St Albans Based Unvented Cylinder Specialists

Many St Albans homes rely on unvented hot water cylinders to provide strong, reliable hot water for showers, taps, and multiple bathrooms. When properly installed and maintained, they can provide excellent hot water performance for busy households.

If your cylinder is ageing, leaking, losing pressure, or struggling to meet demand, replacing or upgrading the system can improve performance and reliability throughout your home. For wider hot water requirements, you can also explore our gas hot water system installation service.

We install, replace, and service unvented cylinders for properties of all sizes. Whether you’re upgrading an existing system or fitting a new cylinder as part of a renovation, we’ll recommend the most suitable option without overcomplicating things.

If your new cylinder is part of a wider heating upgrade, our central heating services can cover related heating work. We also provide bathroom installation services where hot water requirements form part of a larger bathroom project.

Understanding Unvented Cylinders: The Basics

An unvented hot water cylinder stores and delivers mains-pressure hot water throughout your home. Understanding how these systems work can help homeowners improve hot water performance, efficiency, and reliability.

Mains Pressure Hot Water: Provides strong, consistent water pressure to showers, baths, and taps without the need for a cold water storage tank.
Ideal For Larger Homes: Suitable for properties with multiple bathrooms and higher hot water demand.
Space Saving Design: Eliminates the need for loft tanks, freeing up valuable storage space within the property.
Energy Efficient Performance: Modern insulated cylinders help retain heat for longer and reduce energy waste.
Safety & Compliance Features: Equipped with specialist safety controls and pressure relief devices to ensure safe operation.

When Should You Replace or Upgrade an Unvented Cylinder Upgrade?

Not sure if your hot water cylinder is performing as it should? Here are some common signs homeowners experience before replacing or upgrading an unvented cylinder.

Reduced Hot Water Pressure

Weak showers or reduced water pressure from taps may indicate problems with the cylinder or associated components.

Insufficient Hot Water

Running out of hot water quickly or struggling to supply multiple bathrooms can be a sign that your cylinder no longer meets demand.

Leaks Or Corrosion

Visible water leaks, rust, or signs of corrosion around the cylinder should be inspected before more serious damage occurs.

Unusual Noises

Banging, humming, or rumbling noises from the cylinder can indicate internal wear, limescale build-up, or faulty components.

 Trustindex verifies that the original source of the review is Google. Really happy with the work carried out by Alban Plumbing and Heating. They fitted several new radiators in my home and the whole process was smooth from start to finish. They arrived on time, were friendly and professional, and took great care while working in the house.
The installation was completed to a high standard, everything was left clean and tidy, and the new radiators look fantastic and heat up perfectly. It's refreshing to find a company that is reliable, communicates well, and clearly takes pride in their work.
I wouldn't hesitate to use Alban Plumbing and Heating again and would happily recommend them to friends and family.

 Trustindex verifies that the original source of the review is Google. Asif has done a great job looking after our plumbing and heating for several years now. He also recently attended in under an hour to fix an emergency leak that he and his son sorted with great efficiency allowing us to get back to work and continue operating with minimal disruption to our business and patients. He’s reasonably priced and friendly and I’m sure we will be using him for many years to come.  His 5 star status is well deserved.
