Rointe domestic hot water heaters are manufactured with high-quality components and include extended guarantees for your peace of mind.


Our new range of innovative water heaters are the ideal solutions to meet your domestic hot water needs. With advanced products including connected, digital, basic, compact and instant along with an air source heat pump. From special enamel to protect the interior tank to an exclusive thermal break system, we ensure their reliability under any circumstance. They include the latest advances in safety and consumption measurement.


Heat pumps provide both space and water heating, as well as cooling in one system. They work using a heat transfer process. They do not generate heat or convert electricity into thermal energy like conventional resistance heaters. Instead, they extract natural heat from one place and transfer it to another. Heat pumps use electricity to apply a little more energy to raise the temperature to the level required.


Whilst a heat pump will use an external energy source like electricity for the transfer process, the heat transfer can be three or four times larger than the electrical power consumed. This means that they have better energy efficiency than conventional electrical resistance heaters. For example, if a heat pump products 2.5 kilowatts of thermal energy, they actually use less than 1 kilowatt of electricity! This makes a heat pump system quite cheap to run and the most likely to reduce your carbon footprint. Learn more about heat pumps with our article here.


The Dalis Pro hot water heat pump is designed for high-efficiency production of domestic hot water. An air-source heat pump, the Dalis utilises “air to water” heat transfer technology ensuring the highest possible energy efficiency class (energy rating A+). This heat pump system is virtually silent and includes an enamelled steel tank that prevents water leakage, insulated by 50mm thick PU insulation to help reduce heat loss. It also includes submerged heating elements to heat water quickly and a magnesium anode to protect against limescale. Mandatory installation kit sold separately.
