Switching to gas hot water is an efficient choice for older homes and anyone planning a renovation should consider installing gas hot water systems.

Existing older home

  • Two bedrooms, older house undergoing a renovation
  • Two working adults, no dependents

Issue

Their existing electric hot water cylinder failed them during the re-insulation of the home they had owned for 20 years. 



With the hot water cylinder kaput, (the bottom rusted out entirely) and the old gravity-fed water pipes old and failing also, the Johnstons decided it was time to upgrade to gas hot water heating.

Action

The system was designed and installed to supply an adequate gas califont heating system and to be powered by two 45kg outdoor gas bottles.


They also replaced the three different kinds of water piping with new mains pressure pipes to improve volume and flow capabilities.


The entire switching process was easy, with the gas fitter taking care of every aspect from the supply, install, certification and consent.

It soon became apparent that the continuous flow, on-demand hot water system had bought tangible benefits, the client says.

Result

Since switching to gas hot water heating, the family have noticed:

  • Instant improvement in their water pressure and flow rate.
  • Showering is vastly improved and at a consistent temperature.
  • Space has been reclaimed since they no longer require interior space for a hot water cylinder.
  • Savings have been made on electricity use.

  • Seeking efficiencies in their new home operating costs

Issue

Knowing the benefits of gas hot water heating from having had it at previous properties, the client’s were resolutely certain that gas was the way to go.


“We had gas hot water in Akaroa for 17 years and coming up 11 years here and we’ve had absolutely no trouble with it,” 

Action

The Gas Fitter supplied and installed gas hot water heating, gas cooking hobs and gas-powered home heating to the family.



“We love using gas. It's easy, faster, cleaner and more cost-efficient. Yeah, we’re really happy,” They say.


Bottle swaps are dependable and scheduled and don’t need to be chased up.

Result

“We wouldn’t go back to electric hot water cylinders if you paid us to,” The Client says.  “If you are away from home for extended periods of time you can turn it off completely and start it up again when you return.” 


The fitters service was amazing, he says and the Rockgas deliveries prompt and reliable.

Rockgas Supplies to Twizel Holiday Home

  • Built a new family holiday home in Twizel

Action

Rockgas supplies the gas bottles to the Twizel holiday home. It’s reliable and scheduled.



“There’s mostly just the two of us there, but on occasion, there could be up to 10 people including babies and grandchildren,” The Client says.

Result

Having a continuous on-demand gas hot water system is a great fit for purpose says, the Client. “Because it's used periodically, having a hot water system you can turn on and off instantly and not have to think about draining water from unused cylinders in case of frosts is beneficial too,”.


Family Bach in Otematata

  • Retired couple mid 60’s with extended family & grandchildren
  • Aging electric hot water cylinder system in a family bach first built in 1957 and relocated from Roxburgh to Otematata in the 1960s.
  • Large 180-litre capacity but wasted economies keeping it heated when the bach unoccupied.

Issue

“It made sense to switch to gas hot water heating for the bach. We had switched to gas at our home in Oamaru already so we know how useful it is,” the client says.



The bach is used throughout the year at various times, hosting between 2 to 8 people at any one time.

Action

The Gas Fitter went out to Otematata and supplied & installed a gas hot water heating system for the family.



“It was pretty slick actually. They had it all in including the bottles in one day,” the client says.

Result

The Client is very happy with the switch to gas hot water and is also pleased that the bach reclaimed some space for a laundry since swapping out the cylinder for the gas califont system. “We wouldn't go back to electric now. Gas is beaut.”

Gas Conversion at Holiday Home in Glenavy

  • Two working adults mid 60’s
  • No dependents but extended family & grandchildren 
  • Converted a family holiday home to gas hot water heating in preparation for permanent living and hosting visiting family.

Issue

The existing old electric hot water cylinder at the Glenavy property was about to “burst its backside” says the client. “So we figured gas water heating would be the option for us. We intend to live there permanently in a couple of years and the home is a holiday destination for the family.”

Issue

Prior to moving into their new family home, the family had an electric hot water system and frequently found they ran out of hot water at peak times. The low-pressure electric cylinder lacked capacity and function for a busy household.

Action

Since moving to a home equipped with continuous on-demand gas hot water heating they have ended the bathroom struggle.



“Teenagers know how to use hot water, that's for sure, but we definitely notice the difference with gas. We never run out of water at any time and have better pressure and better showers,” the client says.


Choosing Autocheck with Rockgas has been handy for the busy family. They don’t need to remember to order a new gas bottle. Rockgas have them on a scheduled check & maintenance schedule.

“This ensures we never run out of gas. Rockgas calculate our usage throughout the year and turn up to swap our bottles out when they know it's near empty,” the client says.

A more harmonious household safe in the knowledge they won’t run out of hot water.  No battling for the first shower of the day and no paying for wasted heat as you would with an electric water heater.



“Also the fact you don't have to keep track of your own bottles because Rockgas has it sorted for you, is very reassuring,” the client says.



Existing older home with low water pressure

  • Two adults, one dependent

Issue

The Client accepted the Gas Fitters quote for supply and install of their new system. One that was a good price and included everything, he says.


The continuous flow gas hot water conversion for his bathroom was too easy. “The Gas Fitter took care of it all and had the system and the 2 x 45kg bottles in and running in no time,”

Although not keeping a running check on its efficiencies, he says the switch to gas hot water was definitely worthwhile.

We certainly noticed improved efficiencies. I calculated we saved about $300 a year in wasted heat from not having the water heater tank anymore.
