Air to Water Heat Pump Price

Information About Air to Water Heat Pump Prices

Air to water heat pumps are affordable air source heat pumps, which allows you to cut down your heating costs by up to thirty percent when compared to conventional heating systems which rely very much on gas, oil and electricity as their main heating source.

An air to water heat pump is an initial investment into making your house energy consumption rate more cost efficient over the long term. The extent to which the benefits will outweigh the costs, in terms of heating efficiency, will depend on the price you are paying for electricity at the moment, local climate, the type of fuel used for heat conversion purposes on your previous heating system, and the HSPF (Heating Season Performance Factor) value assigned to the heat pump you're installing.

If you wish to get customised quotes on air to water heat pumps, you can fill in the contact form on the right and wait to be contacted by our team. We will connect you with our qualified suppliers - this is totally free of charge and with no obligation. If you want to get a general idea about the air to water heat pump price, you can read the lines below.

Given the somewhat high initial air to water heat pump price, you might expect the return on your investment to be achieved in three to seven years, depending on how efficient the installed air to water heat pump will prove to be, how often and at what rate will you be using the heat pump, and whether you have applied for Renewable Heat Incentive (RHI) scheme, which in essence is a yearly payment provision by the UK government, among other heat pump grants, offered to those who have chosen to heat their homes with the help of renewable energy sources.

How Does an Air to Water Heat Pump Work?

The air to water heat pump captures the heat from the air that in the meantime is being warmed by the sun, which later is used for steam generation and consequently heat emission. Read more about the air to water heat pump system to get an understanding of how it works.

1 1: An outdoor unit takes in heat from the ambient air and transfers it to a coolant. 2 2: A compressor increases the temperature of the coolant further. 3 3: The coolant transfers the heat to a hot water reserve tank via a heat exchanger. 4 4: Hot water from the tank is circulated to radiators and faucets in the house. 5 5: Cold water is transported back to the water reserve tank. 6 6: The coolant is cooled by the water and transferred back to the outdoor unit to be heated again.

Air to Water Heat Pump—Related Costs

The costs associated with the procurement and subsequent utilisation of an air to water heat pump can be divided in two:

  • The installation costs (which are concerned primarily with the air water heat pump price coupled with the costs incurred when installing the pump).
  • The exploitation expenses, which will be directly affected by how you use the pump.

Installation Costs

Given the estimations put forward by The Energy Saving Trust (EST), it is assumed that the installation costs of an air to water heat pump, would vary in the range of £8,000 and £18,000.

However, the installation of a heat pipe system is not a complex process, since it typically lasts a few hours only, it is recommended to avoid installing the pipe on your own. Instead, the help of a professional installer, since the heating efficiency will very much depend on the heating system output which might be negatively impacted if the system was not properly installed.

Running Costs

If the costs of installing an air heat pump are more or less rigid, the difference in price is limited to the type of air pump, and therefore cannot be influenced one way or the other, then the costs of running an air to water heat pump, for the most part, can be leveraged in the way that would comply with your efficiency targets.

The costs experienced while operating an air heat pump are directly linked to factors like household insulation, the square footage that requires heating, the amount of produced heat for a certain quantity of electricity that is being consumed, and the heat source (outside air) temperature variations.

In addition to the basic function of heat generation, the latest versions of air to water heat pumps, which are known as ‘integrated heating systems’, are capable of providing domestic water heating as well, without compromising the overall performance of the heat pump with respect to heating efficiency. Such a system, whilst more expensive than the ordinary air source heat pumps, can reduce your water bills by up to thirty percent, which proves to be a significant gain when saving on housing utility payment.

How to Assess the Energy Efficiency Costs

In order to estimate the extent to which you will be able to benefit in terms of price efficiency ratio, two coefficients need to be considered:

  • The Coefficient of Performance (COP), which very much depends on the technical characteristics specified by the pump manufacturer. Typically, the COP for an air to water heat pump is around 3.3, what means that for every kWh of supplied electricity the pump generates up to 3.3 kWh of heat. The COP value is directly proportional to the conditions of the outside environment, which entails that a decrease in temperatures outside, will pose a downward pressure on the COP levels.
  • The Heating Season Performance Factor (HSPF), which is the total space required to be heated, expressed in Btu (British Thermal Unit - a unit of energy being equal to about 1055 joules), divided by the total electric energy that is consumed by the heat pump expressed in Wh (watt-hours). According to the HSPF indicator, the most efficient heat pumps would range between 8 and 9 on the HSPF scale. Hence, if you are very much concerned about taking the most out of your pump during the cold season, it is recommended to consider the heat pump which comes with the highest HSPF.

The drawback to be aware of when discussing the heating cost efficiency rate of an air to water heat pump is the pump’s heating performance is contingent on the outside temperature variations. In other words, the closer the outside and inside temperatures are to each other, the more cost-efficient your pump will be, whereas it won’t require considerable heating energy to warm the indoor space. Thereby, the efficiency rate of an air heat pump might fall if a high-temperature output is demanded, consequently raising the pump’s running costs.

There are no current solutions designed to counter this limitation since it is embedded in the functioning principles of a heat pump. Therefore, if you look to keep your costs down for an extended period of time, it is desirable that you do not set maximum temperature requirements unless there is no way to avoid it.
