1. How a heat network and a station stay online
Smart heating covers heat-network monitoring, heat-exchange stations, and household-end control. Temperature, pressure, and flow go up over 4G. SimtoLink supplies heating companies with 4G SIMs, a data pool, a private APN, and an API into the heating dispatch platform.
2. The network, the station, the home, and a leak
Heat sources, the network, and the household end do not ask for the same freshness or the same reliability:
Heat-network monitoring and dispatch
Network sensors report temperature, pressure, and flow over 4G, for load forecasting, balancing, and fault warnings.
Heat-exchange stations and remote control
A station reports operating parameters over 4G, for remote control, energy-saving tuning, and equipment management.
Household control and billing
A household thermostatic valve reports room temperature and valve opening over 4G, for per-household control, heat billing, and complaint handling.
Leak detection and emergency response
Network monitoring reports an abnormal reading over 4G, for locating a leak, emergency dispatch, and a repair order.
3. What the heating link has to guarantee
- Temperature and pressure on the network: Key points keep reporting temperature and pressure. An abnormal reading alarms at once, so the heat supply stays safe.
- Remote heat-meter reading: Household heat meters are read over NB-IoT, which replaces a manual round, cuts cost, and avoids disputes over entering the home.
- The station, from a distance: Pumps and valves in the station can be started, stopped, and adjusted remotely, for weather compensation and heat on demand. That is where the energy saving shows up.
- Finding a leak: An abnormal pressure alarms and GIS places it, so the leak is found sooner and the repair is shorter.
- The dispatch platform: Tied into the heating dispatch platform, for a GIS view of the network, zone temperature control, and energy reports.
4. Station RTUs, heat meters, and network sensors
Network type, bandwidth, and power draw differ by device. Match the SIM to the device and the job:
| Use | Recommended network | Why it fits |
|---|---|---|
| Heat-exchange station RTU and control equipment | 4G | Remote monitoring, fault warnings, dispatch linkage |
| Heat meters | NB-IoT | Remote reading, infrequent reports, long battery life |
| Network monitoring sensors | NB-IoT/4G | Temperature and pressure, leak alarms, GIS location |
5. How much a heating device uses
A device typically uses about 50-200MB a month, mostly reporting. Pool by station, keep 20%-30% spare, and use a private APN so station data stays secure.
6. Security on heating data
The security level is medium. Sessions need TLS/SSL, a private APN, and an IP allowlist. SimtoLink completes real-name registration as part of the service.
7. Stations on 4G, household meters on NB-IoT
For smart heating, use 4G IoT SIMs on heat-exchange stations, heat meters, and remote-control terminals, and NB-IoT on household heat meters and other low-frequency collectors. The station has to watch temperature and pressure as they change. Heat meters are read in batches. The plan is built around 99.9% network availability, a data pool, and an API into the heating monitoring platform.
8. From a station retrofit to the rest of the network
Take the rollout through these stages:
Pick the SIM by station type. Check coverage on the heat network and at the station, set the APN and allowlist, and alert at 80% of the data allowance. SimtoLink covers the work from the survey through the wider network. Contact us for a plan sized to the system.
