Most customers judge a new boiler by whether the shower ran hot that evening. The installation's real quality is written elsewhere: in the details around the appliance, the readings taken at commissioning, and the paperwork that either exists or does not. All of it is readable by a layperson who knows where to look.
R M Burn & Son Plumbing & Heating Engineers installs boilers in Portishead, and this is the inspection we would encourage any customer to make of any installer's work, ours included.
The details beside the boiler
Look below and beside the appliance. A magnetic system filter on the return pipe says the installer protected the heat exchanger from the system's debris; its absence on a full installation is a corner already cut. Isolation valves on the connections say future service visits will be simple. Pipework clipped straight, joints clean, and a condensate run with proper fall to a sensible termination say the installer cared when nobody was watching.
The condensate pipe deserves particular attention in any winter climate: external runs should be insulated and adequately sized, because the freezing condensate pipe remains the most common cause of an avoidable cold-snap breakdown.
- Magnetic filter on the return: system protection done.
- Isolation valves: future servicing made easy.
- Condensate insulated and falling properly: January survived.
Signs of a clean system underneath
A new boiler on an old system should have been preceded by a proper flush and finished with inhibitor, and there are honest tells: the installer can show you the filter's first catch at the follow-up, radiators heat evenly top to bottom, and the system water in any bleed runs clear rather than black.
R M Burn & Son Plumbing & Heating Engineers treats the flush, filter and inhibitor as inseparable from the installation, because connecting new equipment to dirty water is how warranties get tested early. Ask what was done to the system, not just to the wall.
- Ask what flushing the system received before connection.
- Even radiator heat and clear bleed water are the tells.
- Inhibitor dosed and noted for the next service.
The paperwork that must exist
A compliant installation produces documents without being asked: the commissioning checklist completed with real readings, the appliance registered so the warranty clock starts, and the installation notified so the paperwork exists when the house sells. Gaps here are not admin quirks; they are the visible edge of invisible shortcuts.
Keep it all in one folder with the user guide. Future engineers, buyers' solicitors and warranty claims all speak fluent paperwork, and the household that can produce it saves money at every one of those moments.
The handover worth insisting on
Ten minutes before the van leaves: shown the filling loop and how to top up pressure, shown the condensate route and what to do if it freezes, controls explained until you could set a weekend away yourself, and the first service date agreed rather than left vague.
Then the two questions that reveal everything: what did you find when you opened the old system, and what should we watch in the first month? Installers who answer specifically did the job specifically.

Questions customers ask
What should be fitted alongside a new boiler?
A magnetic filter on the return, isolation valves on the connections, a properly routed condensate, and inhibitor in a flushed system. Together they are the difference between an appliance swap and an installation.
What paperwork should a boiler installation produce?
A completed commissioning record with readings, warranty registration, and notification of the installation. All three should arrive without chasing.
How soon after installation should the first service happen?
Within twelve months, and warranties typically require it documented. Booking it at handover is the easiest way to make sure the anniversary is kept.
Filter, condensate, clean system, real paperwork, proper handover: five checks any householder can make, and together they predict the next decade better than any brochure.
