🔥 MagnaCleanse Flush Results – See the Difference 🔥

Those colours don’t lie 👀
What you’re seeing here is a thermal image showing how efficiently radiators heat up after a MagnaCleanse® flush by

Over time, sludge, rust and debris build up inside radiators and pipework. This restricts water flow, causes cold spots, and forces your boiler to work harder for longer. A MagnaCleanse flush removes that hidden build-up using powerful magnetic filtration and specialist chemicals.

✅ Radiators heat up faster
✅ Even heat from top to bottom
✅ Improved system efficiency
✅ Reduced boiler run time
✅ Lower energy waste

This is a premium form of PowerFlush and is ideal if your radiators are slow to heat, uneven in temperature, or if you’re looking to improve overall heating performance — especially before or after a boiler installation.

📞 Contact us today to book a professional MagnaCleanse central heating flush and get your system running at its best.

Our recent customer had an older Vaillant boiler with frequent faults and ongoing repair issues. After multiple breakdowns, replacing the boiler became the more reliable long-term solution.

We installed a Worcester 1000 and upgraded the gas pipework to 22mm to ensure correct gas flow and performance.

✔️ Press-fit gas installation
✔️ Full system power flush
✔️ Clean, efficient, and reliable heating

A properly installed boiler with a fully cleaned system means no more faults, better efficiency, and peace of mind going forward.

🧯Gas Leak Found? Rerunning the Pipe Can Be the Safest Solution for your property!

Recently, we attended a property where a gas leak was identified within the block. The existing gas pipe was buried beneath the concrete floor, making traditional repair both disruptive and expensive.

After assessing the situation, we recommended the most practical and cost-effective solution:
• The old underground gas pipe was safely capped
• A new gas pipe was installed externally, surface-mounted on the wall
• The new run connects directly from the gas meter to the property
• Fully compliant with current gas safety regulations

This approach avoids breaking up concrete floors, reduces labour time, and most importantly eliminates the risk associated with hidden gas pipework.

Why wall-mounted gas pipe reruns are often the best option
• Faster and less invasive than floor excavation
• Easier to inspect and maintain in the future
• Safer than concealed pipework
• More cost-effective long-term

If you’ve been told you have a gas leak, or you’re dealing with old or inaccessible gas pipework, rerunning the pipe externally is often the safest and most sensible solution.

At DL Gas & Maintenance, we specialise in:
• Gas leak detection and repair
• Gas pipe rerouting and upgrades
• Safe isolation and capping of old pipework
• Residential and landlord gas works

A lot of people hear the phrase “bleed your radiators” and genuinely have no idea what it means — I was the same before working in the heating industry. If the top of your radiator is cold or your heating just isn’t performing well, there’s a good chance you’ve got trapped air inside the system.

Air stops hot water from circulating properly, which means your radiators will never reach full temperature. Luckily, bleeding them is easy and only takes a few minutes.

All you need is a radiator key.
Place it on the bleed valve (usually at the top corner), turn it slowly, and let the trapped air escape. Keep a tissue underneath to catch any spray. As soon as you see water coming out, close the valve again and that’s the radiator bled.

This simple step helps your home heat more evenly and can make your boiler run more efficiently too. But if you’ve bled your radiators and you still have cold spots, patchy heat, or radiators that never warm up fully, the problem may be sludge and debris inside the system. In that case, your heating may need a power flush to restore proper flow.

If you’re unsure, give us a call. Our engineers can check your heating system and advise whether a power flush is required.

We cover E3 Bow, E14 Canary Wharf & Poplar, E15 Stratford & Mile End, E16 Canning Town, SE10 Greenwich, SE9 Eltham, SE3 Kidbrook & Blackheath, SE13 Lewisham, SE18 Woolwich, DA1 Dartford, DA16 Welling, DA15 Sidcup, DA9 Greenhithe, DA10 Ebbsfleet Valley, DA12 Gravesend

At DL Gas & Maintenance, we don’t charge a call-out fee — so there’s no extra cost for us to come out to you.

To secure your booking, we simply take a payment of 100 pounds for the first hour.

If your issue is a small job and can be resolved within the hour, there’s no additional charge.

In addition, after diagnosing the problem if the engineer finds that we need to source parts and further work is required which will require a second visit, that 100 pounds for the diagnostics will be deducted from the total cost.

Our goal is to keep things clear, fair, and transparent, thus you always know exactly what to expect.

Thank you for choosing DL Gas & Maintenance, where we take pride in delivering reliable, high-quality service to keep your home safe and comfortable.
