Heating advice

Advice | 09-09-2022

Read more about which type of heating is available, what the energy-saving options are and what else you should pay attention to.

Why is it important to heat sufficiently?

The temperature must be high enough to avoid condensation. Condensation occurs with increased humidity, often due to a lack of ventilation. If these hydrogen particles come into contact with cold windows and walls, it will condense. This means that these particles become liquid and adhere to the surface. A lack of fresh air can cause mould, wood rot, peeling wallpaper and stucco. Condensation can also occur when warm air and cold air touch each other, such as when taking a shower. In this case, just open the window. 

What is the minimum and maximum temperature for heating?

We recommend that you set your temperature between 18-22 degrees. Depending on your wallet and comfort requirements. In general, a comfortable temperature in your home is 21 degrees.

How do I save cheaply and quickly?

We advise you to better insulate your house, now tackle your thermal bridges or weak links in the floors, roof or facade of your home. Alternatives to better retain the heat in your house are also possible by using thicker curtains, secondary windows, use insulating glass foil, draft strips under doors. Your temperature at 18 degrees means that it is very cool during the day, even with a sweater on. Count on the fact that a log can provide some extra comfort. So now dry enough wood and ensure that there is sufficient production.

Type of heating

  • Central heating with traditional radiators
  • Underfloor heating
  • Electric heating
  • Heat pump

Alternative ways of heating also exist, of course, such as hydrogen, heat networks / residual heat from industry, wood stoves and more.

Central heating with traditional radiators

In a traditional radiator, hot water is supplied and heated by your central heating boiler. The heating elements of your radiators give off the heat to the room. A smart thermostat can then be a solution to only use energy when necessary, it only sends a signal to the boiler that it should be warmer if necessary. Another alternative is smart radiator valves, which can be installed per radiator and controlled individually.

Underfloor heating

Underfloor heating consists of all loops that lie under your floor and through which hot water passes. Each loop can be controlled separately with a valve that can communicate with your home automation, for example Loxone Smart Home. This way you can indicate exactly which room, at certain times, should be a comfortable temperature. This way you save on your energy consumption with home automation. Electric underfloor heating also exists, but we will not discuss it further in this article. 

It is important with underfloor heating that the difference between day and night is no more than 2-3 degrees. This is because it takes a lot of energy to heat up this difference again, because this happens slowly at a slightly lower temperature. Unlike a traditional radiator. Finally, we recommend that you do not set too great differences per room for open spaces, or spaces that are often open. Please note, underfloor heating is only an efficient form of heating if you have set it up correctly. The idea behind this is that it is more efficient to have a gas boiler burn continuously on a low heat than on full and then completely off again. And so on.

Underfloor heating is usually only installed during a major renovation or new construction, and that is not only because it has to be installed under your floor, but also because the house must be reasonably insulated. We advise you to integrate this into your home automation because you can save even more, enjoy higher comfort and your home is worth more.

Electric heating

A.      Electric fan heater

An electric fan can ventilate, and blow warm air into the room. The heat comes from a filament and the fan blows this heat where you want it to go. This means they don’t have to be very large devices. 

Ceramic stoves heat with a ceramic plate instead of a filament, but still work with a fan.

Advantages and disadvantages of an electric fan heater versus a convector heater:

+ A little more compact

+ Large heat range

– Makes a lot of noise

Partly because of the noise, we only recommend this in rooms where people do not live primary. For example, a garage or handyman where you get to work.

B. Electric radiators

The name electric convector heater or radiator means the same thing. The heating element (filament) draws in cold air from below and the warm air rises. This air cools down again and so the process repeats. In this way you can quickly heat a room. Many electric radiators can set a minimum temperature or control it at any time through a WiFi connection. 

Coverage of electric radiators (indication), depending on the insulation and height;
PowerHeated floor area
1500W12-18 m2
2000W16-22 m2
2500W 20-26 m2
3000W24-32 m2

We recommend these heaters for all reasonably insulated interior spaces that are not too large.

Overheating protection electric heater

Since these devices can get quite hot, you should not take any risks with them in your home. Many electric convector heaters have this feature, especially our recommended selection.

Electric heating bathroom

Damp areas and electricity means you need to be extra careful. Sometimes a stove or heater is sold for the bathroom but without the proper certification. Therefore always look in the manual where you can use it! To be suitable for a bathroom, an electric heater must be splash-proof.

To reflect this, manufacturers use the IP certification. This consists of 2 numbers, the first indicating the extent to which the device can withstand dust and the second number indicates the extent to which the device can withstand moisture.

IP certificaatUitleg
IP66Dustproof and water resistant
IP67Dustproof and immersion-proof
IP68Dustproof and waterproof

Note with IP certification: Always read what the manufacturer of the brand writes about it in the manual and make sure that the device has a CE mark. We have already done that work for all products on our platform: everything meets at least the strictest legal requirements.

C.       Infrared heating

An infrared panel gives off radiant heat, ie horizontal or vertical heat waves that heat the environment. Ideal if you want to heat locally, such as a small space. Sometimes there is a built-in thermostat and there are bathroom models where you can hang towels. Please note, count on 15 minutes before it is completely warm. Also possible to operate via an app.

We recommend these types of products for your outdoor patio heating. 

D.       Heat pump

There are heat pumps that extract cooling or heating from the ground and heat pumps that extract this from the outside air. The latter is very interesting for your swimming pool, because as soon as it gets warmer outside, this heat pump converts this heat (air to water) into heating for your swimming pool.

For a geothermal heat pump, ground drilling must be done and your house must be well insulated. This system provides cooling in the summer and heating in the winter. Do not forget that the heat pump itself still uses (a lot of) electrical energy to get your house at a pleasant temperature. The advantage is that the heat source itself costs nothing. Electric and hybrid heat pumps are available. We advise you to involve an installation company and not to do this yourself.

Check whether you subsidize your heat pump, you can do this on the website of the national government.
