Hot Water Systems Common Questions

How long does it take to heat a 250 Litre hot water system?

The general rule of thumb is 1 hour for every 100 Litres of water. So if your system isn’t hot in 2.5 hours for a 250 Litre it would be wise to contact Refined Plumbing.

What temperature should a hot water system be set at?

Your Hot water tank should be set at a minimum of 60 degrees celsius to prevent bacteria growth in the tank. It is a requirement that a tempering valve be installed to ensure the safe delivery of hot water is reduced at a maximum of 50 degrees to your common household.

Why is my hot water system not working – common problems

There could be a multitude of reasons why your hot water system isn’t working:

  1. First off establish the type of hot water system you have, Gas, electric, solar, heat pump.
  2. Second, once you have established the type of unit you have you need to identify where the problem is. Is the hot water unit itself hot but the water in your taps not? The answer to this question will lead you to whether the supply to the tank is faulty (Gas, electrical, solar) or whether the problem lies downstream of your tank (tempering valve or pipework).

Is it cheaper to leave the hot water on constant?

Keeping your hot water unit on will prevent bacteria growth in your water supply. However, if you are concerned about the amount of power the hot water unit is using there may be some tips and tricks to offer. Contact Refined Plumbing to book a safety check on your hot water system.

What are the signs your hot water heater is starting to fail?

Is your hot water unit taking longer to get hot? Is the amount of hot water you have less? Is your unit rusty or leaking? These are all signs you need immediate assistance from our fully qualified plumbers.

What is the most efficient hot water system? Cost? Brand?

To me, the most efficient hot water system is assessed on a case-by-case basis. I do full assessments and walk through with my clients to look at some variables such as:

-Access to pipework (Plumbing and Power)

-Access to drainage

-Clients desired outcome


Together with all this information, I can empower you to make a decision to supply hot water to your most valuable asset, your family home!

A fixed quote is supplied so you can feel at ease to make a decision on a quality plumbing company here on the Sunshine Coast.
