The electric cylinder with dual elements, perfect for multiple supplies.
STIEBEL ELTRON’s SHZ range of DHW cylinders have dual heating elements so they can be connected to both a mains supply, and take a secondary supply from a renewable energy source such as Solar PV with battery storage. Extra savings can also be made when utilising off peak tariffs to maximize cheaper energy from the grid when available.
Solutions that help with compliance for planning in apartments and new builds are always in high demand and the SHZ product range meets this bill. In apartments with communal PV and battery systems, the SHZ means that a proportion of hot water for all tenants can come from a “free” renewable source, yet individual owners can set a timer and use the onboard boost button to store more energy for the times when they need it most. This removes anxiety about having enough water for guests, in holidays periods and means they are not reliant on the sun shining when their needs for hot water is high. It also helps developers hit their planning targets for efficiency and reduced carbon footprints.
The SHZ range of premium, wall-mountable cylinders are designed to take up minimal space and come in models from 30 to 150 litres. With temperatures up to 70°C they heat to a higher temperature than most electric cylinders allowing for very high volumes of mixed hot water. The 150 litre model, for example, can provide up to 321 litres of mixed water at 38 °C. Their high levels of insulation mean that they have very low standby losses and are energy saving.
An LED display provides a user-friendly interface and gives real time information on the current available quantity of DHW.
“SHZ are one of our favorite products for pairing with renewables for maximizing your return and consumption of self-generated electricity,” says John Felgate, Managing Director. “Our partnership with SOLARWATT and the integration of our products with their solar and battery storage systems means that customers are guaranteed a seamless operation between the different elements of their property’s smart tech.
“We also see SHZ units used for maintaining the secondary returns in heat pump installations. It’s a great solution for such circumstances too”
