“ I recently used Mr Splash Plumbing and would highly recommend them to every. The team that came to my house was very professional and respectful that I had a sleeping baby and ensured they were as quiet, quick and as clean as possible. Very happy with service and price. ”


“ Great and quick service. They came on time to fix my blocked drains and the problem was solved in no time, they also cleaned and left the places clean as if nothing happened. Their price was very reasonable.... ”

Rinnai Hot Water Systems

Every few home owners are aware whether their hot water system is working efficiently or not. As long as they get hot water in the tap, they don’t think of the amount of energy consumed to heat it. That’s because problems with the water heater aren’t immediately apparent. If your hot water system is old, it’s a good idea to inspect it and replace it. We at Mr. Splash Plumbing can help. If you’re in the market to buy a new water heater, we’d recommend you look into Rinnai hot water systems. They’re market leaders and have a strong customer service team.

Why Rinnai?

Rinnai is possibly the most popular and highly regarded manufacturer in the market today. This company has a global footprint and has seen incredible success everywhere. It doesn’t just offer hot water systems, but heating and cooling as well. The manufacturer’s products are often market leaders. The company offers a wide range of products that can be suitable for any kind of budget or need.

You just need to decide on a water heating system based on your consumption. You can consult with our experts if you’re not certain. They will help you figure out which product would be ideal for you. Rinnai hot water systems include the following:

  • Continuous Flow – Rinnai was the first company to introduce continuous flow hot water systems to Australia in the early 1990s. Before then, most people installed gas storage or electric storage systems. They weren’t as energy efficient and didn’t provide hot water on demand. Rinnai introduced the Infinity range, which still dominates the market. The modern Infinity hot water systems are awarded 6 energy star rating and are highly efficient.
  • Solar Hot Water Systems – Australia is a country blessed with abundance of sun. It’s a great idea to take advantage of that unlimited, inexhaustible source of power. Installing a solar hot water system would significantly lower your energy bills. Rinnai offers two different ranges of solar hot water systems. The Prestige range comes with stainless steel tanks, while the Sunmaster range has Vitreous Enamel steel tanks. Both of these ranges work well.
  • Storage Systems – Rinnai offers both electric and gas storage hot water systems. The gas system is more energy efficient with a 4 star rating. However, both ranges work well and will provide hot water whenever you need it. Storage systems have separate tanks to store hot water in. That means you’ll get hot water the moment you turn on the tap, if the tank contains some.
  • Heat Pump – Heat pump hot water systems are highly energy efficient. They take heat that’s present in the air and direct it towards the water to heat it.
