What this sheet is for
Turn a boiler that keeps losing pressure into a dated pattern an engineer can act on. Every gauge reading, top-up and radiator bled goes on one record across the heating season.
Who it is for
Households with a sealed central heating system and a boiler with a pressure gauge, and landlords who get the call that the boiler keeps losing pressure.
How to use it
- Copy the pressure range from the boiler manual or gauge into the boxes at the top, with its unit.
- Read the gauge at the same point each time and write it down, noting whether the heating was on.
- Record every top-up from the filling loop, the reading you brought it back to and why it was needed.
- Log each radiator you bleed and check the gauge afterwards.
- Count the top-ups at the end of the season: a steady run of them is the evidence to show a heating engineer.

Printed under the title: Gauge readings through the heating season, every top-up from the filling loop and every radiator bled, so a slow loss of pressure shows up as a pattern you can show a heating engineer.
The range is on your boiler, not here. No pressure figure is printed: the right range is in your boiler's manual or marked on its gauge, and the reading rises as the system heats up. Bleeding radiators lowers the pressure, so check the gauge afterwards. Pressure that keeps falling points to a leak or a faulty part: call a heating engineer rather than keep refilling.

Questions
What should my boiler pressure be?
Whatever your boiler's manual or the marks on its gauge say. It differs between makes and models and rises as the water heats up, so a single printed figure would be wrong for many systems. Copy your own cold and hot range into the boxes at the top.
Why log top-ups at all?
Because a system that loses a little pressure over weeks can look fine on any single day. A dated list of top-ups shows how fast it is falling, which is what an engineer needs when looking for a leak or a faulty valve.
Should I bleed the radiators myself?
Many people do, following the boiler and radiator makers' instructions. If you are unsure, or the system is not one you know, ask a heating engineer. Either way, log it here and check the pressure afterwards, because bleeding lowers it.
