Hot Water Systems Frequently Asked Questions

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

General rule of thumb is 1 hour for every 100 Litres of water. So if your system isnt 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 house hold.

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 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.

Does a plumber or electrician install a hot water heater?

Tips to save power on your hot water system

Take Shorter Showers – Baths can consume loads of water so if the goal is to reduce the amount of hot water your household is using, it’s best to stick to short showers instead of baths.

Install Low Flow Shower Heads and Tap Fittings – these low flow devices are designed to produce a satisfying and powerful jet of water while reducing the amount of water being used.

Switch to a Front-Loading Washing Machine – top loading washing machines use a lot more water than a front loading machine.

Wash Full Loads in Your Dishwasher – wait until you have accumulated a full load before operating the dishwasher. You’ll use a lot less power and water this way.

Don’t Use Hot Water When Cold Will Do – do you really need to turn on the hot water tap or will cold do?

Reduce the Size of Your Hot Water System – Another way you can reduce your energy consumption when it comes to using hot water is to downsize your hot water system.

Dripping Taps Should Be Repaired – Dripping taps could be wasting electricity if the drip is coming from the hot water source.
