Compare dedicated water heaters and indirect storage. We’ll help you understand recovery, peak demand and the connections around the equipment.
Direct gas-fired commercial hot water
When hot water is essential to your working day, the replacement needs more thought than matching the old cylinder size. We can help plan an Andrews water-heater installation or look after the equipment already on site.

Indirect storage for suitable building demands
Need dependable hot water for staff facilities or a smaller commercial building? We can help assess whether a Gledhill cylinder suits the demand and how it should connect to the rest of the system.

Dedicated hot-water equipment and local project experience

Commercial calorifiers and water-heating arrangements
A commercial hot-water upgrade needs the storage and heat source to work together. We can help you review Hamworthy equipment and plan installation, replacement or maintenance around the building.

A cylinder’s size is only part of the answer. We’ll ask when showers, kitchens and washbasins are busiest, how quickly the system recovers and how far hot water has to travel. That helps us compare the right equipment without simply specifying a larger tank.
This Baxi commercial range brings gas-fired water heating and storage together. It is an option to assess where you need a dedicated hot-water appliance rather than relying entirely on the space-heating boilers.
For larger hot-water requirements, we can discuss this commercial water-heater range as part of a properly sized system. Distribution, storage arrangements and available plant space belong in the same conversation.
An indirect cylinder uses a coil supplied by the heating system. Gledhill’s range includes several storage sizes; we assess whether its recovery and capacity suit the particular premises rather than treat every cylinder as a high-demand commercial solution.

| Option | When to consider it | What we check |
|---|---|---|
| Dedicated gas-fired water heater | Hot water independent of the space-heating boiler | Peak demand, recovery, flue route and fuel supply |
| Indirect unvented cylinder | Stored hot water heated by a connected boiler | Coil duty, storage, incoming water and safety discharge |
| Multiple or bespoke cylinders | Sites needing a different storage or changeover arrangement | Space, redundancy, distribution losses and control strategy |
A useful first conversation
You do not need to know the answer before getting in touch.
Choose hot water and pressure supportA boarding house, changing room and office kitchen all use hot water differently. Tell us where your supply falls short and when it is busiest. We can help you look at the water heater, storage and connected pipework together.
At Burford Boarding School, the Oxyplumb Commercial team replaced a Lochinvar LPG water heater and hot-water return pump within a ten-day programme before pupils returned. You can see the work and equipment in the project photographs.
We can help you compare the options. How much hot water you use, how quickly it needs to recover, the available supply and the space all matter. Burford needed a commercial water heater, while the museum project used on-demand hot water. We will look at what suits your building.
