Our new range of domestic hot water (D.H.W.) electric unvented systems is now available. Choose from five solutions tailored to meet your hot water needs.


Rointe electric water heaters are manufactured with the highest quality components. From special enamel to protect the interior tank to the exclusive thermal break system, we ensure their reliability under any circumstance.


Manufactured with the latest advances in safety and consumption measurement, our electric hot water heaters are some of the most efficient on the market.

Quality guaranteed for up to 5 years.

We take the quality of our products one step further. That’s why we’re able to offer the longest guarantees on the market of up to 5 years on the interior tanks and 2 years guarantee on the electronic components.


The enamelled steel tank of our electric hot water heaters has exceptional properties like corrosion and water leak prevention.


It’s sealed using a state-of-the-art plasma welding method that eliminates any risk of leakage. It is the most stable welding process with the highest degree of safety since it uses a lower welding temperature that avoids the use of additional materials.


To protect the hot water tank from corrosion, its inner walls are covered with a layer of enamel vitrified 0.5 mm thickness.


It’s also manufactured with 3 cm thick polyurethane insulation to minimise heat loss, which is biodegradable and CFC-free, allowing us to help take care of our environment.



Save energy and prevent heat loss.

Rointe unvented electric water heaters have an exclusive thermal break system, which eliminates the thermal bridge between the tank and the external casing.


This prevents the flow of thermal energy between conductive materials, saving energy by preventing heat loss.


Thanks to this innovative design, we can reduce energy losses by up to 16%. 

Choosing your water heating capacity.

Choosing the right tank size or water heating capacity depends on a number of factors like number of users in the household, types of hot water use and the type of property your water heating system is to be installed in.


Due to a large number of hot water cylinders available on the market, choosing the right hot water tank capacity can be daunting. However, you can use our simple guide to Rointe hot water heaters below to choose the correct cylinder volume for you:

Safety for you and your family.

Our electric water heaters incorporate a protection system against legionella that raises the water temperature to 60ºC once a week, to destroy this dangerous bacteria.


Without this treatment, this and other harmful bacteria, which can cause infections and even allergic problems, appear when the water temperature is around 40ºC. 


This disinfection cycle eliminates 99.9% of these pathogens so you and your family can enjoy hot water that’s safe and reliable.


See the hot water heating progress.

The Rome and Siena unvented water heaters include an exclusive function so you can see the progress of water heating towards the user established target temperature.


This gives you more control over your consumption and can help to save energy.

Increase your hot water volume.

Installed at the hot water outlet of unvented water heaters, the thermostatic mixing valve allows mixing with cold water from the supply network. The resulting mixed water is transported at a lower temperature, saving energy by minimising heat loss through the pipework.


It increases the available hot water compared to the tank capacity and lowers the risk of scalding.

The increased amount of hot water available with respect to the capacity of the tank is known as the equivalent volume.


This equivalent volume represents the litres of water available at 39ºC, assuming the cold water temperature that enters the valve is 15ºC and the desired temperature is 73ºC.
