Besides renovating your home replacing your hot water service is likely to be one of the major costs your household will face. With the cost of heating hot water ranking second in dollar spend for household electricity costs, Whywait Plumbing believes it is imperative that you are well informed before making any decisions on your new hot water service.

With the plethora of makes and models available, the push for energy efficient solutions and a range of next generation water heaters on the market it is now more important than ever to do your research to ensure you select the best option available for your families hot water needs.

If you have been thinking “which hot water service should I buy?”, Whywait Plumbing will help by explaining the options available in the marketplace.

Electric Hot Water Service
Electric hot water services are the most common form of heating hot water. They consist of a storage tank with an element that is thermostatically controlled. As hot water is drawn off and cold water enters to replace it the element comes on to reheat the water.

Benefits

  • Ideally suited for like for like replacement.
  • Available in a large range of makes, models and sizes.
  • Readily available for same day installation.
  • Reasonable up-front cost.
  • Suitable for connection to off-peak electricity tariffs.

Limitations

  • Higher daily running costs unless connected to off-peal tariffs
  • Limited capacity if connected to off-peak tariffs, so you have the possibility of running out of hot water should the demand for hot water exceed the capacity.

Gas Hot Water Service
Gas hot water services come as either the traditional storage tank, which works in a similar way to electric but uses gas rather than electricity as it’s source of energy, or instantaneous gas hot water services which only activate when a hot water tap is turned on. Instantaneous gas hot water services have become more popular than the traditional storage tank due to their superior efficiency. If you do not have reticulated natural gas in your suburb then LPG models are available.

NB: It is imperative that the correct sized unit is installed for your house to ensure adequate delivery of hot water.

Benefits

  • Available in a large range of makes, models and sizes.
  • Reasonable up-front cost.
  • Provide on demand hot water.
  • Energy Efficient Solution

Limitations

  • LPG running costs can be expensive if hot water demand is high.
  • Need to refill gas bottles if running on LPG.
  • Whilst natural gas is cheap to run there will also be service fees charged by the energy retailer.

Solar Hot Water Service
Solar hot water services capture and retain heat from the sunlight and transfer this heat to the water stored inside the tank. Solar hot water services are available in both roof mounted and split systems. Roof mounted solar systems have both the tank and solar collectors or panels located on the roof and split systems have the solar collectors or panels on the roof and the tank on the ground with a circulating pump connecting the two. The heart of a solar hot water system is the collectors as they trap the heat and transfer it to storage, so for optimum operation they need to be located on a north facing roof. Solar collectors are available as both flat panel or the more efficient evacuated tube system.

Benefits

  • Energy efficient Solution.
  • Low to no running costs.
  • Available in a range of makes, models and sizes.
  • Reduced greenhouse emissions.
  • Eligible for government rebate.

Limitations

  • Higher up-front cost
  • Dependent on sunlight for heating so operation is affected by the weather and may also need to boost electrically during the winter months to ensure an adequate supply of hot water.
  • Any hot water used at night will not be reheated until the next day unless the electric booster is on.
  • Must still be connected to electricity so will be charged a small service fee by the energy retailer whether you use electricity or not.
  • Alters aesthetics of the property.

 

Heat Pump Hot Water Service
Heat pump hot water units are designed to deliver hot water day or night no matter what the weather conditions. A heat pump unit uses a fan to draw in ambient air which is absorbed by a refrigerant gas. As the warm gaseous refrigerant circulates through the system it passes through a compressor where it’s pressure and temperature rise. The hot refrigerant then passes through a heat exchanger which heats the water. The refrigerant is cycled back into the system, and the hot water is pumped into the storage tank.

Here at Whywait Plumbing we recommend the Sanden “Eco” Hot Water Heat Pump the most energy efficient hot water heat pump currently on the market as certified by the Australian Government Clean Energy Regulator.

Benefits – Sanden Hot Water

  • Low running costs proven to use 20% of the electricity costs of electric storage tanks.
  • Available in a range of sizes.
  • Energy efficient.
  • Reduced greenhouse emissions.
  • Manufactured for Australian conditions.
  • Fast recovery rate.
  • Eligible for government rebate.

Limitations

  • Higher up-front costs.

Replacing Your Hot Water Service? What You Need To Know

Replacing Your Hot Water Service? What You Need To Know

Replacing Your Hot Water Service – How Will You Know What’s Right For You?

