This way we can come out to your place to get all the relevant information to provide you with an accurate quote for your job requirements, because we know no one likes extra costs added at the end of a job.

In our opinion you can't beat a Rinnai instantaneous gas hot water system. We find these units extremely reliable. There are also many benefits of an instantaneous system, the main benefit being that they provide hot water on demand. 

These units only heat the water as the water passes through so there is no need for a storage tank. This means you'll never run out of hot water (must have gas, power and water available). So you'll never have to fear a freezing shower again!

You will also free up space inside your home as the gas hot water units are placed on the exterior of your house giving you more room for storage or just to enjoy that extra space in your home.

Although gas installations are generally more expensive to install they are a great investment and when you have the right gas set up for your home you will save money. 

As mentioned earlier Rinnai units are our prefered gas hot water units as we find them extremely reliable however if its a Rheem unit you're after please do get in touch as we also install Rheem gas hot water units.

We have a price guide further below.

Rinnai A-Series

The Rinnai INFINITY A-Series are continuous flow hot water systems for residential applications. 

These water heaters produce endless hot water, and unlike electric cylinders, are energy efficient as they are only on when you need hot water.

There are five models to choose from depending on your hot water needs. Model numbers represent hot water capacity, for example the A26 produces 26 litres of hot water per minute at a 25 ° Celsius rise.

*6 Star Rating

*Efficient design - Multiple units can be manifolded together to make larger systems

*Space saving - located outside to give you more space inside

*Clever design - These systems modulate to heat water at lower flow rates

Rheem Gas Continuous Flow Units

Rheem Gas Continuous Flow Water Heaters deliver hot water when you need it, for as long as you need it, and they only heat water on demand. ( as long as you have gas, water and power available)

The appliance can be conveniently mounted to, or recessed into your exterior wall, giving you precious interior space back. 

*Flamesafe overheat protection 

*6 Star energy rating

*Digital display for easy fault diagnosis

*Frost protection

*Indoor and outdoor models

*Rheem Ez link - Compatible to link two units for increased supply

How much does it cost to switch over to a gas hot water system?

The cost for a hot water installation depends on a few different factors. Which brand of unit you choose, the size of the unit you need, how much pipe needs to be run and the complexity of the installation to name a few.

The location of the gas hot water unit also has to meet compliance so we need to check clearances and distances from windows, heat pump fans etc to see where your gas hot water unit can be placed. This is also a factor when it comes to pricing.

By coming out to get all this relevant information we can then provide you with an accurate quote for your job requirements because no one likes extra costs added at the end of the job.

Gas Hot Water Service

Gas is an affordable way to heat your water but like any other gas appliance it does need to be regularly serviced. Gas appliances need to be regularly checked to ensure that they are running safely, efficiently and performing at their best. Regular servicing will also ensure your not paying more for your gas then you should.

You do need to make sure that your gas hot water heater service is carried out by a registered gasfitter. At JVS Gasfitting we have years of experience in all things gas and are ready to service your unit and provide a gas safety certificate which you can provide to your insurance company if required. 


FROM $293.25 INC GST

Includes Gas Safety Certificate. Does not include any parts or materials if required. Price not final until confirmed.


Can't find what you need? no problem, get in touch and we will be more than happy to answer any questions.

Absolutely fantastic service and workmanship. Jason offers the rare trifecta of quality, price, and speed. We inherited a non-compliant installation after purchasing our house, so we were naturally worried about the cost and impact. Jason had the job done within half a day exactly to quote. He is obviously someone who takes great pride in his workmanship, which I appreciate as an engineer myself. Would highly recommend to anyone needing a job done!

Jason was fantastic from start to finish. Arrived right on time and straight into it! He was polite, knowledgeable, professional, tidy and respectful. We went from hot water cylinder to gas and Jason went above and beyond. Thank you for doing such great work.
