About Stack

Temporary heating when you need it most

A commercial boiler breakdown can disrupt day-to-day operations, particularly in buildings where reliable heating and hot water are essential.

Stack specialises in temporary boiler hire, backed by extensive commercial heating experience. We assess your existing heating system, the capacity required and the practical installation arrangements before recommending suitable equipment — then deliver it on a trailer, ready to connect.

Our aim is simple: to help you maintain essential heating services while your permanent system is being repaired or replaced.

On Every Stack Trailer

Three promises, built into every hire

The same three commitments you'll see on the side of our trailers — and what they mean for your building.

  1. Reliable equipment

    Quality temporary boiler plant, maintained to support reliable operation throughout your hire — from delivery through to collection.

  2. Expert support

    Backed by extensive commercial heating experience, with maintenance and breakdown assistance available for the whole hire period.

  3. Built for any environment

    Self-contained boiler plant in a road-towable trailer, positioned on site and connected to your existing system — schools, care homes, offices and industrial sites alike.

Why Choose Stack

Experienced people. Reliable equipment. Practical solutions.

We take the time to understand your building before recommending equipment — then stay with you for the whole hire.

  1. Commercial Heating Experience

    Our team brings extensive experience in commercial heating systems, helping customers understand their requirements and identify suitable temporary solutions.

  2. Quality, Well-Maintained Equipment

    We provide temporary boiler equipment maintained to support reliable operation throughout the hire period.

  3. Flexible Hire Periods

    With a minimum hire period of four weeks and options to extend, we can accommodate both shorter-term requirements and longer heating system repairs.

  4. Personal, Practical Service

    We take the time to understand your building, heating requirements and installation needs rather than offering a one-size-fits-all solution.

  5. Ongoing Support

    Our service doesn't end when your temporary boiler is installed. Maintenance and breakdown assistance are available throughout the hire period.

    Get in Touch

    Contact Stack and tell us about your heating breakdown, building and requirements.

  2. Step 02

    Site Assessment

    We'll assess your existing heating system, required boiler capacity, site access and potential installation arrangements.

  3. Step 03

    Your Quotation

    We'll prepare a quotation based on your equipment requirements, hire period and any additional services needed.
