None. Probably the home was built for forced air and converted to boiler/baseboard heating.
Well when I hear the word "Fired" used in reference to a boiler, it is used to describe the type of fuel used to heat the boiler (to fire it) such as a "Coal fired" or "Gas fired"
A condenser boiler has a primary and a secondary heat exchanger. Fuel that is used to simply warm up water can be sent to the secondary heat exchanger and reused. This is a substantially more efficient use of energy.
the apparatus ( Marcet Boiler ) consist a cylinder surrounded with isolated substance in it electrically heated boiler which is used to heat up water and to measure the both of the temperature and pressure, & it contains thermometer & barometer & safety valve .
You will find it in any mechanical engineering heat transfer book
A hot water heater is the storage tank of water that is responsible for the supply of hot water to the many fixtures in the house, such as showers and sinks. It does NOT supply heat for the home itself. There are two basic types of water heaters, one that runs on gas or some other fuel and one that runs on electric. A boiler on the other hand IS responsible for the heating of a home itself. Water or steam in a boiler reach much higher temperatures than the water in a hot water tank and therefore its used for heating and not drinking water or potable water. In a steam system for heating, pipes run throughout the house from the boiler carrying steam that eventually gives off its heat at the many radiators. In a hydronic system for heat, smaller pipes carry hot water to various baseboards around the house that release the heat using circulator pumps to push the water through and back to the boiler.
The purpose of a biomass boiler is to generate heat by burning or converting mass to energy. It does this in an efficient and environmentally friendly manner.
The purpose is what it was without a HVAC system ... to make heat !
An industrial boiler heats up the whole building and provides a lot more heat than a standard boiler it is designed to be used in places like power stations.
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.
waste heat recovery boiler
The purpose of a heater is to heat up the room when it is cold; by using gas
The purpose of a cold heat soldering iron is to fuse electronic components, pipes and other metal materials together by melting solder as a connector which hardens as it cools. You can learn how a cold heat soldering iron works and it's different purpose at the HowStuffWorks website.
what are the 3 ways to transferred heat into a boiler
The boiler will heat up the water that comes out of the tap or is used in the radiators. Also the kettle will heat up cold water to make a cup of coffee or tea
You can't because it is non potable water. That is why there is a Watts 9D check valve on your boiler. You need a heat exchange water tank to do what you want.
To protect it against predators, the heat, and cold.
Heat flux is the primary performance paramater in boiler performance. Heat flux can be affected by many factors espacially by boiler tube fouling ( or exchange surfaces) that will considerably reduce heat exchange.
