Regular maintenance is critical for the Thermann 250L Electric Hot Water System to function efficiently and last long. One of the first things to pay attention to is the thermostat. Periodically checking the thermostat is crucial for accurate temperature regulation.

    Great service. We were about to move into a house without hot water! Were able to get to us urgently and have us up and running. Professional, friendly service! Reasonable pricing too.


    The JR Gas and Water team was very professional and friendly. They arrived on time and exchanged my hot water system within 2 hours. Will definitely use them again in the future.

    JR Gas and Water were fast, efficient and very reliable. They sent a quote quickly that was itemised and comprehensive. I was able to approve the quote online and they were out the next day to fit the new hot water system. As the family have a very ill family member we were all very grateful. We had tried another service just before this company and they were all over the show with lots of comments about "extras", after providing an initial quote. So glad we changed to JR Gas and Water!
