High Temperature Air Source Heat Pump

High Temperature Air Source Heat Pump

High temperature air source heat pump are an efficient alternative to a traditional boiler based heating system. They also provide cooling during the summer.

They have been compared to the oil boiler case by calculating primary energy consumption, simple payback periods and life cycle costs and by evaluating net present savings and CO2 emissions avoidance.

Energy Efficiency

Unlike furnaces and electric resistance heating systems, which require fossil fuels to be delivered to your home and burned for heat, air source heat pumps convert electricity into thermal energy that is transferred directly to the home. This results in primary energy consumption, cost and carbon dioxide emissions savings. This is especially true when paired with renewable electricity generated from wind turbines and hydroelectric sources.

However, because a standard air source heat pump takes longer than a boiler to heat a home’s spaces, the installation requires larger radiators and good insulation to prevent heat from escaping during this process. High temperature air source heat pumps, on the other hand, operate at a similar level to conventional gas boilers and will not require expensive new radiators or insulation when replaced with an existing boiler system.

HSHPs can be combined with thermal storage systems that use resistance heating to increase energy efficiency even further, particularly when operated under time of use electricity rates. The use of storage increases efficiency during the day, when solar heat is available, and lowers energy costs at night when the demand for electricity is greatest.

Purchasing a high-efficiency ASHP is a smart investment that will save you money and reduce your greenhouse gas footprint. Whether high temperature air source heat pump you choose a gas-powered or a renewable electricity model, look for a unit with a heating seasonal performance factor (HSPF) of at least 7.5. To be sure you’re getting the best value, ask for referrals from family, friends or green-energy resource groups to find a contractor who is familiar with this technology and knows how to install it properly.


With only a few brands available in the UK, it’s worth checking out the reputation of each before making a purchase. Daikin is one of the leading brands, and offers both wall-mounted units and floor-standing models with a hot water cylinder built into them. However, the latter are slightly heavier than a regular heat pump – by around 10 kg – so you will have to factor this extra weight into your decision making process.

The main reason for choosing a high temperature air source heat pump is that it should be able to provide your home with the same heating levels as a standard gas boiler. A standard heat pump takes much longer than a boiler to heat a property, so requires larger radiators and good insulation to stop heat from escaping the building. Installing such measures can be expensive and disruptive, especially for homeowners with listed houses.

All heat pumps start to struggle as outdoor temperatures drop; the heat they can extract drops, and performance deteriorates. However, there are special heat pumps that can operate at very low temperatures.

The best way to find a supplier who specialises in these is to ask for recommendations from friends, family members or business associates. Alternatively, you could contact your local green-energy resource group and see if they can help. When you have chosen a contractor, get several price quotes and make sure the installer has experience with installing heat pumps.


Having to deal with noise pollution can be very difficult and disruptive. It affects our ability to communicate, work and sleep. high temperature air source heat pump Therefore, it’s vital that the technology we rely on in our homes doesn’t produce excessive levels of noise, especially when it is running.

The good news is that heat pumps are quieter than most other types of heating. They typically generate 40-60 dB at a distance of 1 metre and noise levels will drop the further you are away from them. However, there is a common misconception that a heat pump sounds like a log burner when it’s in operation and many customers worry about this.

Heat pumps actually produce far less noise than a log burner because they have an internal acoustic insulation system that effectively absorbs the sound waves generated. However, the sound from a log burner is much more persistent and can be heard throughout your home which is why it’s important to consider the space available in your property when considering a new heating solution.

The optimum size of a heat pump for your property will depend on the number of rooms and their layout, insulation levels, room sizes and whether they are heated with radiators or underfloor heating. Your local heating engineer can advise you on what size heat pump is right for your property. They can also help with the sizing of an outdoor unit to ensure that it’s not too noisy and is located in the best position.


If you want your air source heat pump to provide maximum efficiency during the cooler months it is important to carry out preventative maintenance. This includes cleaning coils, filters and fans. Dirty filters starve the system of air and can cause it to operate at reduced performance for extended periods of time. This leads to premature system wear and tear.

Air to air heat pumps absorb the heat in the air and transfer it to your central heating system or radiators. This will provide heat in your home and hot water. Air to water heat pumps will absorb the heat in your water supply and provide hot water or underfloor heating in a room.

Both systems can benefit from a yearly inspection by a professional heating engineer. This will ensure that the heat pumps are working to their full potential and identify any potential issues before they develop into more severe problems.

As with all energy efficient heating systems the cost of running a high temperature air source heat pump will depend on how well your home is insulated and what heating you require. However, for many homes that already have loft insulation and double glazing it is likely that a low temperature air source heat pump would provide the most cost-effective heating solution. This is because a low temperature system will only provide your radiators with hot water at temperatures of around 45degC. This is sufficient to keep most households comfortable but is unlikely to be enough for properties that are badly insulated and suffer from substantial heat loss through single glazed windows or poor quality flooring.
