it professionally checked.
There may be a relatively straightforward explanation, but diagnosing the problem properly is preferable to attempting to repair a pressurised hot water system yourself.
Boiler Time also provides heating system repair services covering a range of heating and plumbing problems.
Don’t Ignore Leaks
Water appearing around a cylinder or associated pipework should be investigated.
Not every leak has the same cause or severity, so it is important not to make assumptions about where the water is coming from.
If you notice a leak, arranging professional assessment can help identify the source and determine what work is required.
Boiler Time’s repair service covers issues ranging from minor leaks through to more significant heating system failures, with clear quotations provided before work begins.
What About Changes In Hot Water Pressure?
A noticeable change in hot water performance can also indicate that the system needs attention.
Because several factors can affect water flow and pressure within a property, a change does not automatically mean the cylinder itself is faulty.
The mains supply, valves, pipework and other parts of the system may all need to be considered.
A professional assessment allows the complete setup to be examined rather than replacing components unnecessarily.
Should You Maintain The Boiler At The Same Time?
If your unvented cylinder forms part of a wider boiler and central heating system, it is important not to forget about the other equipment.
Your boiler requires its own appropriate maintenance.
Boiler Time provides boiler and heating system servicing carried out by Gas Safe registered engineers. During servicing, our engineers carry out comprehensive checks, clean essential components and look for potential issues before they develop into more costly problems.
Keeping both the hot water and heating systems properly maintained can help you stay aware of their condition and address faults when they appear.
Is A Megaflo Suitable For Every Slough Home?
No single hot water solution will be right for every property.
A Megaflo or another unvented cylinder may be worth considering where stored hot water suits the needs of the household and the property is appropriate for an unvented system.
Other homes may be better suited to a different arrangement.
Before making the decision, consider your current hot water demand, number of bathrooms, existing heating system, available space and the characteristics of the mains water supply.
If you are carrying out a major refurbishment or changing your boiler, this is also an opportunity to assess the heating and hot water system as a whole.
Unvented Cylinders And Home Renovations
A renovation can be an ideal time to reassess your heating and hot water requirements.
If bathrooms are being added, rooms reconfigured or the existing heating system replaced, the hot water system may need to accommodate different demands.
Planning this early can also make it easier to determine where a cylinder and associated pipework should be positioned.
Rather than selecting heating and plumbing components separately, consider how they will work together once the renovation is complete.
Boiler Time provides a range of boiler, heating and plumbing services that can help when considering wider changes to a property.
What If Your Existing Cylinder Is Having Problems?
Problems with an existing hot water cylinder do not necessarily mean that the entire heating system needs replacing.
The first step is to establish what has gone wrong.
If a component can be safely repaired or maintained, that may be all that is required. If the existing cylinder is no longer appropriate or a wider system upgrade is already planned, replacement may be worth considering.
The important thing is to avoid guessing.
Boiler Time’s heating repair service provides professional diagnosis and repairs, while our installation service is available where a new heating or hot water system is required.
