High Efficiency Technology

Save up to an extra 10% on your energy bill in comparison to other A-rated boilers

The Eco Flow RF is an incredibly efficient boiler and you can save up to 40% on your energy bills in comparison to an older, inefficient boiler. With advanced technology, the boiler condenses 100% of the time in both heating mode and hot water, meaning you save money on your bills. It is the only boiler on the market with this advanced functionality.

Smart Phone Control

Control your heating via an app on your smart phone

Be in charge of how much energy you are using in the home, by controlling your boiler from your phone or via the programable thermostat. With inbuilt connectivity to a smart phone, the Flow boiler can be controlled wherever you are.

What’s more, if a potential fault was to arise, this can be picked up remotely by your installer and fixed as soon as possible, providing you with minimum, if any at all downtime.

Ultimate Reliability

Have full trust in your boilers performance

Uniquely, the Flow Eco RF comprises only 12 parts – meaning there are less things to go wrong. With each component designed to the highest quality, in 20 years there has never been a single mechanical failure of the primary heat exchanger.

With the highest quality vacuum insulation, the boiler is also extremely quiet, with minimal noise.

Guaranteed Hot Water

100% guaranteed hot water all year round

Even if the water pressure was to drop as low as 0.2 bar, you are still guaranteed to have hot water due to the boilers exceptional hot water rate. As the hot water is served in a separate circuit in the boiler, even if the pump was to fail, which is extremely unlikely, you will still have hot water.
