High Temperature Heat Pump, Cost, Benefits, Guide 2025

High temperature heat pumps always provide heat with efficient delivery with good water temperature. And these systems easily provide 60 to 75 °C heat, which is the most ideal for the home. And it also relies on radiators, which are attached to these pumps.

High-temperature heat pumps absorb heat from various sources, such as the ground and water, and also convert it into usable heat. Homeowners can rely on this heating system without upgrading.

These systems can be used as a central heating system as well. These systems are also preferred because of their heat delivery in the sites where other pumps are not able to deliver. The low temperature can go to -30 Celsius, but they can produce energy with their electric boilers.

What are high temperature heat pumps?

High temperature heat pumps are a technical type of air source that can deliver water at a good temperature.

Its efficiency is modern and attached to modern gas boilers. As a standard heat pump, it supplies water with heat around 35 to 55 degrees Celsius, and all models with high temperature extract heat with the help of a compressor.

How do High Temperature Heat Pumps Work?

The high temperature heat pumps can work for R410a and R32 at a temperature of 

-45 °. A heat pump transfers heat from outdoors to indoors and also absorbs heat from the air with its natural process. This air is converted into heat with the compressor, increasing the temperature, and also transfers heat into water with the traditional radiator and hot water cylinder.

These are high-temperature pumps with advanced technology to reach higher points of water temperature. In the UK, high-temperature pumps are used with different compression cycles, and these are individually different and able to boost temperatures to 75 °C.

High Temperature pumps

High-temperature heat pumps are worth it. 

These heat pumps have different temperature models and are ideal for homeowners. But at the same time, these are costly for other homeowners. There are some stages where they make sense and are suitable. 

They are most suitable for homes : 

• These are connected with old radiators and designed to attach to high high-temperature boilers.
• If the house is big and requires a high heating system.
• Also best for homes whose previous connection is an oil boiler or LPG.
• And for homeowners who want no disruption while installing.

When it’s not worth installing high temperature Heat pumps

• When the home is already insulated with a well-designed system.
• Radiators that are attached are modern and accurate in size.
• It is not worthwhile for the homes that are constructed recently and are new.

Running Cost of high temperature VS standard heat pumps

When you compare running costs, it’s usually found that:

High temperature heat pumps 

They are consuming more electricity than other or standard heat pumps because their work efficiency is higher, and they provide the best water temperature. However, these are also known as more reliable than traditional gas boilers.

Standard heat Pumps

On the other hand, these operate with lower temperatures and also help to work more efficiently and also help to reduce energy bills. As a result, Homeowners who always want low energy bills prefer standard heat pumps.

High temperature COP:

Normally 2.2 to 2.8

Standard heat pump COP:

Normally 3.2 to 4.0

Is this reliable for the UK in cold weather?

These heat pumps are manufactured to withstand stronger conditions to maintain the water temperature at higher temperatures, even when it is cold in the UK.

Moreover, the maintenance of temperature in winter is also a challenge, but it consumes more electricity to maintain the temperature, and as a result, the cost rises.

Alternative heating pumps

Standard air source heat pumps

Standard air source heat pumps still deliver the best heating temperature and consume less energy after installation is accurate.

Hybrid heat pumps

These heat pumps always keep the boilers in place. However, you can also use it even if it’s connected to a boiler or a heat pump. It provides high temperature with less running cost.

How hot water performance?

However, this system of a heat pump is slower than a combi boiler, but at the same time it is more similar to traditional systems and delivers hot water as fast as it can.

Pros and Cons 

Pros

• It’s most compatible with old radiator work.
• No requirements for Piper upgrades or radiators.
• Best and most reliable for big and old manufactured homes.
• A good alternative to oil and LPG boilers in different homes.

Cons

• High in running costs.
• The installation cost is also high.
• Outer space is required for the unit to be placed.
• It always follows electricity prices and is volatile at the same time.
• The efficiency is not higher than standard heat pumps.

High temperature heat pumps and boiler upgrades Scheme

As this scheme comes, it is provided to all homeowners with £7,500 if eligible.

And this grant is for an air source. Pump installation is done with models of high temperature.

With S6 energy, you can easily qualify to get this grant through this scheme. Teamwork efficiently provides the best results, and you can reach us through our website.

Installation requirements or upgrading needs

When it comes to high temperature systems then everyone should come to know that: 

 It always works with existing radiators to reduce disruption, and it’s the best part of it. So there are some requirements to fulfil by homeowners to install it.

• For these heating pumps, you should attach a hot water cylinder, which is more suitable for them.
• Outer space is also required for the external unit.
• Accurate pipe sizing between the pump and the cylinder is also required.

Conclusion

High-temperature heat pump is always worth it for homes that are not able to upgrade radiators, so that it can connect easily. However, they work particularly effectively for old manufactured homes and big houses that have recently shifted from oil or LPG boilers to electric. Modern insulated UK homes prefer to use standard heat pumps because they are cheaper and provide low running costs, but these high temperature heat pumps are also worth it to consume less electricity and work efficiently in cold weather.

Still, if you want help to get to know about the best system that matches your home, you can reach us. S6 energy can access all your needs and will recommend the most compatible heating system for you.

FAQs

What is the exact lifespan of high high-temperature heat pump?

High-quality heat pumps typically last for 15 to 20 years with proper care and maintenance.

Is it required to replace the entire heating system to install high high-temperature pump?

No, however, you do not need to replace everything because these heat pumps are consequently compatible with existing radiators and their pipe connections.

Do these heat pumps work efficiently in cold weather conditions?

Yes, it is, they are manufactured to control and maintain heat in cold weather, although energy consumption can increase when the temperature goes down.

Can we use these to make our home cool in summer?

Yes, with a reversible mod, it is possible to cool down the home temperature in summer, and it will work as an air conditioner and release all the heat from inside.

Are high-temperature heat pumps’ cost worthwhile running?

The running cost of these heat pumps is higher because they consume more energy to work efficiently than gas boilers.
