Air to water & well water

    I'm just starting a new build but at an initial meeting with the builder he said that he was told by the air to water system supplier that water from a well (we plan to sink) would not be suitable for use in air to water heating system. I've yet to follow up with him for anymore details but has anyone heard anything similar?

    Well known issue so you will have to treat the well water before it is put into the pipework: its a once off plus top up

    Cheers. I googled it but had no luck.

    So is there much cost involved in the initial outlay/top up you mentioned?

    It depends on the type of A2W system that you choose, and possibly the quality of your well water.

    A buffer type system (and there are different types) might be fine, because you can treat the system water with inhibitor and this prevents the corrosion that is normally associated with well water. The system water becomes deoxygenated over time because there is little or no freshwater being introduced. Pex based underfloor with stainless manifolds and you have drastically reduced the potential for problems.

    A system that uses an external plate heat exchanger to transfer the heat energy to your freshwater (it's the freshwater that causes the problems) means that at worst you may have to change a plate heat exchanger occasionally - but that is not nearly has hard or expensive as any other component.

    No matter what heating system you choose you will run into similar problems! Some water treatments play hell with Stainless keep that in mind!
