You don’t know what you don’t know.

Until you’re on a job…
Trying to tighten something awkward…
Or stuck using 3 different tools for something that should take 10 seconds.

That’s where most tools fall down.

They’re not designed from real problems — just copied and tweaked.

PlumbShark was built differently.

Designed from actual on-site frustrations.
Refined through real use.
Built to replace the small, repetitive jobs engineers deal with every day.

It’s not flashy.
But once you use it, you get it.

And that’s the point.

You don’t know what you’re missing…
Until you try it.

I used to hate bleeding old radiators.

The round-top valves… worn, slightly imperial… already chewed up from years of cheap keys slipping.

You’d try once → slip.
Try again → round it off.
Now you’re drilling it, forcing it… or worst case, changing the radiator entirely.

All because the tool doesn’t properly fit.

That’s the bit that never sat right with me.

So we built a key that actually does.

• Fits both modern and older imperial valves
• Grips damaged / rounded vents
• Longer handle = real leverage (not finger strength)
• Stainless steel, not soft brass that deforms

It’s now one of our best sellers, and the feedback is always the same:

“Saved me replacing the radiator.”

Sometimes good product design isn’t about innovation for the sake of it.

It’s just about solving a problem
properly.

Boiler prices have started rising again in 2026, and this time it’s not down to supply chain issues or inflation alone. Behind the increase is the Clean Heat Market Mechanism (CHMM), a policy that is now beginning to have a visible impact across the UK heating industry. While it’s designed to ac...

One of the common early spring call outs for engineers!

A call comes in: “The radiators are cold at the top again. I bled them last week and they’re already gurgling.” It’s a familiar pattern for many gas engineers this time of year. The customer expects a quick bleed and move on, but two or three visits later the same complaint returns. Persiste...

Hmmm thats one way to do it!

Mobile power flush machine idea 🤔What’s your thoughts?

A customer calls at 7am: “The boiler’s on the blink again – pressure’s dropped overnight and there’s no heating.” You’ve been there. By the time you arrive, they’ve already topped it up twice this month. No obvious puddles, no wet patches under the rads, yet the gauge keeps creeping ...

Most tools don’t solve the problem.

They just make it slightly less painful.

“Just Dose It” was built to actually fix one.

If you’ve ever tried dosing inhibitor into a heating system, you’ll know the drill:

• Spills everywhere

• Awkward angles

• Mess you didn’t need

So we stripped it back and asked a simple question:

How do you make this job clean, controlled, and repeatable—every time?

The result is a purpose-built dosing funnel that just works.

No overthinking.
No gimmicks.

Just a tool designed properly for the job.

That’s always been the Heatlab approach—designing tools that earn their place in the van.

And it’s working.

Over 100,000 units sold across the range, with products like this becoming go-to kit for engineers

If you’re a plumber or heating engineer, you’ll get it straight away.

If you’re a merchant or buyer—this is exactly the kind of product that moves.

Spring is here… and for us, that means one thing:

Bundles.

We’ve combined products commonly purchased together and put them into smart, practical spring/summer bundles — the kind that just make sense on the job.

✔️ Designed by a heating engineer
✔️ Built for real on-site problems
✔️ Products that naturally work better together

Whether it’s keeping things clean, catching water, or making valve changes easier — these bundles are about efficiency, not extras.

If you’re a merchant, plumber, or heating engineer:

👉 Jump on Amazon and try one for yourself
👉 Or drop us a message if you’re interested in stocking Heatlab

Simple products. Thought through properly.
