Common Problems You Might Face After A New Boiler Installation
Let’s run through a few typical post-installation issues and what they might mean for your system.
1. Low Pressure Can Disrupt Heating
Low pressure is one of the most common boiler problems after installation. It can cause your boiler to shut off or stop heating radiators effectively.
Check your boiler’s pressure gauge – it should be between 1 and 2 bars when cold. Anything under that likely means a top-up is needed using the filling loop.
Repeated pressure loss may point to a leak or air in the system – call a heating engineer if unsure.
2. Error Codes Indicate Where The Problem Lies
Many modern boilers will display error codes that indicate exactly what’s gone wrong – such as sensor faults, ignition failures, or circulation issues.
Not sure what your boiler’s trying to tell you? No worries – our Streatham boiler installation experts are happy to help decode it.
3. No Heat Or Hot Water Is A Red Flag
If you’re experiencing no heat or hot water following installation, it might be a simple thermostat issue – or something more serious like a blocked filter or failing valve.
Try resetting your system first. If that doesn’t help, a professional inspection will ensure the problem is resolved correctly.
4. Leaks Signal A Serious Concern
A leak under or near your boiler is never normal. It could stem from faulty seals, poor pipe connections, or manufacturing faults.
If you spot a leak, turn off the boiler immediately and contact our Streatham boiler repair team for an urgent fix.
4. Noisy Pipes Or Radiators Often Mean Air Or Debris
Gurgling, banging, or clunking sounds from your system? These might indicate:
- Trapped air
- Iron oxide buildup (common in older systems)
- Blocked filters
This is a good time to consider a power flush or radiator cleaning and maintenance.
Tips To Prevent Boiler Issues After Installation
A few simple habits and checks can keep your new boiler running smoothly and efficiently.
1. Book A Post-Installation Check-Up
At Happy Dog Plumbing and Heating, we offer a complimentary follow-up inspection for every boiler installation project in Streatham. It’s our way of ensuring everything is working as it should.
2. Bleed Your Radiators
Cold spots or noisy pipes? You likely need to bleed your radiators. This releases trapped air and improves heat circulation – simple but effective.
3. Keep Filters Clean
A clogged filter can cause a range of issues, from error codes to complete shutdowns. We recommend checking filters regularly – especially if you live in an area with older pipework.
4. Protect External Pipes From Freezing
During winter, condensate pipes outside your home can freeze, leading to no heat. Insulating these pipes or relocating them indoors can prevent this common issue.
5. Know Your Error Codes
Familiarise yourself with your boiler’s manual so you can quickly recognise what any error codes mean. That way, you can act quickly if something does go wrong.
When To Call A Heating Engineer
While some minor issues can be resolved at home, others are best left to professionals. Call our expert team if you:

FAQs
1. Why is my new boiler losing pressure after installation?
It’s usually due to air being released from the system or a leak in the pipework. Keep an eye on it and call a heating engineer if the issue continues.
2. Are boiler error codes something I can ignore?
No – error codes are your boiler’s way of saying something’s wrong. Some may be minor, but recurring codes need professional inspection.
3. What should I do if my boiler starts leaking?
Switch off the boiler immediately and call an engineer. A leak might damage other parts of your heating system or your home.
4. How long does it take a new boiler to settle in?
Most systems work well straight away, but a few adjustments may be needed within the first few weeks.
5. Do I need to clean my system after installation?
If your system is older, we recommend a flush or at least filter cleaning. Find more tips in our radiator cleaning and maintenance guide.
