Key Features Stops water surface from freezing, allowing your pond to breathe. Easy to use, no fuss installation. Suitable for patio and garden ponds up to 5000L. Power saving convection design, 66% less energy used. 2 year manufacturers guarantee. The Blagdon Affinity Ice Vent Pond Heater allows you to maintain the perfect environment for your pond throughout the winter months. While it may not be essential to heat your pond over the winter, when the water surface freezes an ice layer develops which can starve your pond of oxygen and trap toxic gases within. So it is important to ensure an ice free area to allow poisonous gasses to leave the water whilst simultaneously helping to aerate the water. The Blagdon Affinity Ice Vent creates an ice free area on the surface of your pond, enabling your pond to breathe, with vital oxygen entering the water and poisonous gasses from dead plants or fish waste escaping safely. Its unique convection design allows it to run at only 50 watts saving
