What To Do When Your Hot Water System Breaks

When your hot water system breaks down, either by a simple shut down or a more dramatic burst water tank and flooding, it normally happens very suddenly.

And once this happens, most people don’t take the time to look into all of their options as they take cold showers; instead, most people will simply replace the hot water unit with something identical or equivalent right away.

This tends to mean that many people miss out on the opportunity to find a better product.

The old one worked fine, so let’s just get the same thing to avoid trouble

Because hot water takes up so a large part of your household power consumption (generally around one quarter of it), it is well worth reviewing how much power your system uses and comparing it to some alternatives before your system breaks down, while you still have the leisure.

You may find before long that many other HWSs (hot water systems) can save on energy and money while being friendlier to the environment.

Another thing to consider is any new regulations aimed at lowering household energy use in your state, as a new electrical system may not even be an option for your household.

What Is The Difference Between An Electric Hot Water Storage Tank, A Gas Hot Water Storage Tank, Solar Hot Water, & Hot Water From A Heat Pump?

The biggest decision you will need to make about your new hot water heater is method of heating (electric, gas, solar, or heat pump).

Here is a hot water heater breakdown of each to give you a general idea of the differences:

How Much For An Electric Hot Water System?

Electric hot water systems may seem to be the most inexpensive option because they are relatively cheap to purchase as well as install.

However, over time these systems will actually cost you more in energy costs, especially if you are using a continuous or full day rate.

If your system runs on off-peak electricity it can be much kinder to your energy costs, but will also make it necessary to have a larger tank so that the water heated overnight will last throughout the day.

Please investigate your particular energy situation as off-peak electricity is not available for every home.

For an average four-person home, you will generally need a 125-160 litre tank if you have a continuous system, or a 250-315 litre tank if you are using off-peak electricity.

Electrical hot water units can be installed either inside or outside of the home.

Instantaneous electric water heaters are available as well.

And finally an electric hot water storage tank will typically cost between $500-$1500 to buy plus installation.

How Much For A Gas Hot Water System?

Natural gas can be a great option if your home has access to it. Generally the rate is much cheaper than electricity (but unfortunately gas prices are rising).

Another advantage is that gas rates do not fluctuate throughout the day, and can simply heat water as needed.

For a four-person home you should have a tank of around 135-170 litres.

Instantaneous systems are also available for natural gas. These systems tend to be installed outdoors on account of the venting requirements, though it is possible to install them inside if you have a flue.

These systems have an excellent energy efficiency rating. Some of them use a pilot light which uses a very small amount of gas, and others use electric ignition which is more economical.

The advantage of the pilot light however is that you can keep your hot water during power outages.

One alternative to natural gas is LPG or liquid petroleum gas, but the running costs will be significantly higher. Not including installation, a natural gas system will cost around $900-$2000.

How Much For A Solar Hot Water System?

These systems have solar collector panels and a storage tank. For a 4 person home, you will generally need two solar panels, or four square metres, along with a 300-360 litres tank.

The larger tank is needed to make up for days of minimal sunlight. Also note that four square metres of panel is recommended for an ideal collection position.

If your home doesn’t allow for your panels to be set up in an ideal place where they get a lot of direct sunlight, you may need to invest in more panels.

Some solar hot water systems also have an electric or gas booster element in the storage tank as a backup, to keep you going through periods without much sunshine.

Unlike electric hot water systems, solar hot water systems are typically the most expensive to buy as well as install.

But also unlike electrical hot water heaters, a well-functioning solar hot water heater will be very inexpensive in the long run as the running costs can be extremely low.

You may also be able to take advantage of government rebates or other incentives to help out with the purchase cost.

Solar systems, not including installation, will generally cost around $2000-$7000.

How Much For A Heat Pump Hot Water System?

This is an efficient kind of hot water storage in that it works according to roughly the same principle as a fridge or air conditioner: it heats the water in your tank by extracting heat from the air.

Normally these systems have the tank and compressor integrated together, but a split system with the tank and compressor separated are also available.

These water heater systems need to be installed in a well-ventilated place, so outdoor installation is ideal.

Be aware that like air conditioners, the outdoor units of these systems can be quite noisy, so it is better not to install them too close to a neighbouring home.

These systems are ideal for warmer climates, though they can be made to work in a colder climate by including a booster element to keep your water warm on colder days.

For a four-person home, you will generally need a tank of 270-315 litres. You can also find government rebates or incentives to help offset the relatively high cost of purchasing and installing one of these systems.

