Hot Water Heat Pump Pros and Cons
Are you considering installing a heat pump water heater for your residence? If your water heater needs to be repaired or even replaced, then you may already consider a heat pump water heater as one of the many options for you and your home.
Heat pumps have been in use since they were invented in the 1940s. Although they became popular in the 1970s, many households still rely on traditional electric or gas heaters for hot water. That's why we put together a complete guide on heat pump water heaters and all the information you need to know when making this decision.
How does the heat pump water heater work?
Many homeowners may overlook the importance of a good water heater and the unexpectedly high price tag for hot water. The average family spends US$400 to US$600 each year for the luxury of hot showers and warm water. This price is partly due to the inefficiency of traditional water heaters. They can account for up to 20% of your entire utility bill. This is why many homeowners switch to heat pump water heaters and other energy-saving options.
Before deciding to use heat pump water heaters, you should understand how they work. Although most water heaters rely on gas or electricity to generate heat, heat pump water heaters are different-in fact, these pumps do not directly generate any heat. Instead, they absorb heat from the air and then transfer the heat to the storage tank of the device. This process is the working principle of the refrigerator, but the heat pump water heater is the opposite when the refrigerator discharges hot air. Because they breathe in hot air, this makes them ideal for warm climates!
7 advantages of heat pump water heaters
Heat pumps are a great choice for your home in many ways. Listed below are some of the advantages that can be gained by installing a heat pump.
1. Reduce operating costs
Compared with combustion-based systems, heat pumps have lower operating costs. The higher the energy efficiency of the system, the greater the long-term energy savings. Although the price of a ground source heat pump may even be as high as 45,000 pounds, this friendly environmental investment can help you save up to 1,400 pounds per year.
2. Less maintenance
Heat pumps require less maintenance than combustion heating systems. Periodically, once a year, certain details of the system must be checked, which can easily be done by yourself. On the other hand, professional installers must check every three to five years.
3. Better security
Heat pumps are safer than combustion-based heating systems. They operate safely, and because they rely on electricity and do not need to burn fuel to generate heat, they have fewer safety issues compared to similar products.
4. Reduce carbon emissions
The heat pump system can reduce your carbon emissions and has an efficient energy conversion rate. For example, the efficiency of water source heat pumps is quite high, close to 600%.
5. Provide cooling
During warm periods, the heat pump can reverse this process, so it acts like an air conditioning unit. In summer, the air-to-air heat pump can be easily switched to cooling mode.
6. Long life
The life span of heat pumps is relatively long, up to 50 years, but the average life span is between 14 and 15 years. Despite these numbers, they are very reliable and stable heat sources.
7. Eligibility for the RHI program
The government offers two different types of programs to assist in the installation of renewable heating systems. You may be eligible for payment under the domestic Renewable Thermal Incentive (RHI) program, which is open to homeowners, social and private landlords, and self-builders. On the other hand, non-domestic renewable thermal incentives are open to public sectors such as companies, organizations, and industries.
7 disadvantages of heat pump water heaters
Heat pumps are one of the most effective home heating solutions. However, the initial cash outlay may become a disadvantage because of this choice. Listed below are some disadvantages that need to be considered when choosing a heat pump.
1. High upfront costs
The upfront cost of heat pumps is high, but on the other hand, their operating costs translate into long-term savings in energy costs and lead to ways to reduce carbon emissions.
2. Difficult to install
Considering that research must be conducted to understand the movement of heat, local geology, especially ground source heat pumps, and the heating and cooling requirements of your home, heat pumps are quite difficult to install.
3. Problematic sustainability
Some fluids used for heat transfer have problems with the sustainability and therefore cause environmental problems. Therefore, it is recommended to use biodegradable fluids.
4. Need a lot of work
The heat pump installation process requires a lot of work and damages your house and garden. A related example is the need to penetrate through building cladding.
5. Cold weather problems
Few heat pumps encounter problems in cold regions, which will eventually damage the system, so full heat pump efficiency cannot be achieved in cold weather. Nevertheless, the upgraded heat pump system may overcome this problem. Always check the seasonal coefficient of performance (SPF) of the heat pump.
6. Not completely carbon neutral
Heat pumps rely on electricity to run, which means that they are difficult to fully achieve carbon neutrality. However, heat pumps generally have a higher coefficient of performance (COP), which means that as the outside air cools, they are more efficient.
7. Need planning permission
Some places require special planning permission, some don’t, depending on the location and size of your property.
