Gas Hot Water Systems

Gas hot water systems use gas to heat water. The amount of gas used in the system is defined by the volume of water that needs to be heated. Gas hot water systems are ideal for households that have high energy bills as they are more efficient than electric hot water systems. Using hot water is one of the biggest uses of energy in the home. Taking advantage of an energy efficient new gas hot water system can save the household a significant amount of money.

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.

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

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.

What types of hot water systems are there?

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

What size water heater system should I buy?

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.

What are signs my hot water system needs a repair, replacement or service?

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.
