Wall mounted condensing central heating boiler

[hanser]

Hi
My daughter's boyfriend is going to leave his house unoccupied over the winter. I have advised total drain down of the water systems. The drain down of radiators etc is straightforward but is there anything that needs to be done to empty any residual water in the condensing boiler??
Your advice will be appreciated. I will not be able to acknowledge replies until late in the week so many thanks in advance.

why not just leave the system on a frost setting?

Hi Marcos

The house is in redec and most rads are off the wall etc. hence the need for a total drain down.

The boiler should have its own drain cock.

If you drain the central heating system does this not also drain the boiler?

Not always Waka. My boiler hangs on the garage wall. All the pipework runs under the upstairs floor with drops to the downstairs radiators (solid ground floor).

Draining the downstairs rad's will leave the boiler full of water, hence the MT cock(s) MM mentioned.
