Hot Water Systems Frequently Asked 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 free 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?

How often should you drain your hot water heater?

Refer to manufacturer standards on how often to release the PTR valve. If unsure, give me a call to walk you through it.

Is it bad to turn your hot water heater all the way up?

You shouldn’t adjust the thermostat as there is live power adjacent if unsure don’t proceed without engaging professional advice.

Can a water heater be installed directly on the floor?

Each tank is different and is installed according to Australian standards and manufacturers standards.

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 no-obligation quote is supplied with no call out fee so you can feel at ease to make a decision on a quality plumbing company here on the Sunshine Coast.

The brand of hot water unit that we use depends on the above variables. Some hot water units are better for low flow smaller pipes, whilst other brands are suited to a higher flow rate. All these factors are considered on-site with our free quote.

Does a plumber or electrician install a hot water heater?

A licensed plumber must install and certify the installation of a hot water unit. Refined Plumbing also holds a restricted electrical licence and as such can disconnect and reconnect an electric hot water unit. One call and one trade to sort all your hot water needs.
