Hi
I have purchased all the evohome equipment which finally is going to be installed in the next few weeks. However I'm considering making the setup opentherm.
Currently I have a two port valve and I'm setup as figure 4. With a opentherm setup a 3 port valve is recommended for true hot water priority. Can you please post a diagram of this setup?
A heated towl rail is not an option, we will have to fit an ABV. To confirm will this be in addition to the ABV built into the boiler.
Thanks
Iain
