Why choose our boiler range?

Their European reputations are outstanding, despite not currently being the most well known brands in the UK.  In our opinion they are the best on the market and expect their popularity to soar in the UK.

All boilers are manufactured to a very high standard, with high efficiency ratings which are increased further when paired with their smart controls. Their boiler ranges are also all opentherm compatible and weather compensated. 

These Manufacturers don't just want to sell you a boiler, they want to offer you a good service. This is why they formally approve installers and offer direct Manufacturer support. They offer remote access to your boiler to help identify problems even before you come across them! Minor issues can also be resolved remotely without the need for a call out.

At Online Boilers, we are proud to be Oxypod™ approved installers. We work in close partnership with the Oxypod™ team, carrying out testing and customer installations.

Oxypod™ is a multi-award winning compact de-aeration device with a European Patent. It’s unique egg-shape creates a natural phenomenon of water implosion which creates a vortex in the vertical pipe under the Oxypod™ resulting in the dissolved air from water in heating and cooling systems being forced upwards and out through the air-valve/vent at the top of the device. 

The benefits are numerous including, clean uncontaminated water, energy savings, reduced maintenance costs, extended boiler life, no more noise or cold spot on radiators. You fit Oxypod™ and forget it.
