How many people can a 200-liter hot water storage tank serve?

A 200-liter hot water storage tank is sufficient for a four-person household. You can expect to use approximately 40-50 liters of hot water per person per day for showering, bathing, and personal hygiene. With 200 liters, you have ample reserves, even if several people shower consecutively.

How long does it take for the storage tank to heat up?

The heating time depends on the heating output and the starting temperature. With a typical output of 2-3 kW, the storage tank needs about 2-3 hours to heat 200 liters of water from 15°C to 60°C. Modern models with higher output can heat up faster.

Does a hot water storage tank require regular maintenance?

Yes, maintenance every 1-2 years is recommended. This should include checking the magnesium anode (corrosion protection), safety valves, and insulation. Flushing the storage tank every 5 years removes deposits and maintains efficiency. With proper maintenance, the lifespan is 10-15 years.

Can I operate the hot water storage tank with photovoltaics?

Yes, electric water heaters can be perfectly combined with photovoltaics. You can use the solar power you generate yourself to heat the water and thus significantly reduce your electricity costs. Ideally, you should heat the water heater during the day when the PV system is producing the most electricity.

How much electricity does a 200L hot water storage tank consume?

The annual electricity consumption for a four-person household for hot water preparation is approximately 2.400–3.200 kWh. At an electricity price of 30 cents/kWh, this equates to roughly 720–960 euros per year. These costs can be significantly reduced by using self-generated solar power.