The price for these systems will range from $2500 to $4000 (minus the installation).

What is the best option… a hot water storage tanks or an instantaneous / continuous flow hot water systems

Most of the hot water systems described above, regardless of the heat source, rely on a mild-steel tank for storing hot water.

These tanks can corrode over time, but regular maintenance (like flushing a hot water heater) can help to extend their lifetimes, and most tanks will come with a five to ten year warranty.

Most tanks will have a rod inside called a “sacrificial anode” meant to attract the minerals or impurities that would attack the tank instead, so that the anode will gradually corrode instead of your tank, sacrificing itself, so to speak.

Replacing the anode every five years (or less depending on the manufacturer’s instructions) can help your mild-steel tank to last for a long time.

You can also buy a more expensive stainless steel tank which will typically last longer and require much less maintenance. Stainless steel tanks will usually have a 10 year warranty, and will still need a little bit of regular maintenance (to replace seals and valves).

The quality of your local water might determine which type of tank is best for you, so it’s best to consult your installer. Hot water storage tanks are generally insulated, but over time there can still be some heat loss, so it’s best whenever possible to install the tank in a sunny spot or in a well insulated area.

If you’d like to dispense with the tank altogether, there are also continuous flow or instantaneous water heating systems which simply heat as much water as you need as you go.

Keep in mind that they are not literally instantaneous, and can often take a few seconds for your water to become hot, especially if you have a long length of pipe between your heating system and your tap.

Most heating systems like this use gas, however there are options available that use electricity. Because you can avoid any heat loss as there is no hot water stored anywhere for long periods of time, these systems are often much cheaper to run once you get them set up.

Keep in mind with the electric versions however that you will be paying more for any heating that is done during peak hours. The size of these systems is measure by flow rate in litres per minute, and the size you need depends less on the number of people in your home and more on the number of water outlets in your household. In general, for a two-bathroom home you should have a flow rate of roughly 22-24 litres per minute, but you should consult your supplier for a more accurate estimate.

Also keep in mind that some members have advised us that their continuous flow heaters were not turning on on account of having too high a trigger point for the heater to turn on along with low flow shower heads. So if you do have low flow shower heads it will be best to make sure that the trigger point of your continuous flow heater is set appropriately.

What size hot water tank for an average household?

Generally speaking a household will use about 50 litres of hot water per day. If you wash clothes in hot or warm water, take long showers, or use a dishwasher then the average amount per person could be considerably higher.

It is recommended to get your supplier to analyse your household and its water needs and then recommend some appropriate options for you. Your supplier should be asking you questions about how much water you use as well as when you use it.

Does everyone in the house shower in the morning or in the evening? Do you wash your clothes in hot or warm water? It is best when possible to get quotes from more than one supplier.

For most homes, solar heating systems are generally the most efficient and cheapest to run, but this option can be impractical for some homes for a variety of reasons, and your supplier will be able to recommend a number of different efficient and cost-effective options if solar heating isn’t ideal for your particular situation.

What Hot Water System Has The Best Energy Star Rating?

Gas water heating systems generally have the best energy star ratings for efficiency (the more stars it has the better, with the highest rating being six starts).

This is a good way to quickly assess the energy efficiency of heating systems, but keep in mind that this rating scheme is not regulated by the government.

How To Find The Best Hot Water Plumber

Hot water systems problems are no joke, which means caution is needed when hiring a licensed Sydney hot water plumber

Hot water issues happen at the most inconvenient times: You wake up to find hot water pouring from a collapsed ceiling; return home after a vacation, ankle-deep in water; or discover your hot water tank is just not heating the water

It might sound sensationalist, but when your hot water unit packs it in, it is generally safe to say you automatically go into panic mode.

You search for “a local plumber near me” – whom you find either with the aid of Google or in the Yellow Pages – and hope for the best. But the trouble is – if the plumber isn’t fully licensed and affiliated with the trade association and they do a bad job up, cold water might be the least of your concerns.

Poor hot water installations and the primary need for hot water heater manufacturers to be price competitive within the market have also prompted hot water system manufacturers to be more stringent with any warranty claims.

It is important to note that a hot water heater manufacturer is within their right to void a warranty claim if the hot water system installation is non-compliant with the National Standards.

There is, however, a distinct line between product failure and failure due to poor installation.

Typical problems that arise when using non licensed hot water plumbers can include leaks, poor water pressure, bad odours from pipes and drains, flooding, damp and mould. Other more serious issues can include contamination of the drinking water, scalding and burns, the breeding of disease, and potential tank explosions.
