The detail that mattered
A small split.
A closer look.
When a boiler stops doing its job, getting the heating back matters. So does knowing that the repair has received the attention it needs.
At this Builth Wells property, SwiftHeat UK Group Ltd replaced the air pressure switch on an existing Navien LCB 700 oil boiler. During the work, we found that the hose connected to the switch had deteriorated and split.
That hose needed attention too. We replaced both components before moving on to testing and commissioning. It was a small detail within the appliance, but a clear part of completing the repair properly.
From repair to return to service
The work behind
the warmth.
Attention to the connection
A new air pressure switch was fitted, together with a replacement for the split hose identified during the work. Both replacements formed part of this repair.
Checks before completion
With the replacement parts in place, the boiler was tested, commissioned and returned to operation. Heating operation was then checked following the repair.
A clear handover
The work was documented and explained to the customer. A separate 12-month workmanship guarantee was provided, bringing the repair and its aftercare together.
