Use ambient air to heat your pool 2 | Electroheat MKV pool heat pumps www.waterco.com
Energy efficient heating A swimming pool is a major financial investment. Getting the most out of your pool, means keeping the pool at a swimmable temperature for the maximum number of hours in each day and the maximum number of days in each year. A pool heat pump will economically keep your pool warm 24 hours a day. Compared to gas and electric heaters, the Electroheat MKV pool heat pump range use just a fraction of the energy to generate the same amount of heat and unlike solar heating; there is no reliance on the sun as the latent heat in the air is used. For every 1kW of electricity consumed, Electroheat can produce up to 6kW of heat. Electroheat MKV pool heat pumps | 3

WHAT IS THE ELECTROHEAT’S HEATER RUNNING TIME? Most units should be sized to operate during the pool filtering cycle time of 8 - 12 hours daily, providing a steady flow of heated water. On warmer days the heater will run less because the heat loss will be less. Electroheat heat pumps have a lower heating capacity on a BTU/hr basis compared to fossil fuel based pool heaters such as gas heaters. Therefore, Electroheat heat pumps require longer operation to accomplish the desired temperature. Between 10°C to 18°C, it will increase your water temperature by 3°C to 5.5°C a day. Over 21°C you should obtain an increase up to 0.8°C a hour and over 26°C up to 1.1°C an hour depending on the size of the pool, the size of the heat pump, the water temperature, and the ambient air temperature at the moment of operation. Even though the Electroheat may require longer operation, it will still heat the pool far more economically. HOW DOES ELECTROHEAT COMPARE WITH SOLAR HEATING AND GAS HEATING? Solar • Fuelled by the power of the sun, solar heating systems are a low-cost method of heating up your pool water. • As solar heating is reliant on the sun, they are best used to extend the swimming season. • Virtually no operating costs, just the cost of electricity to pump the pool water through the solar absorber on the roof. Gas heaters • Gas heaters are the fastest method for heating your pool, providing a comfortable temperature for swimming on demand. Gas is best for heating pools or spas for short periods of time. • Gas heaters can easily maintain any desired temperature regardless of the weather. • Gas heaters are effective, but expensive to operate. Heat pumps • Heat pumps may not heat up the swimming pool as fast as gas heaters, but are more energy efficient. • Heat pumps require a small amount of electricity; its heat energy source is extracted from the ambient air. SHOULD I USE A POOL COVER? The most effective way to prevent heat loss is to install a pool cover. An un-blanketed pool loses 2-3 times more heat than a blanketed pool. Pool covers virtually eliminate evaporation and reduce heat loss by insulating the surface of the pool, greatly reducing pool heating costs. As with all pool heaters, it would be advisable to use a pool cover at night, and when the pool is not in use. WHAT IS THE MINIMUM AMBIENT OPERATING TEMPERATURE? The heat pump will actually operate down to an ambient air temperature of 10°C, but with minimal heat output. Therefore we recommend that the minimum operating temperature should be 10°C. WHAT IS THE BEST LOCATION FOR THE ELECTROHEAT? The location of the Electroheat is very important in keeping installation costs to a minimum, while providing for maximum efficiency of operation as well as allowing adequate service and maintenance access. The unit should be located as close as practically possible to the existing pool pump and filter to minimise water piping. The use of 90 degree bends and short radius elbows in the water piping should be kept to a minimum. The longer the distance from the pool, the higher the heat loss from the piping. CAN THE ELECTROHEAT BE ENCLOSED? The Electroheat is designed for outdoor installation and should not be installed in totally enclosed areas such as a shed, garage, etc., unless mechanical ventilation is provided to ensure adequate air exchange for proper operation. Re-circulation of cold discharged air back into the evaporator coil will greatly reduce unit’s heating capacity and efficiency. WHAT IS THE ELECTROHEAT’S PERFORMANCE DEPENDENT ON? Performance will fluctuate depending on water and weather temperatures. 5 important factors determine the performance of Electroheat: 1. Size of the pool 2. The desired temperature of the pool 3. Ambient air temperature - the warmer the air, the better the performance 4. The presence of a pool cover 5. The size of the heater Frequently asked questions Electroheat MKV pool heat pumps | 9

