Instant Hot Water Systems

Instantaneous heaters operate by heating water on demand. They enable you to have a continuous flow of hot water because there is no storage tank, meaning your hot water supply won’t run out! The size of these instantaneous hot water systems is quite small in comparison to storage heaters, which allows them to be installed in places with limited space.

Instant Hot Water Systems

If you are looking for an efficient way to heat your water and need a system that provides a reliable supply, you should consider a hot water system that is based on a continuous flow. Unlike traditional storage hot water systems that can only heat a certain amount of water at one time, continuous flow hot water systems will never run out, unless of course you run out of gas to heat it! Instant hot water systems also don’t need to keep water heated when it is not in use; this makes the much more energy efficient saving you money on your bills. Instant hot water systems also take up much less space when compared to storage hot water systems.

If you’re looking for instant hot water systems, you’re in the right place. We’ve got a great range of instant hot water systems for you to choose from. We also have an installation service that will ensure that the installation is done correctly by a licensed plumber. Our locally owned and operated business has been providing fast, friendly and reliable hot water for years. Over this time we’ve created a reputation for excellence with 4000+ 5 star reviews.

I hired Service Today as I have used them in the past to replace my HWS which they did the same day as I had reported it broken down. They are very efficient. In this instance I needed a wall mounted TV installed on my Pool patio wall. After quoting within the hour of my call we arranged an install date of today which they honoured and I am very happy with the result. Job No.373071

The electricians Fuad and Chris were very knowledge and did a thorough job. Both were extremely polite and courteous ringing me to let me know their estimated arrival time and keeping me informed of what they were doing to fix my problem. I would definitely recommend this service. Highly efficient and thorough.

Service Today also services air conditioners. Ours had not been serviced for many years and wasn't working very well. The serviceman was careful to cover the furniture below the air conditioner and was efficient and thorough. The air con is working much more efficiently now.

FAQs

Why is my hot water a funny colour?

Sometimes when a water heater gets old, it starts to rust from the inside. If you have noticed that your hot water is no longer clear, we recommend you call Service Today and have your hot water system inspected – before it becomes a much bigger problem.

Hot water systems come in various heating options including electric, solar, gas and electric heat pump.

There are various considerations you should make when selecting the hot water system to suit your needs such as:

  • How many people live in your home?

  • How much hot water does your household use and when during the day?

Getting the right hot water system to suit your needs is important, if your storage heater is too small you potentially will run out of water and will have to wait. However, on the other hand, if your storage system is too big for your requirements, the system will need to maintain the water’s temperature even when not in use, costing you a pretty penny. Never fear though, Service Today can help you select the right hot water system for your needs.

There are many signs that can indicate that your hot water system requires a replacement, repair or service, these include:

  • Any type of rust or sediment in your water.

  • Fluctuating water temperature.

  • A leak around your hot water system.

  • When the pilot light goes out too often or is not working at all.

  • Low or fluctuating water pressure.

  • Hot water runs out often.

  • Unusual banging or not normal sounds coming from your hot water system.

  • You have no hot water available.

If you are experiencing any of these issues contact our friendly team, so we can get you back into those cosy warm showers as soon as possible.
