Does the reservoir water heater press the booster pump (high marks)?
If insufficient pressure really, adding an automatic booster pump in the water inlet, is feasible. Home booster pump, a basic model, to sell the place to ask the next to know, generally 200 yuan or so, traffic 0.3-1.8, 90~150 watts on it. Do not buy too large, too much power, the water will also be too large, but the water heater will not be used.
60 liters of water storage should be able to drive two bathrooms at the same time bath! Water storage water heater generally does not need booster pump, as long as there is a little pressure, the water heater is filled with water, as long as the tap water can do. You can turn off the hot water valve and see only the amount of water in the cold water. If hot water is much smaller than cold water, it is the reason for the heater. Can you check the water mixer is normal, the one-way valve is installed in reverse.
The outlet water pressure of hot water is the same as that of cold water. The water heater is pushed by cold water to push out the hot water. (of heating). Installation location about 2 meters away from the ground, the impact of water pressure is not large, in rural areas, the installation position in more than two buildings will have an impact. In the city, the installation position is above four floor to affect the water pressure.
In addition, the water storage electric water heater has a safety valve is O.7MPa, before buying a booster pump, you can check the water inlet valve spring weakness, see the effect of water, barely even, then use it, do not buy.
