Why Heat Pumps
The demand for hot water contributes around 40%- 60% of the energy bills in a typical Kenyan household. Therefore, it is important to understand which technology can produce hot water in the most energy efficient manner.
The most traditional hot water systems used in Kenya are electric boilers and solar water heaters. Heat pumps are a renewable heat technology which has been used widely in Western countries since the last 8-10 years and was introduced most recently in the Kenyan market. This technology provides for a far greater energy efficient solution to your hot water needs than a traditional hot water system.
How a heat pump works
Heat pumps are very cost effective solutions since they transfer heat from the air instead of producing heat like boilers do, this is referred to as renewable heat.
01
A fan draws in air containing heat energy, across the evaporator
02
The evaporator turns the liquid refrigerant into gas
03
04
05
The refrigerant reverts back to a liquid after expansion & continues back to the evaporator for the proceed

Daisy Heat Pumps vs Solar Water Heaters
Heat pumps and solar water heaters are BOTH considered under the category of renewable heat.
Complete control over the weather isn’t possible, however complete control over your hot water is with Daisy Heat Pumps.
Day or night, rain, hail or shine; our hot water heat pump technology will deliver your hot water at your desired temperature with greater efficiency than conventional solar water heaters – without the need for sunlight!
Common misconceptions about solar water heaters
Solar water heaters rely mainly on the sun to heat the water and therefore solar resource is free and one only needs to purchase the components. This statement is wrong because Solar water heaters have a tank storing the hot water which has an electric element as back-up. This element consumes on average 2,000-3,000 watts. Over a 24 hours cycle and over a period of 12 months, the electric element will be working to compensate for the lack of solar radIation and the demand of hot water. Daisy heat pumps are more efficient than a solar water heater and consume 30-50% less electricity. A solar water heater can be integrated into a heat pump to pre-heat the water during the day when there is good solar radiation. The electric element in the tank of the solar water heater must be turned OFF as the heat pump will substitute its functionality at a fraction of its electricity consumption.

Installing a heat pump is easy
Heat pumps up to 120L can be wall-hanged and can replace an equivalent electric boiler. Heat pumps of 150 liters and above are self standing on the floor. Connection of the heat pump is identical to the boiler with a cold water inlet and hot water outlet.
Can heat pumps work with a Solar PV system ?
A solar PV system can be used to operate a heat pump. Typically the AC current is converted into DC current with an inverter which then supplies DC current to the heat pump. During the day, the solar PV system will supply power to operate the heat pump; at night, a battery system can be used to store the energy and operate the heat pump when there is no solar radiation. Since the energy needs of a heat pump are limited to about 400-500watts,
