Electric tankless heaters are typically the most energy-efficient option, but your home may benefit more from a conventional water heater if your household uses large amounts of water.
Water heaters use about 20% of a home's energy. An important element of an ENERGY STAR Home Upgrade is a heat pump water heater that earns the ENERGY STAR label, which is up to 4 times more efficient and uses 70 percent less energy than a standard model.
Before you commit to buying a tankless water heater, the primary drawbacks to know include: Higher upfront costs. Tankless water heaters are, on average, quite a bit more expensive to buy and install than tank water heaters. Access to fuel.
It's generally much cheaper to heat water using your central heating system, rather than using electricity with an immersion. The exception might be during the summer, when you have your central heating turned off, or if you have an old inefficient boiler.
On the cons side, the initial investment is higher, they require more space than traditional heaters, their efficiency can vary with climate, and regular maintenance is necessary to ensure optimal performance. How do the hybrid water heater pros and cons compare with traditional water heaters?
Energy Savings – Winner: Hybrid
This approach is far more energy-efficient than the traditional methods used by tankless water heaters, which rely on electricity or gas to generate heat.
Just like a tankless water heater, it is not running all the time, which makes for a real money saver when it comes to pulling electricity, so this is far more efficient than a standard water heater, but also keep in mind it still has a tank with an allowed amount of gallons of hot water so if your home is busy at a ...
Electric water heaters generally have lower running costs and lower emissions than gas water heaters. Hot water heat pumps are the most efficient option, requiring significantly less electricity to run than traditional electric water heater systems. Hot water cylinders can be installed inside or outside the home.
Additional Installation Costs
Tankless water heaters are much more complex than traditional hot water tanks. As a result, they require professional installation. If you're switching from a hot water tank to a tankless unit, you will likely need your gas lines rerouted, as well as a larger gas supply line.
Absolutely! In fact, tankless water heaters are becoming the standard for new home construction because of the energy efficiency.
For homeowners who want the most efficient heating system available, heat pumps are the best candidate. They work by capturing heat and moving it from place to place, removing it from your home to provide cooling in summer, and bringing in heat from the outdoors for warming in winter.

Heat pump water heaters: high efficiency and low consumption
These devices are a sustainable technology with low consumption, particularly suitable for use when there is a high demand for domestic hot water.
Reverse cycle air-conditioners provide convective heat and are the most energy-efficient heater and cooler of all types, irrespective of fuel source.
One type of water heater may use a fuel type more efficiently than another type of water heater. For example, an electric heat pump water heater typically is more energy efficient than an electric conventional storage water heater.
Continued advancements in materials and technologies are expected to make hot water cylinders even more energy-efficient and environmentally friendly. Innovations in storage capacities, quicker heating methods, and enhanced insulation will further contribute to reducing energy consumption and costs for consumers.
But for the vast majority of households, where a gas furnace provides the heat and the family is gone most of the day, hybrid tankless water heaters provide energy savings of about 15% compared with standard tankless water heaters, and up to 40% energy savings compared with a traditional tank heater.
It is important to keep in mind that electric tankless water heaters are generally 99%+ thermal efficient, whereas the efficiency rating of most gas tankless heaters, even the better quality units, range from about 80 to 85%.
Hybrid water heaters have a storage tank just like traditional standard tank water heaters. It is the way that the water is heated that makes them unique. Instead of creating heat, the hybrid water heater moves heat from the surrounding air into a converter that uses it to heat the water using a heat pump.
