What is a buffer tank?
A buffer tank, also called a buffer vessel, is a type of battery storing excess energy in the form of hot water. Buffer tanks have multiple connection points, so they can take heat from different sources.That thermal energy is retained for up to days, depending on the type of buffer tank and the insulation of the tank.
Unlike a conventional water heater, a buffer tank provides hot water not only for sanitary purposes, but also for heating. The tank acts as an intermediate storage between the energy source and the central heating system. That makes buffer tanks the perfect way to improve the sustainability of our central heating systems.
Solar energy with a buffer tank
Buffer tanks can be heated with grid electricity, but also with solar energy, for example. Solar panels perform best during the day, but the peak hours for domestic hot water consumption are in the morning and evening. With a buffer tank you build up a stock of thermal energy. Energy that can be used at any time, even when the sun is not shining. This way you get a higher efficiency from your PV system, and you are always supplied with your hot water needs.
SEDS: the sustainable heating system with buffer tank
What is SEDS?
SEDS is a collective heating system that uses buffer tanks. Through smart, data-driven control of those buffer tanks, the heating system makes CO₂-neutral living possible, and all that at the lowest price on the market.
Ready for 100% renewable energy
SEDS can be connected to any possible energy source. Sources of today and the future. As a sole source, or in a hybrid setup. This makes the heating system not only more sustainable, but also completely future-proof. In combination with a PV installation, SEDS even reaches the lowest TCO on the market.
Buffer tank for storing green energy
SEDS converts self-generated energy centrally and then stores it in a buffer tank. By separating domestic hot water and heating, the water temperature in the buffer tank can be significantly reduced.
In typical collective boiler rooms, water is heated to 60-70°C all year round. Not at SEDS.
On the harshest winter days, SEDS already suffices with 40°C, in summertime even with 17 degrees. The seasonal temperature in the buffer tanks reduces energy consumption and increases energy efficiency.
Connection with heat pump
In order to get hot water from the tap, you obviously need a higher water temperature. That is why SEDS is equipped with a heat pump. This ensures that only the water that is actually used reaches a higher temperature.
That’s how SEDS makes CO₂-neutral living possible and comfortable.
