The Adlår Dual Air Source Heat Pump - Affordable, Efficient Heating Designed For UK Homes
Because one heat pump shouldn’t have to do two jobs.
Heat Pump Specialists, Not Generalists
Adlår Castra does one thing — and does it properly.
Most companies install heat pumps alongside solar panels, batteries and everything else. We specialise exclusively in advanced heat pump systems and because we don’t divide our focus, we deliver a level of design precision and long-term performance others simply can’t match.
We are the UK’s only specialist in dual heat pump technology. By manufacturing and installing our own systems, we control every detail from heat loss calculations and design to grant management, installation and commissioning.
The result? A system engineered to remain efficient, reliable and fully supported for 15+ years.
And with our Warmth Guarantee, if your heating or hot water doesn’t perform as designed, we will return and resolve it — at no extra cost — until it does.
Cost, Carbon & Comfort
Switching from a traditional boiler to an Adlår Castra dual heat pump system is more than an upgrade. It’s a long-term investment in efficiency, sustainability and performance.
Many homeowners see a reduction in energy costs of up to 40% per year*, alongside a significant reduction in household carbon emissions.
But performance is about more than numbers. It’s about consistent warmth. Reliable hot water. Intelligent system control. With access to the £7,500 Boiler Upgrade Scheme grant, it is also one of the most financially accessible routes to long-term, low-carbon heating.

The Smarter, Greener Way to Heat Your Home
Adlår Castra’s dual heat pump system is engineered to deliver unmatched efficiency without compromising comfort. Your home remains consistently warm, your hot water dependable, and your energy consumption intelligently optimised.
Unlike traditional boilers and monobloc air source heat pumps, our dual heat pump system eliminates the performance trade-offs many homeowners experience. There is no choosing between heating and hot water and no drop in comfort during colder months. Just balanced, consistent performance all year round through higher Seasonal Coefficient of Performance (SCOP).
