Water Heaters: Your essential buying guide
Common options include storage tank Water Heaters, tankless or on-demand models, heat pump water heaters and solar-powered systems. Storage tanks keep heated water ready to use, while tankless models heat water as needed. Heat pump and solar options may suit shoppers prioritising energy use, installation space and longer-term running costs.
Start with how many people need hot water and how often it will be used. A larger household usually needs a larger tank than a couple or single user. Also measure the available installation space before buying, as the unit needs to fit comfortably where it will be placed.
It depends on your priorities. Tankless Water Heaters heat water on demand and can save space, while storage tank models keep a quantity of hot water available for immediate use. Compare the purchase cost, installation requirements, available space and your expected hot water demand.
Yes, if you want to reduce energy use over time. More efficient models can use less electricity or gas to heat water, which may help lower running costs. Check the product’s efficiency information and compare it alongside capacity, type and installation needs.
Water Heaters commonly last around 8 to 12 years, although this depends on the type of unit and how well it is maintained. When comparing products, check the warranty information and consider whether routine maintenance will be easy to manage.
Maintenance can include flushing the unit to reduce sediment, checking pressure relief valves and inspecting anode rods where applicable. Always follow the product manual, and use a professional if you are unsure about any checks or servicing.

Water Heaters provide hot water for domestic use, and the best choice depends on your household demand, available space, preferred technology and energy-efficiency priorities. Before buying, compare capacity, heater type and maintenance needs so the model suits both the property and daily use.
Capacity is one of the most important factors when comparing Water Heaters. A larger household will generally need more stored hot water than a smaller household, especially where several people may need showers, washing up or other hot water use close together.
For storage tank models, consider both the number of users and the pattern of use during busy times of day. Also measure the intended installation area carefully so the heater fits without creating access or clearance issues.
Storage tank Water Heaters keep hot water ready for use, which can be convenient where a steady supply is needed. The main points to compare are tank size, installation space and how quickly the stored hot water may be used during peak demand.
Tankless, or on-demand, Water Heaters heat water when required rather than storing it in a tank. They can be a practical option where space is limited, but shoppers should still consider upfront cost, installation complexity and whether the unit suits their expected hot water needs.
Heat pump and solar-powered Water Heaters are also available. These may appeal if you are comparing options with energy efficiency in mind, but they can differ from standard models in installation requirements and initial cost.
Solar-powered models can reduce reliance on conventional energy sources, but performance may depend on sunlight availability. Compare the practical setup requirements as well as the potential long-term energy benefits.
Energy efficiency matters because Water Heaters can use electricity or gas to heat water. Models with stronger efficiency credentials may cost less to run over time, although the purchase price and installation needs should be weighed together.
When comparing products, look for clear efficiency information from the manufacturer and balance it against capacity, heater type and how frequently hot water will be used in the home.
Routine care helps keep a water heater working properly. Depending on the model, this may involve flushing sediment, checking pressure relief valves and inspecting anode rods.
Water Heaters often last around 8 to 12 years, with maintenance and product type influencing service life. Check the warranty and care instructions before buying so you understand what ongoing attention the unit may need.
