Hot Water Systems, Installation, Repairs and Quotes by Qualified, Experienced Heating Engineers in Perth

Hot water systems use a variety of heating methods to provide consistent hot water in your home, including gas, electric, solar or heat pump units. Zambezi Plumbing and Gas are experienced to work on all models of Water Heating Systems and our plumbers carry a comprehensive range of spare parts. We offer fantastic prices to suit your budget and keeping it affordable.

Electric Water Heating Systems

An electrically heated storage tank system is usually relatively cheap to buy and install, but is usually the most expensive to run, especially if it’s on the continuous (full day) rate.

Systems that run on off-peak electricity are much cheaper to run but need a larger tank as the water heated overnight has to last you all day. And off-peak electricity isn’t available to all homes.

A four-person household typically needs a 125–160L tank for a continuous system or 250–315L for off-peak.

Can be installed indoors or outdoors.

Electric instantaneous water heaters are also available.

Gas Hot Water Heating Systems

Natural gas is a good option if you have the connection for it. It’s cheaper than electricity and because gas rates don’t vary throughout the day, gas water systems can heat water as needed.

A four-person household needs a tank of about 135–170L. You also have the option of an instantaneous system.

Usually installed outdoors due to venting requirements but can be installed indoors with a flue.

Have an energy efficiency star rating.

Some have a pilot light, which uses a small amount of gas. Electric ignition is more economical, but in a blackout, you can lose your hot water supply.

Liquid petroleum gas (LPG) bottles are an alternative to natural gas – but expect to pay significantly more in running costs. They range in price from about $900 to $2000 (not including installation).

Solar Water Heating Systems

Consists of solar collector panels and a storage tank. A four-person household typically needs about four square metres of solar collector area (two panels) and a 300–360L tank. You need a large tank to allow for days with less sunlight (or more hot showers than usual).

If your panels can’t be installed in an ideal location, they may be less efficient, and you’ll need a larger collection area.

The storage tank usually has an electric or gas booster element to keep the water hot on days with less sunshine.

Comparatively expensive and time-consuming to install, but a well-chosen system will pay for itself in the long run due to very low running costs.

They range in price from about $2000 to $7000 (not including installation).

This is done in consultation with a third party.

Heat Pumps

A much more efficient form of electric storage tank system that works on the same principle as a fridge or air conditioner, by extracting heat from the air and using it to heat the water tank.

Units are usually integrated (tank and compressor together) but can also be split (separate tank and compressor).

They need to be installed in a well-ventilated area.

The compressor on the unit can be noisy, like the outdoor unit of an air conditioner, so you can’t install them too close to a neighbouring home.

They tend to work best in warm and temperate regions, but there are models designed to work well in cold climates too, and most systems have a booster element for days of chilly weather or high demand.

You’ll typically need a 270–315L tank for a four-person household.

They range in price from about $2500 to $4000 (not including installation).

Hot Water Storage Tanks

Storage tank systems, store a certain amount of heated water that is used throughout the day. Their biggest advantage is making use of cheaper off-peak energy tariffs to fill your water tank.

Most electric, gas, solar and heat pump water systems use a tank.
Mild-steel tanks can corrode over time; maintenance every few years can help prevent this. They usually have five- to 10-year warranties.
Many tanks have one or two “sacrificial anodes.” This is a metal rod inside the tank that attracts minerals and other impurities that would otherwise corrode the tank; the anode corrodes instead, ‘sacrificing” itself. Get a plumber to check the system and replace the anode every five years (or as per manufacturer instructions); doing this can add years to the life of the tank.
Stainless steel tanks are more expensive, but generally, last longer and don’t require as much maintenance as mild-steel tanks. They usually carry a 10-year warranty, but still require occasional maintenance (such as replacement of valves and seals).
Local water quality may dictate which type is best for you; check with the installer.
Tanks are insulated, but there is always some heat loss over time, so it’s good to install them in a sunny spot or in an insulated space.

Our qualified technicians may suggest replacing the system rather than replacing parts. This would be because it is not cost-effective to replace a part or if the water system is old and corroded. They will be able to advise you on the most suitable hot water unit dependent on your individual circumstances they are as conscious as you are about saving you money.
