How much bigger do heat pump radiators need to be?

Air source heat pump radiators are often larger than radiators used with a traditional boiler because heat pumps normally operate at lower water temperatures. The exact size depends on the property's heat loss, insulation, heating requirements and system flow temperature. Some existing radiators may remain suitable, while others may need to be replaced with larger or higher-output models.

Is my house suitable for a heat pump?

Many homes, including older properties, can be suitable for an air source heat pump when the system is correctly designed. Suitability depends on insulation, room-by-room heat loss, radiator or underfloor-heating capacity, available outdoor space and the property's electrical supply.

Do you need planning permission for solar panels?

Most domestic roof-mounted solar panel installations in England are treated as permitted development when the relevant conditions are met. Additional consent may be required for listed buildings, scheduled monuments, some properties in conservation areas and certain ground-mounted installations. Property owners should consult their local planning authority when unsure.

How long do solar panels last?

Most solar panels have an expected operational life of approximately 25 to 30 years and may continue producing electricity beyond that period. Output generally reduces gradually over time, and manufacturer performance warranties commonly cover a significant part of the expected operating life.

Frequently asked questions

How does SGS Energy recommend the right renewable energy system?

The assessment and design process depends on the technology being considered, as each system has different requirements. For example, an air source heat pump requires a detailed heat loss assessment to determine the heating demand of the property, while a solar installation requires a system design based on factors such as roof space, orientation, shading and energy use.

Does SGS Energy work with both homes and businesses?

Yes. SGS Energy works with homeowners, landlords and organisations across a wide range of sectors, including education, care, agriculture, hospitality, manufacturing, leisure and community services. Every recommendation is shaped around the property, energy requirements and practical goals of the customer.
