Assortment of panel radiators

Do you want to replace your current radiators? The easiest solution is to buy radiators again. The plumbing is already there of course, which makes installing new radiators all the more easy. Haceka's radiators have a high yield because of the use of narrow and closely placed water channels. This makes it possible to place more convection slats on the panels. These are welded directly onto each water channel, resulting in an enhanced heat emission. Are you looking for a modern look? The Cover panels by Haceka give your radiator an sleek look.

European standard
EN442 is a European standard which has standardized the calculation for heat emission of a radiator. This means that you as a consumer can compare the wattage of tested radiators according to EN442. According to EN442 the wattage is determined by the water supply with a temperature of 75°C and a return temperature of 65°C at a room temperature of 20°C. A radiator can only be compared to another one if they are tested according to this principle. This cannot be done if the radiator was tested according to another standard. A manufacturer can, for instance, increase the supply temperature to 90°C. The wattage of that radiator would therefore appear higher. In this case a consumer would get false information. Haceka considers quality of paramount importance. In addition to meeting European quality standards, every radiator is tested for leakage before it is allowed to leave the factory.

You can simply mount the radiator with the supplied mounting sets. In addition, you will need: radiator taps (normal or thermostatically controlled) and possibly teflon tape or plumbing hemp. If pipes need to be re-routed, please purchase the necessary materials to do this.
Calculate beforehand how many Watts are needed to heat the room and what how much heating you need in the room. This way you can avoid any disappointments later on.
It is recommended to heat larger spaces with several radiators, so the warmth is spread more evenly across the room.

It is important to always place the radiator in the coldest spot, for instance underneath a window or against an outer wall. There should be a clearance of at least 10cm above and beneath the radiator. This ensures a better air flow along the radiator. When a heating pipe need to be installed through a wall, you need to make sure the hole is slightly larger than the size of the pipe. The prevents the pipe from ticking, which is caused by the pipe expanding and shrinking.
If you are using a thermostatically controlled tap, you should not place the tap too high. This has an adverse effect on temperature control.

Problems after installation
The radiator does not heat
The cause of this problem is almost never caused by the radiator. In most cases a small defect or insufficient water temperature is the cause of the problems. Possible causes are:

The installation is unstable;
The water head of the circulation pump is too low or the pump is not receiving sufficient power; because of this the rate of flow is too low in certain circuits;
The thermostat knob is covered by a piece of furniture or a curtain. Because of this the temperature near the thermostat knob is higher than in the room itself. The head will fully or partially close and the rate of flow will decrease;
The thermostat knob is not being operated the way it should
The main thermostat is being subjected to external heat sources, such as the sun; since the main thermostat has reached the desired heat, the radiators in other rooms will not be heated anymore;
The water temperature is too low;
Impurities in the body of the tap: when filling the installation floating particles can form a deposit near the tap and decrease the flow noticeably.
The radiator only partially heats: a phenomenon that sometimes can be explained very easily. When the desired room temperature has been reached the valve obviously closes, even when the radiator is not completely filled.
If the upper side of the radiator feels cold and the lower side warm, bleeding the radiator could be necessary. Because air rises, this problem occurs more often on higher floors.

Shortage of water
The heating system needs to be refilled if all radiators remain cold. If this needs to be done quite often, it might indicate that there is a leak in the system. Therefore you should keep a close eye on that.

Defective pump
When the radiators on the top floors do not warm up anymore and those on the ground floor stay lukewarm, there most probably is a problem with the circulation pump.

Noise in the radiator
Tubes expand and shrink because of the radiator warming up and cooling off. The material of the tube rubs against, for instance, a cupboard, a wall or the floor, creating the noise. Some noises and causes:

clac clac clac: indicates bad installation. Supply and return have been crossed.

tschschschsch: too high a flow at the level of the tap, caused by too much pressure. As a result of the installation, it is also possible that floating particles near the tap will descent and in this way decrease the flow considerably.

tic tic tic: there is tension in the installation. The cause of this can usually be found in places were pipes or consoles are in contact with floors, walls, and other materials. Consoles and other systems that do not feature acoustic protection hoods could also be the cause of this. These sounds can be heard throughout the entire installation.


Make sure the heating pipes in non-heated spaces are well isolated, so less energy is wasted.
Make sure the system is as small as possible. This way you will save on installation costs and reduce heat loss.
Turn the thermostat slightly lower. Barely noticeable in your home, but your electricity bill will be lower.
Lower the temperature half an hour to an hour before going to bed. By the time it will get noticeably colder, you will already be in bed. You can also do this when you leave the house for several hours.
If you have a slightly older boiler and set the standard temperature to 16°C during the night, less energy will be needed in the morning to completely warm your house again. If you have a new boiler you can easily set the system to a lower temperature during the night.
Warming a dry house is less energy-consuming. Therefore you should air your house for 15 minutes every day. In this way you can get rid of humidity without too much loss of heat.
Never cover radiators, for instance with a towel. Not only is it a waste of energy; it is also a fire hazard with convectors.
Fix reflective radiator foil behind the radiators, so heat will be reflected instead of disappearing into the wall.
Have your central heating system checked on a regular basis.
You loose a lot of heat through the windows, especially if you do not have double glazing. Closing curtains keeps the warmth inside.
Do not just close a radiator in the living room, corridor or hall. It is better to heat three radiator at a low temperature, than two radiator at a high temperature.
Place a letterbox with bristle, this keeps a lot of cold air outside.
Turn off the heating in rooms, you are not using that day.
Hang the drapes up to the windowsill and not below it. This way you prevent the warmth from disappearing behind the drapes.
If you have cold feet it is better to put on socks or slippers instead of turning the heat up.
