If you are looking for a heat pump for sanitary water 300 l, Therefore, before purchasing, it is worth checking more than just the price of the device.
In short: A 300-liter sanitary heat pump is particularly suitable for households with high water consumption. When choosing, check primarily the energy efficiency, the way the tank is filled, the possibility of connecting an additional energy source, management, and the ability to connect to a solar power plant.
What is the 300 l sanitary hot water heat pump?
A sanitary heat pump is a device designed to produce hot sanitary water. Unlike a conventional electric heater that directly heats the water with an electric heater, a heat pump uses the heat from the surrounding air for its operation.
Electric energy is needed primarily for the operation of the compressor, fan and controls. The heat pump thus enables the use of less electricity to produce the same amount of hot water than with direct electric heating.
When performing with 300-liter storage container The heat is stored in a larger amount of sanitary water, which is available to the user when they need it. This is especially important in households where a large amount of water is consumed in a short time, for example in the morning or evening.
How many people is a 300 l sanitary hot water heat pump suitable for?
There is no rule that applies when choosing a volume; a larger storage container is always better. What matters is that its size is adapted to the actual consumption of hot water – for orientation, approximately 50 to 80 liters of warm sanitary water per person per day.
For a four-member family, a sanitary heat pump with a volume of up to 300 liters is suitable.
Number of persons | Framework selection | When is a larger volume meaningful? |
1–2 people | smaller storage container | with excessive consumption or frequent use of large amounts of water |
3–4 people | 200–300 l | if the consumption is higher or there are more users at the same time |
4–6 people | 300 l or more | with higher daily consumption and more consecutive withdrawals |
In this case, the habits of the users must also be taken into account. A family that consumes a lot of water for showering, bathing, or other needs will need a larger reserve than a household with the same number of members, but with a lower consumption.
Why choose a 300-liter sanitary heat pump?
The main advantage of the 300-liter model is the greater available volume of hot water. This reduces the possibility of running out of ready-made sanitary water during multiple consecutive uses.
When choosing, it is not enough to just look at the volume. It is also important how efficiently the system uses the available heat and how it manages the water supply.
Greater supply of hot water
300 liters represents a considerable supply of ready-made sanitary water. This is an advantage especially for households with several members, where the need for hot water can arise almost simultaneously.
Lower electricity consumption
The heat pump extracts heat from the ambient air, so it does not use electricity in the same way as a conventional electric heater. An important fact to consider when comparing the devices is therefore COP, which relates the ratio between the heat obtained and the electrical energy consumed under certain measurement conditions.
More possibilities for using renewable energy
If the sanitary heat pump is connected to a solar power plant, the preparation of sanitary water can be adapted to the availability of electricity from the photovoltaic system. The SELTRON SAN device has a function designed for this. PV.
How does a heat pump for domestic hot water work?
The operation of the sanitary heat pump is based on a cooling circuit. The device extracts heat from the surrounding air and transfers it to the sanitary water using a coolant and a compressor.
- Extraction of heat from the air: The fan directs the air through the evaporator, from which heat is extracted.
- Coolant pairing: The coolant takes the heat from the air and converts it into a gaseous state.
- Compression: The compressor increases the pressure and temperature of the coolant.
- The transfer of heat leads to: The coolant transfers heat to the water in the reservoir.
- Repetition of the cycle: After the pressure is reduced, the coolant returns to the heat removal process.
The key to efficiency is therefore that the device does not generate all the heat directly from electricity, but transfers a large part of it from the surroundings.
SELTRON SAN 300: what does the 300-liter sanitary heat pump offer?
SELTRON SAN is a sanitary heat pump designed for efficient preparation of sanitary water. The model with a volume of 300 liters is designed for households with a higher need for hot water.
