Renovate with Rinnai

Renovate with Rinnai

Water heating is the single largest energy use in homes. Electric cylinders also take up unnecessary space. So it makes sense to take a closer look at the systems you use when planning for renovations.

Committed to smart, energy-efficient solutions, Rinnai has the answer to endless hot water with financial, lifestyle and environmental benefits — the Rinnai Efficiency Continuous Flow Water Heater.

Gas operated, the Rinnai Efficiency is, at its heart, a continuous flow hot water system, providing unlimited hot water and temperature control with 95% energy efficiency.
Available in LPG and Natural Gas options, the Rinnai Efficiency can be mounted on the outside of a house or building, freeing up space for that extra linen cupboard or pantry.

Check out the benefits!

The Basic Principle

By including a secondary heat exchanger, energy that would normally be lost is recovered and then used to heat the water. This is evident in the flue gas temperature; for a Rinnai Efficiency, temperatures are in the region of 60°C, compared to 200°C for standard continuous flow systems.

Financial Benefits

Increased energy efficiency = lower running costs. The same amount of energy produces many more litres of hot steaming water.
For example, in an average household using about 500 litres a day at 45°, the Rinnai Efficiency can effectively save nearly half the running costs of an electric tank.*
Lifestyle Benefits

As well as cost saving benefits, the Rinnai Efficiency also offers a number of lifestyle benefits, which include continuous hot water and space saving. The space saving benefit has been highlighted in the bungalow renovation on Kenyon Ave in Mt Eden (see above).

Environmental Benefits
Using gas as a direct source of energy — as opposed to using electricity which is generated from burning gas — contributes to a significant reduction in the manufacture of greenhouse gases. In fact, electrically heated hot water produces nearly twice the CO2 emissions of water heated directly with gas.
