Boiler question

[RonnieR]

I have a Vailant ecotec plus boiler. I want to drain the heating system and change all of the radiators. Trouble is it'll take me a while. Can I continue to use the hot water if I drain the heating system?

no you need to have water in the system easiest way would be to cut in some valves to allow nearest couple of rads to stay full

hi like steve said the boiler still needs to be pressurised but if u have a bypass fitted under the boiler u could just cap off the flow & return under that & let the bypass do the job of the heating circuit
