Keeping Families Warm Since 1968: The Warmflow Story

Every home has a story, and for nearly 60 years, we've quietly been part of those stories — Warmflow, a family-owned Northern Irish company has been designing and manufacturing their range of innovative and efficient home heating products since 1968.

From Lisburn to the Nation

Our 150,000 sq ft manufacturing facility in Lisburn, County Antrim uses the latest technology and cutting-edge manufacturing innovation to produce home heating products which offer our customers tangible benefits. From the UK & Ireland’s first and currently only AA rated oil boiler (saving homeowners up to 5ltrs of fuel per week), to the UK’s first air source heat pump with FULL remote control technology via a 4G SIM based platform.

Built Around the Installer and the Homeowner

Reliability, efficiency, ease of installation, and best in class after-sales customer support are key drivers for the business and everything we do is focused around ensuring we excel in these areas. Our dedicated customer support team members are all fully trained heating engineers who are at hand to support customers in whichever situation they require advice and support.

For homeowners, that heritage translates into something simple: peace of mind. A Warmflow boiler, cylinder or heat pump isn't just another appliance. It's backed by decades of proven innovation, performance and track record of reliability.

Looking Ahead

The heating industry is changing fast, with renewables, heat pumps and low-carbon fuels reshaping how we heat our homes. Our answer has been to keep doing what we've always done, investing in innovation. From our Zeno range of air source and ground source heat pumps to our Agentis range of HVO-ready oil boilers, while staying true to the values that got us here: quality, reliability, and a genuine commitment to the people who install and live with our products.
