Example paperwork
An unvented cylinder service covers the safety valves, expansion vessel, discharge pipework and temperatures. This sample checklist shows what is checked and recorded, with fictitious details.
Every document above is a sample with fictitious details, shown so you know what to expect. None of them is a valid certificate, a completed inspection or a record for any real property.
An unvented cylinder stores hot water at mains pressure. The incoming pressure and flow, your household’s demand and the heat source all shape which cylinder size is right.
Tell us how many bathrooms are used at the same time and whether the cylinder is heated by a boiler, immersion heater or another source. Changing cylinder type can mean changes to pipework and controls.
The safety devices, expansion arrangements and discharge route are part of the system, not optional extras. Servicing follows the cylinder manufacturer’s instructions and the requirements that apply to your installation.
Water appearing at the tundish or discharge pipe, inconsistent hot water or pressure changes are worth reporting. Never cap a discharge pipe or adjust safety valves yourself.
Share the make, model, age if known and the symptoms. Access, cylinder dimensions and the existing connections all affect replacement options.
We’ll confirm the right competence and installation requirements for your particular system before any work is agreed.
The cylinder make and model, its heat source, any symptoms and the space available. Send your details and postcode and we’ll arrange the right visit.
Tell us the symptom and the cylinder model, and don’t block discharge pipework or adjust safety devices. The cause needs checking by someone competent for the system.
Yes. Send the make, model and any concerns with your message so we can arrange the right service.
Your postcode, the cylinder make and model if known, and whether you need installation, servicing or a repair. A photo sent through WhatsApp is always useful.
