Hydronic Heating Systems Questions with
Correct Answers
How a hydronic system works?
A hydronic heating system is a forced hot-water heating system.
-Water carries the heat to the rooms and spaces in a house.
-Circulates in the system by gravity flow, or the water is forced into circulation by a pump. -
Circulates through distribution pipes to baseboard convectors or radiators.
-The boiler or water heater can use various fuels for heating the water, including No. 2 fuel
oil, natural gas, propane, coal, electricity, or a solid fuel.
-The radiators or baseboards are usually located within rooms and hallways at the outside
edge of the structure, along the exterior walls.
-There may be radiant panels in the floor or ceiling. -There may be one or more thermostats
installed in the house.
- The heat is released and distributed to the interior using natural convection.
What are three ways to describe hot-water heating systems using the following broad
categories?
-supply water temperature;
-the type of water circulation; and
-the arrangement of the distribution pipes.
Supply Water Temperature?
-A hot-water system that supplies hot water at temperatures higher than 250° F is referred to
as a high-temperature system. This type of system is usually installed in commercial and
industrial buildings.
, -A low-temperature system is one that supplies hot water at temperatures below 250° F, and
it's generally installed in residential and small buildings.
Type of Water Circulation?
-Every hot-water heating system circulates water either by a pump, as with a forced hot-water
heating system, or by gravity, as with a gravity hot-water heating system.
-Gravity hot-water heating systems rely on gravity.
-As such, hot water is lighter than cold water.
There are four types of distribution-pipe arrangements for a hot-water heating system.
What are they?
-one-pipe system;
-series-loop system;
-two-pipe direct-return system; and
-two-pipe reverse-return system.
What is a one pipe system?
-In a one-pipe system, there is one single pipe that carries the hot water throughout the
system. That single pipe carries the hot water to the radiators or baseboard convectors, and it
also carries the cool water back to the boiler or water-heating unit.
How are the radiators connected in a one pipe system?
-Each heat-emitting unit (radiator or baseboard) is connected to this main single pipe with
two smaller branch pipes, which are the feed line and the return line.
-One-pipe systems can be forced or gravity types.
The main advantage of a one pipe system?
