Water Heating Solutions
Electric water heating
Up to 50% of your monthly energy bill is for water heating via a hot water cylinder and most New Zealand homes have an electric hot water cylinder. Older cylinders tend to be small and low pressure, whereas modern electric hot water cylinders are high- or mains-pressure and hold 180 litres or more. If you regularly run out of hot water, it is likely you have a low-pressure cylinder. If it has been poorly installed, a low-pressure hot water system often can only run one tap at a time with reasonable pressure.
Mains-pressure cylinders are more expensive, give faster flow and allow you to use a wider range of tap fitting, but will use more water and energy. A family of four will typically need about a 200-litre capacity hot water cylinder if they’re not going to regularly run out of hot water under normal use.
Older hot water cylinders and pipes can often be poorly insulated, leading to heat loss. Adding a cylinder wrap could save you up to 1 kWh/day and pay for itself in less than a year.
Heat pump water heating
Heat pumps are far more efficient than ordinary electric water heaters. Heat pump water heaters move heat from the air to the water in the tank instead of generating heat directly via an element. They work like a refrigerator in reverse: generating heat, not cooling.
There are two main types of systems: an all-in-one system where the heat pump is part of the hot water cylinder and a split system where the heat pump is located outside and the hot water cylinder is inside the house.
All-in-one systems are available for both indoor and outdoor locations and are a good option when renovating, building new or replacing old cylinders, whereas a split system can be retrofitted to your existing tank provided it is not too old.
Heat pump water heaters cost more at the outset than a standard electric water heater. However, a well-installed heat pump water heater would reduce your hot water bill by two thirds. Their efficient operating costs mean that for moderate-to-high hot water users, payback time will be relatively short.
- A properly installed heat pump water heater could cost you up to 60% than a standard hot water cylinder in electricity.
- Hot water heat pumps can be noisy (as noisy as a standard heat pump).
- Hot water heat pumps are less efficient in winter.
Saving hot water saves you money
Here are some handy tips on hot water savings:
- Consider having your hot and cold taps separate. It’s more common to have a mixer, so if you do, make sure the handles are left in the cold position. That way you don’t get hot water unless you actually need it.
- Use cold water for washing clothes, rinsing, filling the jug etc.
- Turn off the water cylinder when you go on holiday.
- Have showers instead of baths and keep your showers relatively short.
Get a Wellington Central plumber to:
- Replace your shower head or fit a flow restrictor to your shower – it can work wonders on a hot water system used by teenagers.
- Check and fix any leaks or drips (especially relief valves on mains pressure hot water systems and under your house).
- Make sure your cylinder and hot water pipes are properly insulated.
- Regularly check your hot water cylinder. If you notice anything that doesn’t look (or sound) right, have one of our team check it over for you.
