We have no issue with hot water when it fires up!! Our issue is we have to remove front cover and light up with a lighter...battery ok and sparks but wont fire up without using the lighter.

This unit is installed in a remote area and does not get a lot of use. In the 6 months I have had it it has only been used 20 or 30 times, Now it has stopped working. Plenty of waster pressure going into the unit,full gas bottle,new battery. Can anybody tell me what to do. The unit was reccomended and I thought I had made a good choice,but maybe not,
Any clues ?.

IF totally buggered it should be under warranty (1300555545 Rinnai serv no at least in WA)
ours is working ok now that we turned the water flow & temp adj clockwise to decr water flow AND my plumber removed the Govt required Temp Limiting device which most plumbers say is the problem if water not hot enough/( nanny state... put in.so babies dont get scalded)
ps..when my solar panel rebate finishes in 4 yrs, I'll be cutting off all gas to house, buying the biggest storage batt & solar hot water elec boosted)

We have since got it working 95% of the time - we had to completely open up the gas regulator which the manual says must be installed (plumber showed me how) and we have to be very careful of air bubbles inside the hot water system (requires draining of the HWS on the inlet side to try and fix). Also I highly recommend removing any flow restrictors on any taps/shower heads You want to ensure your water is flowing at more than 4 litres per minute. I did this by placing a bucket under the outlet, turn on hot water only and see how much water goes into it over a minute - a bucket is usually about 10 litres. You need 4 litres for the HWS to attempt to warm the water. The Temp limiting device might be a factor if there is air bubbles in the HWS - however we still have ours as set up and in summer the water is hot, in winter it is just warm, we are considering setting up a pre-heater for the water before next winter.

Thanks for the question Scott, it can be hard to provide a diagnosis without examining the unit. We do have a technical help line who can troubleshoot over the phone and arrange a service call out if required. If the fault is a manufacturing issue, you are still within your warranty period for the unit.
