Have you checked the return temperature?

By monitoring the return temperature, you can check that the energy you are paying for is being used correctly. A rule of thumb is that there should be a difference between supply and return of about 10 degrees at +- 0 degrees.

If the difference is lower, you pay for energy you don't use and, depending on your district heating supplier, you may be penalised if your return temperature is too high.

Here are some things to check if you have poor cooling.

• Is the correct setting, position, speed and lift height of the circulation pump for the heating system? For example, if the speed of the circulation pump is too high, the water will not have time to cool down.
• Are the radiator thermostats working? If the thermostats are broken and/or there is a high flow through the valves, there will be less cooling in the system, resulting in a high return temperature.
• Remember to have a separate return sensor for the radiator circuit and to regularly reference the flow and return sensors so that they give the correct values. Also check that the sensors are intact, that the sensors are correctly positioned and that the sensors are firmly attached!
