Help with choosing a drainage tray

Both the NEO and ECO models have thermostatically controlled heating pads. NEO has a thermostat that starts the heating process with the same power from +2° degrees. The ECO trays have a smart energy saving function with two thermostats. The primary thermostat starts heating the mat at half power from +2° degrees and the secondary one turns on full power at -8° degrees when it’s really needed.

Our drainage trays collect the condensed water, making sure it does not freeze, even during the really cold months. For a more in-depth understanding of how our trays work click here!

Our drainage trays are manufactured from a special type of plastic that is UV and heat resistant. They have heating mats with long heating cables inside them.

Different drainage trays use different amounts of power. This also depends on where they are installed. In northern Sweden where there is colder weather for a longer period than in southern Sweden, the trays need to operate for a longer period than those installed in, for example, Scania in the far south of the country.

The product pages show a comparison between the NEO and the ECO versions of the heat trays. The comparisons are for the six-month period when the weather in Sweden is cold, i.e. from 1 October to 31 March.

You already require additional heat from 20cm from the tray. It is also important that you choose a heating cable that has the right power and is thermostatically controlled so that it does not provide heat when it is not needed.

Villas built over the past 25 years often have downpipes connected to the storm drains and there will be some heat emanating from those. If the rainwater is drained to a French drain then you might need to use additional heating. Generally we recommend that a 30cm heating cable be plugged into the downpipe in southern Sweden, in the middle of Sweden a 60cm cable and in the northern parts a 100cm cable.

You can install the drainage tray yourself with a plug into a grounded electrical outlet. But an electrician or a cooling technician with an electrical certification can also install it.

Yes, you can! All installation instructions can be found under each product's document tab, or here.

Different drainage trays use different amounts of power. It also depends on the region where they are installed. In northern Sweden where there is colder weather for a longer period than in southern Sweden, the trays need to run for a longer period than those installed in, for example, Scania in the far south of the country. There is a table of comparison of all Pancake trays and Pro 791.

Are the house's drainpipes connected to the storm-water drains or to a French drain? – If yes, measure the distance from the middle of your outdoor unit to the nearest downpipe. Install 30cm of heating cable inserted into the downpipe in Götaland, in Svealand 60cm of cable and in Norrland 100cm.

Do you have a basement with a floor drain or other drain? – If yes, measure the distance from the middle of your outdoor unit to a suitable entry point to the basement. Perhaps there are existing entry points, e.g. for ventilation, a wooden window frame, otherwise you might need to drill through the outside wall. You only need to measure to the inside of the basement wall for the heating cable. In the basement you would usually use fixed pipes, without heating cable.

The last option is to dig a French drain. Google "digging a French drain".

A cable-wire or draw spring is a tool used by electricians to easily pull installation cables through conduits. Available in building supply stores, such as Biltema, Jula, Hornbach, Clas Ohlson. Prices from around SEK 50.

You can use a stiffer cable, thicker steel wire or a wire rope; if the ends are too sharp, they can be taped so that they do not get stuck. Remember that it must be longer than the insulated hose. Then attach the end of the heating cable using good tape – and draw through carefully.

It is possible to use our trays abroad. Just remember that the voltage should be 220-240v / 50hz. You must, of course, comply with each country’s electrical safety laws.