Compared to gas and electric heaters, Waterco Heat Pumps use a fraction of the energy to generate the same amount of heat and unlike solar heating; there is no reliance on the sun as the latent heat in the air is used. Waterco Heat Pumps are an ideal solution for heating: • Swimming pools to extend the season • Swimming pools for year round enjoyment • Plunge pools • Swim spas and spas 50 $ 40 $ 30 $ 20 $ 10 $ 0 $ Heat Pump Natural Gas Propane Electric
4 | Waterco Heat Pumps www.waterco.com HEAT EXTRACTION The fan circulates air through the evaporator air coil that acts as a heat collector. The liquid refrigerant in the evaporator air coil absorbs the available heat from the ambient air. HEAT TRANSFER The heat from the hot refrigerant flowing inside the heat exchanger is then transferred to the pool water. HEAT INTENSIFICATION The compressor then receives the warmed refrigerant and intensifies the heat. The intensely hot refrigerant is then pumped into the heat exchanger. RECYCLE The refrigerant restarts the process and flows through the evaporator air coil to collect heat once again. HOW WATERCO HEAT PUMPS WORK Waterco Heat Pumps use refrigeration technology to extract heat from the surrounding air and transfers it to the swimming pool. 1 2 3 4 5 6 7 8 9 10 Heat Extraction Heat intensification Heat Transfer Recycle 1.

Waterco Heat Pumps | 9 WHAT IS THE ELECTROHEAT’S HEATER RUNNING TIME? Most units should be sized to operate during the pool filtering cycle time of 8 - 12 hours daily, providing a steady flow of heated water. On warmer days the heater will run less because the heat loss will be less. Electroheat heat pumps have a lower heating capacity on a BTU/hr basis compared to fossil fuel based pool heaters such as gas heaters. Therefore, Electroheat heat pumps require longer operation to accomplish the desired temperature. Between 10°C to 18°C, it will increase your water temperature by 3°C to 5.5°C a day. Over 21°C you should obtain an increase up to 0.8°C a hour and over 26°C up to 1.1°C an hour depending on the size of the pool, the size of the heat pump, the water temperature, and the ambient air temperature at the moment of operation. Even though the Electroheat may require longer operation, it will still heat the pool far more economically. HOW DOES ELECTROHEAT COMPARE WITH SOLAR HEATING AND GAS HEATING? Solar • Fuelled by the power of the sun, solar heating systems are a low-cost method of heating up your pool water. • As solar heating is reliant on the sun, they are best used to extend the swimming season. • Virtually no operating costs, just the cost of electricity to pump pool water through the solar absorber on the roof. Gas heaters • Gas heaters are the fastest method for heating your pool, providing a comfortable temperature for swimming on demand. Gas is best for heating pools or spas for short periods of time. • Gas heaters can easily maintain any desired temperature regardless of the weather. • Gas heaters are effective, but expensive to operate. Heat pumps • Heat pumps may not heat up the swimming pool as fast as gas heaters, but are more energy efficient. • Heat pumps require a small amount of electricity; its heat energy source is extracted from the ambient air. SHOULD I USE A POOL COVER? The most effective way to prevent heat loss is to install a pool cover. An un-blanketed pool loses 2-3 times more heat than a blanketed pool. Pool covers virtually eliminate evaporation and reduce heat loss by insulating the surface of the pool, greatly reducing pool heating costs. As with all pool heaters, it would be advisable to use a pool cover at night, and when the pool is not in use. WHAT IS THE MINIMUM AMBIENT OPERATING TEMPERATURE? The heat pump will actually operate down to an ambient air temperature of 10°C, or 1° if fitted with hot gas deicing but with minimal heat output. Therefore, we recommend heat pumps be operated in the warmest part of a 24 hour period to increase operating efficiency. WHAT IS THE BEST LOCATION FOR THE ELECTROHEAT? The location of the Electroheat is very important in keeping installation costs to a minimum, while providing for maximum efficiency of operation allowing adequate service and maintenance access. The unit should be located as close as practically possible to the existing pool pump and filter to minimise water piping. The use of 90 degree bends and short radius elbows in the water piping should be kept to a minimum. Longer distances from the pool increase piping heat loss. CAN THE ELECTROHEAT BE ENCLOSED? The Electroheat is designed for outdoor installation and should not be installed in totally enclosed areas such as a shed, garage, etc., unless mechanical ventilation is provided to ensure adequate air exchange for proper operation. Re-circulation of cold discharged air back into the evaporator coil will greatly reduce unit’s heating capacity and efficiency. WHAT IS THE ELECTROHEAT’S PERFORMANCE DEPENDENT ON? Performance will fluctuate depending on water and weather temperatures. 5 important factors determine the performance of Electroheat: 1. Size of the pool 2. The desired temperature of the pool 3. Ambient air temperature - the warmer the air, the better the performance 4. The presence of a pool cover 5. The size of the heater Frequently asked questions

Note: Heat Pump Size and performance are influenced by ambient temperature, humidity, use of a pool cover, night time temperature, pool location, wind factor, water features and if the unit is switched off over night. The recommended sizing in the table above is based on operating the unit up to 10 daytime hours with the pool subjected to normal suburban wind. No allowance has been made for the cooling effects of water features, negative edges or high wind areas. Therefore, any under sizing of the heater for your pool heating requirements is not the responsibility of Waterco.
