Start with how your household uses hot water

Consider how many people live in the property, when showers and appliances are commonly used, and whether demand arrives in short peaks. A system that is too small can struggle at busy times. One that is unnecessarily large may use more space and energy than the household needs.

Tell your plumber about planned changes such as an additional bathroom, renovation or growing household. Designing for the property you expect to use is more useful than replacing an old unit like-for-like without reviewing demand.

Compare the main system types

Electric storage

Electric storage systems are familiar and can suit many properties. The installation needs a suitable location, electrical supply, safe drainage for relief valves and enough capacity for anticipated use.

Gas systems

Gas storage and continuous-flow systems can provide strong recovery or on-demand heating. Suitability depends on the gas supply, appliance location, ventilation, flue requirements and the length of hot-water pipe runs.

Heat-pump systems

Heat pumps transfer heat from surrounding air into the water. They need appropriate outdoor space, airflow and thoughtful placement because the equipment produces sound and cool discharge air while operating.

Location affects performance and convenience

Long pipe runs can mean a longer wait for hot water and more cooled water left in the line. Positioning the unit sensibly in relation to bathrooms, kitchens and laundries can improve everyday usability. Access for future servicing also matters.

Questions to ask before installation

  • What capacity suits the household’s peak demand?
  • Is the existing electrical or gas supply adequate?
  • Where can the system be installed safely and serviced easily?
  • Will valves, pipework or drainage need upgrading?
  • Does the quote cover removal of the existing unit and commissioning?
