The Twin Compact series flaunts powerful yet power-saving systems. Boasting a bigger heat capacity thanks to the use of two compressors, the Twin Compact models still achieve Energy-related product (ErP) efficiencies up to A++.
Each model brings its own unique advantage. Delivering high output for single-phase supply, the Standard Twin Compact range features one of the largest single-phase ground source heat pumps on the market (24kW). Providing temperatures up to 50°C, each model is the perfect match for low-flow heating distribution systems.
Next up is the Hybrid model. Using an efficient blend of high and low-temperature refrigerants, the Hybrid Twin Compact delivers the best of both low-flow space heating temperatures and domestic hot water up to 60°C.
Kensa’s High Temperature model produces heating and hot water to 60°C without the high emissions or maintenance you’d expect from gas and oil. A resilient range, the High Temperature Twin Compact takes on the greatest heating loads in applications with high and constant demands – from holiday lets to shower blocks.
The Three Phase Twin Compact model is ideal for the high heat demands of larger, three phase properties – offering an impressive capacity of up to 30kW.

The MCS-approved Twin Compact provides a generous, tax-free income from the RHI. Lasting over a 7-year period under the Domestic RHI, the incentive offers rewarding returns.
On top of funding, the low-maintenance and low-running-cost Twin Compact has no annual servicing requirements over its 20-year design life.
Besides the Twin Compact’s 5-year guarantee, end users and installers have access to Kensa’s technical support for the system’s lifetime. This includes anything from design guidance to post-installation support.See costs & payback
To balance demands in larger buildings, each Twin Compact model efficiently modulates between full and half heating loads. Not only does this reduce power consumption, but ultimately saves on heating bills.
To produce the desired temperatures at the highest efficiency, the Twin Compact features two temperature setpoints – one for heating and one for domestic hot water. No costly direct immersion heaters necessary.