When replacing your hot water service the most common question asked is what will it cost?
Whilst price is always an important consideration, at Whywait Plumbing believe that there are other equally important factors. This article will help you make an informed decision.

Should The Price of the Replacement Hot Water Service Be The First Consideration?

Besides renovating your home, replacing your hot water service is a major cost. It is often an expense that occurs with very little warning.
Unfortunately, unless you like cold showers, this gives you little time to carefully review available replacement options.

Hot water systems are not all created equal and the choice you make today will be one that lasts for the next ten to fifteen years. With ever-increasing energy costs impacting household budgets, having an efficient and well maintained hot water service has never been more important. A cheap hot water service may cost you a great deal more in ongoing expenses.

With So Many Hot Water Systems On the Market How Do You Know Which One To Choose?

With modern technological advances and the push for energy-efficient heating solutions, it’s no longer a matter of just replacing your hot water system with like for like.  So how do you know which hot water service to buy?

Hot water services are available in electric, gas, solar and heat pump models, and all come in a huge range of sizes. Purchasing the right hot water service for your needs is something you should seek advice about from a qualified hot water specialist. With a little help from Whywait’s Hot Water Specialists you will be able to select the system that best suits your situation.

Hot Water Service FAQ’s

Before making any decisions about a hot water service replacement you will need to think about:

  • What size is your current hot water service and have you ever run out of hot water with your current hot water system?
  • Does your current hot water service operate on an off-peak electricity tariff?
  • Are your hot water needs likely to increase, decrease or stay the same over the next five years?
  • Do you intend to remain in your current property for at least the next five years?
  • What is more important to you the initial up-front installation cost or the ongoing running costs?
  • Is the quality of the product and length of warranty a consideration when comparing hot water services?

Once you have answered the above points it will be time to consider the available options.

Do Solar Hot Water Systems Work In Winter?

Do Solar Hot Water Systems Work In Winter?

Ever wondered if solar hot water systems work in winter? The short answer is Yes, solar hot water systems do work in winter, it’s not that simple though so let us explain.

Solar Hot Water Collectors

The heart of a solar hot water system is its hot water collectors.  Solar hot water collectors capture and retain heat from the sun then transfer this heat to the water stored inside the tank.

So how do solar hot water collectors work?

Put simply, heat and infrared radiation are produced when short wave radiation light hits the reflective surface of the collector’s absorber, which is then trapped inside the collector.
Fluid, usually water, in contact with the absorber collects the trapped heat and transfers it to storage.

A common misconception is that your solar hot water system does not operate as well in the winter due to the cooler temperatures when in fact the real reason is the fewer hours of sunlight.

Solar Hot Water Collector Efficiency

The design of your solar hot water service has incorporated some technical factors to make the collector as efficient as possible.

Flat Panel Solar Collectors

The most common flat panel collector has a large surface area to maximise exposure to the sun. The coating used for the absorber has been formulated to absorb as much heat as possible and the glass is specially designed to allow as much light energy through as possible. Read more about Flat Panel Collectors.

A common misconception is that your solar hot water system does not operate as well in the winter due to the cooler temperatures when in fact the real reason is the fewer hours of sunlight.

Evacuated Tube Collectors

If your system has evacuated tube collectors then they will have long, skinny absorbers inside the glass tube and all the air will have been sucked out, which makes it highly insulated. Read more about Evacuated Tube Collectors.

Solar in a Warmer Climate

Here in Queensland we have a great climate for using Solar Hot Water and in most areas do not need to worry about pipes freezing. So when Queenslanders, or people living in a tropical climate, ask if solar hot water systems work well in winter, there is little to be concerned about. We still need to take some simple steps to ensure our solar hot water system is operating at its best during these cooler months though.

Handy Solar Hot Water Tips

Listed below are some handy tips to ensure your solar hot water system is operating to maximum efficiency and you don’t run out of hot water:

  • Cut back any foliage casting shadows or blocking sunlight from the panels.
  • Ensure there is no built up dirt or grime on the panels and clean with soapy water as required.
  • Check that the relief valve is operating correctly and not leaking.
  • If you run your dishwasher at night check it is connected to cold water only.
  • Any laundry loads done at night are cold water washes.
  • Review you evening hot water usage as remember any hot water used after dark won’t be reheated until the sunlight hits the panels the next morning.
  • Use the electric booster on wet, cloudy or days of heavy demand.
