If you’re considering how to heat domestic hot water in your home, you’ve probably wondered: Is a domestic hot water heat pump or an electric boiler the better choice? The answer is clear – a DHW heat pump offers more advantages in terms of costs, comfort, and environmental impact.
An electric boiler that heats 200 litres of water daily uses around 3,400 kWh per year. In contrast, a DHW heat pump consumes only about 850 kWh annually, delivering up to 75% savings in energy consumption. Over 20 years, this can mean saving several thousand euros.
A DHW heat pump heats water via a heat exchanger, where heating surfaces are less hot than in an electric boiler. The water is heated more evenly and gradually, typically to around 55 °C, whereas electric boilers often heat water to 60 °C or more. Since limescale forms faster at higher temperatures, a heat pump significantly slows down deposits. This means less cleaning and a longer device lifespan – especially important in areas with harder water.
DHW heat pumps are designed for quick installation without complex modifications to existing plumbing. The device simply plugs into a standard electrical socket, and its connections allow for easy integration. You can also control it via an app, making it even more efficient and cost-effective.
A heat pump for domestic hot water not only heats efficiently but also extracts heat from the air during operation, passively cooling the space. This is particularly useful in pantries, utility rooms, or smaller spaces where a slight drop in temperature is welcome. With KRONO.FLEX ducts, you can even cool another room rather than the one where the heat pump is installed.
A heat pump for domestic hot water uses renewable heat from the air, significantly reducing CO₂ emissions. Compared to a boiler, a household of four can save up to 1,150 kg of CO₂ per year – equivalent to about 9,500 km of car travel. If powered by photovoltaics, hot water production is almost carbon-free.
If you want long-term cost savings, a smaller environmental footprint, and greater comfort, a DHW heat pump is undoubtedly the better choice over an electric boiler. Contact us today and discover the hot water solution of the future!
Yes. A domestic hot water heat pump uses up to 75% less energy than an electric boiler. This means significantly lower domestic hot water heating costs, a smaller environmental footprint, and greater comfort.
A heat pump for domestic hot water uses about 75% less energy than an electric boiler.
By using a DHW heat pump, a household of four can reduce CO₂ emissions by about 75% compared to an electric boiler. This is equivalent to avoiding emissions from around 9,500 km of car travel per year.
No. DHW heat pumps are designed for quick and easy installation without major changes to the existing system. The device plugs into a standard socket and can be smartly controlled via apps for greater efficiency.
Yes. A DHW heat pump heats water more evenly and at lower temperatures than an electric boiler, so less limescale forms. This means less cleaning is needed, and the device has a longer lifespan – especially important in areas with hard water.
