How do I re-pressurise the boiler?

If you have no heat or hot water, the most common reason is that the pressure has dropped on the boiler.  For a  central heating system to work properly the water pressure should remain constant. Modern combination boilers are pressurised systems and water will enter the system from the mains cold water supply through a manual filling device, known as a ‘filling loop’. Adding water via the filling loop to the system after a drop of pressure will help bring your system to the correct pressure again and the pressure gauge will then increase.  This should be at 1.5 bar.  Refer to the operating instruction leaflet for the make and model of the boiler for instructions of how to do this.  If you do not have an instruction booklet, these can often be downloaded from the internet.

    Just moved in to a property managed by Stuarts. The team are incredibly helpful and my move in experience has gone very smoothly. From viewing to completing every meet was on time, great service and very professional.

    Stuarts offer the most efficient service I have experienced by far, but with an added personal touch. They are a close team and this produces excellent results in terms of clear communication and process. They are also just warm and kind individuals who go out of their way to make your life easier. I'll always be grateful for them taking the stress out of my move. I would never go anywhere else!

    We moved to U.K in 2015 and it was our first rented property. The whole process was carried out in friendly and smooth way. We rented the property for more than 2 yrs and we were facilitated and dealt in very effective, efficient and professional way. Unfortunately land lord decided to sale the property so we have to find a new place. The move out process is as smooth and clearly communicated as the move in was. We would certainly recommend Stuart properties and would love to seek their assistance in future. Special thanks to Colin and his team who were always there for us. Warm personal regards from our family!
