The Mighty Radiator, Herald of Winter

They have been idle all summer. Now, the first cold days prompt us to awaken those iron or steel thingamajigs, silent sentinels in every room, and see what happens. Now is their chance to show what they are worth. With some trepidation, we turn on the heating. We listen to noisy pipes, various hisses and gurgles, sure proof that the sleeping monster awakes. Tepid here! Tepid in here too! Warming up nicely! But things do not always go so smoothly. Sometimes, odd stains or unaccountable dampness are dire indications that something is not functioning correctly.

Elderly Radiators

The winter heating systems in older houses have been around for quite a while. Back in the day, hefty iron or steel radiators were built to last. Most of them, along with the venerable buildings they inhabit, have lasted admirably. But, even the most solid construction will show signs of wear and tear as one century gives way to another, whether it be a grand palace or a humble iron radiator. As buildings get restored and restructured, so radiators and heating systems can be effectively repaired and reset to function as good as new and No1PHD is the company to address the problem in the smoothest, fastest and most cost-effective way.

Finding the Fault

Generally, it is easy to see where the problem is on a leaky radiator. The leak can be clearly seen on a pipe-joint or valve, or there could be visible cracks in the radiator itself. Sometimes, the cause of dampness is not so evident. There are clues that you can follow to see where a leak may be: perhaps a damp spot on the carpet beneath the radiator or inexplicable dampness in the area or on the radiator itself. The presence of rust often indicates a crack or a pinhole.


Leaks in Iron Radiators

Leaks can occur in older cast iron hot water or steam radiators, notably:

  • where adjoining sections of cast iron are bolted together;
  • if the radiator is cracked;
  • there are rusty patches;
  • the join at the individual radiator sections display rust and leakage;
  • presence of splits, wetness or rust;
  • leaky valves and/or bleed valves;
  • piping fittings and radiator valves leak

If you notice any of the above, get in touch with No1PHD and your radiator problem will be dealt with promptly by the dedicated radiator repair team. Your radiator will be repaired and your heating will be back on again in record time.

Hidden Leaks

Sometimes, radiator issues can be mysterious. You just cannot figure out where that spot of water originates from. But there it is, a widening dot on the floor under the radiator. You have checked all over for cracks or crevices, or even tiny pinpoint specks that look suspicious. It is no easy job to bring to light those tantalising, almost invisible hidden plumbing leaks. Better call in the No1PHD repair experts, they know exactly where and how to look.

After noticing that the house was unusually cold, we found that the heating wasn’t coming on and that our hot water had also failed. We called the team at No 1 PHD who dispatched an engineer to investigate. After discovering that the culprit was a faulty boiler part, they ordered in a new part and got it fitted as quickly as possible. The guys were great, and we couldn’t be happier.

For days, we’ve noticed a foul smell coming from outside and a gurgling sound coming from one of the drains. Whenever it would rain, the area around it would flood slightly and take ages to drain. We tried buying drain unblockers, but none seemed effective. Eventually, we turned to No 1 PHD and were left wondering why we didn’t do this sooner.
