Gillan Heat & Flow provides professional air source heat pump installation across Edinburgh, Midlothian and East Lothian. We design and install systems around the heating requirements of suitable properties, considering the heat pump, hot water, controls and heat distribution as one complete system.
Installing a heat pump involves more than choosing an outdoor unit. The heating requirements of the property, hot water demand, radiators or underfloor heating and system controls all need to work together. We consider these elements when planning heat pump installations across Edinburgh and the Lothians.
Our Heat Pump System Design service includes consideration of the property's heating requirements and heat-loss calculations to help establish an appropriate air source heat pump solution.
Our Heat Pump & Underfloor Heating service brings together two areas of our specialist heating experience, allowing suitable wet underfloor heating systems to be designed and integrated with an air source heat pump.
Our Hot Water Cylinder Upgrades provide the cylinder and associated heating improvements required where the hot water system needs to be adapted as part of a heat pump installation.
Gillan Heat & Flow is a family-run plumbing and heating company based in Musselburgh, with more than 10 years of hands-on experience working with heating systems throughout Edinburgh and the surrounding areas.
Our practical air source heat pump experience includes Vaillant aroTHERM technology. A recent new-build project in Dunbar combined a Vaillant aroTHERM heat pump with wet underfloor heating across three floors, demonstrating our ability to work with the heat source, distribution system and controls as part of one installation.

Our experience designing and installing wet underfloor heating allows both parts of a low-temperature heating system to be considered together.
The performance of an air source heat pump depends on the wider heating system around it. Gillan Heat & Flow combines practical heat pump experience with knowledge of underfloor heating, radiators, cylinders and heating controls.
