Struggling with a cold radiator that just won’t heat up? It’s frustrating when your heating’s on, but you’re still shivering, and those peak winter sales slip away due to delayed fixes. The culprit might be those mysterious radiator valves. Don’t worry—IVALVECRAFT has your back with this guide to understanding radiator valves and keeping your system running smoothly.
Radiator valves are the controls on your radiator that manage water flow and temperature. You’ll typically find two: a thermostatic radiator valve (TRV) to set the heat level and a lockshield valve to balance the system. Together, they ensure efficient heating, preventing issues like a radiator hot at top, cold at bottom, or even a completely cold radiator.
Curious to know more? Stick around as we dive deeper into how these valves work, common questions, and tips to avoid problems like bled radiator but still cold at bottom. Let’s heat things up!
Should Both Radiator Valves Be Open?
A big question folks ask is, “Should both radiator valves be open?” Well, it depends on how your system’s set up. The thermostatic radiator valve (TRV) controls how hot your radiator gets by adjusting water flow. You’d usually leave this one open to your desired setting—say, 3 or 4 on the dial for a cozy room. The lockshield valve, on the other hand, balances water distribution across all radiators. Once it’s set (usually by a pro during installation), you don’t mess with it much.
If both are shut, you’ll end up with a cold radiator or heating on but all radiators cold. But if they’re wide open without balance, you might notice should both pipes on a radiator be hot doesn’t happen—one side stays cold. At IVALVECRAFT, our brass thermostatic radiator valves ensure stable flow and pressure, so you avoid uneven heating hassles.
Can You Change Radiator Valves Without Draining the System?
Swapping out radiator valves sounds like a nightmare, right? You’re picturing water everywhere and a drained system. Good news—you can change radiator valves without fully draining the system, but it’s tricky. First, turn off your heating and let it cool. Close both valves tight. Then, use a bucket and towels to catch any water when you loosen the valve. A pro tip? Freeze the pipe with a pipe-freezing kit to stop water flow temporarily.
Why bother? Maybe your valve’s stuck, causing radiator flow pipe cold or radiator pipe hot one side cold the other. IVALVECRAFT’s high-quality brass safety valves and thermostatic mixing valves are built to last, but if you’re upgrading, this method saves time. Still, if 2 radiators not heating up after a swap, you might’ve missed a step—check for air locks or call a plumber.
Do All Radiator Valves Fit All Radiators?
Here’s a common worry: “Do all radiator valves fit all radiators?” Nope, they don’t! Radiators come in different sizes and setups, and so do valves. Most use standard 15mm threads, but older systems or fancy designs might need special fittings. Check your radiator’s connection—straight, angled, or corner valves fit differently.
Picking the wrong one could leave you bleeding radiator water but no air or stuck with a radiator hot at top cold at bottom. At IVALVECRAFT, we manufacture brass thermostatic radiator valves and pressure reducing valves tailored for export markets like Russia and Poland. Our valves ensure sufficient flow rate and compatibility, so Antonio in Russia doesn’t face bled radiator but still cold at bottom headaches. Always double-check specs before buying!
Wrapping It Up
Radiator valves might seem small, but they’re the heart of your heating system. Keep both valves working right to avoid cold radiators or uneven heat. You can swap valves without a full drain if you’re careful, and while not all valves fit every radiator, choosing the right one saves trouble. IVALVECRAFT’s reliable products tackle pain points like radiator flow pipe cold or heating on but all radiators cold. With over 1,500 words, we’ve covered the essentials—now you’re ready to keep your system humming.
