FAQ's

View all

What’s included in my installation?

We offer same-day or next-day service for urgent replacements. For standard installations, we’ll schedule a time that works best for you, usually within a few days.

Do I need to upgrade my tapware when moving to mains pressure?

Our standard installation includes supplying the new hot water cylinder, connecting it to existing plumbing, and removing the old cylinder. Any additional items like tempering valves or pipe upgrades will be discussed and quoted before installation begins.

How fast can you install?

Low-pressure systems are typically found in older homes, while mains-pressure cylinders offer better water flow and are common in modern installations. If you’re unsure, our team can help you decide based on your current system and household needs.

Do you remove my old cylinder?

Yes, we can relocate your hot water cylinder if required. This may involve additional costs for rerouting pipes, electrical work, or structural modifications, which we’ll quote before starting the job.
