When should I request a boiler diagnosis?
For recurring faults, pressure changes, unexplained error codes or before authorising a significant repair.
Can every part be replaced immediately?
No. The exact reference, availability and underlying cause must first be confirmed.
How often does a boiler need maintenance?
Frequency depends on fuel, capacity and region. We first check which rules apply to your installation.
Can I order the part myself?
An incorrect reference may be unsuitable or unsafe. Compatibility and the cause should be checked first.
What boiler output do I need?
It depends on heat loss, insulation, the property and hot-water demand. Floor area alone is not enough.
Can I still request a rich-gas conversion?
This page no longer offers a commercial conversion service. For a current fault, use the diagnostics or repair service.
Does pressure loss always mean a leak?
Not necessarily. The expansion vessel, safety valve or other components may also be involved.
Do you repair instantaneous water heaters?
Provide the brand, model and energy source so that we can confirm the possible service.
