About Warmflow
Who installers fit Warmflow for.
Warmflow is our default recommendation for rural and semi-rural oil-heated properties across NI. The Utility and Professional oil ranges are robust, well-serviced across Ulster, and sit at a fair price point. On gas, the Agentis range is worth considering against Baxi or entry-level Worcester.
5-year standard manufacturer warranty, extending to 7 years on registered installs. Parts and support are exceptional across NI given they're built 30 miles away.
