Is your hot water cylinder overheating?

Extremely hot water is immediately dangerous to anyone using the taps and shouldn’t be ignored. An out-of-control hot water cylinder can cause permanent damage to your pipes. As water turns to steam and multiplies 1700 times in volume, it explodes. If air is hissing from the tap, this is often hydrogen caused by overheating.

Excessively hot water can indicate a tempering valve problem or an electrical problem with the thermostat, which can fail in the on position. Temperature fluctuations or warm water only suggest a replacement tempering valve is required. However, a pressure limiting valve (PLV) must be replaced or installed if the fault continues after servicing. Typically, if the HWC continues to overflow on the roof, it is due to fluctuating street pressures. 

With so many possibilities, don’t leave it to chance; contact your local hot water experts, and we’ll do the rest.

Life’s too short for a bad shower

A popular option while we fix your hot water cylinder issues is boosting the water pressure.

Installing a hot water booster pump or a relief valve on the exhaust gives you a better shower and sink washdown. Another solution is to fit a widebody shower hose and a low-pressure shower handpiece. Call us if a decent shower is on your wish list – we can make it happen.

No hot water? Maybe it is an electrical problem

Sometimes, the reason you have no hot water is because of an electrical problem. But don’t worry; if we discover it’s not a plumbing issue, we can arrange for an electrician to complete the job. Working across Tauranga and the wider Bay of Plenty area, we have an excellent network of highly skilled subcontractors who work to the same high standards we do. And they won’t charge the earth.

Common electrical causes for no hot water include:

  • The switch is off after being bumped at the rear of the closet; this happens more than you would think.
  • The power company has yet to open its relay, supplying no power. Sometimes, it’s best to wait 24 hours and see if there is still no hot water the following day. Alternatively, call the power company directly to ask.
  • A blown pole fuse at the roadside can cause your hot water cylinder to be without power, requiring a power company repair.
  • No power to the switch can be a blown fuse requiring resetting or replacement.
  • The thermostat on your hot water cylinder can fail in the fully on or off position, resulting in either cold or scalding hot water.
  • In some cases, the thermostat has overheating protection and can shut down in cases of thermostat failure or solar hot water overheating the HWC.
  • The electrical element can fail in the cylinder, resulting in no hot water; this would require replacement.
  • As a rule of thumb, if you place a hand on the top pipe connection on the tank and it is cold, you need an electrician; if it is hot, you need a plumber.
