Find a professional hot water system contractor in Hawthorn North

I have an instant electric hot water system in my apartment, it gets up to 45-50° in my laundry and kitchen taps but the shower and bathrooms are max 35-38°. I would like some help in locating and removing the tempering valve or valves that are limiting the hot water temperature in the bathroom. I'm happy to be flexible on the price.

We need the pipe removed or cut back to be flush with the wall & then re-plastered over the pipe

I am looking for someone to fix the following issues in a small apartment in Hawthorn, 3122: * Sink, shower, and kitchen taps: The water is not hot enough and is flowing slowly. In the bathroom, hot water is not working properly (it works a bit if the sink tap is in use). * Bathroom tap (Gessi Emporio brand): Hot water is not coming most of the time. It seems there may be an issue with the tempering valve on the hot water system (Stebel Elton electric unit, 8 years old) or tap servicing is required. However, I cannot be sure until a plumber investigates. Please provide a reasonable quote. - Due date: Flexible

Need a qualified plumber to do the service for my Rinnai gas boosted solar hot water system (solar 32, installed 2014). It’s currently taking longer to have hot water in the tap and producing high pitch noise when hot water flow is high. The system was serviced last year in July with the same problem. It was said to be caused by sediment in the water. - Due date: Flexible
