We are looking at a couple of projects where we would like to be able to supplement/back-up an Ecodan with an immersion.

As far as I am aware the FTC2 supports this application, but we have not found a canister that we can mount a 3 or 6kw immersion in.

We have drawn up a design and priced it, but it is costly. Has anyone attempted this and if so how successful was it, and where did you source the canister from?

Cheers

Jon
