🇳🇴 Around 60–63% of homes in Norway now use heat pumps.

That is roughly 6 out of every 10 households.

So when people say “heat pumps don’t work in the cold”, Norway is a fairly strong answer.

The UK does have its own challenges.

We are often replacing traditional boilers connected to radiators, cylinders and wet central heating systems.

That means the design is everything.

✅ Accurate heat loss calculations
✅ Understanding the existing property
✅ Correct radiator and emitter sizing
✅ Correct flow temperatures
✅ Correct controls
✅ Correct commissioning

Heat pumps work.

But the experience and knowledge behind the design is what makes the difference.

At GI Developments, we don’t believe in simply replacing one heat source with another.

Every property is assessed individually to create a system that balances comfort, efficiency and installation practicality — achieving the best outcome with the minimum disruption possible.

We also believe in living with the technology we install.

We installed a heat pump in our own home and the biggest surprise wasn’t just the efficiency — it was the comfort.

Ask my family and they will tell you the same thing…

Our home feels more comfortable than it ever has before.

A correctly designed system delivers steady, consistent temperatures rather than the stop-start heating many people are used to.

And with the right design and some minor changes, heat pumps can also provide cooling through your home — something we’ve personally benefited from this summer.

For many homes, a Zero Disruption approach may be possible — retaining your existing radiators or underfloor heating while upgrading the way your home is heated.

Where a property would benefit from a more detailed retrofit approach, our own GI Developments design process is also available.

Same experienced team.
Same level of design.
Same quality of installation and aftercare.

The difference is simply choosing the route that best suits your home — not the route that suits us.

Let’s see what’s possible.

We’ve been a bit quiet on social media recently… mainly because we’ve been busy designing and installing low temperature heating systems across Hertfordshire and surrounding areas.
From air source heat pumps and underfloor heating to full system commissioning and optimisation, we focus on doing things properly from the start.

Not every heat pump needs a new concrete base.
On this installation in Tring, rather than redoing the base, we used adjustable anti-vibration feet to get the unit perfectly level.

✔ Less disruption for the customer
✔ Faster installation
✔ improved lifespan of unit

It’s small decisions like this that make a big difference to performance and longevity.

Working across Tring, Berkhamsted, Hemel Hempstead and surrounding areas.
