At the moment the bypass for my boiler is a 15mm gate valve.
The boiler is in the garage. 22mm pipe goes from it to the ceiling, runs along inside, then splits. 22mm heads off downstairs to heat the ground floor, the other half of the split reduces to 15mm to heat upstairs. The heating feeds a couple of rads before it reached the gate valve under the floor. Pipework carries on heat the bathroom and the other bedrooms.
All the rads bar the bathroom have TRVs fitted and I'm going to fit a TRV in the bathroom later in the year.
My question is, can I swap out the gate valve with an ABV at it's current location?
