The right checks for new and existing systems
Heat loss comes first
We assess winter demand before selecting air source equipment.
Distribution system reviewed
We check emitters, flow temperatures and hot-water provision.
Fault details used early
We use codes and symptoms to prepare for heat pump diagnostics.
Check the building before choosing a heat pump
An air source heat pump needs to match the property's heat loss and heating system. We arrange on-site surveys in Carlisle to assess insulation, radiators or underfloor heating, hot-water storage and a suitable outdoor unit position. We also consider the flow temperatures needed during cold weather. That information shapes the equipment size and any changes required inside the property. A heat pump chosen from floor area alone can miss important details, so we measure the heating requirement before proposing the system.
Prepare for installation or fault diagnosis
We also support oil boiler installation and existing heat pump servicing or repair in Carlisle. For installation enquiries, tell us about access, current heating and possible equipment positions. For a fault visit, provide the heat pump type, warning code, symptoms and any recent change in electricity use. We travel from our Hexham base for planned work, so accurate details help us arrange the right visit and avoid arriving prepared for a survey when the real problem is an unhappy circulation pump.
Frequently asked questions
What is assessed before an air source heat pump is designed?
We assess property heat loss, emitters, hot-water demand, controls, outdoor unit space and likely flow temperatures. These checks help us size the system and identify changes needed for dependable heating.
What should we send before a heat pump repair visit?
Provide the make and model if known, fault code, symptoms and when the problem began. Photos of the display and details of recent settings can also help us prepare for diagnosis.
Can you also replace an oil boiler at the property?
Yes. We install oil boilers and assess heating demand, fuel supply, tank condition, siting and flue needs. We can discuss this separately from renewable heating or as part of wider future planning.
