Need your central heating looked at? Whether your radiators aren’t warming up, your system is making strange noises, or you want new radiators fitted throughout the house, HJZ Plumbing handles all central heating work across Hull and East Yorkshire. Please note: we’re not Gas Safe registered, so we don’t work on boilers or gas appliances, but we cover everything else in your heating system.

What We Cover

• Radiator repairs including fixing leaks, replacing valves, and bleeding radiators. See our radiator repair page for details.
• New radiator installations in rooms that don’t currently have heating
• Thermostatic radiator valve (TRV) fitting so you can control the temperature room by room
• System balancing when some radiators are hot and others are barely warm
• Power flushing to clear sludge and restore circulation. See our power flushing page.
• Heating pipework repairs, extensions, and re-routing
• Expansion vessel and pressure issues (on the water side, not gas)
• Cylinder repairs and replacements for hot water cylinders

What We Don’t Cover

We’re not Gas Safe registered, so we can’t work on:

• Boilers (servicing, repair, or installation)
• Gas pipes or gas appliances

If you need gas work done, we can recommend trusted Gas Safe engineers in the Hull area. And if you can smell gas, call the National Gas Emergency Service on 0800 111 999 immediately.

Common Questions

Some of my radiators are cold while others are hot. What’s wrong?

This is usually a balancing issue or air in the system. We can bleed the radiators and adjust the lock shield valves to make sure hot water flows evenly through all of them. If the problem is sludge, a power flush will sort it out.

Can you fit radiators in my extension?

Yes. We run new pipework from your existing central heating system and fit radiators in any room. We’ll check your boiler’s capacity first to make sure it can handle the extra load.
