The Oxyvent System does not affect the boiler as it operate within the normal delta T. In fact it does not interfere with the boiler in anyway. The flow rate through the boiler is also the same. The boiler will of course stay in full condensing mode 100% of its operating time. We only recommend that the temperature setting of the boiler be reduced to 60°C to save fuel.
The new 2°C delta T is only in the radiator circuit. This is what makes Oxyvent unique. The radiator circuit is isolated from the boilers circulation through a new hydraulic separation principle designed by Oxyvent.
What Temperature Should My Boiler Be Set At?
There seem to be a lot of confusion about what temperature should my boiler be set at. The correct temperature setting for a boiler with the Oxyvent Tank is 60°C. We supply a Clip on Pipe Thermometer with the Oxyvent Tank to remind the customer to keep the boiler set at 60°C so that their system will continue to operate efficiently.
By reduce the boiler temperature without the Oxyvent Tank you are sacrificing your thermal comfort. When the boiler temperature is reduced with Oxyvent due to the new 2°C delta T created you are in fact transforming the heat transfer of the heat emitters and therefore greatly increasing your thermal comfort. Oxyvent has the only System on the market that can isolates the Boilers cycle from the heat emitters. Oxyvent do not interfere with the boiler and the boilers flow rate is virtually the same. The boiler operate at its normal delta T while the heat emitters operate at a much lower delta T.
Condensing boilers will only condense efficiently when the water returning back to the boiler is below 55°C. Unfortunately with the current systems most boilers only condense at start up stage as the return temperature exceeds 55°C. Therefore we are losing out on the benefits that condensing boilers provide. When the Oxyvent Tank is installed the return temperature stay’s below 55°C keeping your modern condensing boiler in condensing mode. The Oxyvent Tank is the only product available that can keep a boiler in condensing mode without having to sacrifice your comfort level, and saving you money.
