Split system heat pumps

Air-to-water heat pump units that comprise an outdoor fan unit and indoor heating unit, taking up less external space and offering more installation flexibility.

System S

Dimplex’s System S split air-to-water heat pump, with modern inverter technology, provides domestic heating and hot water for new build detached and semi-detached properties. The outdoor unit is available in 6kW and 10kW output sizes and can be sited up to 15m from the property. The compact indoor unit is designed to be ‘plug and play’ and has a minimal footprint. System S is managed by a smart control system via the Dimplex Home App for easy control on the go.

Unintrusive

A pipe length of up to 15m between the units is possible, allowing the outdoor unit to be sited discreetly if external aesthetics need to be addressed.

Quiet operation

System S is designed for quiet operation, making it acoustically non-intrusive where the density of the development is a consideration.

High efficiency

Produces low-carbon hot water up to 60°C with a COP of up to 5 (A7/W35) and is capable of operating in external temperatures down to -25°C.

Space saving

Key features and components, including a 210l hot water cylinder, are integrated into the compact 595 x 600mm indoor unit, to aid installation, use and maintenance.

Product specification

Our split system heat pumps are often specified alongside mechanical ventilation and are available in two sizes.

A technical guide to the specification of heat pumps

This white paper aims to provide h a summary of the different considerations that will have an impact on the specification of heat pumps, heat pump-based systems and complementary technologies for large residential and mixed-use developments

We offer a wide range of CPD UK and CIBSE accredited CPDs covering different aspects of the design and specification of heat pumps. All CPDs can be delivered online or in person.
