🔧 A simple heating fault revealed much more than expected...

We were recently called out to a 14-year-old Worcester Greenstar 28i Junior in Petts Wood, BR5 because the heating wouldn't switch off.

What started as a relatively straightforward fault soon uncovered:

✅ A banned corrugated gas connection
✅ A split burner gasket
✅ A flat expansion vessel
✅ A leaking filling loop
✅ A damaged fan draught cap
✅ A partially blocked heat exchanger

The boiler was stripped down, repaired, cleaned, recommissioned and tested, leaving the customer with a safer and more reliable heating system.

It's a great example of why regular boiler servicing can identify hidden issues before they become expensive breakdowns.

L2 Ignition Lockout? Not always a simple reset...

We attended a breakdown in BR6 on an Ideal Logic boiler that had completely locked out. Further investigation revealed a damaged heat exchanger causing the issue.

The solution:
✅ New heat exchanger
✅ New sump
✅ New electrode set

A sizeable repair, but a much better outcome than a full boiler replacement. Customer now has heating and hot water restored. 🔥💪

🔧 Faulty Diverter Valve Replaced in Tonbridge 🔧

A customer in Tonbridge contacted us because every time they turned on the hot water, the radiators were heating up as well!

After diagnosing the fault on a Vaillant combination boiler, we found the diverter valve had failed, causing hot water to circulate through the heating system when it shouldn't.

✅ Fault diagnosed
✅ Diverter valve replaced
✅ Heating and hot water tested
✅ Boiler operating correctly again
✅ Happy customer

If your radiators are getting hot when you're only using hot water, or your hot water isn't performing as it should, a faulty diverter valve could be the cause.

A correctly working boiler means efficient heating, reliable hot water and lower energy waste. 👌🔥

⚠️ Boiler Safety Issue Resolved in Bexley (DA5)

Another customer left with a safe, fully operational heating system today in Bexley DA5.

During the inspection, we found the boiler was locking out due to spillages back inside the boiler. Further investigation revealed failed flue seals, which can compromise both safety and performance.

✅ Fault diagnosed
✅ New flue seals fitted
✅ Boiler tested and operating correctly
✅ Heating and hot water restored
✅ Customer left with a safe boiler

This is a great example of why regular servicing is so important. Small components such as flue seals can deteriorate over time and lead to much bigger problems if left unchecked.

If your boiler is showing fault codes, locking out, or hasn't been serviced recently, it's worth having it checked before it becomes a bigger issue.

🔥 Another heating system restored in Petts Wood! 🔥

This system was contaminated with murky brown sludge, restricting circulation and reducing heating efficiency.

✅ Full powerflush carried out
✅ Large amounts of sludge removed
✅ System water restored to a clean condition

If your radiators have cold spots, your boiler is noisy or your heating system is slow to warm up, a powerflush could be the solution.
