Husky heat pumps can achieve hot water up to 60˚C and heat 150 litres in only 20 minutes. This is when our pumps are combined with our unique heat transfer hot water cylinder. Is a buffer tank needed?
Will I need to install larger radiators in my home? Possibly. If your current heating system is a condensing boiler, if installed correctly, they only condense when producing hot water below 60˚C. A heat pump will provide virtually the same heat as this. However it is important to note that the lower temperatures the heat pump produces, the more efficient the system. Therefore having oversized radiators is of benefit. Our engineers will

actually takes heat from the home to perform a reverse cycle defrost. If there is no buffer, the house will begin to get colder and colder during this period. If however a buffer tank is installed, this will continue to feed the home with heat during the defrost cycle. It is simple logic. Some installers insist it isn’t a problem without a buffer tank. We do not agree. If a heat pump is oversized, is it less efficient? No! It is a common misconception that air to water heat
