Tennis Court Heating and Winterising – Economical Tennis Dome Heating

A tennis court can be used in winter on two conditions: it has to be protected from precipitation and wind – with a dome, hall or cover – and the playing area has to be warmed enough that the surface does not freeze and the players do not get cold. In a tennis dome, heating is most economical if we do not heat the whole air space of the dome, but use radiant heating to warm the court and the players directly. Infrared heating laid under the court, controlled by zone, suits this.

Winterising: how can the court be protected?

The aim of winterising is that snow, rain and ice do not make the court unusable. The options range from full covering to simple maintenance:

• Dome or court cover. The simplest solution: it gives protection against snow, rain and cold, so you can play in bad weather too. A dome is easy to assemble and dismantle, so it is flexible.
• Winterising cover. Some courts get a special cover that resists cold and moisture and is easy to put on.
• Snow removal. Where there is no covering or heating, snow has to be cleared regularly with a snow shovel or snow blower. A cleared surface warms up faster in the sun.
• De-icing with salt. Below freezing it helps prevent ice formation, but it has to be handled carefully: salt can damage the surface of the court, and it also burdens the environment.

These steps protect the court, but in themselves they do not make playing pleasant. If the aim is regular winter training or renting out the court, the covered space also has to be heated.

What heating methods can be considered?

Under-court heating

One of the most efficient and most commonly used solutions. Electric heating cable, heating film or a water-based pipe network installed under the court warms the ground and the surface, so the heat arises where the players move. With a thermostat, the temperature of the court can be set precisely.

Infrared (radiant) heating

Infrared radiation warms not the air but the surfaces and people. With heating film under the court or radiant panels, the surface warms quickly and soon becomes playable, and the system is easy to control.

Warm-air heating

An electric or gas-fired appliance blows warm air over the court. It protects effectively against the cold, but it has to warm the whole air space, and when a door is opened or the space is ventilated, part of the warm air escapes.

Geothermal heating and solar collectors

A system using ground heat and a solar collector use renewable energy, so they are environmentally friendly and can bring savings in the long term; the initial cost of both is higher. A solar collector, moreover, receives the least solar energy in winter, when the court's heat demand is greatest, so for winter court heating it plays more of a supplementary role.

How does tennis dome heating become economical?

The cost of heating is determined not only by the equipment but also by the design and the way it is used. It is worth paying attention to these:

• Thermal insulation. Proper insulation retains the warmth and reduces energy loss – every economical system starts with this.
• Timing and remote control. Heating fitted with a timer heats only when really needed: before the players arrive and during booked hours. Controlled remotely, it can be started even if an unexpected booking comes in.
• Sizing. In designing the system, the size of the court, the local weather, the times of use and the available energy source decide together. An oversized system is needlessly expensive, an undersized one does not hold the temperature.
• Regular checks. The efficiency of heating left without maintenance falls, and hidden faults can cause significant extra consumption. Checking helps to spot these early.

When comparing systems, do not look only at the investment cost: energy efficiency, maintenance needs, service and maintenance costs and environmental impact together give the full picture.

Why is infrared heating advantageous in a tennis dome?

Heating the large air space of a dome is expensive, and the warm air leaves at every opening. Radiant heating gets around this problem:

• It does not heat the air. The radiation reaches the court directly, so there is no need to warm the whole air space first, and no need for long, energy-hungry pre-heating.
• Controllable by zone. Heating film under the court or radiant panels can be aimed precisely, so only the area where heat is really needed gets it – for example the playing area or where the players stay.
• Smaller ventilation loss. Because there is no large volume of air to keep warm, less energy is lost when a door is opened or the space ventilated.
• Simpler maintenance. There is no combustion and no moving part, so there is less wear, and maintenance is generally simpler and cheaper than with conventional heating systems.

In open, uncovered areas – a terrace, spectator stand, rest area – the dome does not retain the warmth. There a targeted outdoor dark radiant heater is the more practical solution.

Before you decide

Every court is different: the material of the dome, the ground, the pattern of use and the available electrical capacity all matter.
