What Is The Most Efficient Hot Water System?

If you're planning to upgrade your existing hot water system, or need to complete a fresh installation, energy efficiency is always a priority. Not only is a hot water system that's energy efficient and which conserves water better for the planet, but it also ensures low energy bills.

To help with your decision-making process, we've ranked the most common forms of hot water systems and energy sources in order, starting with the most energy-efficient option.

If you're a light hot water user, a continuous flow system is ideal. Unlike tanked hot water systems, a continuous flow system only heats the amount of water you draw from the tap.

For households that will use a tank of hot water each day, a heat pump is probably the most economical option. Using around a third of the power that a conventionally heated electric tank system uses, heat pumps work by drawing warm air in and extracting the heat from it, using the heat energy to heat a tank of water.

Gas is cheaper per kW than electricity, so provided the efficiency of the system is the same, it's cheaper to power a traditional tanked system using gas, rather than electricity. Note that some electrical tank systems are extremely efficient, so may provide better value than an equivalent gas system. That said, gas systems are usually cheaper to purchase and install than electric systems, although may be more expensive to run in the longer term.

As stated above, an electrical tanked system may be a cheaper option in the long term than a gas-powered system. The type of system, as well as usage levels and tank size, may all tip the balance in favour of using electricity to power your hot water system.

The comparatively high purchase and installation costs of solar hot water systems need to be weighed up against low running costs.

To get the most from your hot water system, it's essential to opt for a hi-tech brand that optimises fuel efficiency and water conservation. We recommend Dux electric and gas hot water systems. Designed with economy and performance in mind, these systems are fairly priced at the same time as providing a reliable source of low-priced hot water.
