hot water boilers are used to heat water in these systems
Hydronic systems are heating or cooling systems that transfer heat by
circulating a fluid through a closed system of pipes. First used in the
1700s by Russian engineers, they have evolved into eco-friendly and
fuel-efficient central heating mechanisms.
Usually, hot water boilers are used to heat water in these systems.
The hot water is disseminated through the dwelling in pipes which
radiate heat into the rooms using either steel or cast iron radiators or
baseboard convectors. Once the radiator is heated, the water is sent
back to the hot water boiler to be re-heated and the circulation loop
continues. These hot water boilers may also be used in radiant floor
heating systems.
Thus, hot water boilers are the most important component of hydronic
systems. They can be either gas-fired (using natural gas or propane) or
oil-fired (using liquid fuel). The advantage of gas-fired boilers over
their fuel-burning counterparts is that they require comparatively less
attention and maintenance. Gas-fired boilers are reliable and the only
problem they may pose is with their expansion tank or circulator pumps.
The main elements of a hot water boiler are aquastat, burners/valves, temperature and pressure monitor, air vent, expansion tank,flow monitor, circulator, drain valve and pressure relief valve. The function and importance of each element is: The relief valves alleviates water pressure when it increases within the system.
? The circulator is a pump that automatically circulates water through the system.
? The drain valve allows opening and draining
? The aquastat is a temperature regulation system.
