New Continuous Gas Systems

Professionally installed by qualified & licenced plumbers

Installing a continuous gas hot water system is a great way to benefit from cost-effective and energy-efficient hot water. Not only are they cheaper to run than an electric storage hot water system, but they also takes up less space and ensure that your family never runs out of hot water. These are some benefits of installing a continuous gas hot water system from Diploma Plumbing:

Low operating costs

By using gas instead of electricity, you can save up to 50% in operating costs over traditional electric storage tank water systems.

Instant hot water

You no longer have to wait for hot water with a continuous flow system, as the hot water is delivered on demand. This means that you can take a hot shower as soon as you turn on the tap.


Continuous gas systems are small, so they can be installed almost anywhere in your home and don’t require expensive installation work. You also have the option of varying the flow water rate.
