• Can I combine gas cooking, gas heating, and hot water on gas?

What Size LPG Hot Water System Do I Need?

Below is a summary of our Guide to LPG Hot Water System Sizing. Please see the full post for more information.

Firstly, work out the number of people in your household and the type of hot water system used, then ask yourself a few questions.

Below are the various LPG gas hot water system size guide factors:

• • Do they all take showers at the same general time of day?
  • Do they take showers simultaneously in different bathrooms?
  • Do the showers have WELS 3 Star Rated Water Saving Shower Head (maximum 9L/Min) or standard 18 to 25L/Min showerheads?
  • Do some prefer baths, which use more hot water? Is the bath or spa oversized, requiring even more hot water?
  • Do you run the washing machine, using hot or warm water, while people are showering?
  • Is your dishwasher connected to the cold or hot water? If hot, do you use it while hot water is being used elsewhere?
  • Do you live in a cold climate with cold incoming water?

Using a WELS 3-star rated water-saving shower head is a good idea. It will save water and energy whilst also reducing the size and cost of the LPG hot water system.

The LPG gas hot water heater size guide is best determined by counting the number of simultaneously used showerheads and whether or not you have a water saving shower head, as your LPG hot water system size guide.

The LPG gas hot water system size guide is best determined by counting the number of simultaneously used showerheads and whether or not you have a water saving shower head, as your hot water system size guide.

As an approximation of what size LPG hot water system do I need, you would want a 16L/min hot water heater for 2 water saving shower heads, 24L/min for 3 water saving shower heads and 32L/min for 4 water saving shower heads.

This LPG gas hot water system size guide is based on having 3 Star water saving shower head with continuous flow (instantaneous) LPG gas hot water heater and using all of the showers simultaneously.

With an instant LPG gas hot water system, the number of people doesn’t really matter, just the simultaneous use of the showers affects what size hot water system you need.

The use of other hot water taps, such as for a washing machine, will decrease the number of showers that can be used at the same time.

What are the Best LPG Hot Water System Prices?

Different types of hot water system have varying upfront costs and running costs, which are both important in determining the best water heater for you. 

A traditional electric water heater is cheaper to install than hot water on gas but the running costs are much higher than hot water on gas.

Typically, an LPG gas hot water system costs around $750 to $1,800, excluding installation and maintenance costs.

However, an LPG hot water system often has lower upfront costs than solar hot water systems and some can even supply hot water during power outages.

Gas is much cheaper to install than heat pump hot water, but for those on a higher budget heat pump hot water systems are available for about $2,300 to $4,000.

These systems use electricity to transfer heat from ambient air to the hot water heat exchanger instead of generating it directly.

Can I Combine Gas Cooking, Gas Heating, and Hot Water?

Homes and businesses have adequately sized gas cylinder to fuel multiple gas appliances and hot water on gas.

They would have a well-designed LPG system installed by a qualified gas fitter.

Combining gas appliances for cooking, room heating, and hot water is never a problem.

Energy Efficient LPG Gas Hot Water System – Star Ratings

The most energy-efficient LPG gas hot water system has a 6-star or even a 7-star energy rating.

With rising power costs, it makes sense to invest in efficient appliances that will save you money.

An instant LPG hot water system is generally the most energy efficient.

You also get to remove the cumbersome electric water cylinder to make more space for your home.

How to Look for Value Options

Every system has pros and cons, but an LPG gas hot water system offers many benefits over electric storage systems that will make your life easier.

For the best choice, make sure to factor in all the benefits of hot water on gas, including:

• Environmentally Friendly: An LPG gas hot water system heats water more efficiently. An instant LPG hot water system could be the right choice if you want to reduce waste and harmful emissions.
• Cost-Effective: LPG options include instant, continuous flow systems. Instead of storing hot water in a water heater tank, water is only heated when needed, bringing down energy costs.
• Saves On Space: Traditional water heating gas storage systems use bulky water tanks. An instant LPG hot water system, on the other hand, is tankless and small enough to be mounted on a wall.
• No Danger of a Leaking Cylinder: When using an instant LPG gas hot water system, there is no need for water storage in a large tank that can rust or leak.
• Cleaner Water: Fresh-flowing, instantaneous hot water is cleaner and healthier for you and your family. Hot water tanks can be a breeding ground for Legionnaires Disease bacteria.

Gas Boosted Solar Hot Water Systems

Solar hot water heaters have low running costs and few greenhouse gas emissions, but they are more expensive to purchase and install.

To provide hot water when there is insufficient or no sunlight, they are equipped with a booster unit.

Solar hot water system boosters can be electric, natural gas or LPG gas. 

It’s important to purchase gas-boosted solar hot water with enough solar panels and sufficient tank storage to reduce the risk of booster overuse.

Choose a gas-boosted solar hot water system that is compatible with your home’s roof configuration and check if you are eligible for solar hot water system installation rebates.

How an Instant LPG Hot Water System Works

The following is a summary of How an Instant LPG Hot Water System Works?

The instant LPG gas hot water system has been around for decades, but they still appear to be magical as they provide hot water on gas instantly without a visible power point or heating element. 

Here’s how a tankless water heater works.

• Cold water flows into the water heater when a hot water tap is opened.
• A sensor that detects the water follows ignites the gas burner using a heat exchanger to heat water.
• The water flows through the heat exchanger, absorbing as much heat as required.
• A control regulator unit modulates the gas burner to maintain a water temperature.

Your plumber will set your instant hot water system temperature to 50ºC to greatly reduce the risk of scalding without needing a tempering valve.
