Evenin' all.
I have a Pottertons Combi 80 (Combi 80 G.C. No. 47-393-03) in a single level flat. 4 rads with trvs. No room stat.
I am going away for the winter and am trying to decide how to avoid it all freezing while I'm away (without paying a fortune on gas). Specifically, whether to drain it down or not.
As far as I know, there isn't a drain valve. If there is, it's likely under floorboards and laminate flooring, which I'd rather not rip up on-spec. So if I can avoid draining it all down, that will save a lot of time and mess.
I notice in the Installation and Servicing instructions
Much appreciated

OK - so it sounds like the boiler itself will be protected. But will the water in the radiators (and the pipes leading to them) be similarly protected. i.e. when the frost stat protection kicks in, does it pump heated water around the CH circuit, or is the frost protection somehow restricted to just the boiler itself ?A frost thermostat is fitted which will bring the appliance on when the local temperature around the applicance falls below 5degC. The applicance will shut down when the temperature of the system water has been raised by approximately 10degC.
The frost thermostat will operate with the central heating switch in any position therefore when leaving the property in cold weather for extended periods, the boiler will be protected even when the switch is set to Off (Mid position).
Much appreciated
