Once the condensate pipe is thawed and you have successfully restarted your boiler, you can lag the pipe with waterproof and weatherproof lagging to help prevent it re-freezing. As a temporary measure, it may help to turn the boiler thermostat (not the room thermostat) to maximum and run the boiler in 'continuous' mode, turning the room

Boiler flues are essential to building a safe central heating system. When a boiler works, it produces carbon dioxide, carbon monoxide, nitrous oxide and water vapour as by-products. A boiler flue pipe installed to regulatory standards will transport noxious gases safely outside the home, where they won't be inhaled.

The condensing process is achieved by passing the piped hot flue gases through the cooler return water flowing back into the boiler. Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less.

Condensing boilers are designed to not only use the heat generated by the combustion process, but also the heat of water vapour content. Older, non-condensing models could waste up to 50 per cent of the heat produced due to gasses escaping up the flue. In new appliances, the energy in these gases is captured and used to preheat the cold water that enters the boiler.
