• Extract heat from outside air and transfer it into the home. Ideal for retrofits if internal radiators or underfloor heating are adapted.
• Ductless mini-split systems
• Good for properties without existing ductwork or where room-by-room control is required.
• Less invasive installation and useful for extensions or flats that cannot accommodate larger external units.
• Hybrid systems
• Combine a heat pump with a conventional gas or oil boiler to handle peak demand.
• Particularly attractive for Kent homes with older radiators or where full heat pump replacement would require extensive emitter upgrades.
• Ground-source heat pumps
• High efficiency and stable output but require sufficient land for boreholes or horizontal loops.
• More suitable for rural Kent properties with space for groundworks.

Site assessment and load calculation: the crucial first step

A successful installation starts with a thorough site assessment and accurate heat loss calculation. This is not a one-size-fits-all task.

• Building survey
• Inspect insulation levels, window types, orientation, roof and wall construction, and existing heating distribution.
• Note conservation area restrictions, listed building status, or local planning constraints common across parts of Kent.
• Heat loss and load calculation
• Calculate how much heat each room needs at design outdoor temperatures typical for Kent winters.
• Use industry-standard methods to size the heat pump so it runs efficiently and delivers adequate flow temperatures.
• Electrical capacity and placement review
• Check the incoming electrical supply and consumer unit capacity to avoid surprises when connecting the heat pump.
• Determine the best location for the outdoor unit considering noise, planning rules, and service access.
• Distribution and emitter assessment
• Evaluate whether current radiators are sufficient or whether you will need larger emitters or underfloor heating to achieve comfortable low-temperature operation.
• Occupancy and usage patterns
• Discuss typical heating schedules, hot water needs, and priorities to recommend controls and system size that match your lifestyle.

Equipment sizing and selection

Correct sizing prevents short cycling, inefficiency, and comfort problems.

• Sizing principles
• Choose a heat pump that meets the building heat loss at the lowest expected temperature, not just average days.
• Consider oversizing slightly only where necessary for hot water demand or to offset poor insulation, but avoid gross oversizing which reduces efficiency.
• Selecting a model
• Factor in seasonal performance (Coefficient of Performance or COP), installed noise levels, defrost performance in colder days, and compatibility with your hot water cylinder or combi solutions.
• Manufacturer warranties and service networks are important for long term reliability in Kent.

Professional installation steps
