Heavy Duty Hot Water System Cost Saving. How?

Are there other options to reduce your cost on installing expensive hot water systems every 6-8 years at a cost of between $7000-9000 each time.  We have some great ways for you to reduce your hot water running costs and at the same time reduce your replacement costs as the years go by. In some cases reducing ongoing maintenance cost by up to 40%. Lets say you have multiple heavy duty hot water systems in a bank or row that are manifolded or connected together replacing one system every 6-8 years can really add up and deplete the Strata funds.

Call us out the next time your system fails.  Keep in mind that if you have a Rheem 275l heavy duty then you have a great system already but you can make your money go further.

Rinnai Gas Hot Water Mains Pressure Tank System Addon. Booster or Supercharger

Rinnai Infinity Domestic or Commercial Gas Mains Pressure Hot Water System Tank Addition

Turn your Rinnai B26 or Infinity 26 which is a 15 litre per minute hot water system at 50-55 degrees into a FULL FLOW – Mains Pressure 780 Litres in the first hour*  mains pressure hot water system that can supply hot water to as many taps as you wish based on the storage tank size you select and your current pipe sizing. This is close to a Rheem Heavy Duty 275 Litre and the Rinnai Demand Duo Commercial Hot Water Systems costing around $6900 just for the hot water unit.

*(small 50 litre storage tank. 80 litre extra $200, 125 litre tank extra $400. Larger tank options and Multiple Rinnai Infinity 26 connected together for larger hot water requirements) Case Study below.

Hot Water System Tank Addition

This system addon is only $1990 Incl GST Installed and Supplied.

Tank recovery 3.5 minutes.

System is made up with a Rinnai/ Rheem Storage Tank and a Grundfos or Davey Hot Water Circulating Pump. Manifold is suit the individual installation

A Rinnai 26 or Builders B 26 can support 2 showers at the same time.  They increase the water temperature 20 degrees at a rate of 26 litres per minute. They need to reduce the water flow so they can produce 50-60 degree temperatures at the tap.  The reduced flow rate is dependent on the cold water supply temperature.  If the cold water temperature is 15 degrees at a 26 litre per minute flow rate the water will be only 35-40 degrees(20-25 degree increase at 26 litres per minute).  The Rinnai 26 or b26 reduces the flow rate down to say about 15-18 litres per minute so as to achieve the desired temperature of 50-60 degrees.

Where the Rinnai Mains Pressure Tank System comes into it’s own is that the same flow rate and pressure you get from the cold water tap you will have with the hot water tap also.  The beauty here is that the Rinnai heats up the water in the tank at a very rapid rate and at a excellent 6.1 energy rating.


Say you have a small holding or hot water storage tank of 50 litres set at 53 degrees.  4 showers running using 9 litres per minute or 24 litres per minute at 40 degrees at the shower. Cold water temperature of 15 degrees and a Rinnai flow rate at a set 53 degrees at the tank but 50 degrees at the tap outlet(heat loss). One Rinnai 26 or Builders B26 supporting the small 50 litre tank will last for 9 minute with the taps running constantly. It will hold above 40 degrees for 30 minutes. It will also fully recover in 3.5 minutes to 53 degrees or in 16 minutes with only 2 showers being used.

Case Study.

We installed this system in Manly which has 21 one bedroom apartments. 21 Kitchens and bathrooms. The tank size is 250 litres and only one Rinnai 26 needed. They wanted a second Rinnai Infinity 26 installed only as a back up.  This system has been working with out a problem for 5 years now.

Example Hot Water Rebate on a Rinnai B26 Installed in Greenwich

Rinnai b26 Installation in Greenwich Sydney

The house was a beautiful sandstone home. We removed the old Rheem 315 litre hot water system and fitted a new Rinnai Infinity Builders 26 model on the sandstone wall. We needed to shave the sandstone back a little to allow for the Rinnai hot water heater to sit flush against the wall. We gently smoothed the area back so no one would ever notice the recess in the sandstone.
The Rinnai b 26 was just above the gas pipe and the water pipe which makes for a cost effective installation. The hot water pipe though was under the house where the old electric hot water system was. We needed to run an extra 5 metres inside to under the house to connect onto the existing hot water service.
With the job completed and the family all happy to have hot water again the cost for this job was only $1699 plus 4 extra metres at @$49 per metre. Total $1895. He also received a $500 cash back rebate from Jemena for going from an electric 315 litre hot water heater to a gas hot water system.

How Much Will My Gas Hot Water System Cost to Install or Change Over

How to quote your own hot water installation job?

Gas Hot Water System Cost for change over or a new installation.

We can change a gas storage(tank hot water cylinder) hot water heater over to a new Continuous flow like a Rinnai Infinity or a Rheem Continuous flow gas hot water system with using only 4 metres of copper tube. What you need to check for is a 20mm gas pipe which hopefully is right near to the current gas hot water heater. A 20mm pipe is about the size of your thumb.

If it is not right behind the hot water heater or near by, follow the gas pipe along the wall until it increases in size. From a 15mm(little finger size) pipe to a larger one. Calculate the amount of metres from the water heater to the increased gas pipe. Add this on to the 4 metre installation rule and multiply the extra copper metres by $49. This will give you a clear idea on the Gas Hot Water System Cost.  This same rule can be applied to the cold water supply also.

What is Included:

  • Installation of the NEW Continuous Flow Gas Hot Water Heater.  Any Brand. Rnnai Infinity, Rheem, Bosch and AquaMax. Brand New
    Model). All fixings Supplied.
  • Connections made to Cold and Hot water & gas pipes. Pipes must be at least 20mm for the gas

    or where you prefer.
  • Delivery of the Hot water
    heater is included
  • Includes plumbing valves, fixings, Copper bends & parts and 4 metres of copper tube
