Hitachi Yutampo II


Yutampo systems are a DX split system with integrated electric auxiliary heating as standard. They are an energy saving and efficient water heating solution. The systems consist of a heat pump unit to heat water and a hot water unit to store water.

Yutempo heats water efficiently with less electrical power offering effective savings on energy compare to  conventional combustion type water heaters

The equipment absorbs heat from the outside air and transfers it to the tank to heat the water to 55C. That way, you can save up to 70% compared to traditional water heaters. In addition, the Split System avoids noise inside the house, while the outdoor unit can handle the most extreme weather, thanks to its Green Fin coating.

NOTE: Only for sale to F-Gas qualified engineers. Certificate must be issued to prior to purchase. Certificate must be valid and in the name of the purchasing company or engineer.

Note that this product is to be used for the production of  hot water only. Lead time is typically ten to fourteen days. Please check before ordering this product.

What you need to know!

The electricity consumption of your YUTAMPO II will be even lower if the coefficient of performance (COP) is high. YUTAMPO II has one of the best COPs on the market utilising 1kW of electricity and converting it into 3.2 kW of domestic hot water (DHW). (under standard rating conditions).

How does the heater work?
A thermodynamic water heater (The YUTAMPO II) works like a conventional heat pump. The outdoor unit of the YUTAMPO II solution removes heat from the air outside and transfers the heat to the water stored in the hot water tank.

Why use an outdoor unit?
The outdoor unit guarantees comfort without the noise. Once installed outside, the unit removes the heat from the air outside without cooling the house.

An eco-responsible commitment
The YUTAMPO II thermodynamic system produces more energy than it consumes, unlike conventional water heaters.


All installations of Yutampo systems must be carried out by F-GAS qualified engineers.

This installation will require the services of an F-Gas qualified Air Conditioning/ Refrigeration engineer. A sale will not be allowed without evidence of this and your payment will be refunded should the F-Gas certificate not be issued to The Yutampo product also requires plumbing installation which is likely to be a second trade on site

Commissioning reports must be returned to and approved to allow validation of warranty.

Features and Benefits:

  • A split system with integrated electric auxiliary heating as standard.
    • Stainless steel domestic hot water (DHW) tank with separate outdoor unit
    • Completely renewable energy system for domestic hot water
    • Converts 1kW consumption into an impressive 3.2kW output
    • Operates in outside temperatures as low as -15°C
    • Low noise
    • Simple to install, operate and service
    • Easy-to-use controller with ECO and boost modes, and timer and temperature settings as standard.

Features and Benefits:

Homes with no gas supply which require additional hot water storage. For example: another part of the home where the existing energy-efficient hot water and heating systems is not easily accessible

Commercial premises which require constant low temperature (50 degrees C) hot water. Example, Hairdressers, delicatessen, restaurant.

This product is best used in an environment where a nightime,  low-tarrif electrical supply is available. The product is designed to re-heat the cylinder overnight on the lower tarrif, thus reducing running costs.

This product is not recommended in applications where constant moving hot water supply is required. Example: care homes.
