Amtrol is a manufacturer of expansion tanks and indirect water heaters used with radiant heat and boiler systems.
An expansion tank is used as a safety device to allow for expansion and contraction of water as it heats and cools. When a radiant floor heating system is not operating, the water in the system might be allowed to cool. When a thermostat requires heat for a room then the boiler heats the water to the required temperature.
