Cheap high temperature heat pump : TOP 5

If you are renovating an old house equipped with radiators requiring 60-65°C water temperature to deliver their power, a solution to switch to renewable energy is to install a high temperature heat pump. This will allow you to save some energy, to benefit from the state's incentives, and not to lose in thermal comfort.

We speak of a high temperature heat pump when the temperature of the hot water leaving the condenser of the heat pump is around 60°C or 65°C. Some heat pumps, such as the Yutaki S80 or the Daikin Altherma 3H HT, can reach even higher temperatures, up to 80°C, which is referred to as very high temperature.

In this article we present 5 models of cheap high temperature heat pumps available on the market.

5 cheapest high temperature heat pumps

Mitsubishi Zubadan Silence R32

Mitsubishi Electric is a heating and cooling heavyweight. The company turned 100 years old in 2021 and has about 120,000 employees worldwide including almost 2% researchers. Their annual turnover is about 40 billion euros.

The Japanese brand develops its own technologies thanks to its army of researchers (about 2000). It markets in particular the Zubadan (it is an expression which means "super heating" in Japanese 🙂 ).

Thermal performance of the Zubadan Silence R32

The Mitsubishi Zubadan is able to provide water up to 60°C even when it is very cold outside, down to -7°C. And it is able to maintain its heating power down to -15°C outside.

The COP on the best selling model (the 8kW) is just over 5 A7W35.

This Zubadan Silence R32 is available in 7 sizes from 8kW single phase to 14kW three phase.

See Mitsubishi Zubadan technical sheet

Notable technical features of this Zubadan Silence R32 high temperature heat pump model

There are several technical details that make it a competitive heat pump:

• Guaranteed to work down to -28°C (perfect for heating your tent at Everest base camp ;))
• Sound pressure of 42dBA at 1m and 28dBA at 5m: very quiet (value for the Zubadan silence 8, of 6kW...after that it goes up of 2dBA every two sizes)
• Available in split heating only, and also with integrated DHW 170L, 200L or 300L depending on the number of people and bathrooms
• Self-adapting control: it measures the difference between the set temperature and the actual room temperature, and adapts the heating flow to reach the required set temperature.

Price of the Zubadan Silence R32 Mitsubishi

You will find this heat pump from a little less than 6000€. for the smallest size 8 and up to about 8500€. for the biggest one.

3 Very high temperature heat pumps

Beyond the high temperature which already allows to keep old radiators, there are air water heat pumps which are able to go even higher in temperature: 75-80°C. This offers even more comfort, while remaining as much as possible in thermodynamic operation, i.e. without using electric resistance.

Here are three models that should make you happy if you are looking for this kind of performance.

Hitachi Yutaki S80

This model of high temperature heat pump is able to maintain its power until -25°C, and can provide water until 80°C. Perfect for a renovation of old house on radiators.

Daikin Altherma 3H HT

This high-temperature heat pump model, a real star on the European market, needs no introduction.
