Cheap high temperature heat pump : TOP 5

If you're renovating an older home fitted with radiators that require 60-65°C water temperature to deliver their power, one solution for switching to renewable energies is to install a high-temperature heat pump. This will enable you to make some energy savings, benefit from government subsidies, and not lose out on thermal comfort.

High-temperature heat pumps are used when the temperature of the hot water leaving the heat pump's condenser is around 60°C or 65°C. Some heat pumps, such as the Yutaki S80 or the Daikin Altherma 3H HT, can go even higher, to 80°C, then we speak of 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 heavyweight in the heating and air-conditioning sector. The company celebrates its 100th anniversary in 2021 and has around 120,000 employees worldwide, including almost 2% of researchers. Annual sales are around €40 billion.

The Japanese brand develops its own technologies thanks to its army of researchers (around 2000). In particular, it markets the Zubadan (an expression that means "super heater" in Japanese 🙂 ).

Thermal performance of the Zubadan Silence R32

The Mitsubishi Zubadan is capable of delivering water up to 60°C even when it's very cold outside, down to -7°C. And it can 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 heat 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

3 Very high temperature heat pumps

In addition to high-temperature heat pumps, which already enable you to keep your old radiators, there are air/water heat pumps that can reach even higher temperatures: 75-80°C. This offers even greater comfort, while remaining as thermodynamic as possible, i.e. without the use of electric resistance.

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

Hitachi Yutaki S80

This high-temperature heat pump is capable of maintaining its output down to -25°C, and can supply water up to 80°C. Perfect for renovating old houses with radiators.
