FAQs
Frequently Asked Questions
What is the most common problem with boilers?
Boiler problems typically include low pressure, leaks, the thermostat, and the pilot light.
Is it worth repairing a boiler?
A boiler repair may be economically justifiable when the costs are significantly lower than the cost to replace the boiler, assuming the boiler is relatively new. If the boiler is old and troublesome, replacement may be more cost-effective. To discuss this further, reach out to C.S. Boxall.
How long is reasonable to wait for boiler repair?
Usually, waiting for a boiler repair should be within 24–48 hours, especially in winter when heating is paramount.
How to diagnose boiler problems?
Gauge the boiler problems according to the error codes on the screen (if it has one), listen to strange noises or drips and check the thermostat settings to be expected. If the problem is serious, give us a call.
What is the most common boiler fault?
The most common boiler fault is low boiler pressure, usually caused by leaks or bleeding radiators.
What is the biggest reason of boiler failure?
Causes for these boiler problems are mainly due to lack of regular maintenance, resulting in wear and tear, sediment build-up, and component failures. Contact C.S. Boxall to arrange maintenance.
