Frequently Asked Questions

1.What is a gas heating hot water cylinder and what makes gas hot water different?

Our gas heated hot water cylinders are different from regular hot water cylinders as they don’t actually require a large cylinder, or a cylinder-shaped anything – for that matter. Traditional hot water tanks are large and stored away someplace in your home, usually in a cupboard or kitchen space, gradually heating water for you to use. Gas water heating tanks are differentiated by their main heating power source being gas, as opposed to electricity or solar, and their tanks are usually more compact and rectangular in shape. Gas hot water cylinders (or califont tanks) are popular for large households due to their capability to generate large quantities of hot water quickly and efficiently. This means that your property can get more more reliable hot water for multiple showers, baths, and general day to day use for any size household. Being a smaller heating unit, these gas hot water cylinders are easier on the eye and even can be installed externally so you never have to see them at all and they don’t have to compete for storage space inside your home. Gas hot water cylinders installation often cost less to run than traditional electric cylinders, so are a popular choice for modern households in New Zealand.

2.So, how does a gas hot cylinder work exactly?

When you want hot water for a shower or washing up, you turn on the applicable tap. Cold water is then fed into the smaller style gas cylinder by pipes where a gas element immediately heats the water that runs through it, sending that new hot water straight to the tap or shower that is requesting it. It is an on-demand system, meaning that there is no hot water sitting in a tank waiting idle to be used, gas hot water is made instantly depending on the demand and can cope with large quantities when required. This can save on bills as your gas system won’t be continuously making hot water when it’s not needed and not being used. 

3.Gas Water Heater Control Panels

Gas hot water cylinders and systems have come a long way from where they started, You can now have a control panel installed in your home. These panels are suitable to control your gas heated hot water, adding a bit of smart luxury to your hot water experience. Different models of panels come with different features, including filling a bath at a set temperature (and the panel will even tell you when it’s ready!) This smart temperature setting is a safe way to always control your water without having to manually mix hot and cold temperatures from the taps. The setting of safe temperatures is house-wide so there will be no more worries about you or your little ones scalding yourselves during bath or shower time!

4.Cost-Effective Gas Hot Water Heating

There are many benefits to switching over to a gas-powered hot water system. There are no varying rates of gas during the day, unlike electricity, so no matter when you use it, it costs the same amount and doesn’t spike and give your bills a shock. The water is heated fast, so you don’t have to wait for your showers to warm up for ages which ultimately equals lots of wasted cold water poured down the drain.

5.How Much Does It Cost To Install a Water Heater With a Gas Cylinder?

While gas hot water installation prices vary depending on the kind of gas heating you choose, the model, and where in the house it is going to be installed. Costs are slightly different if replacing an existing model or cylinder, so it is best to get a comprehensive quote, no-obligation, from our team at the Hot Water Shop.
