Did you know?
- Each of us uses between 14500 to 22000 litres of hot water every year to wash ourselves, our kitchen wares, our clothes and the list goes on and on. (That is 58 billion litres of hot water each year for New Zealand)
- This equates 40% to 50% of the electricity bill for domestic hot water usage.
"Performance Plus" Domestic Hot Water Heat Pumps
Hot Water Heat Pump Ltd Water Heaters are designed on the same principal as our Swimming Pool Heat Pumps. They are made to heat domestic hot water more efficiently than electric resistance or gas/oil water heaters. They can provide the same amount of hot water at 1/2 to 1/3 of the cost of other heaters. With increasing energy problems, more people are getting interested in this idea and the number of residential users is increasing daily.
"Performance Plus" Domestic Hot Water Heat Pumps are the most cost-effective in buildings where hot-water consumption is relatively high. The higher the consumption the more savings in hot-water energy costs. The higher the consumption the less time it takes to offset the higher initial investment cost of the "Performance Plus" Domestic Hot Water Heat Pump over other available water heating technologies.
"Performance Plus" Domestic Hot Water Heat Pumps are designed to operate with existing electric hot-water tanks, they are also designed to operate with a specifically made Combo Hot Water Pressure Cylinder.
How Heat Pumps Save Money
Common Electric resistance hot water cylinders normally consume around 2.5 times more electricity compared to the Domestic Hot Water Heat Pumps , or in dollar value, for every $1000 you currently spend on your domestic hot water heating, the "Performance Plus" Domestic Hot Water Heat Pumps could reduce expenditure to around $300. This means an average cost savings of around 60 percent.
"Performance Plus" Domestic Hot Water Heat Pumps extract the free and widely available heat from the ambient air and direct this heat to the Hot Water Cylinder for the residence hot-water demand. Generally talking, Heat Pumps are like home refrigerators in reverse. They mainly consist of a compressor, fan, evaporator and the heat exchanger. The compressor requires electricity to compress the refrigerant and vaporize it, and the fan requires a small amount of electricity to continually blow air across the evaporator coils when the unit is operating. The only electricity cost is the operation of the compressor and the fan in order to collect the free heat and pump it to the hot-water cylinder. During rare periods of excessive sub zero ambient conditions, the use electrical element is available for a back up and boosting system.
Consider the following conditions when choosing a Domestic Hot Water unit:
- Electric resistance hot-water cylinder are used
- Electricity shortages are high due to high consumption or other problems
- Four or more people are living in a residence
- High consumption of hot water from 7a.m. to 7 p.m.
- A new building is being built
- Energy conscious or an environmentalist

"Performance Plus" Domestic Hot Water Heat Pumps are designed to maintain water temperatures up to 60C or act as a energy saver up to 50-55C with an electric booster to bring the water temperature up to the desired temperature. The method used depends on the home owner and various factors in regards to the installation.
"Performance Plus" DHW heat pumps are made in New Zealand for New Zealand conditions. They are made to operate in conditions found about anywhere in the country and can function in air conditions below 0C. This makes "Performance Plus" DHW units the only commercially manufactured heat pumps made to operate in winter conditions found in the lower south island of New Zealand.
DHW150 > Avg. kW out: 4
kw ratings are nominal. Varying water temperature and air temperature can effect kW's.
How the system works:
The Heat Pump is normally installed outdoors with the water circulating pump installed inside the hot water cupboard. The water circulating pump only runs when the heat pump is heating. The temperature sensor is attached to the water tank and insulated if there is no pocked built into the tank.
