Hot water always ready with high-efficiency water heaters and storage tanks
The storage tank is the heart of any heating system: it stores the energy produced by the sun, the heat pump, or the boiler and makes it available when needed. A well-insulated tank reduces heat loss, limits the number of times the generator needs to start up, and ensures hot water is ready whenever it’s needed.
The Pleion Lineup: ULTRA, High-Performance, High-Competition
ULTRA is a domestic hot water storage tank with high-efficiency insulation, designed to minimize heat loss. The High-performance and High-competition lines cover a range of capacity, heat exchanger, and energy efficiency class requirements, from single-family homes to facilities with high demand. The range is rounded out by thermal storage modules for heat pumps.
How to Choose the Right Kettle
The main criteria are the daily hot water demand, the paired heat source—such as a solar thermal system, heat pump, boiler, or a combination of sources—the number and type of heat exchangers, and the available space in the boiler room. A properly sized storage tank prevents both hot water shortages and oversized tanks that waste energy.
Energy Storage and Solar Power Systems: A Perfect Match
Solar thermal systems produce energy when the sun is shining, not when you turn on the faucet. The storage tank bridges this time gap: it stores the heat generated during daylight hours and retains it for the evening and the following morning. The quality of the insulation determines how much of that energy actually reaches the point of use.
