First time we used them and I was super impressed. Really friendly from the person who picks up the phone to person doing the job. For a job before Xmas I expected to take for ever was quoted and executed in 1 day. Price was reasonable and I would definitely use again.

Thanks, Carl, Josh, Franchesco and Alex for the awesome job! (Forgive me if I spell the names wrong) It is never a pleasant thing for any family to spend so much on pipe issues, but at least we are happy that we are always looked after by trustworthy professionals like you guys!

Frequently Asked

Gas Storage Hot Water Questions

An instantaneous hot water system, also known as a tankless or on-demand water heater, heats water directly as it flows through the unit. When hot water is required, cold water enters the heater, passes over a heating element (such as a gas burner or electric heating coil), and exits the unit as hot water. This provides instant access to hot water without the need for a storage tank.

Instantaneous hot water systems offer several advantages. They provide unlimited hot water on-demand, eliminating the need to wait for a storage tank to refill and reheat. These systems are more energy-efficient compared to traditional storage systems because they only heat water when needed, reducing standby heat loss. Additionally, tankless systems take up less space and typically have a longer lifespan.

Yes, instantaneous hot water systems can be suitable for large households. The key factor to consider is the system’s flow rate, which determines the volume of hot water the unit can produce per minute. By choosing a unit with a higher flow rate, you can ensure that multiple outlets can be used simultaneously without a significant drop in water temperature.

In many cases, it is possible to retrofit an instantaneous hot water system into an existing plumbing system. However, it may require some modifications to the plumbing layout and the installation of proper gas or electrical connections, depending on the type of unit chosen. It is recommended to consult with a professional plumber to assess the feasibility and requirements of retrofitting a tankless water heater.

Yes, like any other water heating system, instantaneous hot water systems require regular maintenance. It is important to flush the system periodically to remove mineral deposits that can accumulate and affect its efficiency. Additionally, it is recommended to have the unit inspected by a qualified technician annually to ensure proper operation and address any potential issues.
