My parents have been so impressed with my evohome system when they visited that they have decided they want it for themselves. #
Currently they have a 25+ year old Oil Fired central heating system, no thermostat, no TRV's etc. DHW capability was added at a later date (approx 15yrs ago).
I'm trying to visualise what amendments will need to be made to the plumbing in order to fit Evohome effectively. Would just be looking at fitting the base pack and hot water pack to start with, no TRV zoning yet.
This is the current boiler and pipework setup (in the garage):

So, I was thinking a honeywell 3-port mid position valve, or two 2-port valves on the boiler outlet pipework. Would this work?
What about a boiler bypass, as there currently isn't one (no need). Would one strictly be required, as any time the boiler is on (commanded by boiler relay), one or both of the zone valves would be open? There is no pump over run that I know of.
Any advice appreciated
Thanks,
Gareth
