Quick answer
A hybrid heating system in Perth pairs an air source heat pump with your existing gas, oil, or LPG boiler. The heat pump runs for most of the year and the boiler fires on cold days. It suits stone villas and rural cottages, subject to a survey.
Perth sits on the River Tay with a housing stock that includes historic stone buildings in the city centre, Victorian villas in Kinnoull and Bridgend, and rural cottages in the surrounding Perthshire countryside. Many city homes use gas boilers, while rural properties towards Crieff and Aberfeldy may be off-grid with oil or LPG. A hybrid heating system adds an air source heat pump alongside the existing boiler, cutting fuel use for most of the year while keeping the boiler for the coldest days.

A hybrid heating system in Perth pairs an air source heat pump with your existing gas, oil, or LPG boiler. The heat pump runs for most of the year and the boiler fires on cold days. It suits stone villas and rural cottages, subject to a survey.
Perth's older properties in the city centre and Kinnoull have solid stone walls with no cavity insulation. Victorian villas in Bridgend and Muirton have larger rooms with higher heat loss. Rural properties in Perthshire — towards Crieff, Aberfeldy, and Pitlochry — are often off-grid, heated by oil or LPG, where a hybrid system is particularly valuable because those fuels cost more per kWh than mains gas. Perth's winter temperatures typically reach -6 to -10 degrees, with colder pockets in the Highland fringes. The bivalent point is usually set around -2 to -5 degrees. The surrounding countryside offers ample space for outdoor unit siting on rural properties. The heat loss survey measures each room and accounts for the specific design outdoor temperature for your location.
Yes. The boiler runs existing radiators at higher temperatures on cold days. The survey measures heat loss through the stone walls and checks radiator output at lower flow temperatures.
Yes. Oil and LPG cost more per kWh than mains gas, so the heat pump delivers greater savings. The boiler remains as backup for cold days. No changes to oil tanks or LPG storage are needed.
Perth typically reaches -6 to -10 degrees in winter, with colder pockets in Highland fringes. The heat pump runs down to the bivalent point, then the boiler takes over.
We cover Perth city centre, Kinnoull, Bridgend, Muirton, Crieff, Aberfeldy, and surrounding areas. The surveyor confirms coverage when you enquire.
In most cases yes. The boiler can run them at higher temperatures on cold days. The survey checks each room and flags any radiators that need upgrading.
