Systems and methods for preventing freeze damage to heating system pipes
View Patent ↗Systems and methods for preventing freeze damage to heating system pipes are provided. In some embodiments, systems for preventing freeze damage to heating system pipes that carry a liquid used to heat a heated space and that are exposed to freezing temperatures outside of the heated space are provided, the systems comprising: a hardware controller that causes the liquid to be circulated through the heating system pipes irrespective of the air temperature in the heated space.
1. A system for preventing freeze damage to heating system pipes that carry a liquid used to heat a heated space and that are exposed to freezing temperatures outside of the heated space, comprising:
a hardware controller configured to:
receive a time of day input;
determine a first specific duration for which the liquid is to be circulated through the heating system pipes based on a first value of the time of day input;
adjust the first specific duration to producing an adjusted first specific duration so that a temperature in the heated space does not exceed a thermostat set point;
cause the liquid to be circulated through the heating system pipes for the adjusted first specific duration;
determine a second specific duration for which the liquid is to be circulated through the heating system pipes based on a second value of the time of day input, wherein the second value is different from the first value and wherein the second specific duration is different from the first specific duration;
cause the liquid to be circulated through the heating system pipes for the second specific duration.
2. The system of claim 1 , wherein the hardware controller receives a manual adjustment of a duration during which liquid is caused to be circulated through the heating system pipes.
3. The system of claim 1 , wherein the hardware controller is integrated with a heating system thermostat.
4. The system of claim 1 , wherein the hardware controller controls a heating system using a relay.
5. A method for preventing freeze damage to heating system pipes that carry a liquid used to heat a heated space and that are exposed to freezing temperatures outside of the heated space, comprising:
receiving, using a hardware controller, a time of day input;
determining, using the hardware controller, a first specific duration for which the liquid is to be circulated through the heating system pipes based on a first value of the time of day input;
adjusting the first specific duration to producing an adjusted first specific duration so that a temperature in the heated space does not exceed a thermostat set point;
causing, using the hardware controller, the liquid to be circulated through the heating system pipes for the adjusted first specific duration;
determining, using the hardware controller, a second specific duration for which the liquid is to be circulated through the heating system pipes based on a second value of the time of day input, wherein the second value is different from the first value and wherein the second specific duration is different from the first specific duration;
causing, using the hardware controller, the liquid to be circulated through the heating system pipes for the second specific duration.
6. The method of claim 5 , further comprising receiving a manual adjustment of a duration during which liquid is caused to be circulated through the heating system pipes.
7. The method of claim 5 , wherein the hardware controller is integrated with a heating system thermostat.
8. The method of claim 5 , further comprising controlling a heating system using a relay.
