Fault codes, cold showers and the fixes
A Rinnai Infinity that’s flashing a code or dropping to cold mid-shower is usually telling you something simple: an ignition or flame problem, a flow sensor, a blocked filter, or a gas supply issue. We diagnose the code, carry the common parts, and most repairs are done in one visit. Units that have run for years without a service are the ones that fail on a frosty Hamilton morning, so a service every couple of years is cheap insurance.
Replacing an Infinity, or moving on from gas
When a unit is past about 15 years and has a major fault, a new Infinity is often the better money, and we’ll quote both so you can choose. Because our gas work is signed off by a certifying gasfitter, the replacement comes with its gas pressure test and gas safety certificate, and we can upsize the unit if your household has grown. If you’d rather come off gas altogether, we’ll give you a price for a hot water heat pump alongside it, including disconnecting and certifying the gas.
What happens when you get in touch
The same four steps on every job, so you know what's coming.
- 1
You get in touch
Call, or send the quote form with a few photos. We take the details and book a time to look at the job, or quote from the photos if they show enough.
- 2
Written quote, usually the same day
We send the quote the day you ask. For common jobs the pricing is ready, and we tell you if a repair will do instead of a replacement.
- 3
The job
Non-urgent jobs are usually done within a week. Water or gas is off for the minimum time, and you do not need to be home if we can get access.
- 4
Paperwork and tidy up
Gas work comes with a gas safety certificate, and consented work with the PS3, pressure test and as-laid drainage plans the council needs. Then we clean up and invoice.

Rinnai Infinity repairs and replacement: your questions
My Infinity is showing a fault code. What does it mean?
The codes point at the problem area: ignition, flame, overheating, water flow or a sensor. Some clear with a reset; most mean a part or a service. Tell us the code and send a photo and we'll tell you what's likely before we come.
The water goes hot and cold in the shower.
Often a flow or temperature sensor, a dirty filter, or a tempering valve downstream. Sometimes it's low gas pressure. It's usually a service or a small repair.
How often should it be serviced?
Every couple of years keeps it efficient and catches worn parts early. Units that have never been serviced are the ones that fail on a cold morning.
Repair or replace?
A unit under about 10 years is almost always worth repairing. Past 15 with a major fault, replacement usually makes more sense, and we'll give you both prices so you can decide.
Can I get rid of gas altogether?
Yes. If you'd rather come off gas, we can replace the Infinity with a hot water heat pump, disconnect and certify the gas, and remove the old unit.
Are you a Rinnai service agent?
No, we're independent. We recommend and fit Rinnai because they're reliable and parts are easy to get in Hamilton, and we work on other continuous-flow brands as well.
