If the boiler is up to temperature, then the problem is with the pump. If the boiler is cold you should call a pro, as there is no way to diagnose it from here with out more info.
No, furnaces are forced air heat. Boilers are hot water heat.
Better heat transfer than natural convection. When compared to water or liquid cooled heat exchangers, the argument could be made that air is a cheaper cooling medium.
Forced convection are used in car radiators, cooling towers, air cooled heat exchangers etc.
A boiler heats water to a safe heating temperature, often 180 degrees or so, and when a thermostat calls for heat, circulating pumps move the water from the boiler to the radiators where it heats the air surrounding the radiant surface, causing localized convective heating as well as some amount of conductive and radiant heat transfer. others have said: Stratification HEAT goes to the cold.
Convection.
Get a plumber to trace your cold water lines to find out where the heat is getting into the line.
No, furnaces are forced air heat. Boilers are hot water heat.
No, most landlords do not include utilities (heat, electricity, water) in the rent.
The problem encountered by Apollo 13 was an oxygen tank explosion that caused a loss of electrical power, cabin heat, and potable water, putting the crew in danger. This forced the mission to be aborted and the crew to use the lunar module as a lifeboat to survive their return to Earth.
The water is not circulating through the heater core or you have a control problem. If the heater is putting out heat then it is probably a control problem. If no heat then - water pump out, low on coolant, or maybe the therostat is stuck open.
Water scarcity is a problem around the world because only two percent of water on earth is fresh water. Also more of that water is being polluted.
They don't
One thing no one likes about winter is being forced to pay massive heating bills. One of the biggest parts of any heating bill is what it costs to heat water. Here is one tip you can use to help alleviate that problem. Once every three months, go to your water heater and drain about a quart of water from it. This will remove some of the sediment that has built up in the heater. This sediment can stop heat from transferring as well as it should. By taking this step, you will allow it to heat the water in your home much more efficiently.
The cold water supply enters the tank at the bottom near the burner. Heat rises, as does hot water. The hot water supply is piped out from the top.
Better heat transfer than natural convection. When compared to water or liquid cooled heat exchangers, the argument could be made that air is a cheaper cooling medium.
The formula to find the specific heat of water ( Q ) is: ( Q = mc\Delta T ), where (m) is the mass of the water, (c) is the specific heat capacity of water, and ( \Delta T ) is the change in temperature of the water.
I had the same problem with my 98 jimmy I repalaced the water pump have had heat since.
