>> I always have up till now. What is wrong with doing it?
Heat Soak. When the boiler cuts off flame, it keeps the pump going to keep water flow through the heat exchanger to prevent heat soak from warping it. The pump shuts off after about 5 minutes.
If there is no flow, this wont work. If all TRVs are shut there is no flow.
