Hi, Just wondering if....................

the condensate in the drain pipe from my boiler freezes and the condensate backs up will this cause damage to the boiler.

Should I be trying to thaw the drain pipe and ensure this can not happen?

Do steamers normally have a "dripper" in the drain pipework? One of those little in-line wotsits where you can see the water dripping out? Or are they simply plumbed straight into the pipework?

All this talk about freezing condensate drains has made me certain that when I get my boiler done next year, I'm having mine either pumped or run internally to the bathroom basin drain. Hate the sight of badly run condensate drains snaking around the sides of houses anyway. They look 5h1t and in this weather its just stupidity. All the LA houses round here have them run like that.

if it gets cold enough the drain can freeze no matter what you do with the condensate run.

running it inside will give you far less chance of a frozen drain/condensate of course but it's not foolproofing it.
