Air Source Heat Pump Water Pressure
The biggest advantage of air source water heaters different from hot gas
water heaters is that they can be started without water pressure, that is, as
long as there is water flow, they can be started. The starting of the gas water
heater is realized by the pressure of the water. Its basic working principle is
that cold water enters the water heater, flows through the water-gas linkage
valve, and at the same time pushes the DC power micro-switch to turn on the
power and start the fat flushing igniter. Open the gas delivery solenoid valve,
and continue to re-ignite automatically through the pulse igniter until the
ignition successfully enters the working state of the party. In this way, under
low pressure conditions (lower water pressure in higher-rise residences,
especially during peak water consumption), it may not start properly, and the
user turns on the faucet and only cold water flows out.
Do air source water heaters have water pressure requirements?
The general starting water pressure is more than 1.5 kg, and there are
also ultra-low water pressure 1.25 kg that can be started, but the comfort of
bathing has been greatly reduced if the water pressure is too low. If the
normal water pressure cannot be reached, a booster pump can be installed to
solve the pressure. The problem is that the water pressure can be increased by
3 times, and the water pressure of the family except for bathing can be
completely improved, which can be said to kill two birds with one stone.
What should I do if the water pressure of the air source water heater is
1. Check the water pressure first. If the local water pressure is low,
you can contact the local water company, or consider installing a booster pump
to increase the pressure.
2. If it is not the water pressure problem, check the gas filter and the
pressure reducing valve. If the air water heater has not been cleaned for a
long time, and the pipes are full of scale, the water pressure will become
smaller. In this case, you can find a special person to clean the fire channel
and Try the waterway.
3. Replacing the pressure reducing valve for the air water heater or
regularly cleaning the nozzle of the water heater can effectively increase the
4. If the above methods do not work, it is recommended to invite
professional maintenance personnel of air source water heaters to deal with it.
