"The Plumbing Gazette of Glenelg"

If you own a Bosch Hot Water service which still has a pilot light the chances are that it could well be at least 8 to 12 years of age.  These units such as the Water Wizard and P models such as the 10P, 13P and 16P were some of the earlier models of Hot Water units which Bosch introduced to the Glenelg Hot Water market.  These units are very much like an old model car, they can be pulled apart and worked on (no computers).  There is always a question of fees ability of course, how old is the unit and can the parts actually be dismantled (corrosion being a big factor especially along Adelaide's coastal suburbs such as Brighton, Largs Bay and Henely Beach).

Mayfair Plumbing and Gasfitting are very proud of the fact that we are a recognised authorised Bosch installer across South Australia and its particularly in the coastal suburbs of Adelaide around Somerton Park, Hallet Cove, Grange, West Beach and Semaphore that we quite often find ourselves trying to revive these 10P's, 13P's and 16P's and Bosch Water Wizards.

During the windy nights and days the pilot flame inside of these older style systems can get blown out and depending on the condition of the ignition buttons it can require the services of a licensed hot water plumber to have the ignition kit over hauled to then enable the pilot light to be re-lit.  Another VERY common fault with this model is it only delivers warm water.  We find that 97% of the time this is related to the water section at the bottom of the unit.  There are numerous delicate parts in this component of the Hot Water Service, but the main contributor to a service fault is called the diaphragm.  Over many years of use this part wears out and gets splits or pin holes in the rubber.  The rubber becomes brittle over time and is therefore susceptible to splitting and deforming which in turn doesn't allow the system to heat the water adequately, hence the report of warm water only or in some extreme cases not Hot Water at all.

There can also be another not so common fault with these Bosch Instantaneous Hot Water Services and that can be a failed thermostat.  Typical faults displayed during this error is extremely hot water or freezing cold water.  When a thermostat does fail it can be a sign that the system is due to be upgraded.  This is because the new thermostat and labour can be quite expensive and it usually only occurs when the Hot Water Service is at the end of its life and once this part has then been replaced the likely hood of another fault showing up in the near future is quite likely.
