Hot Water Plumbing – Hot Water Services


This is one no one wants to get stuck with! Having no hot water can be incredibly disruptive to the entire household!
Unfortunately no one knows exactly when its going to stop, but there are a few tell tale signs that the Hot Water System is not as healthy as it used to be!


Rusty/Dirty water coming through your taps when you first turn them on, there is water leaking from the actual tank, and the temperature may be effected. The age of the tank is also very important. If your tank is over 8 years old and you are experiencing the above issues, then you probably need a new tank.

When you have your tank installed or serviced by The Plumbing Team, they will place a sticker notifying you of the date of the repair, so you will never have to guess!!

Water heating can account for a big chunk of your household energy use, so it can be a great idea to review your hot water usage well before your current system dies and checking out the alternatives – you may find a system that saves energy and money and is kinder to the environment.



New limits on electric HWS

For many people, replacing an old electric hot water system with a similar model is no longer an option. Standard electric systems produce around four tonnes of greenhouse gases per year (on average) – similar to an average sized car, and around three times as much as gas or solar HWS. To reduce this environmental impact, government regulations now limit the installation of electric HWS:

Electric HWS can't be installed in any new detached, terrace or town house, or any such existing property where there is access to piped natural gas (some exemptions apply).

From 2012, this will apply to all existing detached, terrace or town houses.

You don't need to replace a working electric HWS, but if you own a detached, terrace or town house, and it currently has an electric HWS, you need to consider a gas, solar or electric heat pump for your next replacement. Electric HWS are still available for apartments and other homes where gas, solar or heat pump systems aren't feasible. There are two main types of water heater: storage and instantaneous. Instantaneous heaters heat the water instantly, while in storage heaters it's stored in a tank.

STORAGE WATER HEATERS

The water is heated to a relatively high set temperature (usually between 60 degrees celsius and 70 degrees celsius) and kept ready for use in a tank. When you use hot water, it's drawn from the top of the tank and replaced by a layer of cold water at the bottom. The temperature drop is sensed by a thermostat, which turns on the heater at the bottom of the tank.Although the tank is insulated, it's constantly losing energy. So the water temperature drops over time unless it's reheated. If you draw off hot water faster than the cold water can be heated up, the cold layer can eventually move to the top of the tank – and you'll run out of hot water.

Why not install a hot and cold filtration system, just think….. never wait for a kettle to boil again!

INSTANTANEOUS WATER HEATER

This type only heats as much water as you need, when you need it. If you turn on the tap, cold water flows through a heat exchanger, igniting a gas burner or switching on an electric element. So there are no heat losses, and as long as there's gas or electricity, you'll never run out of hot water.

SIZE

The size you need (the flowrate in litres per minute) depends on the number of hot water outlets the heater has to serve, more than the number of people in the household. As a general rule, for a two-bathroom house you need a flowrate of about 22-24 L/min. But talk to your Plumbing Team Plumber to find the capacity most suitable for your situation.
