Help Needed — Heat Pump Water Pressure Errors

[Alik]

Dear Members

I need some help from you guys. I am from Cork, Ireland and we recently replaced our Oil Fired Boiler with Air Source Heat Pump but every now and then the Heat Pump stops working with the error either “water pressure too low” or water pressure too high”. We contacted the manufacturer and they told that the heat pump needs a constant 1.5 Bar pressure to work properly and it has sensors which shuts it automatically if the pressure goes below 1 bar or above 2 bar for safety reasons.

Could someone advise me if there is any automatic pressure valve / loop system available to keep the pressure at or around 1.5 Bar so we don’t have to adjust it manually every now and then. If so could you please provide some link to buy online.

I would highly appreciate your kind help in this regard.


Best Regards
Alik
