    it should be, which could increase your energy bills.

• • What happens if a boiler has low pressure?
    If your boiler has low pressure, it could be the result of your water pressure being too low.
    The optimum water pressure should be between one and two bars atmospheric pressure, which you could
    obtain the reading on the water pressure indicator on your boiler.

• • What happens if my boiler pressure is too high?
    If your boiler pressure is too high, it could lead to severe damages to your boiler and even your home.

    you may need a new boiler installed.

• • What should boiler pressure be when the heating is on?

    manual if you’re unsure about your boiler pressure.

• • Does bleeding radiators affect boiler pressure?

• Do you turn boiler off when bleeding radiators?
  Radiators are hot so it is essential to turn your boiler off before bleeding the radiators.
  You need to cool down your radiators first before you begin the bleeding. A radiator key is typically
  used to turn the valve anticlockwise to release some pressure.
