Hot Water Heat Pump VS Solar Water Heater

What is a Solar Water Heater?

A solar water heater works by absorbing heat directly from the sun rays and then heating a fluid, like water. It can also generate electricity when it has collected more than the maximum temperature setting. Solar water heaters are one of the most significant options for obtaining renewable energy and reducing greenhouse emissions. The major components of a solar water heater are a collector, a storage tank, and an insulation layer.

During the day, the solar water heater system can provide water at a 65%-80% energy efficiency rate. However, The system will need to heat the storage tank via either a gas booster or an electric element booster to work at night or on cloudy days.

What is a Hot Water Heat Pump?

The hot water heat pump takes heat energy from the air and delivers it to the water. As a result, it is also known as an air source heat pump. Every 1kW electrical energy it consumes will drive the unit to generate 3-5kW heat energy. When utilized properly, they can reduce 50-60% of your electricity bills, save energy and minimize greenhouse gas emissions.

Solar Water Heater vs. Hot Water Heat Pump

For homeowners who want to lower their carbon footprint, solar hot water and heat pumps offer a good option. But for those seeking a more convenient and low maintenance deal, heat pumps usually provide a better solution:

Solar Water Heater

  • Only heat water in the daytime with direct sunlight. The solar water heater is weather-dependent. Since there is no sunlight at night, on a cloudy day or rainy day, the radiation can be very weak, making the collector cannot absorb much heat. If you plan to use it at night, the solar water heater may not function.
  • Need accessories. Almost all solar water heaters require a gas or electric booster switch to ensure that you have hot water even in the colder months and cloudy, rainy days.
  • Higher upfront cost. A solar water heater usually requires more piping systems, meaning that a solar water heater will need extra piping costs.
  • High installation requirements. A solar water heater occupies a large roof area and requires higher installation requirements than a hot water heat pump. The roof of the house should be tall enough to avoid being obstructed by sunlight. Panels and tanks must be assembled, and installation time is expected to be about 6 hours.
  • High maintenance cost. Since a solar water heater is installed on the roof, it is easily affected by natural weather such as lightning strikes, strong wind, and hail, requiring higher maintenance costs.

Hot Water Heat Pump

  • Can work in any season. A hot water heat pump has no limit in the usage time. For example, you can use the hot water heat pump to heat water in any season or any time of day, taking advantage of off-peak tariffs. As long as the air exists, heat pump can work for 365 days.
  • No accessories are needed. Hot water heat pumps do not need a booster and reduce your electricity bills.
  • Lower upfront cost. Compared with the solar water heater, the upfront cost of the hot water heat pump can be up to 50% lower with fewer piping costs required.
  • No installation requirements. A hot water heat pump does not need roof space and can be placed in an inconspicuous place.
  • Low maintenance. A hot water heat pump is easily sheltered from harmful weather. Generally, a water heat pump requires less maintenance than a solar water heater.

Should You Choose Solar Power or a Heat Pump?
