PBT Installations exclusively install Stiebel Eltron heat pumps. It’s not the only brand on the market, but after years of installing heat pumps across the UK, it’s the one we’ve chosen to build our business around — and we think that choice matters as much as who installs it.

Why we chose Stiebel Eltron

There are plenty of cheaper heat pumps on the market, and we could sell them. We don’t, because we’ve seen too many budget systems underperform once winter actually arrives — struggling to hit temperature, running inefficiently, or simply not lasting. Stiebel Eltron has been manufacturing heat pumps for over 40 years, engineered for the kind of cold, damp climate the UK and continental Europe both deal with, not adapted from a warm-climate air conditioning unit. That German engineering background shows up in day-to-day performance: consistent output even when it’s well below freezing outside, rather than the system quietly struggling and falling back on immersion heaters.

The Stiebel Eltron range we install

  • WPL air source heat pumps — our most commonly installed range, suited to the majority of UK homes, from retrofits to new builds
  • WPF ground source heat pumps — for properties with the land or borehole access to take advantage of ground source’s higher, more stable efficiency, particularly larger homes, barns and conversions

Both ranges include cooling-capable models, meaning some properties don’t need separate air conditioning at all — the same system heats in winter and cools in summer. We’ll size and specify the right model for your property during a proper heat loss assessment, rather than defaulting to a one-size-fits-most unit.

What this means for you

Choosing us as your installer means choosing a team that works with one heat pump manufacturer in real depth, rather than a generalist installer who fits whatever’s cheapest that month. We know this range’s quirks, its controls, and how to get the best performance out of it in a Gloucestershire property specifically — solid-wall Victorian terraces, Cotswold stone cottages, and new-build estates alike.

Frequently Asked Questions

Why only one brand rather than offering a choice?

Depth over breadth. We’d rather be genuinely expert in one high-quality range than average across several. If Stiebel Eltron genuinely isn’t right for your property, we’ll tell you honestly rather than force a fit.

Is Stiebel Eltron more expensive than other heat pump brands?

Often positioned above budget brands, yes — but the gap narrows once you factor in the Boiler Upgrade Scheme grant (up to £7,500) and the running-cost efficiency over the system’s lifetime. We’ll talk through real numbers for your property.

Do you install both air source and ground source Stiebel Eltron systems?

Yes — which range suits you depends on your property, land, and hot water demand, and we’ll advise honestly on which fits rather than pushing one over the other.
