Efficient all-electric water heating solution Improved performance from calorifiers

Stiebel Eltron has launched the SNE 5t ECO GB, a new all-electric water heating option for both domestic and commercial schemes. The SNE is claimed to be the first fully electronic small storage tank water heater available in the UK offering both efficiency and comfort with precise temperature selection, configurable timer programmes to suit every environment and user-friendly digital controls via a clear LCD interface. The product also includes an ECO mode to save energy, accompanied by a specific hygiene function that heats the water to 73oC for 30 minutes once a week to prevent the growth of bacteria. A thermostop function bolsters the product’s renewable credentials, preventing heat loss from mixer taps. The product also features anti-drip technology that reduces limescale deposits – saving water in the long run.

Mark McManus, managing director at Stiebel Eltron UK, said: “As the UK works towards the 2050 net zero target, with new legislation such as the Future Buildings Standard, we anticipate that renewable electric options will only grow in popularity. Embracing these heating methods will be a key element of the decarbonisation of our built environment.” Hamworthy Heating has improved its range of stainless steel calorifiers to now include models with a twin coil and five additional storage tanks. The new models offer better hot water performance and system security for large demand premises. The two coils in the new versions of the Halstock calorifier can be connected in series to improve the hot water performance as there is a larger surface area for heat transfer giving faster heat up times of 19-31 minutes and higher continuous output flows – up to 2,106 l/h from the largest model. Alternatively, the calorifiers can be connected to two different heat sources such as a solar collector array and a gas boiler. This means that end users can use free solar energy when available but also connect to a boiler for back up or top up to the heat supply. This allows greater control of the heat input and gives you the flexibility to choose how you heat your system. There are five calorifier sizes available from 300-965 litre with single and twin coil options. To complement the range and provide additional storage, and therefore system security, for high demand hot water applications, five buffer vessels/storage tanks have been added. These also range from 300-965 litre capacity.
