Good products matter. But so does the experience of buying them.

We hear this a lot from installers who work with us for the first time. They expect the cylinder to be right. What surprises them is how straightforward the whole process is.

No hard sell. No jargon for the sake of it. Just a team that enjoys what they do and wants to make sure you get exactly what you need.

Special brackets. Non-standard dimensions. A tight space that ruled out every catalogue option.

This is the kind of brief we thrive on. If your project needs something that doesn't exist off the shelf, we'll design and manufacture it from scratch. Every cylinder is built to order.

Complex briefs welcome.

Get in touch to see what custom-made solution we can make for you.

Tight space? Awkward dimensions? That's what we're here for.

Every cylinder we make is built to your specifications. If the standard sizes don't fit, we'll manufacture one that does. Custom heights, diameters, and connection positions as standard.

When you need a one-off cylinder at short notice, turnaround time matters.

We manufacture every cylinder in-house, which means we control the schedule from start to finish.

If your project has a tight deadline, talk to us. We'll give you an honest lead time.

Introducing the Pancake Buffer Vessel 🥞

We've built a buffer vessel for the installations where a standard one just won't fit.

Starting from just 200mm tall, the Pancake Buffer Vessel is designed to stack directly above or below a hot water cylinder, turning dead space into usable system volume.

Stainless steel, fully customisable connections, and a full-diameter baffle plate for stratification.

If you've ever had a heat pump job where ceiling height killed your buffer vessel plans, this is for you.
