Isolating hot water via combi boiler | Screwfi

2012-1-24 · I'd turn the boiler off anyway, but if the cold water supply to the boiler can be isolated, then the hot water from it is as well. I'd have a look around your flat and see if there is a stopcock though. Unusual for there not to be one. Usual, places are either in kitchen units, pantry's or bathrooms.

Best to Run Hot or Cold Water Supply to Boiler?

Best to Run Hot or Cold Water Supply to Boiler?

I agree about the softened water but if there's no softener, and no auto-feeder, I don't see a reason not to use the hot water. All that calcium and magnesium that gets deposited in the water heater precipitated out when the cold water was heated, so it's already been removed before it gets to the boiler.

Is a combi boiler safe with NO mains cold water

2012-12-16 · I couldn't find an isolation valve for the tap so had to turn off all the water via the main stopcock. The only worry is a plumber I rung said that without the cold water going to our combi boiler, the heat exchange could melt itself and cause a lot of damage so we had to turn our heating off.

Thermal Shock in Your Steam Boiler Will Ruin You

Thermal shock is caused by the return of cold water to a hot boiler. An example of this is when system piping in building cools down overnight, yet the boiler is kept hot, or when secondary pumps over pump primary pumps. Also, failing to bring a cold boiler up to temperature slowly could lead to thermal shock.

Cold Feedwater Effects on Steam Boilers | Stea

That is, the hotter the water, the less oxygen it will hold. The goal of any feedwater treatment program is to reduce the amount of oxygen in the feedwater so that as little as possible enters the boiler. Oxygen that enters the extreme temperature of the boiler quickly comes out of solution and attacks boiler tubes.

Hot water problem with combi boiler - any ideas? (27 Posts) Add message | Report. Cheers - like PigletJohn, I don't think a leak is causing the problem after all the cold water flow is minimum 12 ltrs a min and most the boiler could heat is 10 ltrs a min - so even if there is a leak, the boiler is still being fed more than enough water.
