Hi Pache (& villa1 if you can help also), why do I need to chemically treat my system each year & how do I do same? What is the reference to oxygenated water and as I presume it is "unhealthy", how do I seek to avoid this issue? Thanks
Because running your underfloor heating directly linked to solid fuel on an open vented heating system will cause furring,a process where the inner walls of your underfloor heating pipe become coated with a layer of oxide thus reducing the flow of water through the pipework and in severe,untreated cases,total blockage.
This results in an inefficient,lasy, system that cannot serve the purpose for which it was intended.
Underfloor heating should be pressurised for it to operate efficiently.
Locate the make of your underfloor system through any brand name visable on the system components or contacting your installer or supplier and ask this supplier/manafacturer does your system carry any warranty against corrosion whilst not connected to a pressurised system.
Please post these findings.
Meanwhile fmmc,you should not have any worries in relation to causing permenant damage to your underfloor system as the associated problems can be rectified.
This means in straight forward language the pipework that is your underfloor heating will need a good flushing out and re-treated with an addative every so often.This flushing takes place at your underfloor heating manifold .
