Many houses still have normal central heating system and radiators. The central heating system heats the temperature of the water flowing through your radiators at around 70 to 80 degrees Celsius. However, when you have good insulation in your home the water flowing through your radiators only needs to be heated to 35 and 55 degrees Celsius.

You heat your home with radiators, trench heating or underfloor heating, and possibly with wall heating. The only difference is that the temperature of the water flowing through your radiators is lower than you’re used to. In a low-temperature heating system, the water flowing through your radiators or underfloor heating is between 35 and 55 degrees Celsius.

If you connect an energy‑use manager to it, you gain more insight into your energy consumption. This makes saving energy easier and more enjoyable.

Insulation","richBody":{"value":"If your home is well insulated, you can heat it effectively at a water temperature of about 35 to 55 degrees Celsius. Check whether your house has good insulation. Most houses built after 2000 have sufficient insulation, but for houses built before 2000 it depends on what measures have been done. A good insulated house has roof insulation, cavity wall insulation or wall insulation with a front wall or against the outside, floor or bottom insulation and HR++ or triple glazing.
"}},{"componentType":"paragraph","title":"Stap 2. Heat transfer","richBody":{"value":"Underfloor heating and wall heating are ideal for a low-temperature heating system. Thanks to their large surface areas, they give off adequate heat. But conventional radiators and trench heaters also do a good job, as long as they are large enough. Special radiators - known as low-temperature radiators - are also available. They incorporate fans to distribute the heat better. Finally, you can carry on using your current radiators with excellent results, as long as you add a fan coil unit.
