Rinnai Enviroflo Heat Pump Questions & Answers

Hi Thomas, I have the V2 EHPA315VMA. This is the latest model with 315L capacity. The unit is fine, quiet when running but is relatively dumb, lacking features of other competitors such as wifi/programmable controller which makes it less effective when you're trying to save $ on running costs by soaking up excess solar generation. Instead it runs whenever it feels like it such as 1am.

From a Rinnai point of view. Their customer service was frustrating. The unit had an issue causing it to turn off after 20 seconds. A rep they sent out couldn't work out what was wrong leaving me without hot water for 2-3 days. After lots of phone calls and mucking around, in the end the unit couldn't handle higher voltage from the solar system. A part was replaced and its worked since.

If i were you I'd check out EvoHeat, Siebel Etron as alternatives.

Thank you for your enquiry, Thomas. The current range of Heat Pumps from Rinnai varies with our two smaller litre options (180L & 215L) that come standard with wifi sourced internationally and our two larger options (250L & 315L) made in Australia that is available with & without wifi. The sizing of the Heat Pumps will depend on the number of people living in the home. Our warranty applies to our cylinder, refrigeration components, other components & parts & labour with our Australian Made Heat Pumps receiving an extra 2 years warranty on the cylinder.

I'm researching for a new heat pump HWS and found that Rinnai is the top most confusing ones regarding smart capabilities. How the hell can I tell if the model comes with or without wifi when they just using the same model number? Most plumbers don't know if you ask them, and they don't even care. They just get the tanks and install them. How about make wifi standard across the board? Otherwise I'm just simply not going to waste my time to find out 'which one comes with wifi'.

Hi Rinnai, as mentioned. I’ve already called a few times already starting September last year. Juan has been asking for nearly a year as well.

When you call they don’t know and tell you to call back in a couple of months.

Any luck? Ive seen people talking about having it replaced, so it should be a spare part, Wether they will sell to an end user or not is another issue.

I called again today, and still no luck. Rinnai how is possible the people in your office said is still unavailable when for some it has already been replaced as part of their warranty and now there is even a image of the module in your latest manual? (See below)

I called them about a month ago and someone was going to book in to have a kit installed free of charge. Since then I've heard nothing. Called today as well to be bounced around to 3 different teams. No one has a clue what I'm talking about again. Super frustrating.

@Juan/Max - after PM'ing the mod on here they organised to have Gary come out for a field visit here in Melbourne. He's installed the wifi module for me and it looks to be working as expected with the schedules.

Thanks for organising this!

Hey KD - talk to Solargain and get an I-store. there are two models to choose from small and large depending on the size of your house. They are far better for the environment than gas hot water and help your home get off gas so you dont have to pay ongoing connection fees. Hot water typically represents 30% of household energy use so paying 4x less by using free energy in the air to heat water is a winner.

thank you is it in perth?

Rinnai dont allow you to do this with their models - they must be connected to a permanent supply of electricity. Pick a unit that the manufacturer has experience with solar too. i-store has a 5V-GND trigger which means your solar inverter with energy management relay (fronius has this not sure about other models) can turn on when set production values are met.

Hi Ross M, Thanks for the question. The STC number is an measure of the amount of non renewable energy saved by the system with a prescribed usage. For the heat pump, electricity is used when the heat pump is producing electricity, and in some cases directly from an electric element.

For a pumped solar hot water system, the pump that circulates water to be heated in the collectors, only uses a small amount of electricity. The bulk of the non renewable energy is from back up water heating.

In both types of systems many variables affect the performance of the overall system.

Thanks Rinnai Australia

Hi Matthew,

Please refer to our store locator link for assistance external link 

As we don't set as recommended retail price, it is a good idea to get a quote from a couple of different places.

Thanks, Rinnai Australia
